How Googlebot Crawls the Web



In this episode of Search Off the Record, Martin and Gary from the Google Search Relations team take a deep dive into how Googlebot and web crawling work—past, present, and future. Through their humorous and thoughtful conversation, they explore how crawling evolved from the early days of the internet, when scripts could index a chunk of the web from a single homepage, to the more complex and considerate systems used today. They discuss the basics of what a crawler is, how tools like cURL or Wget relate, and how policies like robots.txt ensure crawlers play nice with web infrastructure.

The conversation also covers Google’s internal shift to unified infrastructure for all crawling needs, highlighting how different teams moved from separate crawlers to a shared system that enforces consistent policies. They explain why some fetches bypass robots.txt (like user-initiated actions) and the rising impact of automated traffic from new products and AI agents. With a nod to initiatives like Common Crawl, the episode ends with a look at the road ahead, acknowledging growing internet congestion but remaining optimistic about the web’s capacity to adapt.

  1. Liar info to intentionally harm….
    And they won’t cooperate with IP addresses to take it down. We can have all the information photographs, etc., etc. and they don’t care. And it keeps reposting. Even not googling and not looking at it is seeing off of Google. You can look six months later and it’ll still be there. You could still send them a message they don’t help at all.

  2. Google is the worst False info represented over Google and other search engines that destroyed my reputation from people posting lies from stalkers. And it’s impossible to change and take down. Needless to say lots of jobs hard time finding a place to live and family and friends disowning you. All to false information on Googlespoken to Google 1000 times police report nobody does nothing. This is going on for eight years plus I’m still trying to take things down. And now they just ignore you. Have had repetition correctors and lawyers. And they still don’t cooperate. They keep accepting posts from unknown sources and keep posting negative information.

  3. Disappointing. I doubt anyone watching this wants to discuss the 1990s. With input from a team leader (or anyone closer to the development process) and a little preparation, this could have provided some real value in half the time.

  4. I hope you are employed at Google for the rest of your long lives, because this unprofessionalism and lack of useful content wouldn't fly at any other company.

  5. Hello.
    Before moving the podcast to YouTube, a document containing the video script was published with each podcast.
    This was helpful as it made the content more accessible to non-English speakers, at least for translation.

    Would you like to share the video script in future videos or elsewhere? Please.

    Thank you very much.
