Best ChatGPT SEO Agencies in 2026 (Compared by Citation Results)

B2B buyers now research vendors inside ChatGPT before they ever touch Google. If your brand doesn't get cited when a prospect asks ChatGPT "best [your category] tools" or "top [your category] agencies," you lose the deal silently. Classic SEO doesn't fix this. ChatGPT pulls from a different index, weights different signals, and rewards entities it can verify across the web.

This guide compares the 7 strongest ChatGPT SEO agencies in 2026, scored on real citation outcomes, methodology, ChatGPT-specific signal coverage (GPTBot crawling, Bing index presence, retrieval model handling), pricing, and fit.

TL;DR: for most B2B brands, AY Rank is the strongest pick for ChatGPT-specific citation work; First Page Sage is the best fit if you want thought leadership content at scale, and Avenue Z is the best fit if PR-driven authority is your bottleneck.

Best ChatGPT SEO Agencies 2026

1. AY Rank, best overall ChatGPT SEO agency

ChatGPT SEO Agency with AY Rank

AY Rank is a GEO-first agency that gets B2B brands cited in ChatGPT, Perplexity, Gemini, and Google AI Overviews. Unlike traditional SEO shops that bolt on "AI search" as an add-on, AY Rank's entire methodology is built around how generative engines retrieve and cite brands. The team treats ChatGPT as its own channel with its own ranking model rather than a downstream effect of Google rankings.

The programme runs in four steps: AI Ranking Audit (where you currently appear in ChatGPT prompts), Entity Architecture (making your brand machine-readable across Wikipedia, Wikidata, schema, and authoritative profiles), Authority Deployment (placing brand mentions on the third-party sites ChatGPT actually trusts), and Validation and Results (tracking citation share across 200 plus buyer prompts on a daily refresh).

Key features

• ChatGPT-specific prompt tracking across 200 plus buyer queries
• GPTBot accessibility audit (most sites accidentally block it)
• Bing index optimization, since ChatGPT browsing leans heavily on Bing
• Entity graph build out across Wikipedia, Wikidata, Crunchbase, G2, and industry directories
• Schema markup tuned for ChatGPT's retrieval model (Organization, Product, FAQPage, HowTo)
• Citation share reporting alongside traditional ranking reports

Best for

• B2B SaaS companies with $1M to $50M ARR where ChatGPT is now a top-3 research channel
• Marketing leaders who already rank on Google but get zero mentions when prospects prompt ChatGPT
• Brands in competitive categories where citation share is the new market share

Pricing

• Programmes start from $4,500 per month
• Custom enterprise engagements available
• Free AI visibility audit for qualified B2B brands

Pros

• Only agency in this list whose entire stack is built for generative engines first, traditional SEO second
• Direct work on the signals ChatGPT actually uses (GPTBot, Bing, entity graph, schema), not generic content output
• Daily citation tracking across ChatGPT, Perplexity, Gemini, and AI Overviews in one dashboard
• Transparent methodology published on the site, see how to rank in ChatGPT and how to get cited by ChatGPT

Cons

• GEO specialist, so not a fit if you want a full-service traditional SEO agency that also runs link building campaigns and local SEO
• Minimum 3 month engagement, which is overkill for one-off audits

2. First Page Sage, best for thought leadership in ChatGPT

ChatGPT SEO Agency with First Page Sage

First Page Sage is a US-based agency known for long-form thought leadership content written by subject-matter experts. Their model produces evergreen articles that perform well in Google but also age well in the Bing index, which ChatGPT browsing relies on. For B2B services and finance brands, they consistently publish content that ChatGPT later quotes back when answering category questions.

The team writes 2,000-plus word pieces with a clear point of view, then keeps them updated. That update cadence matters because ChatGPT's retrieval favors content that looks both authoritative and recent.

