AI crawler
An AI crawler is a program that automatically fetches information for AI systems. It can crawl websites in bulk or read a specific page on a user’s request; different bots serve search, training or live answers.
Why the type of bot matters
A bot may collect data to train a model, feed a search index or read a page during a specific conversation. Blocking one kind of access doesn’t have to block the others.
What an access audit tells you
Heuriso checks technical signals such as robots.txt rules and server responses. They help you spot potential obstacles.
A test request using a bot’s name isn’t the same as a confirmed visit from that bot’s real servers. Nor does it replace data on whether a page was actually fetched or cited.
Why access should be checked page by page
Your homepage may work fine while a product page requires a login, returns an error or shows important content only after extra interaction. Checking one page doesn’t confirm access to the whole site. Start with the URLs that hold the most important information for customers: services, pricing, documentation and support policies. Watch for redirects and server-level protection as well.
If you have access to server logs, they can show which requests reach your server and what responses they get. The text identifying a bot can be spoofed, so verifying where it came from requires the methods the operator documents. Distinguish a genuinely logged visit from an access test run by an audit tool.
Your own test request can help catch an error, but it doesn’t show the whole path an external system takes to process your content. Even after a successful test, you still need to check separately whether the material was discovered, understood and used. None of these steps follows automatically from the previous one.
Common mistake: assuming that unblocking means being recommended
Allowing a crawler makes fetching possible, but it doesn’t guarantee your content will be used in an answer. The system may consider another source more relevant. Don’t remove every protection just to turn a technical check green. First establish what each restriction is for, which kind of bot it affects and which public content you actually want to make available.
Example
A website can allow a search crawler while limiting the collection of data for model training. These two decisions don’t contradict each other.
Key takeaway
Check what each bot is for. Access to your site is a technical prerequisite, not a promise that AI will cite it.
