B2B SEO is harder to evaluate than a rankings report makes it look. A useful agency has to understand long sales cycles, multiple decision-makers, technical constraints, content quality, authority building, and the growing role of AI-assisted discovery. The real question is not which agency can generate the most traffic. It is which one can connect organic visibility to qualified demand, pipeline, and revenue.

Quick answer: Uprankd is our best overall pick for B2B companies that want technical SEO, content strategy, authority building, international execution, and AI-search readiness under one strategy. First Page Sage is a strong alternative for U. S.-focused enterprise lead generation, iPullRank stands out for enterprise technical SEO and relevance engineering, and Grow and Convert is the specialist choice for bottom-funnel B2B SaaS content.

Disclosure: Uprankd publishes this comparison and is included in the ranking. That creates an obvious commercial interest, so the evaluation criteria and limitations are published below. Competitors are credited where their public evidence is stronger or their specialization is a better fit.

How We Evaluated the Best B2B SEO Agencies

This is an editorial comparison, not an independent audit of agency client accounts. We reviewed publicly available service pages, case studies, pricing information where available, and evidence of how each agency approaches B2B search. Vendor-reported results are described as published or agency-reported results rather than treated as independently audited facts.

We weighted the factors that matter most for complex B2B engagements:

B2B specialization and sales-cycle fit, 20%. Evidence that the agency understands long buying cycles, multiple stakeholders, and commercial search intent.
Technical SEO capability, 20%. Ability to diagnose crawl, rendering, indexation, architecture, JavaScript, internationalization, and large-site issues.
Content strategy and execution, 15%. Research quality, subject-matter expertise, editorial standards, and alignment with buyer intent.
Authority building, 15%. Digital PR, editorial link acquisition, brand authority, and off-page strategy.
AI-search readiness, 10%. A defensible approach to visibility across AI-assisted search without relying on unsupported GEO shortcuts.
International and complex-market capability, 10%. Experience with multi-market, multilingual, regulated, or technically demanding businesses.
Evidence and business measurement, 10%. Public case studies, transparent reporting, and a clear connection between SEO activity and business outcomes.

Uprankd ranks first on the combined criteria because its service mix covers technical SEO, content, authority building, multi-market execution, and AI-search optimization while keeping reporting tied to conversions and revenue. That does not make Uprankd the best choice for every company. Several agencies below are stronger specialists for narrower use cases.

Pricing changes frequently. Figures above reflect public information available at review time and should be confirmed directly with each agency.

1. Uprankd, Best Overall B2B SEO Agency for Pipeline & Revenue

What Uprankd Specializes In

Uprankd is a B2B SEO agency built for companies with long sales cycles, competitive search environments, and high-value customer relationships. Founded in 2018, the agency combines technical SEO, content strategy, authority building, international execution, and AI-search optimization rather than treating them as disconnected services.

Key Strengths and Services

The strongest reason to shortlist Uprankd is breadth without abandoning technical depth. The team works on crawlability, rendering, indexation, site architecture, canonicals, hreflang, JavaScript, large catalogs, and multi-language setups, then connects that technical foundation to content and authority-building work. Reporting is built around rankings and visibility, but also conversions and the pages that contribute to revenue.

That mix is particularly useful for B2B companies operating across multiple markets or working in regulated and technically demanding categories. It also reduces the handoff problem that appears when technical SEO, content, digital PR, and AI-search visibility sit with separate vendors.

Published Clients and Results

Uprankd's public client references include Georgia Facility Services, Notino, LM LAW OFFICE, Lāma Furnish, and Kärcher Latvia. A Notino testimonial describes an engagement that expanded from link building in one country to five markets and connects the work with improved traffic, client acquisition, and sales.

For technical SEO, Uprankd publishes an e-commerce recovery case study in which a site had lost nearly 45% of organic traffic over six months. The case study reports a 52% increase in organic sessions within four months, recovery of core product categories into the top 10, a 23% increase in click-through rate, a 75% reduction in crawl errors, and an 18% improvement in organic conversion rate.

Those results are not a B2B SaaS case study, and Uprankd's public library is smaller than several agencies below. We account for that limitation rather than treating every result on the site as interchangeable evidence.

