Hi I have some pages indexed in google and I made some changes yesterday to those pages but google still didnt refresh those pages in index. Any Idea how long does it usually takes to get updated those pages in google ?
It depends on how often the Googlebot visits your site, and how often your home and inner pages are re-indexed. If you are ranked highly, you'll get your new pages indexed and altered pages re-indexed in less than a day. If your site has pretty low page rank, Googlebot will visit less often, and update the index less often. I completely rebuilt about 10 of the pages on one of my sites with a PR2, and it took Google about 2 weeks to update the index.
If you don't think changes are happening quick enough, you can always update your crawl frequency under Google webmaster tools.
It depends how many times a day the Googlebot visits your website - the more backlinks and higher authoritive links that you have; the more it'll visit.
No you can't, you can't tell google how often you would like it to come round. Google will crawl your site if you have the old SEO standards of backlinks and fresh content. If you always have something new when it does crawl, the frequency of it's visit will pick up over time.
that totally depends upon your backlinks.But u can try out increasing google crawler frequency of visiting your website with google webmaster's tool.
Within 2 or 3 days your pages will crawl... Bcoz generally once Google crawl that page then its bot or its spider comes randomly on that pages.
