Why ChatGPT is different
It sends most AI referrals. OpenAI says ChatGPT has more than 1 billion weekly active users. In September 2026 it sent 80.5% of AI chatbot referrals to websites worldwide, against 10.9% for Gemini, 5.9% for Perplexity, 1.8% for Copilot and under 1% for Claude (StatCounter). In Southeast Asia its share runs from 68% in Vietnam to 85% in Indonesia.
Three OpenAI bots do three different jobs. OAI-SearchBot decides whether your pages can appear in ChatGPT's search answers: block it in robots.txt and you won't be shown, apart from bare navigational links. GPTBot collects content that may be used to train OpenAI's models, so blocking it opts you out of training, not search. ChatGPT-User fetches a page when someone asks ChatGPT to, and OpenAI says robots.txt may not apply to it. A robots.txt change takes about 24 hours to reach OpenAI's systems.
It cites a different web from Google. In Profound's analysis of 680 million citations from August 2024 to June 2025, Wikipedia was ChatGPT's most-cited source: 7.8% of all its citations, and 47.9% of the citations that went to its ten most-cited sites. Reddit, Forbes, G2, TechRadar and NerdWallet came next, while Reddit led for Google's AI Overviews and Perplexity. So whether ChatGPT names you depends as much on reference sites, review sites and the press as on your own pages.
Its clicks are labeled. ChatGPT adds utm_source=chatgpt.com to the links it sends, as long as OAI-SearchBot can reach your pages. Since 13 May 2026, GA4 has had an AI Assistant channel that groups visits from ChatGPT, Gemini, Copilot and others, while Google's own AI Overviews and AI Mode still count as Organic Search. So you can see the visits, and the leads, that ChatGPT sends you.
Shopping and ads now sit inside it. Merchants can send OpenAI a product feed so ChatGPT can show their products, OpenAI documents a checkout inside ChatGPT, and businesses can publish plugins in a ChatGPT Directory. Ads began as a US test in February 2026, for adults on ChatGPT's no-cost tier and its low-cost Go plan, and OpenAI now sells them in more than 40 countries. It says ads are always labeled, kept separate from answers and don't influence them. You can buy a spot beside the answer; a place in it still has to be earned.
How we chose
Every AI search optimization agency on this list passed five tests:
- A ChatGPT-specific service. A dedicated ChatGPT optimization page on the agency's own site, or a GEO service page that spells out its ChatGPT work.
- Work on the sources ChatGPT reads. Pages built to be quoted, plus digital PR, mentions or citations on the third-party sites AI draws on.
- A way to measure it. Prompt testing, citation tracking, ChatGPT referral reporting or its own tracking tools.
- Evidence. Named clients, reported results, published research or published prices.
- A distinct fit. Each agency suits a different kind of business, budget or market.
Every fact about the other nine agencies comes from their own websites, checked on 13 October 2026. Results and claims are their own.
1. GTMLab
Best for: businesses in Southeast Asia and Hong Kong that want to be named when buyers ask ChatGPT, and to see the enquiries it sends.
GTMLab is a growth agency with teams in Jakarta, Hong Kong and New York, run by 100+ senior operators that include ex-founders, Y Combinator alumni and a Forbes 30 Under 30 honoree. It has worked with 200+ brands, including IHH Healthcare, Lazada, ELSA Speak and Lion Parcel, and operated $20M+ in ad spend.
Its AI search optimization service runs on daily decisions rather than a fixed content quota. Each day the team checks what changed for a client's buyer prompts, such as "best B2B logistics company in Indonesia" in ChatGPT, picks the few tasks that drive most of the result, does them wherever AI engines read about the brand that week, and logs each one with the reason behind it. It tracks six engines: ChatGPT, Gemini, Perplexity, Google's AI Overviews, Claude and Copilot.
What sets it apart
- Built for markets where ChatGPT leads: ChatGPT sends 68% to 85% of AI chatbot referrals across Southeast Asia's six largest markets, and GTMLab works in English and Bahasa Indonesia.
- ChatGPT leads you can count: AI referrals are tracked as their own source in GA4 on every plan, and in your CRM on Growth and Scale, so an enquiry from ChatGPT can be followed to a booked call or a sale.
- Progress you can see: a dashboard of where you're named, who's named instead and progress to target, plus a daily task log with win alerts and a call every two weeks.
- One team from answer to follow-up: the same operators run paid media, SEO, landing pages, WhatsApp follow-up and the CRM.
Proof: GTMLab built and runs search for medifly.ai, a medical travel platform for Indonesian patients, giving each of its 3,167 doctors and 299 hospitals a complete page in Bahasa Indonesia and English, with structured data and a robots.txt open to AI crawlers. Between mid-June and late September 2026, organic clicks grew about 4× and impressions about 5.6×. The case study is candid that there's no AI-citation data yet, so this is the search groundwork AI answers draw on.
Pricing and guarantee: Essential at $499 a month (30 logged tasks, 40 prompts tracked across 3 AI engines, re-run weekly), Growth at $999 (70 tasks, 90 prompts, 4 engines, CRM tracking) and Scale at $1,999 (140 tasks, 150 prompts, 5 engines, re-run daily). Plans start on a six-month term, then run month to month; in Jakarta they start from IDR 9 million a month. GTMLab guarantees a number of prompts where you're named every quarter; miss it and you don't pay.

