How long does it take for all 200 ranking signals in an algorithm to be refreshed? So for instance, if I update my website now, how long will it take until everything is updated?
JOHN MEULLER (Webmaster Analyst from Google):
We don’t actually have any specific time frame for everything being updated. To a big extent, these are things that are all running in parallel and all running kind of in different cycles. So some of these update very quickly. Some of these take a little bit longer to be updated. So it’s not something where there’s a simple– like a monthly basis where we would say everything is updated at the first of the month. It really depends a lot. And it also depends a bit on the website itself, how often we crawl individual pages from that website in the sense that some pages on every website are crawled very frequently. Sometimes every couple of minutes even. We use those to kind of update things that we think are fast changing. And a lot of pages on most websites are crawled very infrequently. That might be several months in between. Or maybe even up to a year. So when you look at something like that for a website even just from crawling the content, it can take anywhere from several minutes to a couple of months for that to even be updated on our side. And the various algorithms that we have, they do try to be fast in responding to what’s out there on the web. But some of them are fast. Some of them are a bit slower. Some of them like to take into account more of the history of what has been changing there.
