What Is Googlebot? Google's Crawler Explained
DICTIONARY · SEO

What Is Googlebot?

Googlebot is Google's crawler, the software that discovers and fetches pages for Google Search.

In plain English

It comes in variants, chiefly a smartphone crawler and a desktop one. The smartphone version does most of the work, because indexing is mobile-first.

Googlebot also renders pages, meaning it can execute JavaScript, though rendering happens in a second pass and is not guaranteed to be immediate.

What to know

Mobile-first
The smartphone crawler is the primary one for almost all sites.
Rendering
JavaScript is executed, but in a queued second stage rather than instantly.
Crawl rate
Adjusted automatically based on server response and site size.
Verification
Impersonation is common. Verify by reverse DNS lookup rather than by the user agent string.

Why it matters

Most technical diagnosis comes down to what Googlebot saw. Search Console's URL Inspection tool shows you the rendered HTML it actually received, which frequently differs from what you see in your own browser.

Common mistakes

×Serving different content to Googlebot than to users.
×Blocking CSS or JavaScript that the page needs to render.
×Trusting the user agent string, which anything can claim.
×Assuming a page rendered in your browser rendered for Googlebot.

FAQs

How do I see what Googlebot sees?

URL Inspection in Search Console, then view the rendered HTML and screenshot.

Can I control how often it crawls?

Not directly any more. Server speed and site quality influence it more than settings do.
