Google’s John Mueller Reveals How Often a Site is Re-indexed in Search
In Google’s latest Q&A video, John Mueller answers a question from a site owner concerned about their site not being crawled often enough.
“How often does Google re-index a website? It seems like it’s much less often than it used to be. We add or remove pages from our site, and it’s weeks before those changes are reflected in Google Search.”
Mueller explains that it takes time to crawl entire websites. If Googlebot were to crawl a whole site in a short period of time it would cause unnecessary strain on the server. For that reason, Googlebot has a strict limit on the number of pages it can crawl every day (exact number was not mentioned).
