When I go to google and type link:www.mysite.com google finds a few sites linking to me. But with other tools I find hundreds of sites linking to me. Does anyone know, how does Google decide which sites to find that are linking to you? And does this effect page rank? Ie, are there only certain types of links that are important in Google's eyes, and are those the ones that show up on the link:www.mysite.com searches? Thanks, if anyone knows anything about this.
