This topic came up on site-reference.com and it is a common topic for people looking to improve SEO. It is important to know about because if you’re running a fansite or fan fiction archive and wanting to learn SEO through link building, this method is probably one of the first one’s you’ll see.
Commenting on blogs can help increase your traffic in two ways: 1) Click throughs on your name or from links in your comment. 2) Search engines if the links are not rel=nofollow. For the second, the advice is that the more you comment on a diverse range of blogs, the more search engine juice you’ll get and the more visits from Google you’ll get. Bad SEO people encourage you to comment as much as possible where ever the links are rel=follow. What these bad SEO people fail to tell you is that doing so can actually hurt your SEO because you may end up on blacklist as a spammer. People report spam to services they use like akismet, disqus, etc.