Pricing and Engagement Model

Uprankd does not publish fixed SEO pricing. Engagements are scoped around the client's market, site complexity, growth objectives, and the amount of execution handled by Uprankd versus the internal team.

Ideal Client Profile

Best suited for mid-market and high-value B2B companies that want SEO treated as an ongoing growth channel rather than a fixed package of articles and links. The fit is strongest when technical SEO, international growth, authority building, and measurable commercial outcomes all matter at the same time.

When Another Agency May Be a Better Fit

Companies that need a deeply U. S.-centric enterprise B2B specialist, a pure B2B SaaS content agency, a very large enterprise consulting structure, or fixed public package pricing may find a stronger fit elsewhere on this list. That is why the specialist categories below matter.

2. First Page Sage: Best for Enterprise B2B Lead Generation & Thought Leadership

What First Page Sage Specializes In

First Page Sage is a U. S.-focused B2B SEO and GEO agency built around thought leadership, high-intent keyword targeting, conversion optimization, and lead attribution. Its 2026 B2B agency research describes the firm's specialty as B2B lead generation through SEO and GEO, with clients including Salesforce and U. S. Bank.

Key Strengths and Services

The agency's operating model combines technical SEO, keyword and intent analysis, expert-led content, conversion-rate optimization, and measurement. Its service pages emphasize building content around the questions high-value buyers ask across long sales cycles rather than optimizing purely for traffic volume.

First Page Sage also publishes a substantial volume of its own research and case studies. That creates a strong thought-leadership footprint and makes the agency a credible fit for companies that need consistent expert content as part of lead generation.

Published Clients and Results

First Page Sage publishes a long-running B2B SEO case study for iGPS reporting 230 leads worth approximately $15 million in lifetime value, 368 first-page keywords, and a conversion-rate increase from 0.04% to 0.22% over the campaign period.

Its newer SEO and GEO case study for a nearshore software development company reports an average $5.3 million per year in attributed revenue and AI recommendation share reaching 57% by year three. These are agency-published figures, not independently audited results.

Pricing and Engagement Model

Current First Page Sage pricing is not clearly published as a fixed service rate. The agency's own pricing research places comprehensive full-service SEO programs in the premium end of the market, but buyers should request a current quote rather than treating those market benchmarks as First Page Sage's price list.

Ideal Client Profile

Best suited for U. S.-focused B2B companies with high customer lifetime values, complex products, and enough internal subject-matter expertise to support a sustained thought-leadership program.

When Another Agency May Be a Better Fit

Companies that need a lower-cost or highly modular engagement, primarily international execution, or deep technical work without a major content program may prefer a different agency. First Page Sage's model makes the most sense when content-led lead generation is a central part of the growth plan.

3. Optimist: Best for Integrated SEO + AEO Pipeline Growth

What Optimist Specializes In

Tyler Hakes founded Optimist in 2016. The agency serves B2B technology companies from Series A through IPO, positioning itself at the intersection of traditional SEO and AI-generated answer visibility. AI Overviews now trigger on 82% of B2B tech queries, up from 36% a year earlier. Position-1 CTR drops 58% when one appears. For B2B companies, AI visibility now needs to be measured alongside traditional search performance.

Optimist covers both halves. Their work spans ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews alongside traditional search.

Key Strengths and Services

The methodology centers on the Complete Organic Revenue Engine (CORE) Framework, which maps SEO and AEO objectives across every buyer journey stage. The framework builds a unified topic universe scored by both search opportunity and AI visibility, then prioritizes actions by estimated pipeline value.

Services include:

Content structuring for AI extraction
Entity optimization
First-party data strategy
AI-referred pipeline attribution

The agency operates as a freelance collective. Senior strategists, writers, editors, and designers are hand-picked per engagement. Junior generalists do not cycle through accounts. This model keeps senior specialists involved throughout the engagement.

Published Clients and Results

Client portfolio includes Semrush, ZoomInfo, Superhuman, HelloSign, Stampli, and Glide.

The AEO results are specific and verifiable:

49x growth in LLM referral revenue over 14 months for a B2B technology company
8x growth in LLM conversions in 8 months for a fintech company
13x increase in LLM-sourced revenue year over year for a retail company

SEO-driven pipeline results follow the same pattern. Stampli's inbound pipeline grew 5X. Glide achieved 14x product signups in one year. Kubera reached 43x product signups in 15 months. Optimist's work also contributed to HelloSign's $230M acquisition by Dropbox, and for Plytix, content became the primary driver of leads and pipeline.

