To me, as owner of a small online marketing agency in Calgary, Alberta, doing successful SEO for several years, links have always seemed like an effective way to raise ranking. Yet,even though I believed links to be powerful, I wanted definite proof, and have been following research on links as a ranking factor from several sources.
Lately, I found this study from Stone Temple by its founder Eric Enge. (I also just attended a Masters' Training on SEO Traffic Optimization at Pubcon in Vegas and Eric was one of the speakers. He is an incredible trainer with tons of knowledge and expertise on internet marketing. If you get a chance, go to conference like Pubcon, when he is a speaker. If you can't, at least read his blog.)
Since then Eric sent me some slides about the research. Here they are:
The study shows conclusively that links are still a powerful ranking factor. It is important to note, however, that quality links don't compensate for poor quality content or website. The research proves that if your site has good content, it will rank higher with good links. Without good content, the links will be much less effective.
