I was using a tool (
http://www.kenkai.com/seo-tools-link-popularity.php ) , which I found somewhere on this forum and when I entered my site's URL to the number of inbound links to my site there were results from Yahoo,Altavista,AllTheWeb but there were no results from Google and MSN......I am not sure whether this data is correct or not,I guess if there are links from Yahoo then there must be links from Google as well......
Can somebody suggest me why this might have happened?
