Get Indexed in ChatGPT, Perplexity and Copilot: What AI Search Actually Reads
Every week brings another tool promising to submit your site to ChatGPT. There is nothing to submit to. ChatGPT, Perplexity, Copilot and Google AI Overviews do not maintain a public index you can push a URL into, and no vendor has a back door to one. What they do is retrieve pages at question time from a search index, then write an answer over the top of what they retrieved and link the sources.

In short
You cannot submit a URL to ChatGPT, Perplexity or Copilot, because none of them runs a public submission endpoint and none of them indexes the web the way Google does. AI answers are assembled by retrieving pages from a search index at the moment of the question, so the two things you control are whether your pages are in those indexes and whether the AI crawlers are allowed to fetch them. Google states the requirement plainly for its own AI features: to be shown as a supporting link in AI Overviews or AI Mode, a page must be indexed and eligible to be shown in Google Search with a snippet. OpenAI says ChatGPT search leverages third-party search providers along with content from its partners, and it documents OAI-SearchBot as the crawler behind search surfacing, noting that sites opted out of OAI-SearchBot will not be shown in ChatGPT search answers. So the work is not a new channel. It is index coverage in Google and Bing, an open robots.txt for the AI crawlers, and content structured so a model can lift a clean answer out of it.
Last updated July 2026
That sounds like bad news and it is the opposite. It means the lever is the one you already have. If a page is indexed, snippet-eligible and reachable by the right crawler, it is in the pool an AI answer can draw from. If it is not indexed, no amount of structure, schema or llms.txt puts it there. Google says this outright in its own documentation for AI features, and it is the single most useful sentence published on the subject.
This page sets out what each major AI engine actually reads, the exact crawler user agents involved and what each one controls, the two settings that quietly remove a site from AI answers altogether, and how to check the whole thing rather than guess. Run your URLs through the console above first: Indexing reports which pages Google and Bing currently hold, names the reason for every gap in plain English, and submits the ones that belong there through official channels only. Index coverage is the floor everything else in AI search is built on.

Why it works
What your team gets with chatgpt and ai search indexing
Indexing is the eligibility gate
Google documents it directly: a page must be indexed and snippet-eligible to be shown as a supporting link in AI Overviews or AI Mode. Everything else is downstream of that.
Crawler access is separate
OpenAI, Anthropic and Perplexity run their own user agents. Blocking OAI-SearchBot removes you from ChatGPT search answers even when your pages are perfectly indexed.
Nobody sells a submission
There is no AI submission API and no paid placement in AI citations. Any tool charging to submit your URL to ChatGPT is selling you something that does not exist.
What it handles
Submitted, monitored and fixed, automatically
Indexing submits your URLs through the official Google Indexing API, Bing IndexNow and clean XML sitemaps, watches coverage across both engines, and flags any page that drops out with a plain-English reason so you can resubmit and get it back.
- Reports Google and Bing index status separately, because AI retrieval draws on both
- Names the reason a page is not indexed, which is the reason it cannot be cited
- Submits new and changed URLs through IndexNow, which Bing acts on within minutes
- Flags pages that are crawled but not indexed, the most common silent AI visibility gap
- Watches for pages dropping out of the index, so a citation source does not vanish quietly
- Uses documented APIs only, never link pings, PBNs or fake AI submission endpoints

Why Indexing
One place to submit, monitor and fix coverage
Not a black-hat indexer that risks your site, not a free checker that only tells you the bad news. Indexing unifies official submission and live coverage monitoring, the white-hat way, across Google and Bing.
Submits the official way
Bulk-submit through the Google Indexing API, Bing IndexNow and clean XML sitemaps. We speed discovery and re-crawl using methods the engines support, never spam, PBNs or black-hat tricks.
Monitors coverage live
You do not refresh a search bar one URL at a time. Indexing watches which pages are in Google and Bing, catches anything that drops out, and tracks time-to-index across your whole site.
Diagnoses and resubmits
Every non-indexed page comes with a plain-English reason, then auto-resubmits through the official API so it gets another shot. Google still decides, but nothing waits in the dark.
At a glance
What each AI engine reads, and what you actually control
Crawler tokens below are taken from each operator's own published documentation. Where an operator does not disclose which search index it retrieves from, this table says so rather than guessing.
| AI engine | How it finds pages | Crawler user agent | Submission endpoint? | What you control |
|---|---|---|---|---|
| ChatGPT search | OpenAI says it leverages third-party search providers plus partner content. It does not name the providers. | OAI-SearchBot for search surfacing, ChatGPT-User for live fetches | None exists | Index coverage in the major engines, and allowing OAI-SearchBot |
| Google AI Overviews and AI Mode | Google Search index. Supporting links come from pages already eligible in Search. | Googlebot, with Google-Extended governing AI use outside Search | None beyond normal Search submission | Being indexed and snippet-eligible. Google says nothing else is required. |
| Microsoft Copilot | Bing index and AI summaries in Bing. Bing Webmaster Tools now reports citations directly. | Bingbot | IndexNow, which Bing acts on | Bing index coverage, verified in Bing Webmaster Tools |
| Perplexity | Its own crawl plus retrieval at question time. | PerplexityBot for indexing, Perplexity-User for user-triggered fetches | None exists | Crawler access and page structure. Perplexity-User is documented as generally ignoring robots.txt. |
| Claude | Web search at question time, not a standing public index you submit to. | ClaudeBot, Claude-SearchBot, Claude-User | None exists | Crawler access and a page a model can quote cleanly |
How do I get indexed in ChatGPT?
