Why AI crawler access matters
If your robots.txt blocks the crawlers behind ChatGPT, Perplexity, Gemini, Claude and Copilot, those engines can never read or cite your pages, however good your content is. Many sites block them by accident with one overly broad rule. This free AI crawler access checker shows the gap in seconds and hands you the exact lines to fix it. Crawlable is step one; once engines can read you, run the AI visibility checker to see whether they actually name and cite you.
AI crawler access - FAQ
What is an AI crawler access checker?
It reads your site's robots.txt and shows, for every major AI crawler - GPTBot and OAI-SearchBot (ChatGPT), PerplexityBot, Google-Extended (Gemini), ClaudeBot, bingbot (Copilot) and more - whether you allow or block it. If a crawler is blocked, that AI engine cannot read or cite your site.
Why does blocking AI crawlers hurt my visibility?
AI answer engines can only cite pages they are allowed to crawl. If your robots.txt blocks OAI-SearchBot, PerplexityBot or Google-Extended, those engines will never surface your brand in answers - no matter how strong your content or SEO is. Many sites block these bots by accident.
Which AI crawlers does this tool check?
GPTBot, OAI-SearchBot and ChatGPT-User (OpenAI), PerplexityBot and Perplexity-User, Google-Extended (Gemini and AI Overviews), ClaudeBot and Claude-User (Anthropic), bingbot (Microsoft Copilot), Applebot-Extended, CCBot (Common Crawl), meta-externalagent, Amazonbot and Bytespider.
Is the AI crawler access checker free?
Yes, and no signup is needed. Enter your URL and we fetch your public robots.txt live, score your AI access out of 100, and give you a shareable report plus the exact robots.txt lines to unblock any AI crawlers you are currently denying.
How do I let AI crawlers read my site?
Add a robots.txt group for each blocked crawler with an empty Disallow (which means allow everything), or remove the Disallow rule that targets it. This tool generates the exact lines for the crawlers you currently block - copy them into https://yourdomain.com/robots.txt.
Is being crawlable enough to get cited by AI?
It is necessary but not sufficient. Crawl access is step one; being named and cited also depends on your content, entity signals and citations on trusted sources. Use EdenRank's AI Visibility Checker to see whether engines actually mention you once they can read you.
