To build links first register your site in major directories such as the Yahoo! Directory and DMOZ and so many. Search engines often do not count links that go through redirects, so before spending money on a listing you will want to check if the directories provide static links or not. Mostly, directories that show tracking URLs do not provide links that are evaluated by search engines. Write press releases and articles and syndicate them on other websites. Link back to your site using your keywords when possible in the signature block of the article. Ask friends, product manufacturers, product distributors, and other business partners to link to your website. For building more links, sponsor sites and get them to link to you, also buy advertising from related websites.
