Short answer: SEO Engico is the top pick for ChatGPT SEO if you want ChatGPT visibility judged on calls, enquiries and revenue, with the work included in an SEO retainer rather than billed separately. SearchAxe suits SaaS startups that want both of ChatGPT's routes worked at a modest published fee, MV3 Marketing suits teams that want every deliverable priced, SEOArmy fits US service businesses, and Shila is the fixed-price option for a single 12-week push.
ChatGPT SEO is the work of getting your business named, cited and described correctly when someone asks ChatGPT what to buy or who to hire. It is narrower than general AI search work, and that matters, because ChatGPT behaves in a particular way. When it searches the web, it reads live results and the pages that rank for the queries it writes. When it does not, it answers from what the model learned in training. An agency that only works on one of those routes is guessing about the other.
Every other agency here has a page dedicated to ChatGPT SEO or ChatGPT visibility, checked on its own website in November 2026. We judged them on what those pages say: whether they treat search answers and training-data answers differently, whether they check OpenAI's crawlers, how they track the visits ChatGPT sends, and what they charge where a price is published.

How we picked
- Treats search answers and training answers separately. With search on, ChatGPT reads current web results, so page and ranking work can move it within weeks. Without search, it leans on what the wider web said about you before the model's cutoff, which only changes with a newer model. The better agencies plan for both and say which moves first.
- Checks OpenAI's crawlers by name. OpenAI documents separate crawlers for ChatGPT search and for model training. A good agency checks robots.txt, CDN and firewall rules so the search crawler can reach your pages, and lets you decide about training access as a separate choice.
- Runs prompts more than once. ChatGPT can give different shortlists to the same question. Ask how many times each prompt is run, whether search is on or off, and how the agency logs who gets named, in what order and from which sources.
- Works on the sources ChatGPT trusts. Reviews, roundups, forums, press and comparison articles shape what ChatGPT says about a category. Look for agencies that map the sources behind current answers in your market and earn mentions there, not only rewrite your own pages.
- Reports ChatGPT referrals in your analytics. Visits from ChatGPT often arrive with a chatgpt.com referrer or tag, so they can be measured. Agencies worth paying will report those visits and tie them to enquiries, signups or sales, read against a baseline fixed before work starts.
The 7 best ChatGPT SEO agencies in 2026
Our top pick
1. SEO Engico
- Best for
- Businesses that want ChatGPT visibility judged on enquiries, inside one SEO retainer
- Based in
- London, UK
- Founded
- 2018
SEO Engico is a London agency founded in 2018 that works with trades, law firms, ecommerce brands and agencies in the UK, US, Australia and India. Its AI search work starts with a check most buyers skip: does ChatGPT name you when your buyers ask, and who does it name instead? It runs the same questions through Google AI Mode, Perplexity and Claude too, then works on what decides the answer. That means a site open to AI crawlers, pages with the answer near the top in words a model can lift, markup and profiles so AI tools know who you are and where, and mentions on trusted sites such as reviews, listings and coverage.
Its closest published proof is One Planet Migration Law, an Australian immigration firm. SEO Engico moved it to a new site without losing rankings, then built coverage of the questions migration applicants search, and its published figure is 13,274 organic clicks from Australia between 30 April and 29 July 2026 (Search Console), growing every quarter since measurement began. That is Google data, not ChatGPT data, but answer-first coverage of real questions is the groundwork both depend on.
AI search is included in the $4,500 a month Growth retainer, after a 30-day Revenue Baseline ($3,499) that traces calls, forms and closed deals back to the search that started them.
What stands out
- Tracks the questions buyers ask every month and reports who ChatGPT names instead of you
- ChatGPT work included in the SEO retainer, with technical SEO, content and link building in the same team
- Reports open with calls, enquiries and revenue rather than citation counts
- Free AI Visibility Checker covering ChatGPT, Perplexity, Gemini and Google AI Overviews
Worth knowing
- It never promises a specific citation. Page changes can show within weeks, while mentions on other sites take longer.
- ChatGPT is covered as part of wider AI search work, not sold as a ChatGPT-only service.

2. SearchAxe
- Best for
- B2B SaaS and startups that want ChatGPT measured in signups, at a modest monthly fee
- Based in
- Registered in the US
SearchAxe is led by Amit Malvi, who spent four and a half years at Invideo AI, rising to Senior SEO Manager and running its GEO and AEO programmes. Its ChatGPT SEO page explains the mechanics more clearly than most: without search, ChatGPT relies on what it absorbed in training, and with search on, it rewrites the prompt into queries and reads what comes back, drawing on Bing's index.
So the work runs on both tracks. It writes the shortlist prompts your buyers type and runs each several times with search on and off, works on Bing as well as Google rankings for the queries ChatGPT searches, checks robots.txt, CDN and firewall rules for OAI-SearchBot, and reports chatgpt.com referrals tied to signups and demos.