By being indexed in ordinary search and letting OpenAI fetch the page. That is the whole mechanism, and it is worth being blunt about it because a small industry has grown up implying otherwise. OpenAI does not run a webmaster console, there is no URL submission form, and there is no partner program that gets a normal business cited. ChatGPT search, in OpenAI's own description, leverages third-party search providers as well as content provided directly by its partners.
OpenAI does publish the crawler side in detail, and this is the part site owners get wrong. Four user agents matter and they do different jobs. OAI-SearchBot handles search surfacing, and OpenAI states that sites opted out of OAI-SearchBot will not be shown in ChatGPT search answers. GPTBot is for training generative models, which is a separate decision with no bearing on whether you get cited. ChatGPT-User performs live fetches when a user action triggers them, and OpenAI notes that because those actions are user-initiated, robots.txt rules may not apply. OAI-AdsBot handles ad safety validation.
The practical consequence catches a lot of teams. Somebody reads a headline about AI scraping, adds a blanket block for every OpenAI agent, and quietly removes the site from ChatGPT search answers along with the training corpus. Those are different choices. If you want to stay out of training but remain citable, disallow GPTBot and leave OAI-SearchBot alone. Check what your robots.txt actually says before you assume it says what you meant.
- There is no ChatGPT submission endpoint. No tool has one either.
- OAI-SearchBot governs search surfacing. Blocking it removes you from ChatGPT search answers.
- GPTBot governs training only. Blocking it does not affect citation.
- ChatGPT-User handles user-triggered fetches, where robots.txt may not apply.
- Get indexed first. An unindexed page has nothing to be retrieved from.
Does ChatGPT index my website?
Not in the sense that Google does. Google maintains a standing index of the web that it crawls continuously and serves results from. ChatGPT assembles an answer at the moment you ask, retrieving pages then rather than reading from an index of its own that you can inspect or submit to. That difference explains most of the confusion in this topic, including why your page can be quoted in one conversation and absent from the next.
It also explains why the usual SEO diagnostics do not translate. There is no coverage report for ChatGPT, no equivalent of the URL Inspection API, and no way to ask whether a specific URL is eligible. The closest thing anyone publishes is on the Microsoft side: Bing Webmaster Tools introduced an AI Performance report in public preview on February 10, 2026, covering how content appears across Microsoft Copilot, AI-generated summaries in Bing and select partner integrations. It reports citation counts, unique pages cited per day, the grounding queries used to retrieve your content, and per-URL citation activity.
That report is the only first-party citation data of its kind currently available, which makes verifying your site in Bing Webmaster Tools a genuinely high-value hour of work in 2026 regardless of what you think of Bing traffic. It will not tell you about ChatGPT specifically, and it would be dishonest to claim otherwise, but it is real measurement in a field otherwise dominated by inference.
- ChatGPT retrieves at question time rather than serving from a public index you can submit to.
- The same page can be cited in one answer and missing from the next.
- No coverage report or inspection API exists for ChatGPT.
- Bing Webmaster Tools AI Performance, public preview February 10, 2026, is the only first-party citation report.
- It covers Copilot, Bing AI summaries and select partner integrations, not ChatGPT by name.
How do I get my site indexed in ChatGPT search?
Work the three layers in order, because they gate each other. Layer one is index coverage. Confirm your pages are actually in Google and Bing, not merely submitted, and fix the ones that are not. This is where most sites lose before they start: a section that sits at Crawled currently not indexed is invisible to every retrieval system downstream, and no amount of AI-specific optimization changes that.
Layer two is crawler access. Read your live robots.txt and confirm OAI-SearchBot, PerplexityBot and ClaudeBot are not disallowed, then check the layer most teams forget, which is the edge. A bot-fighting rule at Cloudflare or a WAF challenge can block AI crawlers while robots.txt sits wide open, and the symptom is silence rather than an error you would notice. Fetch your own pages with those user agent strings and see what comes back.
Layer three is the page itself. Retrieval systems lift passages, so a page that answers a question in a clean self-contained paragraph gets quoted and a page that buries the answer in paragraph nine does not. Lead each section with a direct answer of roughly 40 to 60 words, phrase headings the way people actually ask, put comparable facts in real tables, name the entities involved instead of writing this tool, and show an honest last-updated date. None of that is exotic and all of it also helps ordinary search.
- Layer one: confirm the pages are indexed in Google and Bing, not just submitted.