The value of those examples is that they report pipeline or revenue outcomes rather than traffic alone.

Pricing and Engagement Model

Advisory retainers start at $3,000/month. Full-service engagements begin at $4,000/month. One-time strategy projects start at $7,500. All engagements run month-to-month. A free organic revenue opportunity analysis is available before paid work begins.

Ideal Client Profile

Optimist works with B2B technology companies generating $2M to $500M in ARR that want AEO and SEO measured in pipeline and revenue from one provider.

When Another Agency May Be a Better Fit

Optimist is a boutique consultancy, so capacity is limited. Paid media is not offered, and Tyler Hakes' direct involvement constrains the number of simultaneous engagements. Companies that need a large full-service team across paid, organic, and creative will be better served elsewhere.

4. Omniscient Digital: Best B2B SEO Company for Product-Led SaaS

What Omniscient Digital Specializes In

David Ly Khim, Alex Birkett, and Allie Decker founded Omniscient Digital in 2019 after building SEO and content programs at HubSpot, Shopify, and Workato. That operator background shapes everything about how they run engagements. Programs get scoped backward from revenue goals, not forward from content calendars. The agency works exclusively with B2B software and SaaS companies, and the methodology reflects that focus: search and content tied directly to pipeline and ARR, not sessions.

Key Strengths and Services

The OmniscientX framework combines qualitative and quantitative research to identify positioning gaps, content opportunities, and client-specific strengths. Its Barbell Content Strategy balances product-focused pages designed to convert with broader editorial content designed to build authority. The aim is to avoid investing only in high-volume informational content or only in narrow bottom-funnel pages.

Services span SEO and content strategy, technical SEO consulting, programmatic SEO, content production and optimization, link building and digital PR, and thought leadership programs built from SME interviews. Generative Engine Optimization is included. The team embeds as an extension of in-house marketing rather than operating as a task-based vendor, and reporting is built to attribute organic efforts to qualified leads, pipeline, and revenue, not sessions.

Published Clients and Results

Client roster includes Jasper, SAP, Adobe, TikTok Shop, Asana, Loom, Hotjar, Order.co, AppSumo, and Smartling.

Published case studies report: Jasper's blog generated 810% organic session growth, 400X product signup increase, and over $4M in ARR. Order.co achieved 2,117% blog organic session growth and a 39X conversion increase; LLM-referred traffic on that account converted at 30% versus 5% for traditional search. Smartling generated $3.7M in qualified pipeline from organic, a 31,250% blog conversion increase, and 12.8X ROI. AppSumo recorded 843% organic traffic growth and 340% revenue increase. GatherContent grew organic sessions 867% and blog-attributed leads 62%.

The strongest evidence here is the connection between organic activity and reported pipeline or revenue outcomes.

Pricing and Engagement Model

Full-service engagements start at $10,000 per month. SEO and content strategy development packages begin at $15,000. Thought leadership strategy projects start around $3,000, ongoing written programs around $8,000 monthly, and multimedia thought leadership programs around $12,000 monthly.

Ideal Client Profile

Omniscient fits B2B SaaS and software companies with clear positioning, existing product-market fit, and marketing leadership prepared to treat SEO and content as long-term growth levers rather than quarterly experiments. Growth-stage and enterprise brands that want a strategic partner, not a content vendor, will find the model coherent.

When Another Agency May Be a Better Fit

Companies seeking low-cost content, guaranteed short-term results, or one-off articles without strategic context should look elsewhere. Teams without defined messaging, or those unconvinced that content and SEO can serve as primary growth channels, will find the engagement model a poor fit from the start.

5. Directive Consulting: Best B2B SEO Firm for Enterprise Tech Companies

What Directive Consulting Specializes In

Most B2B SEO agencies start with keywords. Directive starts with unit economics.

Their Customer Generation methodology builds SEO programs backward from ideal customer profiles and funnel strategy rather than forward from a keyword list. The approach targets mid-market to enterprise B2B companies across technology, industrial, and services verticals. SEO doesn't run in isolation here. It integrates with paid media, content marketing, conversion optimization, and revenue operations as one accountable system. Their GEO practice addresses AI-driven search through Stratos, an internal AI platform built to automate execution tasks so strategists focus on problem-solving rather than production.

