I had talked about the importance of getting lots of back links to your site in one of my earlier articles. Back links are important for ranking well in the search engines. Back Link building is also called Off Page Optimization in SEO.

When you build links to your site, which websites link back to your site and the page rank of that website are important. Linking with websites that dont count with the search engines is a wasted effort.

Search engines consider the keywords used in the anchor text in linking back to your site. If your website is about money making than the anchor text: money making tips may be given more importance than the anchor text: recommended website.

Search engines also take into account the page title of the website linking to you. The website should be considered to be an authority site by a search engine like Google for the back link to get more importance.

In nutshell, you should try to get quality back links from those sites that are related to your websites niche. Those sites should be considered as authority sites by the search engines like Google. The anchor text used to link back to your website should contain your websites niche related keyword.

Getting back links from authority sites is what counts with the search engines. But it is not easy to get links from authority sites. How to go about it?

You must have heard about social book marking sites. Social book marking sites like del.icio.us, digg, furl, propeller, stumble upon etc are very popular with Google. Most of them have a page rank of 6+.

Bookmarking your website on these social sites can get you lots of quality one way links. You should also not forget, many people visit these social bookmarking sites, so you can get many visitors in addition to back links as well.
