If you want to know how to get indexed by ChatGPT, I’ll show you, but first, I want to clarify: Other articles on this topic conflate “getting indexed by” with “showing up in” ChatGPT — and they are not the same thing. Getting indexed by ChatGPT means OpenAI’s search crawler discovered your page and stored it in OpenAI’s proprietary index (about which very little is publicly known). Showing up in ChatGPT means your content appeared in an answer, which can happen via that index or via a live web fetch triggered by a user’s query. In this guide, I’ll explain both concepts so you understand them, then show you how to get your website indexed by ChatGPT by ensuring OpenAI’s search crawler can discover your site. The ultimate goal of getting indexed is to eventually get cited and mentioned in the LLM's answers to enhance your answer engine optimization (AEO) efforts. If it sounds complicated, don’t worry. I’ll make it easy for marketers to understand and implement. Getting indexed by ChatGPT means that, not only was your webpage crawled by OpenAI’s crawlers (primarily OAI-SearchBot), but at least some of what the bot discovered was then stored for later potential retrieval, making it possible that the same content could surface in future answers generated by ChatGPT. When a user submits a prompt in ChatGPT, the model forms an answer using a combination of the following: Note: Beyond the offline web search feature documented for eligible workspaces, SEO/AEO practitioners have reported evidence of broader cached-index behavior in ChatGPT through independent experiments (which I’ll describe in a section below). This broader behavior has not been officially confirmed by OpenAI. See exactly where your brand shows up in answer engines and take action to close AI visibility gaps. Because OpenAI doesn’t publish details about the architecture or mechanics of its index, no one writing about it right now truly knows its inner workings. But the whole “index” framing is based on what we do know about Google’s search index. Google has crawlers, such as Googlebot, that crawl the web to obtain content to store in Google’s index, which the search engine pulls from to serve results on its SERPs. From that framework, we can deduce that there are three steps of OpenAI’s indexing: Unlike Google, which has 20+ publicly documented crawlers and potentially hundreds of non-public ones, as of May 2026, OpenAI has four publicly documented crawlers and user agents: For marketers trying to get indexed by ChatGPT, OAI-SearchBot is the crawler that likely matters most. GPTBot affects training, not ChatGPT search visibility. As of April 2026, OpenAI’s help center confirmed the existence of its web index by publishing that eligible workspace accounts can enable offline web search, which uses “OpenAI’s indexed and cached web content.” I posted about this on LinkedIn and got interesting comments from SEO and marketing professionals who say they’ve seen caching/indexing behavior from OpenAI even before the company published about it. Further, during the Google antitrust remedies trial in April 2025, court filings show that OpenAI’s Nick Turley testified that his company is building its own search index. Additionally, independent SEO/AEO experts have been running experiments that support the existence of a cached/indexed layer used by OpenAI’s web search tooling. Technical SEO Jérôme Salomon surfaced the external_web_access parameter on OpenAI’s Responses API web_search tool, using Google Colab to compare answers with external_web_access: false (cache-only) against live web access. James Berry of LLMrefs then ran dozens of follow-up tests using the same parameter and documented behavioral findings about the cached index, including how quickly it refreshes for trending stories and that pages remained accessible in cache-only mode more than 30 days after indexing. Berry’s tests also suggest ChatGPT-User contributes to the cached index alongside OAI-SearchBot — though OpenAI’s documentation explicitly says ChatGPT-User is not used to determine search appearance. Pro tip: The existence of offline web search means that those with eligible ChatGPT workspaces now have a non-technical way to check if their content is in OpenAI’s index, as my colleague Victor Pan so brilliantly pointed out. Simply prompt ChatGPT with a URL while offline web search is enabled; if it returns your content, that’s a strong signal the page is in OpenAI’s index or cache. I’d be remiss to write this section without a caveat: Getting indexed by ChatGPT is not something marketers can directly submit for or verify the way they can with Google Search Console. As I mentioned before, OpenAI hasn’t publicly disclosed the inner workings of its index. Additionally, OpenAI publishes very little on how to get surfaced in ChatGPT’s answers. Contrast that with the loads of documentation that Google publishes in its Google Search Central, and ChatGPT feels like a black box. So, given what little official documentation we have, the best marketers can do is make content eligible for discovery, retrieval, and citation, and lean on independent experiments to infer what helps pages get indexed by ChatGPT. I’ll walk you through what I’ve found below.