Key Strengths and Services

Directive reports more than USD 1B in client revenue generated through its Customer Generation framework and says it invests USD 2.2M annually in marketing R&D. Its service mix includes technical SEO audits, content strategy mapped to buyer intent, digital PR link building, and reporting that connects organic performance to pipeline and revenue. Its DiscoverabilityOS methodology is built around visibility on the channels buyers use to research and shortlist vendors.

Internally, Directive's own SEO program grew page 1 keywords by 190%, generated USD 2.87M in non-branded closed-won revenue in a single half-year, and captured 24% share of AI brand mentions across tracked prompts. Agencies that can show their own results, not just client results, earn a different level of credibility.

Published Clients and Results

Client roster includes Wiz, Gong, PingCAP, Allstate, Amazon, Uber Freight, and Calendly. Omnipresent achieved their best month for closed deals after Directive cleaned up attribution and implemented offline conversion tracking. Eden Health saw 78% more conversions at 52% lower cost per lead through portfolio bid strategies.

Pricing and Engagement Model

Directive operates on strategic retainers with performance-based components. Across 56 verified Clutch reviews averaging 4.8/5, the most commonly reported project cost sits between USD 10,000 and USD 49,000, with some engagements reaching USD 60,000+ annually.

Ideal Client Profile

Best suited for B2B companies with USD 10M+ ARR that want SEO, paid media, and revenue operations functioning as one integrated demand generation program rather than separate line items.

When Another Agency May Be a Better Fit

Community discussions flag premium pricing that can exceed value for mid-tier clients, along with concerns about account team turnover and how consistently senior attention gets allocated. Companies where technical SEO depth or AI search optimization is the primary need may find agencies with narrower specialization more aligned. Directive's strength is integration. If you only need one channel managed, that's not what they're built for.

6. Grizzle: Best B2B SEO Specialist for End-to-End Content Engines

What Grizzle Specializes In

Grizzle has operated as a B2B organic growth agency since 2016. It builds content programs across Google, ChatGPT, YouTube, and other discovery platforms, with strategy, production, and distribution managed as one system.

Grizzle positions content as an operating system rather than a queue of deliverables. Their methodology embeds directly into client workflows, scaling multiformat programs alongside marketing, product, and customer success teams rather than operating as a separate vendor delivering deliverables.

Key Strengths and Services

Capabilities span SEO and GEO strategy, expert-led editorial and video content production, digital PR campaigns built from original research, YouTube and video production, content optimization, and translation for market expansion.

The research process is more disciplined than most. Grizzle conducts SME interviews and uses SparkToro to identify relevant thought leaders and publications for digital PR placement, not generic outreach lists. Their proprietary Cloudkicker platform orchestrates high-volume content programs through AI-enabled workflows. Every engagement pairs clients with experienced strategists, editors, and channel specialists. No generalist account managers cycling through accounts.

Published Clients and Results

Client roster includes Pipedrive, Semrush, Tipalti, Tide Banking, SmileBack, Web.com, and ReferralCandy.

Grizzle publishes the following client results: Pipedrive achieved 39% global revenue growth, a 4X traffic increase, and a 33% rise in user sign-ups. SmileBack recorded a 47% revenue increase. Semrush saw 64% growth in non-branded search traffic across 160+ articles. Tide generated a 112% search traffic increase and 5,000 ebook sign-ups through 152 articles.

Grizzle reports a three-year average client tenure.

Pricing and Engagement Model

Digital PR retainers typically start between $3,000 and $5,000 monthly, scaling to $15,000+ for comprehensive programs. Fixed-scope campaign sprints begin at $10,000.

The model is designed for sustained programs rather than short one-off assignments.

Ideal Client Profile

Grizzle fits B2B SaaS brands that treat organic growth as a system, not a campaign. The agency works best when clients are committed to multiformat execution across channels rather than looking for isolated content wins with a defined end date.

When Another Agency May Be a Better Fit

Grizzle is not the right fit for companies that want quick project work, guaranteed short-term results, or agencies that separate video and digital PR from their SEO strategy. Specialists in those narrow areas will serve those needs better.