What stands out
- Published price: $1,499 a month for full-service SEO and AI visibility, three-month minimum
- Runs every prompt repeatedly, with search on and off
- Works on Bing rankings because ChatGPT search draws on Bing's index
Worth knowing
- Third-party costs, such as editorial or placement fees and paid listings, are paid by you directly.
- It works hands-on with a small number of B2B SaaS, tech and services firms and seed to Series B startups.
No. 3
3. MV3 Marketing
- Best for
- Teams that want a fixed-fee ChatGPT programme with every deliverable priced
- Based in
- Raleigh, North Carolina, US
MV3 Marketing's ChatGPT SEO page is built around one idea: ChatGPT has two surfaces, training-data recall and live browsing, with different crawlers (GPTBot and OAI-SearchBot) and different timelines, and most vendors only work on one. Before building anything, it checks whether your target queries tend to be answered from recall or from a live search, and delivers a written scope document.
The programme then ships quick-answer blocks for extraction, an llms.txt file it maintains, schema and JSON-LD, entity consistency checks, crawlability confirmation for both OpenAI crawlers, and monthly citation tracking against real ChatGPT answers rather than a modelled score. Katya Lishnievska, who leads its technical SEO operations, reviews every citation report.
What stands out
- Published pricing: a $997 GEO audit, then a programme from $2,497 a month
- Plans separately for training recall and live browsing
- Says plainly it will never promise a ChatGPT citation
Worth knowing
- The deliverables lean on on-site and technical work, so ask how much off-site mention building is included.
- It says training-data answers move on OpenAI's model-update timeline, which no agency controls.
No. 4
4. SEOArmy
- Best for
- US service businesses that want ChatGPT visibility and ChatGPT ads from one team
- Based in
- Seattle, Washington and Austin, Texas, US
SEOArmy is a growth agency for established service businesses, with pages for home services, healthcare, law firms, insurance and more, and it takes one client per trade per market. Its ChatGPT SEO work sits inside a wider AI search programme and starts with crawler access: it audits robots.txt, CDN and firewall rules for OAI-SearchBot, ChatGPT-User and GPTBot and sets each one deliberately.
From there it maps the prompts buyers ask ChatGPT, tests who gets recommended, builds the citations ChatGPT leans on (reviews, directories, industry lists, community threads and press) and rewrites key pages into clear answers with pricing context and proof. It also runs ChatGPT ads for categories that are eligible, kept separate from the organic answer.
What stands out
- Explains the difference between OpenAI's training, search and user crawlers
- Keeps business facts consistent across Google Business Profile, Bing Places and directories
- Free AI Visibility Report showing who ChatGPT recommends instead
Worth knowing
- No price is published on its ChatGPT page.
- Its industry pages are mostly US local and service sectors, so SaaS and ecommerce brands may find a better fit elsewhere.
No. 5
5. Shila
- Best for
- Startups that want one fixed-price, 12-week ChatGPT push rather than a retainer
- Based in
- Registered in Singapore, remote-first
Shila sells ChatGPT SEO as a $5,000 one-time, 12-week cycle instead of a monthly retainer. It starts with a ChatGPT citation audit that runs your buyers' real prompts and traces why you are or are not named, then fixes indexation, structure and entity issues before it scales content. Its page notes that ChatGPT's live searches lean on its Microsoft and Bing connection, so being well indexed there is part of the job.
Weekly execution happens in your Slack: Raya, as the page calls it, ships citation-ready content and technical fixes, a human strategist makes the judgement calls, and every page is human-reviewed before it publishes. You get a weekly report on how often ChatGPT cites you across your key prompts.
What stands out
- Fixed $5,000 price for a defined 12-week cycle
- Free 48-hour video audit before you commit
- Weekly prompt tracking and reporting in Slack
Worth knowing
- It describes its model as automation plus real human review, so it suits founders comfortable with that approach.
- It says it is not built for enterprises that need large on-site teams and procurement.
No. 6
6. Quirky Digital
- Best for
- UK brands in finance, SaaS or healthcare that need authority built off-site
- Based in
- Liverpool, UK
Quirky Digital is a UK SEO and GEO agency whose ChatGPT SEO service puts most of its weight on the wider web. Its view is that ChatGPT forms answers from what trusted sources say, so your brand needs to be recognised and referenced across the internet, not just optimised on your own site.
The work covers an SEO and LLM visibility audit, expert-led content that answers your audience's questions, digital PR and authority building in reputable publications, and entity work so your brand is represented consistently. It says it works in competitive sectors including finance, SaaS, healthcare and B2B, and has a dedicated local search team for regional and multi-location businesses.
