Signature with desired anchor text on blog would count as backlinks by SE? What if register many free blogs and backlink to own sites? Could this be an easy way build thousands of backlinks? Acne Treatments | Natural Acne Treatments | Acne Products REVIEW
I think they will be taken as backlinks unless there're "nofollow" tags. But i don't think they would be same quality.
Most blogs use nofollow tag in their comments. But this still could be a nice source of targeted traffic. Just make sure you're not spamming.
Creating 1000s of your own blogs to link to your site. Congratz you have just self learnt a form of blackhat seo lol. Not recommended.
Signatures ion forums like DP are not considered as backlinks.. Maybe blogs which allow "do follow" tags get you backlinks..
Of course forum signitures count as backlinks but only if they don't use nofollow (there's no such thing as a "do follow" tag) and DP doesn't use nofollow. However, most forums use nofollow as do most blogs. But the issue is not whether forum signitures and blog comments are backlinks be cause they are if they don't use nofollow tags, but whether the search engines will recognize that you own the 1000 blogs that link to your site and consider it as interlinking. I'm sure everyone knows the answer to that.