7. iPullRank: Best for Technical SEO and Relevance Engineering

What iPullRank Specializes In

Most SEO agencies talk about AI search. iPullRank built a framework for it. Founded by Mike King in New York, the agency operates at the intersection of enterprise technical SEO and AI search visibility, grounding its work in how retrieval systems actually function rather than how practitioners assume they do. The agency claims USD 5B+ in organic search results delivered for clients including American Express, SAP, Nordstrom, Adidas, Target, Warner Music Group, and the Wall Street Journal.

Key Strengths and Services

The agency's differentiator is Relevance Engineering, a methodology that connects AI, information retrieval, content strategy, digital PR, and user experience into a single framework for influencing brand visibility inside AI search environments. iPullRank treats these workstreams as one technical and strategic system.

The proprietary tooling reflects this: Qforia for query simulation, Orbitwise for vector-space relevance scoring, and Relevance Doctor for content relevance testing. The approach is grounded in patent analysis, embedding models, and cosine similarity, not keyword density and content calendars.

Services cover technical SEO audits addressing crawl and architecture problems, passage-level content engineering, and AI search transformation for marketing teams building RAG-powered content systems. The work requires internal teams capable of implementing recommendations. iPullRank diagnoses and directs. Execution sits with the client.

Published Clients and Results

Its published case studies report the following results.

A major bank paused paid ad spend based on content engineering success and recorded USD 2.4B in incremental revenue. A global eCommerce marketplace generated USD 290M in revenue through AI-generated category page content that produced a 167% traffic lift. A financial services organization achieved a 121% cumulative sign-up increase and 52.6% organic traffic growth, with 17x higher conversion on pages showing improved Relevance Scores. A telecommunications brand grew from 712 to 3,235 AI Overview inclusions in one year, 253% growth, earning 1.41M impressions.

The published case studies connect technical interventions with revenue and conversion outcomes.

Pricing and Engagement Model

The flagship 6-month enterprise engagement starts at USD 150K. Minimum project size begins at USD 50K+. The pricing reflects enterprise-level strategic diagnosis rather than routine content production.

Ideal Client Profile

Best suited for enterprise and mid-market brands with dedicated internal marketing teams who can implement strategic recommendations. The agency produces the thinking. Your team does the building. That division needs to be clearly understood before engaging.

When Another Agency May Be a Better Fit

Budgets below USD 50K, teams needing hands-on iterative execution, or businesses where conversion rate optimization takes priority over technical infrastructure will find the model misaligned. iPullRank is a high-investment, high-ceiling engagement. Companies that need steady monthly output rather than structural diagnosis should look elsewhere.

8. Seer Interactive: Best Full-Service B2B SEO Agency with GEO

What Seer Interactive Specializes In

Wil Reynolds founded Seer Interactive in 2002. The Philadelphia-based agency has since built one of the more credible AI research practices in the SEO industry, publishing studies since January 2023 that Forbes, eMarketer, Fast Company, Search Engine Land, and Ahrefs have cited. This gives Seer's GEO positioning a stronger research base than a generic service claim.

Their research documents specific patterns: organic CTR declines 67% when brands aren't cited in AI Overviews, while pre-selected brands show 5x higher citation likelihood. Since January 2025, 15% of Seer's own inbound conversions have originated from LLM referrals. They're not just advising clients on AI search. They're running the same experiments on themselves.

Services cover organic search, generative engine optimization, paid media, analytics, and creative. Full-service in the genuine sense.

Key Strengths and Services

Seer's main differentiator is its data infrastructure. The agency reports maintaining 8.2B rows of SERP data. Its SeerSignals platform combines that data with consultant analysis to support search decisions at enterprise scale.

Their GEO practice launched in 2024 and partners with Scrunch for AI search visibility tracking across platforms. Services span audience-driven insights, keyword and content strategy, technical SEO including site migrations, and KPI reporting focused on ROI rather than rankings alone.

Published Clients and Results

Seer works across SaaS, healthcare, banking, ecommerce, and higher education, serving 400+ brands. Published case studies report a 50% increase in organic purchases through seasonality analysis, 16% year-over-year growth in appointment requests through big data analysis, and a 23% traffic increase through strategic content pruning that reversed five years of decline.

