Effective SEO link Building?

[Albertlu]

We are often told that one of the best ways to build backlinks is to post relevant comments (not spam) in blogs/forums. Posting comments in any blog/forum are however not going to help if your intention is to build backlinks. More importantly you should always look for high page rank blogs/forums that have “dofollow” attribute to leave your comments to build backlinks. When it is a “nofollow” blog/forum, your effort to create backlinks will be wasted. It is important to know whether you are leaving comment on a “dofollow” blog or not in your backlink building process.

It solves the problem of duplicate content. So, we always go for white hat techniques and unique content. Content must be updated and with full of quality.
