I own quite a few websites and a lot of them are wordpress websites. I do not allow comments that have not been moderated, and honestly I never moderate them. That being said, tonight I was working on one of my authority websites and decided I would check out a few of the 1,600 some odd comments that people have left on the site. As I strolled through the comments, I realized that there are a lot of keywords that I could dominate in the list of comments. After realizing this, I came here to BHW to post this, before I forget. So, if you own websites with wordpress on them and people leave comments, maybe you have quite a few golden nuggets on your own website that you could dominate. If you don't own a website with wordpress on it, then you should set one up, just for keywords. I would choose a large niche. Something like "make money online" or something that a lot of people try to get ranking for. Then I would just build a dumper website on this niche and let the keyword stealing begin.