- Layer two: allow OAI-SearchBot, PerplexityBot and ClaudeBot in robots.txt.
- Check the CDN and WAF too. Edge blocks are invisible in robots.txt.
- Layer three: answer-first paragraphs of 40 to 60 words under question-shaped headings.
- Use real tables. Retrieval extracts structured comparisons far more reliably than prose.
- Show an accurate last-updated date. Stale pages lose to fresh ones in AI answers.
Do I need an llms.txt file to appear in AI search?
No, and the evidence on this is unusually clear. Google's documentation on AI features states that you do not need to create new machine readable files, AI text files or markup to appear in AI Overviews or AI Mode, and that there is no special schema.org structured data required either. No Google Search system reads llms.txt. No major AI engine has committed to reading it as a ranking or retrieval input.
The file itself is a real proposal, published by Jeremy Howard on September 3, 2024, at llmstxt.org, and it has one genuine use case: agentic retrieval, where a model or agent is pointed at your documentation and benefits from a curated map of it. Anthropic and Perplexity both publish one for their own developer docs for exactly that reason. If you run documentation an agent might be sent to read, it is worth twenty minutes. If you are hoping it makes ChatGPT cite your pricing page, it will not.
Spend the same twenty minutes on index coverage instead. A page that is not in a search index cannot be retrieved by anything, whereas a page that is indexed, allowed and clearly written can be cited without a single AI-specific file present. That ordering holds for every engine covered on this page.
- Google states no AI text files or special markup are needed for AI Overviews or AI Mode.
- llms.txt was proposed September 3, 2024, at llmstxt.org. Only an H1 with the project name is required.
- llms-full.txt is a community convention, not part of the spec.
- Real use case: agentic retrieval over documentation. Anthropic and Perplexity publish one.
- It is not a substitute for being indexed, and no engine treats it as a ranking input.
Why Bing index coverage matters more than it used to
For a decade the honest advice on Bing was that it was a rounding error for most US businesses. That calculus changed, and not because Bing search traffic grew. It changed because Bing built the index that Microsoft Copilot answers from, and Microsoft now reports those citations back to you. If your pages are missing from Bing, they are missing from the pool Copilot draws on, and you will not see that in any Google report.
The mechanics are refreshingly simple compared with the Google side. Verify the site in Bing Webmaster Tools, submit the sitemap, and turn on IndexNow so changes are pushed instead of waited for. IndexNow accepts up to 10,000 URLs per request and reaches Bing, Yandex, Seznam and Naver, and Bing commonly crawls submitted URLs within minutes. It costs nothing and needs no OAuth, just a key file at your domain root.
What it does not do is reach Google. Google tested IndexNow starting in 2021 and as of July 2026 still does not use it, so an IndexNow ping tells you nothing about Google coverage. Track the two indexes separately. A tool that averages them into a single coverage percentage is hiding exactly the gap you need to see, which is why the console on this page reports Google and Bing as two numbers.
- Bing index coverage feeds Copilot answers and Bing AI summaries.
- Bing Webmaster Tools is the only place publishing first-party AI citation data.
- IndexNow: key file at your root, up to 10,000 URLs per request, no OAuth.
- It reaches Bing, Yandex, Seznam and Naver, usually crawling within minutes.
- Google tested IndexNow and does not use it as of July 2026.
- Report Google and Bing separately. A blended percentage hides the gap.
The two settings that quietly remove you from AI answers
The first is a robots.txt block written more broadly than intended. Blanket rules against AI crawlers spread quickly through templates and boilerplate in 2024 and 2025, and plenty of sites are still running one that a previous developer added without recording why. The specific mistake that costs citations is disallowing OAI-SearchBot, since OpenAI states that opted-out sites will not be shown in ChatGPT search answers. Blocking GPTBot alone keeps you out of training while leaving search surfacing intact, which is what most owners actually want.
The second is nosnippet, and it catches people out because it looks harmless. Google requires a page to be snippet-eligible to appear as a supporting link in AI Overviews or AI Mode, so a nosnippet directive, a restrictive max-snippet value or a data-nosnippet wrapper around your main content removes the page from those features while leaving it indexed and ranking normally in blue links. Nothing in Search Console flags this as a problem, because from Google's point of view you asked for it.
Both are worth auditing on a schedule rather than once, because both get reintroduced by well-meaning changes. A security team adds a bot rule. A developer adds data-nosnippet to stop a competitor scraping prices. Six months later nobody remembers, and the only symptom is an absence you were never going to notice on your own.
- Disallowing OAI-SearchBot removes you from ChatGPT search answers.
- Disallowing GPTBot affects training only, not citation.
- nosnippet, restrictive max-snippet and data-nosnippet block AI Overviews eligibility.
- Those pages still rank normally in blue links, so the loss is invisible.
- Edge rules at a CDN or WAF can block AI crawlers with robots.txt wide open.
- Re-audit periodically. These settings get reintroduced by unrelated changes.
