If I type my site's(or pretty much any site) into google and get the page that says:
* Show Google's cache of google.com
* Find web pages that are similar to google.com
* Find web pages that link to google.com
* Find web pages from the site google.com
* Find web pages that contain the term "google.com"
If I click for google to show me the sites that contain the term, I see most of the sites that link to me. If I click on "link to" I see a much shorter list. Is there any reason for that? Do they update the "links" slower?