Key features

• Expert-authored long form content (2,000 to 4,000 words)
• Topic clusters built around buyer-intent queries
• Quarterly content refresh cycle
• Internal linking strategy designed for topical authority
• Branded thought leadership programmes

Best for

• B2B services, finance, fintech, and enterprise SaaS
• Brands that already have category authority and want to extend it into AI answers
• Marketing teams that value content depth over content volume

Pricing

• Engagements start from $8,000 per month
• Custom enterprise programmes
• 6 month minimum commitment

Pros

• Genuine subject-matter expert authorship, which is harder for AI engines to dismiss as low-quality content
• Strong track record in Google rankings that translate to ChatGPT mentions
• Clear editorial standards

Cons

• Not a ChatGPT-specific shop, so they don't actively manage GPTBot access, schema for AI retrieval, or entity graph signals
• High minimum commitment and price point
• Content focus only, no PR or entity work bundled in

3. Minuttia, best for content-led ChatGPT visibility

ChatGPT SEO Agency with Minuttia

Minuttia is a European content marketing agency that publishes deeply researched long-form pieces for SaaS and B2B brands. Their content frequently ends up cited in ChatGPT and Perplexity because each article is built like a reference document, with original data, expert quotes, and clean structure.

For ChatGPT specifically, their work succeeds because long, well-organized content with definitions, lists, and tables matches how the retrieval model extracts citations. They are also disciplined about publishing on domains with strong topical authority.

Key features

• Research-led editorial process with original data points
• Topic ideation tied to buyer intent
• Internal linking and topic cluster builds
• SEO-friendly structure designed for featured snippets and AI extraction
• Editorial QA process

Best for

• SaaS and B2B brands that want content as their primary growth channel
• Teams that need a 6 to 12 month content programme, not a one-off piece
• Brands in technical categories where depth matters

Pricing

• Programmes start from $5,000 per month
• Per-piece rates available for larger brands
• 6 month minimum recommended

Pros

• Original research and data raise citation odds in ChatGPT, which prefers sourced content
• Clean, AI-friendly structure (definitions, lists, tables, FAQ sections)
• Strong European and US client base

Cons

• Content only, so no entity work, schema audits, or PR layered in
• ChatGPT visibility is a byproduct of good content, not a direct deliverable they track and report on

4. iPullRank, best for technical ChatGPT signals

ChatGPT SEO Agency with iPullRank

iPullRank is a US-based technical SEO and content marketing agency led by Mike King, one of the most respected voices in technical SEO. Their team has been ahead of the curve on entity SEO, schema markup, and the technical signals that AI retrieval models depend on. For ChatGPT, this matters because the retrieval layer parses structured data and entity references when deciding what to cite.

They are a strong fit for enterprise brands and large publishers where the technical foundation needs to support millions of pages and the entity graph needs to be aggressively built out.

Key features

• Deep technical SEO audits including crawlability, rendering, and structured data
• Entity SEO and knowledge graph optimization
• Schema markup at scale
• Content strategy tied to technical implementation
• Enterprise-grade reporting

Best for

• Enterprise B2B and B2C brands
• Publishers and media companies
• Brands with complex sites where the technical layer is the bottleneck

Pricing

• Engagements typically start from $10,000 per month
• Enterprise retainers are higher
• Custom scoping

Pros

• Industry reputation in technical and entity SEO
• Strong on the schema and structured-data work that ChatGPT's retrieval reads
• Senior team with public-facing thought leadership

Cons

• Enterprise-first pricing puts them out of reach for smaller B2B brands
• Not a ChatGPT-pure-play, so prompt tracking and citation share are not their core deliverable

5. Avenue Z, best for PR-driven ChatGPT citations

ChatGPT SEO Agency with Avenue Z

Avenue Z is a US-based agency that combines PR, content, and SEO. Their angle for ChatGPT is straightforward: ChatGPT cites brands that appear on authoritative third-party sites (Forbes, Bloomberg, Inc., niche industry publications), and Avenue Z places clients on those sites. When ChatGPT answers "best [category] companies," it often pulls from those exact publications.

