Why doesn't Google pick up all the links to my sites that yahoo and msn does? What are google's requirements for links?
you have to wait for a google (pr) update for backlinks to show up.. also i've heard that only pr3 or higher backlinks are shown
Google has for long period of time been showing a sampling of links to your site. It will for now never show all of the backlinks that you have.
Yes, as Cnadianbacon mentioned a BL update is usually done before the PR update. It is quite common to have several BL updates to 1 PR update. Also the PR is actually much older, google calculate it real-time. And you just see old results. Brad
