How long does it take for Googlebot to recrawl a page?

Clayton SEO from South Africa asks, say your index page or any page on your site has been cached by Google, crawled and indexed by Google.

And then you change the meta description.

How long does it take for a Googlebot to recrawl that page, or must you request it via Webmaster tools?

Thanks.

So essentially, Clayton SEO is asking, Well, you've crawled my page.

How often can I expect to have it refreshed?

And we set a goal that we refresh a large fraction of our

index every few days.

It used to be that we would crawl the web and re index it roughly every month.

And while you would still love to refresh every single part of your index on roughly that kind of a time frame, sometimes content changes very slowly.

So there are a few cases where if we haven't seen the content change the last 18 times that we visited, then maybe the

19th time we'll wait even longer.

But in general, when there's regular content and it's in our opinion, an important content, we will try to revisit that page relatively often to see whether it's changed or whether there's any new information on it.

So usually you shouldn't need to wait more than a few days.

It can happen that if you have not very much page rank or your page hasn't changed that much further, very long time, then it can take longer.

But in the typical case, it shouldn't take very long at all
