Googlebot: how the search crawler works (and how to work with it)
Learn how Googlebot crawls sites, what limits and priorities it uses, and how to check crawl issues without guesswork.
Googlebot is the name of Google’s web crawler. Think of it as the browser that visits your pages on behalf of the search engine.
It reads your content, follows links, and sends everything back to Google’s index. Without a crawler, your pages can’t appear in search results.
How Googlebot decides what to crawl
Googlebot doesn’t crawl everything. It follows a set of rules and priorities:
- robots.txt: can block or allow paths
- crawl budget: how many pages Googlebot is willing to crawl on your site in a given period
- link graph: which pages are linked from other trusted sites
- freshness: pages that change often may be revisited more frequently
- site health: pages with errors may be deprioritized
Crawl budget basics
Crawl budget is not a single number. It’s the combination of:
- Crawl rate limit: how fast Googlebot can crawl without overwhelming your server
- Crawl demand: how interested Google is in your content
Sites with lots of low-value pages will waste crawl budget. Focus on making important pages easy to reach.
How to check Googlebot activity
You have two good places to look:
- Google Search Console → Crawl Stats (shows recent crawl activity)
- Server logs (shows exact requests from Googlebot)
Verify that requests are real Googlebot by checking reverse DNS. Or use our Bot Simulator to see what a crawler sees.
What breaks Googlebot
Common issues include:
- server timeouts or 5xx errors
- soft 404 pages
- misconfigured robots.txt
- JavaScript that loads content too slowly
- canonical tags pointing to the wrong place
If Googlebot can’t access your content, it can’t rank it.
