Remember the number Google shows is so low compared to Yahoo, that is usually not hard to filter out your own URLs, especially since most are indented.

It’s also important to note that this low number Google reports to the public is of questionable value.

Personally, right now I’m skeptical that the number of links Google shows the public is of any value at all.

It’s generally believed that they are not showing all of the links that they are really “counting” and they are really not “counting” all of the links that they are showing in that public link: search anyway.
