How to build high quality Backlinks?

1. Quality Content: essential. We cannot think of creating Backlinks to a website with poor content.
2. Leave comments: the most simple way to build Backlinks to your website is to leave comments on other people’s blogs. It is important to leave thoughtful and interesting comments in order not to be considered a Spammer and draw some people to your website!
3. Social Networking Websites: the list is really long.. MySpace, Lastfm, Flickr, Facebook, they all allow users to create a profile for themselves. You can “collect friends”, or try to be linked to as many friends as possible to promote your website. Here is a complete list of the most Social Networking websites.
4. Exchange links: you may also like to look for blogs with the same topics as your own and exchange links. I suggest not to exaggerate and not go crazy with it though
