Fastest way of link building

According to me forums are the good one for the links.

- Submission of RSS feeds to feed directories
- Social bookmarking submission

Just Find some Forum related to your content and post on them. then register in social network websites and create fan page.

I think blog commenting and forum posting can help to build backlinks in quick time.But we should maintain quality in our link building work.Because only quality backlinks can help us to improve search engine ranking.
Thanks

Though automated link building submission is literally the fastest way to get backlinks, it is not recommended by many SEO experts because it might hurt search engine rankings and the worst case is getting banned.

It depends on the quality of the website on which you are creating backling, if teh site is authority site, it will help you reallly fast..