One published case study shows a 23% traffic increase after content pruning reversed a five-year decline. It is a useful example of Seer's willingness to remove weak content when the data supports it.

Pricing and Engagement Model

Seer operates at enterprise scale with scoped project pricing rather than fixed rates. Expect to scope before you see a number.

Ideal Client Profile

Seer fits large professional services sites and enterprises that need analytics-heavy experimentation, deep testing, and integrated channel strategies. The data infrastructure only pays off when clients can act on what it surfaces.

When Another Agency May Be a Better Fit

Predictable fixed-rate pricing isn't available here. Neither is rapid execution without extensive analytics groundwork. Companies that need to move fast or want simple monthly retainers should look elsewhere.

9. Siege Media: Best for Content Marketing and Digital PR at Scale

What Siege Media Specializes In

Ross Hudgens founded Siege Media in 2012. Over the past decade, the agency built its reputation on one specific combination: content marketing, digital PR, and technical SEO operating as a single system rather than separate services.

The positioning is deliberate. Siege claims to be the only full-service GEO agency integrating all four disciplines, technical SEO, content creation, digital PR, and generative engine optimization, under one roof. The client list and traffic value numbers give it some weight: the agency generates over USD 148 million in annual traffic value across SaaS, fintech, and e-commerce clients.

Their methodology accounts for where search is actually going. LLM-driven insights feed into SEO workflows, and content is built to maintain visibility across both traditional organic results and AI-driven answers.

Key Strengths and Services

Siege uses two proprietary systems internally. BlueprintIQ maps search and generative visibility opportunities. DataFlywheel manages content updates through a four-phase, data-backed process. Both are designed to guide content investment decisions.

Account structure uses dedicated pods of 4-6 people per client. The model keeps work contained within a consistent team rather than routing tasks through a generalist pool.

Services cover product-centric SEO consulting, content marketing at scale, digital PR through earned media relationships, and link building. The digital PR work connects to proprietary data, which creates co-citation patterns that inform how AI search engines understand brand positioning.

Published Clients and Results

Client roster includes Asana, Intuit, Airbnb, Zillow, Zapier, Zoom, Figma, Zendesk, Instacart, Purple, and Casper.

Published case studies report: Figma's Resource Library grew 2,065% in traffic. Readers.com grew 65% year-over-year through infographics picked up by over 200 websites. Sunglass Warehouse achieved 20% year-over-year organic traffic growth.

The results skew heavily toward content-driven traffic. That's consistent with what the agency does well.

Pricing and Engagement Model

Retainers start between USD 8,000 and USD 11,000 monthly, with full-service engagements ranging from USD 12,000 to USD 30,000 monthly depending on scope.

Siege publishes two important engagement conditions. First, the agency requires 400%+ projected ROI before accepting a client. That requirement screens out engagements where the economics are unlikely to work. Second, engagements typically run 12-month commitments. That commitment can be restrictive for teams with shorter planning horizons.

Ideal Client Profile

Well-funded mid-market to enterprise companies in SaaS, fintech, e-commerce, or health. The budget range and 12-month commitment structure rule out early-stage teams. The ROI requirement rules out anyone uncertain about whether content and search are the right levers for their business.

When Another Agency May Be a Better Fit

Client feedback points to two recurring friction points: slower communication during sales processes and project management extensions that stretch timelines and budgets. Neither is disqualifying on its own, but both are worth factoring in if your internal team operates on tight delivery cycles.

A limitation is that Siege's model prioritizes content volume and digital PR reach over deep technical SEO and programmatic frameworks. For sites with significant crawl architecture problems, heavy JavaScript dependencies, or large-scale duplication issues, an agency specializing in technical diagnosis will be better positioned to address the root causes before layering content investment on top.

10. Victorious: Best B2B SEO Experts for Link Building and Domain Authority

What Victorious Specializes In

Five-time SEO Agency of the Year. That recognition reflects a consistent focus on authority development and ethical link acquisition rather than a broad service portfolio. Victorious coordinates SEO work around the specific products and services clients sell, building credibility through entity associations and competitive gap closure rather than generalized traffic plays. The technical and content work connects to AI-driven search platforms alongside traditional search, treating discovery as a unified problem rather than separate channels.

