When you update information on your site, it doesn't instantly propagate to Google's index. Rather, Google's index is updated after our robots crawl a page. The crawl process is completely automated, so it's not necessary to submit updated or outdated links to us. Changes to your site's content will be noted when we next crawl your pages. Due to the volume of sites in our index, we cannot manually update pages on an individual basis.

If you've changed your URL, or plan to, and would like Google to display your new URL, please keep in mind that we can't manually change your listed address in our search results. That said, there are steps you can take to make sure your transition is smooth.

If your old URLs redirect to your new site using HTTP 301 (permanent) redirects, our crawler will discover the new URLs. For more information about 301 HTTP redirects, please see http://www.ietf.org/rfc/rfc2616.txt.

Google listings are based in part on our ability to find you from links on other sites. To preserve your rank and help our crawler find your new URL, you'll want to inform others who link to you of your change of address. To find a sampling of sites that link to yours, perform a link search by entering "link:[your full URL]" into the Google search box. To find more pages that mention your URL, perform a Google search on your URL and select the "Find web pages that contain the term" link. Also, don't forget to change any entries you may have in directories such as Yahoo! or the Open Directory Project.

Finally, you may submit a list of your new URLs through the Google Sitemaps (Beta) program. Google Sitemaps uses webmaster-generated Sitemap files to learn about your webpages and to direct our crawlers to new and updated content.

Sometimes during site transitions, we'll fail to find a site at its new address. Just be sure that others are linking to you, and we should discover your new site.

The Google index contains two types of pages -- fully indexed and partially indexed pages. Your page is currently partially indexed, which means that although we know about your site, our robots haven't read all the content on your pages in past crawls. This doesn't adversely affect your PageRank or your inclusion in our index. It does mean that we don't have detailed information about your page, so we display its URL as the title and omit a description. We understand the frustration this may cause you, and we're always working to increase the number of fully indexed pages in our search results.

Google's creation of snippets is completely automated and takes into account both the content of a page as well as references to it that appear on the web. We don't manually change sites' descriptions, but we're always working to make our snippets as relevant as possible.
