Googlebot is Google's main search crawler. It discovers and indexes pages for Google Search, the foundation of most organic traffic on the web. It is a search crawler, and it is the single most consequential bot to keep allowed.
Blocking Googlebot means your pages can't be indexed or ranked, so you disappear from Google's results. Accidental blocks — often a leftover Disallow: / from a staging site — are a common and costly mistake.
How to check and control it
To check, look in your robots.txt for a rule targeting this user-agent. To allow or block it:
User-agent: Googlebot
Disallow: / # blocks it — remove or set "Allow: /" to permitFor an instant check across your whole site, use SEO AEO Specialist's free AI crawler checker, and see the llms.txt & AI crawler guide.
FAQ
What happens if I block Googlebot?
Your site is removed from Google Search indexing, so pages stop appearing in results and organic traffic collapses. This is rarely intentional and often caused by a leftover staging rule. Verifying Googlebot access is one of the most important robots.txt checks you can run.
How do I know if Googlebot is accidentally blocked?
Look for a Disallow: / under User-agent: Googlebot or User-agent: *. A single stray rule can deindex your whole site. SEO AEO Specialist scans your robots.txt and pages to catch accidental blocks and helps you fix them, not just monitor them.
