I have a Blogging and link building related site, just wondering if a backlink from adult site will make trouble for me...
Link Back offers detailed information on the websites in your area of activity concerning page rank, back-link number, and evolution in time.
It's going to help you with the PageRank, but if you don't have enough other links from authority websites, it might actually have some negative consequences.
I think better you should avoid it, it would be considered as a bad neighbourhood in your linking network.
Unless you site is an adult site, i don't think it is a good idea to get back links from adult sites.