Key Strengths and Services

Content clusters map to commercial priorities. The structure answers buyer questions and moves them toward conversion rather than informing and losing them. Technical capabilities cover crawl error resolution, duplicate content fixes, and schema implementation that helps search systems interpret what a page is actually about.

Victorious also addresses AI retrievability through structured content and clearer entity signals, using the same technical and content foundations that support ordinary search visibility.

Published Clients and Results

Client work spans law firms, multi-location businesses, and B2B service providers. A law firm achieved a 19% case volume increase through a combination of technical SEO, content marketing, and local optimization. One client reported revenue increasing tenfold. These are not SaaS ARR case studies. The evidence base reflects the types of businesses Victorious actually serves.

Pricing and Engagement Model

Victorious recommends a minimum of $6,000 monthly with 12-month campaign commitments. Most B2B clients invest between $6,000 and $35,000 per month, with pricing scaling based on the number of products or solutions requiring optimization. Early ranking movement typically appears within 3-4 months. Meaningful pipeline impact tends to emerge in 6-9 months. Treat those timelines as the agency's engagement expectations rather than a universal SEO benchmark.

Ideal Client Profile

Best suited for B2B companies treating authority building and link acquisition as core growth strategies. Budgets need to support 12-month engagements. Expectations need to align with 6-9 month pipeline development timelines before organic search starts contributing at scale.

When Another Agency May Be a Better Fit

Companies requiring specialized AI search optimization beyond foundational retrievability improvements should look at agencies where that work is the primary focus rather than an add-on. Businesses seeking extensive published SaaS case studies with documented ARR growth will find limited direct evidence here. The client base skews toward professional services and multi-location businesses. That makes the fit less direct for SaaS buyers.

11. Grow and Convert: Best for Bottom-Funnel Pain Point SEO

What Grow and Convert Specializes In

Benji Hyam and Devesh Khanal built Grow and Convert around a single rejection: traffic volume is not content success. The agency focuses exclusively on conversion-focused content for B2B SaaS companies, targeting high-intent keywords that produce leads, demo requests, and trials rather than sessions.

Their Pain Point SEO methodology works across three keyword tiers. Category keywords average a 4.85% conversion rate. Comparison and alternative keywords hit 8.43%. Jobs-To-Be-Done keywords address the specific problems a product solves. The model prioritizes commercial intent over informational volume.

Key Strengths and Services

Grow and Convert starts content production with interviews of client subject-matter experts before selecting and developing topics. The process is designed to capture product knowledge and buyer pain points that would be missed by desk research alone.

Services include bottom-funnel keyword targeting, paid ads and link building for content promotion, GEO strategy focused on product-centric content, conversion tracking from both SEO and AI sources, and AI visibility tracking through their proprietary tool Traqer.ai. The process inverts the typical sequence: buyer intent and pain points first, keywords second.

Published Clients and Results

Grow and Convert generated 1,745 free trial signups while ranking for 26+ buying-intent keywords. A nonprofit client doubled organic traffic and grew organic conversions by more than 10 times. The Leadfeeder case study showed steady month-over-month conversion increases sustained for over a year after implementing the Pain Point SEO framework.

The emphasis is conversion output rather than traffic volume.

Pricing and Engagement Model

Engagements run at $10,000 per month for content and SEO strategy. The interview-led methodology requires ongoing SME participation. If internal experts are unavailable or overextended, production slows. This can become a production constraint.

Ideal Client Profile

Grow and Convert fits B2B SaaS companies with subject matter experts who can commit weekly hours for interviews and are prepared to treat content as a revenue driver rather than a traffic metric.

When Another Agency May Be a Better Fit

The SME dependency creates production bottlenecks when internal experts are spread thin. Grow and Convert is a specialist content shop. Deep technical SEO is not in scope. Brands carrying significant technical debt or complex site architecture typically need a second agency to handle what Grow and Convert does not.

Companies requiring unified strategy across paid media, social distribution, and marketing automation will find gaps. That specialist model works best when content is the primary constraint.

How to Choose the Right B2B SEO Agency

1. Start With Pipeline Measurement, Not a Traffic Promise

Ask how the agency connects organic search to qualified leads, opportunities, sourced pipeline, influenced pipeline, and closed-won revenue. Rankings and traffic are useful diagnostic metrics, but they are not the end goal for a B2B company. The agency should be able to explain what it will measure, where the data comes from, and how it will separate leading indicators from commercial outcomes.

