I’m not certain exactly when this happened, but Epinions, the grand daddy of review sites, went social and could offer a good opportunity for niche marketers to build authority and gain highly targeted visitors. Epinions now has social networking profiles and offers the ability to build up a web of trust (i.e. friends) with other reviewers in your niche.

I am not advocating doing affiliate marketing and dropping links on Epinions at all! (Affiliate links are prohibited.) What I’m suggesting is that if you have a baby site and did regular reviews about baby products, you could built up your “web of trust” (who would probably be other parents), establish yourself as an expert in the field, build up a following to your baby site and maybe even generate some good traffic.
