For me, it is Craigslist and articles. I am able to post in categories that define my visitor on craigslist. And, for articles, I am able to write them geared to a certain niche and post them in certain categories.
there are many kind of backlinks in off-page seo. like web 2.0, Press release, Profile, Article submission etc. I just want to know from experts that which kind of backlink is the best and how to the submission system. By system I just mean, If article how much word, or how many hyper in every article etc. Thank you all
