Inbound links are links from other web sites that point to your web site. The number and the quality of inbound links has become one of the most important ranking factors in Google, Yahoo and MSN Search. It’s a simple principle: if Site A links to Site B then it is seen by the search engines as a recommendation; that Site  A is ‘recommending’ Site B. The text that is used within the link that is linked to your website is also very important (especially to Google). Try to include your keywords or phrases into the text that is linking to your site.