2. Check Whether the Agency Understands Your Sales Cycle

B2B search has to influence more than one person. A buyer may discover a vendor through an educational query, return through a comparison page, share the site with a technical evaluator, and only convert weeks or months later. A credible agency should ask about deal size, sales-cycle length, buying committees, product-market fit, and what your sales team considers a qualified opportunity before it proposes a keyword plan.

3. Match Technical Depth to the Complexity of Your Site

For a straightforward marketing site, basic technical competence may be enough. For a large, multilingual, JavaScript-heavy, migrated, or programmatic site, it is not. Ask who diagnoses crawl and rendering problems, how recommendations are prioritized, whether the agency can work with developers, and how fixes are validated after release.

4. Inspect How Content Is Actually Produced

For specialist B2B topics, the production process matters more than raw article volume. Ask whether writers interview subject-matter experts, how claims are sourced, who edits technical material, and how the agency decides which topics deserve a page. AI-assisted production is not automatically a problem; unverified, generic content is.

5. Understand the Authority-Building Model

Ask where links and mentions come from. Digital PR, original research, expert commentary, partnerships, relevant directories, and genuinely useful resources are very different from opaque monthly link quotas. If an agency cannot explain why a publisher would cite the material it creates, the authority strategy deserves scrutiny.

6. Treat AI Search as an Extension of Search Strategy, Not a Shortcut

A serious AI-search strategy should address crawlability, content quality, entity clarity, third-party corroboration, brand authority, and measurement of AI-referred visits or conversions where possible. Be skeptical of agencies presenting FAQ schema, prompt tricks, or a handful of rewritten headings as a complete GEO strategy. Traditional SEO foundations still matter because AI-assisted search systems frequently retrieve information from the open web.

7. Ask Who Will Actually Work on the Account

The pitch team and delivery team are often different. Ask for the names or roles of the strategist, technical lead, editor, and account owner; how many accounts they manage; and what work is done in-house versus outsourced. Senior involvement is only valuable if it continues after the contract is signed.

Red Flags to Avoid

Guaranteed rankings or guaranteed AI recommendations.
Traffic forecasts with no plan for lead or pipeline attribution.
AI-search claims with no methodology or measurable evidence.
Fixed link quotas without transparent sourcing standards.
Content production that requires no input from your team despite a highly technical product.
Reporting that lists activities completed but cannot explain what changed commercially.

FAQs

Is SEO still effective for B2B companies in 2026?

Yes, but the useful definition of SEO is broader than ranking informational articles. B2B SEO now includes technical accessibility, commercial-intent content, authority building, conversion paths, and measurement across longer buyer journeys. AI-assisted discovery adds another surface to monitor; it does not remove the need for strong web fundamentals.

How do I choose the right B2B SEO agency?

Start with your constraint. If the site has serious technical debt, prioritize technical depth. If the product is strong but the market does not understand it, prioritize content and subject-matter expertise. If competitors dominate third-party coverage, prioritize authority building and digital PR. Then ask each agency to show how its process connects that work to qualified demand and revenue.

What should a B2B SEO agency measure?

Useful reporting can include rankings, impressions, clicks, qualified organic sessions, demo requests, target-account engagement, MQLs, SQLs, opportunity influence, sourced pipeline, influenced pipeline, and closed-won revenue. Not every business can attribute all of these perfectly, but the reporting model should move toward commercial outcomes rather than stop at traffic.

What is the difference between SEO, AEO, and GEO?

SEO improves visibility and performance across traditional search. AEO and GEO are labels used for work intended to improve how a brand or its content is retrieved, understood, cited, or recommended in AI-assisted search experiences. In practice, there is substantial overlap: crawlability, useful content, clear entities, strong reputation, and third-party corroboration support both traditional and AI-assisted discovery.

How much do B2B SEO agencies cost in 2026?

There is no single market rate. Among agencies in this comparison, published entry points range from a few thousand dollars per month for advisory or focused work to five-figure monthly retainers and enterprise projects with $50,000+ minimums. Several agencies, including Uprankd, require custom scoping. Use the figures in the comparison table as directional signals, then request a current proposal based on the actual scope.
