Do the usual linkbuilding techniques such as forum posting, link exchange, directory submission, social bookmarking, article submission, etc. These methods work.
Write quality unique articles and submit them to article directories. But don't write as a commercial article directories will reject your article. So be careful and try to write rich articles and submit them to high PR sites.
HI dear if you want link exchange then you should keen on only good pr and relavent quality site. if your site is new then only content link. no futter and side wide link.
