This page is designed to help you find out whether AI Crawler Checker is good and if it is the right choice for you.
AI Crawler Checker instantly tells you whether your robots.txt allows or blocks the crawlers that decide if ChatGPT, Claude, Perplexity, and Google AI Overviews can cite your content.
Most sites get this wrong: every major AI vendor runs two different crawlers, and they do different jobs. A training crawler (GPTBot, ClaudeBot) only collects data for future model training — blocking it has zero effect on citations. A retrieval crawler (OAI-SearchBot, ChatGPT-User, Claude-SearchBot, PerplexityBot) fetches your page live while answering a real question, and it's the one that actually decides whether you get cited. Sites routinely block the wrong one, or trip over the "User-agent: *" rule that silently doesn't apply to crawlers with their own named group.
Enter any domain and get an instant breakdown of every AI and search bot's access status, explained in plain terms — plus the specific fix if something's blocked. It's free, takes seconds, and is the first checkpoint in a full GEO (Generative Engine Optimization) audit from the SearchVitals SEO & AI-visibility toolkit.

Free to Use
The tool appears to be offered as a free resource, making it accessible to website owners, SEO professionals, and developers who want to check AI crawler access without any cost barrier.
Quick AI Bot Visibility Check
It allows users to quickly determine whether major AI crawlers (such as GPTBot, ClaudeBot, Google-Extended, and others) are permitted or blocked from accessing their website, which is increasingly important as AI-driven search and content tools grow in prominence.
Useful for AI SEO Strategy
As AI-powered search engines and answer engines become more common, understanding whether your site is crawlable by AI bots helps inform strategies for AI-driven visibility, complementing traditional SEO efforts.
Simple and Accessible Interface
Tools like this are typically designed with a straightforward, user-friendly interface where users can input a URL and get instant results, requiring no technical expertise to operate.
Helps Identify Robots.txt Issues
The checker can help identify if a site's robots.txt file is inadvertently blocking beneficial AI crawlers, allowing webmasters to make informed decisions about their crawl directives.
Other checkers list bots and say "allowed" or "blocked". We separate the crawlers that decide AI citations from the ones that only train models — GPTBot blocked costs you nothing, OAI-SearchBot blocked costs you every ChatGPT citation. 14 named agents, grouped by what each controls, with real robots.txt precedence parsing instead of string matching. Free, no signup.
Most checkers string-match bot names. We implement robots.txt precedence the way crawlers actually resolve it — most-specific group wins, * is only a fallback, wildcards and longest-match honoured — so configurations that trip up simpler tools get read correctly. And we tell you whether a block matters: GPTBot blocked costs nothing, OAI-SearchBot blocked costs every ChatGPT citation. 14 agents, grouped by what each controls. No signup, no email wall.
Marketing and SEO leads who've been asked whether their brand appears in ChatGPT, Perplexity or AI Overviews and have no way to check — plus the technical SEOs and developers who actually own robots.txt and have to make the fix. The tool is built for that handoff: plain-language consequences for the first group, exact robots.txt parsing the second group can trust.
It began as one check inside a larger SEO and AI-visibility audit, and it was the check people reacted to most — so in July 2026 we made it free and standalone. Then we found our own version was wrong: it applied the User-agent: * group even when a crawler had its own, reporting an explicitly-allowed PerplexityBot as blocked. Rewriting that parser to follow real robots.txt precedence is why we trust the verdict now.
AI Crawler Checker is free and requires no account, so there are no customers in the usual sense — we don't know who uses it, by design. It's used by SEO and marketing teams checking sites they're responsible for; usage skews heavily to desktop and to the US, UK and EU.
We have collected here some useful links to help you find out if AI Crawler Checker is good.
Check the traffic stats of AI Crawler Checker on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of AI Crawler Checker on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of AI Crawler Checker's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of AI Crawler Checker on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.
