I have been link building for a couple months now. I am having a hard time trying to figure out which sites are even worthy of getting links from. Obviously, those that are clearly link farming, or have lots of ads throughout their site are not valuable. I use OSE, but don't know what is a good P.A or D.A. and what it means when one is much higher than the other (and if that is a bad thing). I also use compete.com to give me a general idea of the unique visitors going into a site. Any tools I can use to help evaluate the strength of specific incoming links/ specific websites? Any ideas or thoughts would be helpful. Thanks So Much, Melissa
