I just have a second for a quick tip but this is a good one for those of you new to link building. If you have ever done a backlink search on a competitor to find out where they have their links from you often find that a large majority of the links are from their own site. It can be a real pain separating the wheat from the chaffe so here is a little trick on Yahoo (the best place to do link building).
Conduct the following search in Yahoo replacing “domain.com” with your competitor’s address:
The result is a listing of all the sites your competitor has gotten links from minus your competitor’s own pages. This is a handy little tool. Now if you want to do this faster you can always pick up OptiLink – a program that we use religiously when we are conducting link building campaigns. Visit our recommended SEO tools section of the SEO Blog for this one and much more.
