About this episode

This episode discusses the complexities of Google's crawling infrastructure and the misconceptions surrounding Googlebot.

Developers often talk about Googlebot as if it were a single program you could just run as "googlebot.exe", but that is not how Google's crawling actually works. In this episode of Search Off the Record, Martin and Gary from the Search Relations team unpack how Google's crawling infrastructure is really built and operated.​ They cover why "Googlebot" is a misnomer and how it relates to a central crawling software-as-a-service used by many Google products​, how crawl behavior is controlled centrally to avoid overwhelming sites (throttling, handling 503s, and "don't break the internet" safeguards)​ and more! If you build for the web, work on SEO, or just want a more accurate mental model of how Google crawls pages, this behind‑the‑scenes discussion is for you.
