How to Make Your Business Visible in ChatGPT, Gemini, Perplexity and Copilot
ChatGPT, Gemini, Perplexity and Copilot each surface businesses through different mechanisms. This guide sets out the documented differences and the practical checklist that applies across all four.
In short
There is no single technique that works identically across ChatGPT, Gemini, Perplexity and Copilot, because each draws on a different underlying search or crawling mechanism. The practical approach is the same throughout: keep the site crawlable by each platform's named bots, state facts about the business clearly and consistently, and be indexed by the search engine each platform depends on (Google for Gemini, Bing for Copilot). No one can guarantee a mention on any of them.
A buyer today might ask ChatGPT who supplies something, check Gemini for a second opinion inside Google Search, ask Perplexity for a comparison, or have Copilot surface an answer inside Microsoft 365. Each of these systems works differently underneath, and a business that wants to be found by more than one of them needs to understand the genuine, documented differences — not treat them as a single undefined thing called 'AI search'.
This guide sets out what each platform actually documents about how it finds and uses web content, then gives one practical checklist that applies across all of them. For how AI systems generally decide which businesses to mention, see our companion article on how AI systems decide which companies to recommend.
Why these platforms are not interchangeable
'Appearing in AI search' is often discussed as one problem. It isn't. ChatGPT, Gemini, Perplexity and Copilot are built by different companies, use different crawlers, and in several cases depend on an entirely separate search engine underneath. A business can be well set up for one and invisible to another, because the mechanics genuinely differ — not because of some unified 'AI SEO' score.
ChatGPT
OpenAI documents three separate crawlers with different jobs: GPTbot, used for model training; OAI-SearchBot, used to find and surface pages in ChatGPT's search feature; and ChatGPT-User, used when ChatGPT fetches a page a user has referenced or asked about. These are controlled independently through robots.txt. OpenAI states that a site which opts out of OAI-SearchBot will not appear in ChatGPT's search results, though it may still appear as a plain navigational link in some contexts.
- FACT: GPTBot, OAI-SearchBot and ChatGPT-User are documented, separately controllable crawlers (platform.openai.com/docs/bots)
- FACT: blocking OAI-SearchBot removes a site from ChatGPT's search answers
- UNKNOWN: the exact ranking or selection logic ChatGPT's search feature uses among crawled pages is not published
Gemini and Google AI Overviews / AI Mode
Google documents that there are no special requirements beyond normal Search eligibility to appear in AI Overviews or AI Mode: a page needs to be indexed by Google Search and eligible to be shown as a normal result or snippet. There is no separate 'AI index' to optimise for — the same technical and content fundamentals that support ranking in ordinary Google Search apply. Google-Extended is a distinct robots.txt token that controls whether content can be used to improve Gemini's underlying models and grounding; Google states this does not affect inclusion or ranking in Google Search itself.
- FACT: no documented extra optimisation exists for AI Overviews/AI Mode beyond standard Search eligibility (Google Search Central, 'AI features and your website')
- FACT: Google-Extended controls Gemini training/grounding use, separately from Search indexing
- OBSERVATION: Search Console does not separate AI Overview impressions from normal Search performance; both sit in the same Performance report
Perplexity
Perplexity documents two crawlers: PerplexityBot, used for indexing content for its search answers, and Perplexity-User, used for on-demand fetches triggered by a user's question. As with OpenAI's crawlers, these are independently controllable through robots.txt. Perplexity's selection and ranking logic for which indexed pages it cites is not publicly documented.
Microsoft Copilot
Microsoft documents that Copilot grounds its web-based answers using Bing search results. This means Bing indexing is a precondition for Copilot visibility in the same way Google indexing matters for Gemini: a page Bing has not indexed is very unlikely to be surfaced by Copilot. Bing Webmaster Tools and IndexNow (a protocol Bing supports for faster index submission) are the practical tools available; the detail of how Copilot selects and weights sources from Bing's index is not public.
One practical checklist across all four
- 01Check robots.txt does not block GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, Google-Extended, Googlebot or Bingbot unless there is a deliberate reason to
- 02Confirm the site is indexed in both Google Search Console and Bing Webmaster Tools — two separate tools, two separate checks
- 03Make sure what the company does, for whom and where is stated in plain, consistent language, not only inferable from design or logos
- 04Serve key facts in server-rendered HTML rather than relying solely on client-side JavaScript, since not all crawlers execute it reliably
- 05Add structured data (Organisation, Service, LocalBusiness where genuine) so facts are machine-readable, not just human-readable
- 06Maintain consistent facts across the website and third-party sources — directories, reviews, press — that these systems may also draw on
Can you pay to appear in ChatGPT, Gemini, Perplexity or Copilot answers?
Not in the organic answer itself. None of these platforms documents a mechanism to pay for inclusion in an organic AI-generated answer. Advertising products on these platforms, where they exist, are separate and clearly labelled, and this changes over time — check each platform's current official policy rather than relying on this or any other article for the latest position.
Can visibility be guaranteed?
No. None of these platforms sells placement in organic answers, publishes its full selection logic, or offers an appeals process if a business is not mentioned. Evans Sales Consultancy, like any credible consultancy, cannot guarantee a ChatGPT, Gemini, Perplexity or Copilot mention. What can be controlled is removing the practical reasons a business would be overlooked: crawlability, clarity and consistency.
Why might ChatGPT mention a company but not recommend it?
A mention and a recommendation are different outcomes. A system may cite a company factually ('X also offers this service') while a direct recommendation ('you should use X') depends on the system judging the company to be a strong, well-corroborated answer to the specific question asked. This is consistent with how retrieval-based answers are understood to work, though the exact distinction is not something any provider documents in detail. Thin or generic content tends to produce mentions at best; specific, well-corroborated content is more consistent with being recommended — this is an inference, not a guaranteed mechanism.
How long does this take?
There is no published timeline from any platform. What can be said is sequential: a page must first be crawled, then indexed (by Google or Bing, where relevant), before it can plausibly be retrieved by an AI answer. Each of those steps can take anywhere from days to months depending on the site's existing crawl history and authority. Measuring progress against indexing and, where tools allow, citation tracking is more useful than expecting a fixed number of weeks.
Measuring progress, not guessing
Keep the measurement levels distinct: being indexed is not the same as ranking, ranking is not the same as being cited in an AI answer, and a citation is not the same as an enquiry. Search Console and Bing Webmaster Tools confirm indexing and ranking. Confirming AI citation generally means manually testing representative buyer questions across platforms, since none of the four provides a reliable, comprehensive citation report today.
Want to know which buyer questions you are found for — and where you are missing?
Search & AI Visibility monitors how your business appears in Google and AI answers for the questions your buyers ask, and what to fix first. No guaranteed rankings — just honest measurement and prioritised work.
