There are lots of SEO experts wondering how frequent does Google updates its website listing in results pages or the updates on indexed web pages. Actually, no one has the knowledge about this except people from Google themselves.

All the SEO experts know is that Google updates more frequent than any other search engines. Almost every month, Google comes up with newly indexed web pages. The frequently updating of Google in its indexing and search engine ranking is also the reason why some of the page rank and even search engine ranking are diminishing quickly. Some sites that are ranking far from the top are ranking in the top 10 search results. Some sites that are ranking well goes down the web listing. There are many considerations and reasons why Google behaves this way.

The only resort to get desired results is to be patient with the continuous optimising processes such as link building and linking in and out through blog posting and commenting. Some SEO experts assume that Google takes out your top placement in the search engine ranking so that some of your web pages will be thoroughly crawled. After the crawling some of your web pages, your ranking is given back, not right away but in time that you can patiently wait.
