You can check all three in about ten minutes with curl. The steps below go in that order, because each one can make the next irrelevant. ## Which ChatGPT crawler reads your site? OpenAI documents three user agents at [developers.openai.com/api/docs/bots](https://developers.openai.com/api/docs/bots) (read on 31 October 2026), and “can ChatGPT read my site” means different things for each: | User agent | When it reads your page | What it means if it can’t | | --- | --- | --- | | `OAI-SearchBot` | Ahead of time, to build ChatGPT’s search index | You won’t appear in ChatGPT search answers | | `ChatGPT-User` | Live, when someone pastes your URL or ChatGPT browses for them | That person’s request fails in front of them | | `GPTBot` | Ahead of time, for model training | Nothing visible today; training is a separate choice | For being found and cited, OAI-SearchBot and ChatGPT-User are the two that matter. [GPTBot vs OAI-SearchBot vs ChatGPT-User](https://www.blackseoanalyzer.com/en/blog/gptbot-vs-oai-searchbot-vs-chatgpt-user) covers the difference in depth. ## Step 1: What does your robots.txt say? Fetch it and look for groups that name OpenAI’s tokens, plus the `*` group, which applies to any bot without its own group: ```bash curl -s https://example.com/robots.txt ``` Read it the way a crawler does. A bot uses the most specific group that names it and ignores the rest. So this file blocks OAI-SearchBot entirely, even though `*` allows everything: ```text User-agent: * Allow: / User-agent: GPTBot User-agent: OAI-SearchBot Disallow: / ``` That is the most common accident I see: a snippet meant to stop training that also removes the site from ChatGPT search. Paste your file into the free [robots.txt tester](https://www.blackseoanalyzer.com/en/tools/robots-txt-tester) and test a few URLs with `OAI-SearchBot` and `ChatGPT-User` as the user agent. One caveat from OpenAI’s own documentation: for ChatGPT-User, “robots.txt rules may not apply,” because the fetch was started by a person. A `Disallow` there is a request, not a guarantee. ## Step 2: Does your server actually answer them? robots.txt can say yes while your firewall says no. CDNs and bot-management products, Cloudflare among them, have settings for AI crawlers that act before your robots.txt is read, and their defaults have changed more than once. Ask for a page with each user agent and look at the status code: ```bash for ua in "OAI-SearchBot/1.4" "ChatGPT-User/1.0" "GPTBot/1.4"; do code=$(curl -s -o /dev/null -w "%{http_code}" \ -A "Mozilla/5.0 (compatible; $ua; +https://openai.com/bot)" \ https://example.com/your-page) echo "$ua $code" done ``` You want `200`. A `403`, a `503` or a challenge page means something in front of your site is turning the bot away. This test has a blind spot. Spoofing the user agent from your laptop does not come from OpenAI’s IP ranges, so a CDN that verifies bots by IP may treat your test differently from the real crawler. The ground truth is your access log: if real OAI-SearchBot and ChatGPT-User requests are arriving and getting `200`, you are fine. ```bash grep -E 'OAI-SearchBot|ChatGPT-User' access.log | awk '{print $9}' | sort | uniq -c ``` That prints a count per status code. On this site, OAI-SearchBot made 1,159 requests in October 2026 and ChatGPT-User 1,012; if yours shows none at all over a month, the bots are either blocked upstream or have not found you yet. ## Step 3: Is the content in the HTML? OpenAI’s crawlers read the HTML your server returns. If your page is a JavaScript app that builds its content in the browser, the crawler may receive a nearly empty document. Compare what the server sends with what a browser shows: ```bash # words in the raw HTML, tags stripped curl -s -A "Mozilla/5.0 (compatible; OAI-SearchBot/1.4; +https://openai.com/searchbot)" \ https://example.com/your-page | sed -e 's/<[^>]*>//g' | wc -w ``` Now open the same page in a browser, select all the text and paste it into a word counter. If the browser count is several times larger, most of your content arrives by JavaScript, and ChatGPT is probably reading the smaller version. The usual giveaway is a raw response that is little more than `
` and a script tag. [Can AI crawlers see JavaScript content](https://www.blackseoanalyzer.com/en/blog/can-ai-crawlers-see-javascript-content) explains why, and server-side rendering or static generation is the fix. Check the parts that matter most separately: is the main heading in the raw HTML, is the first paragraph there, are the links to your other pages there, and is your structured data there or injected by a tag manager? ## Step 4: Can ChatGPT read it, in practice? Ask it. Paste the URL into ChatGPT and ask for a summary of a specific section, preferably one that only appears lower on the page. If the summary is generic or wrong, ChatGPT-User got less than you think. This is anecdotal, not a test you can automate, but it catches surprises such as a cookie wall or a geo-redirect that only bots hit. ## How do you check every page instead of one? The curl steps work for one URL. For a whole site, bseoa’s AI-readiness checks do the same comparisons on every page it crawls. With JavaScript rendering turned on in the desktop app or CLI, it renders each page in headless Chrome, compares the result with the raw HTML and reports pages where most of the [text requires JavaScript](https://www.blackseoanalyzer.com/en/technical-seo/ai-readiness-analyzer/text-requires-javascript), where [headings](https://www.blackseoanalyzer.com/en/technical-seo/ai-readiness-analyzer/headings-require-javascript), [links](https://www.blackseoanalyzer.com/en/technical-seo/ai-readiness-analyzer/links-require-javascript) or [structured data](https://www.blackseoanalyzer.com/en/technical-seo/ai-readiness-analyzer/structured-data-requires-javascript) only exist after JavaScript runs, and, on every crawl, where the server sends an [empty app shell](https://www.blackseoanalyzer.com/en/technical-seo/ai-readiness-analyzer/empty-app-shell-served-to-crawlers). It also reads your robots.txt and reports a [blocked AI search crawler](https://www.blackseoanalyzer.com/en/technical-seo/ai-readiness-analyzer/ai-search-crawler-blocked) or a [blocked user-initiated fetcher](https://www.blackseoanalyzer.com/en/technical-seo/ai-readiness-analyzer/ai-user-action-crawler-blocked). The [14-day trial](https://www.blackseoanalyzer.com/en/free-trial) runs every check with no page limit. It cannot see your CDN’s bot rules; only your access log shows those. ## Is being readable enough? No. Readable is the entry ticket. Whether ChatGPT quotes you depends on whether your page answers the question better than the other pages it read, which is mostly classic SEO and clear writing.