What stands out
- Digital PR and authority building as core parts of ChatGPT work
- Published case study of a forex client referenced in LLMs through content and listicles
- Local search team for location-driven businesses
Worth knowing
- Pricing is not published.
- Its ChatGPT page says little about crawler access or training versus live search, so ask how it handles the technical side.
No. 7
7. RGray
- Best for
- Tech and crypto products that want ChatGPT work joined to classic organic growth
- Based in
- Kyiv, Ukraine
RGray is a growth agency for tech companies, and its ChatGPT SEO page says it has supported more than 80 of them. Its service is split into six parts: a ChatGPT SEO audit, strategy consultancy, technical and GEO optimisation, content and positioning, authority development and visibility monitoring. The audit is thorough on paper, measuring brand mentions, citation share, sentiment, source diversity, competitor presence, technical access, positioning accuracy and ChatGPT-referred traffic, and explaining why answers look the way they do.
The authority work builds relevant links, expert mentions, digital PR, directory coverage and partner content that corroborate key facts about you. Its featured case study is a crypto analytics platform built from launch, where AI-referred visits became a measurable acquisition channel.
What stands out
- Audit covers sentiment and positioning accuracy, not only mentions
- Can support an existing SEO or content team rather than replace it
- Monitoring includes referral sessions and assisted conversions
Worth knowing
- No pricing is published, and the first step is a free consultation.
- Its proof and client base lean towards tech and crypto, so other sectors should ask for relevant examples.
How to choose a ChatGPT SEO agency
Start by asking where your buyers meet ChatGPT. A SaaS buyer asking for the best tool in a category is a different problem from a homeowner asking for a plumber near them, and the agencies here split along that line. SearchAxe, Shila and RGray are built around software and tech products, SEOArmy around US service businesses, and Quirky Digital around UK brands in crowded sectors where authority is the bottleneck.
Then test their understanding of ChatGPT itself. A good agency should explain, without notes, the difference between what ChatGPT knows from training and what it finds when it searches, which OpenAI crawler matters for which, and why Bing rankings come into it. Ask to see a prompt report with repeated runs, and ask how ChatGPT referral visits will show up in your analytics. If the answers drift into general AI talk, keep looking.
Finally, look at the commercial shape. Published prices here range from a one-off audit to a fixed 12-week cycle to a monthly programme, and SEO Engico folds ChatGPT work into its SEO retainer. If your site still needs technical or content work for Google, paying for ChatGPT SEO on its own may not be the best first spend.

Frequently asked questions
What is ChatGPT SEO?
ChatGPT SEO is the work of getting your business named, cited and described accurately when people ask ChatGPT for recommendations. It covers crawler access for OpenAI's search crawler, pages written as clear answers, consistent facts across the web, mentions on the sources ChatGPT cites, and tracking a fixed set of buyer prompts over time.
How does ChatGPT decide which businesses to recommend?
It depends on whether ChatGPT searches. Without search, it answers from what the model learned in training, so brands the web describes often and consistently come to mind first. With search on, it reads current web results, and several agencies on this list point out that ChatGPT search draws on Bing's index, so Bing rankings and the pages that answer the question matter.
Does blocking GPTBot remove my site from ChatGPT?
No. OpenAI documents GPTBot as its training crawler and OAI-SearchBot as the crawler used for ChatGPT search, so blocking GPTBot opts your content out of training without removing you from search answers. To appear as a cited source in ChatGPT search, OAI-SearchBot needs access through your robots.txt, CDN and firewall.
How much does a ChatGPT SEO agency cost?
Published prices on this list include SearchAxe at $1,499 a month with a three-month minimum, MV3 Marketing at $997 for an audit then from $2,497 a month, and Shila at $5,000 for a 12-week cycle. SEO Engico includes ChatGPT work in its $4,500 a month SEO retainer. Cost depends on how competitive your category is and how much needs fixing.
How long does ChatGPT SEO take to work?
Answers that come from ChatGPT search can change within weeks of a real fix, because they follow live web results. Answers drawn from training data move more slowly, because they only change when OpenAI releases a newer model. That is why the better agencies track search on and search off separately.
Can you pay to appear in ChatGPT's answers?
Not in the organic answer. There is no paid way to change what ChatGPT recommends on its own. SEOArmy notes that ChatGPT ads now appear as a labelled sponsored placement below the answer, which is separate from the organic recommendation and bought like any other ad.
Our verdict
Pick SEO Engico if you want ChatGPT treated as part of one search programme, with the questions your buyers ask tracked monthly and results reported as calls, enquiries and revenue. Choose SearchAxe or Shila if you are a SaaS startup that wants ChatGPT-specific work at a published price, MV3 Marketing if you want every deliverable itemised, SEOArmy if you run a US service business, RGray for tech and crypto products, and Quirky Digital if you are a UK brand that needs authority built off-site.
