Link building for articles is obviously a little different from building links to a wordpress blog (which is what I normally do) so I'm seeking some advice. Obviously I've been using social bookmarks. Those help me stay indexed and ranked and are a key part of what I do. I make those with bookmarking demon. I also do some commenting on wordpress blogs with scrapebox. Additionally, I want to add some vbulletin profiles. I have a few questions. First of all, is it likely these vbulletin profile links that are ezinearticles links will stay up long term? I always had very good success linking to my blog, which is a hosted domain, but not sure if the moderators will be cool with ezine articles in a profile. Some of my articles are about adult topics, as well. Also, what are some other options for getting high quality backlinks for ezinearticles? Seems it would be harder to get .edu when you are posting articles about penis enlargement. Any feedback would be great. Thanks for reading.