What a ChatGPT visibility plan should cover
Whichever generative engine optimization agency you hire, the work should include:
- An open door for OAI-SearchBot. Check that robots.txt allows it and that a firewall or CDN isn't blocking it; OpenAI publishes its crawlers' IP ranges for this. Blocking GPTBot, if you want to opt out of training, won't affect search.
- A prompt list, tested often. List the 30 to 50 questions buyers ask before choosing a business like yours, run them in ChatGPT with search on, and record who's named, what's said about you and which pages are cited. Answers change, so re-run them every week or two.
- Work on the sources it cites. If ChatGPT keeps citing a directory, a review site, a listicle or a Wikipedia page for your category, that's where the work is: get listed accurately, earn reviews and fix facts that are out of date. Keep your name, services, prices and locations the same everywhere.
- Pages worth quoting. One complete page for each product, service and location, with a direct answer near the top, plain facts and structured data. If you sell products, send ChatGPT a product feed.
- Tracking from click to customer. Watch GA4's AI Assistant channel and filter for
utm_source=chatgpt.com, add "ChatGPT or another AI assistant" to "How did you hear about us?", and save each lead's first source in your CRM to see which ChatGPT visitors became customers. - Ads as a separate test. ChatGPT ads put you beside the answer, not in it. If you run them, allow OAI-AdsBot, which OpenAI uses to check ad landing pages.

An agency that knows ChatGPT will talk about those sources, not just your website.

Frequently asked questions
What does an agency for ChatGPT visibility do?
It works to get your business named, and described accurately, when people ask ChatGPT about your category. That means making sure OpenAI's search crawler can read your site, building pages ChatGPT can quote, earning mentions on the sites it cites, testing your buyers' prompts and tracking the visits ChatGPT sends. A good GEO agency covers the other AI engines too.
How does ChatGPT decide which businesses to name?
No one outside OpenAI knows the full method, but three things are clear. Its search answers can only include pages its OAI-SearchBot crawler is allowed to read. Citation studies show it leans on Wikipedia, publications and review sites such as G2. And ads can't buy a place in the answer: OpenAI keeps them labeled and separate, and says they don't influence what ChatGPT says.
How much does ChatGPT optimization cost?
On this list, published prices start at $499 a month (GTMLab's Essential plan). Embarque starts at $1,500 a month, MADX Digital at $2,500, Tenet charges $2,500 to $10,000, and WebFX starts at $3,000. Found, Go Fish Digital, The SEO Works, Hallam and Techmagnate don't publish prices.
Can you track the leads ChatGPT sends?
Yes, for visitors who click through. ChatGPT tags its links with utm_source=chatgpt.com, and GA4's AI Assistant channel, added in May 2026, groups those visits automatically. An AI option in "How did you hear about us?" catches buyers who read an answer and came back another way.
Should you block GPTBot?
That's a decision about training, not visibility. Blocking GPTBot tells OpenAI not to use your content to train its models, while blocking OAI-SearchBot is what keeps you out of ChatGPT's search answers. OpenAI treats each setting separately, so you can allow OAI-SearchBot and block GPTBot; changes take about 24 hours to apply.
Can you pay to appear in ChatGPT?
You can buy ads, but not a place in the answer. OpenAI began testing ads in the US in February 2026 and now sells them in more than 40 countries. They're labeled and kept separate from answers, and OpenAI says advertising doesn't influence them, so being named still takes organic work.
See where you stand first
Before you speak to any GEO marketing agency, see what AI says about your business today. GTMLab's AI visibility check asks ChatGPT, Gemini, Perplexity, Google's AI Overviews and Claude what a customer in your city would ask, then shows who they name instead of you, where they got their facts, what to fix first, and how fast your site loads on a phone. It takes about a minute, with no sign-up for the first read. Plans are on the pricing page.