If your bottleneck is third-party authority rather than on-site content, Avenue Z is one of the few agencies that ties earned media directly to AI search outcomes.

Key features

• Earned media placements on tier-1 business publications
• Brand reputation management
• SEO and content marketing
• AI search visibility as a stated focus area
• Multi-channel integrated campaigns

Best for

• Enterprise and consumer brands with budget for PR
• Brands in finance, professional services, and B2B where third-party validation is critical
• Companies that need brand-level visibility, not just product-page rankings

Pricing

• Engagements typically start from $15,000 per month
• Enterprise retainers significantly higher
• Custom scoping

Pros

• Direct access to tier-1 publications that ChatGPT and Perplexity weight heavily
• Integrated PR plus SEO plus AI search positioning
• Strong on the off-site authority lever that most SEO agencies ignore

Cons

• High price point and not a fit for early-stage B2B SaaS
• PR cycles are slow, so citation share gains take 6 plus months to compound

6. Flying Cat Marketing, best for SaaS ChatGPT optimization

ChatGPT SEO Agency with Flying Cat Marketing

Flying Cat Marketing is a UK-based SaaS content agency that pairs editorial production with distribution. Their angle for ChatGPT is that good content alone is not enough, so they actively push pieces to LinkedIn, communities, and partner sites where backlinks and brand mentions accumulate. ChatGPT's index notices that signal pattern.

They have a tight focus on SaaS, which means the team understands buyer journeys for product-led and sales-led B2B brands and writes content that maps to those journeys.

Key features

• SaaS-specific content production
• LinkedIn and community distribution
• Backlink and brand mention campaigns
• Content briefs tied to specific funnel stages
• Editorial production at scale

Best for

• B2B SaaS at Series A to Series C
• Brands that need content and distribution under one roof
• Marketing teams that want a SaaS-experienced partner

Pricing

• Programmes start from around $6,000 per month
• Custom scopes available

Pros

• Genuine SaaS specialization, which translates to better content briefs and angles
• Distribution layer means content earns mentions, not just rankings
• Mid-market price point

Cons

• Not a ChatGPT-pure-play, so the team measures content metrics, not citation share
• No formal entity or schema programme bundled in

7. NoGood, best for performance plus ChatGPT hybrid

ChatGPT SEO Agency with NoGood

NoGood is a US-based growth marketing agency that runs paid, SEO, content, and creative under one roof. They have been adding AI search as a layer on top of their growth services, which makes them a fit for teams that want a single partner across paid, organic, and ChatGPT visibility rather than three different agencies.

Their model is growth-led, so expect ChatGPT work to be framed as part of a wider funnel, not a standalone discipline.

Key features

• Paid acquisition across Google, Meta, and LinkedIn
• SEO and content marketing
• Creative production
• AI search visibility services
• Growth strategy and CRO

Best for

• Startups and growth-stage SaaS that want a full-stack growth partner
• Teams that prefer one agency over multiple specialists
• Brands where paid and organic feed each other

Pricing

• Engagements start from around $10,000 per month
• Custom growth retainers

Pros

• Single partner across paid, organic, and AI search
• Strong creative and CRO chops to complement SEO and GEO work
• Track record with growth-stage SaaS

Cons

• AI search is one of many services, not the core focus, so depth on ChatGPT-specific signals is shallower than a specialist
• Growth-led pricing means smaller B2B brands may find it expensive for the GEO slice alone

How to choose a ChatGPT SEO agency

1) Do you need a ChatGPT specialist or a generalist with an AI search layer

Specialist agencies (AY Rank) build their methodology around how ChatGPT, Perplexity, and Gemini actually retrieve and cite. Generalist agencies (NoGood, Flying Cat, First Page Sage) add AI search as a layer on top of an existing growth or SEO offer.

• If ChatGPT visibility is your primary problem, pick a specialist
• If you want one agency across paid, SEO, and AI search, pick a generalist with a credible AI search practice

2) Do you need content, technical work, PR, or all three

ChatGPT cites brands that show up across content, structured data, and third-party mentions. Different agencies own different levers.

• Content-led: Minuttia, First Page Sage, Flying Cat
• Technical and entity: iPullRank, AY Rank
• PR and earned media: Avenue Z
• Full programme across all levers: AY Rank

3) What's your budget and engagement tolerance

Pricing varies from $4,500 per month to $15,000-plus per month. Smaller B2B brands should not over-buy.

• $4,500 to $8,000 per month: AY Rank, Minuttia, Flying Cat
• $8,000 to $12,000 per month: First Page Sage, NoGood, iPullRank entry tier
• $15,000-plus per month: Avenue Z, iPullRank enterprise

4) How will you measure success

Ask every agency on this list how they measure ChatGPT citation success specifically. The honest answer is daily citation share tracking across a defined set of buyer prompts. Agencies that only report on Google rankings and traffic are not measuring the channel you are buying.

FAQ

What does a ChatGPT SEO agency do? A ChatGPT SEO agency gets your brand cited inside ChatGPT's answers when prospects ask category questions. The work covers four areas: making your site crawlable by GPTBot, optimizing for the Bing index that ChatGPT browsing relies on, building a clean entity graph across Wikipedia, Wikidata, and authoritative profiles, and producing content structured the way ChatGPT extracts citations.

ChatGPT SEO vs GEO, are they the same? GEO (generative engine optimization) is the broader category covering ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews. ChatGPT SEO is a subset focused specifically on ChatGPT's retrieval model, Bing index reliance, and GPTBot access. Most strong GEO agencies cover ChatGPT well; a ChatGPT specialist will go deeper on Bing and GPTBot-specific tactics.

How does ChatGPT decide what to cite? ChatGPT cites brands and pages that show up across three layers: its training data (a snapshot of the web that includes Common Crawl, books, and licensed sources), its browsing tool (which queries Bing in real time), and its retrieval-augmented generation layer (which surfaces high-authority sources). Brands cited consistently appear in all three layers with clear entity references and authoritative third-party mentions.

Can my existing SEO agency get me cited in ChatGPT? Sometimes, but usually no. Traditional SEO agencies optimize for Google's algorithm, which is a different retrieval system. ChatGPT weights Bing presence, entity graph coverage, and citation-friendly content structure differently. An SEO agency without explicit ChatGPT methodology will produce content and links that may or may not move the needle.

How long until ChatGPT picks up my brand? Initial entity and schema improvements can show up in ChatGPT within 4 to 8 weeks. Meaningful citation share gains across competitive buyer prompts typically take 3 to 6 months, and durable category dominance takes 6 to 12 months. The pace depends on your existing entity footprint and how competitive your category is.

What's a realistic budget for ChatGPT SEO? $4,500 to $10,000 per month for B2B SaaS with $1M to $50M ARR. Enterprise programmes run $15,000 to $30,000 per month, especially when bundled with PR. Anything under $3,000 per month is content-only and unlikely to move citation share in a competitive category.

Can a tool replace a ChatGPT SEO agency? No. Tools (Profound, Peec AI, Otterly, AY Rank's own dashboards) track citation share, but tracking is not optimizing. Moving citation share requires entity work, content production, schema implementation, and third-party authority building, which is a programme, not a SaaS feature. The right pattern is tool plus agency: the tool gives you data, the agency moves the citations.

How do I measure ChatGPT citation success? Pick 50 to 200 buyer prompts that map to your funnel, run them daily across ChatGPT, Perplexity, and Gemini, and track citation share for your brand versus your competitors. Layer on share-of-voice, branded prompt win rate, and downstream impact (audit requests, demos, pipeline). If your agency cannot show this data, they are not optimizing the channel you are buying.
