In one of my earlier articles, I had talked about the importance of getting lots of back links to your site in order to rank well in the search engines. Building links is also known as Off Page Optimization.

Websites that link back to your site and the page rank of those websites are important. Linking with irrelevant websites dont count with the search engines and is a wasted effort. How do search engines decide about the relevance of the website linking back to your website?

Search engines also consider the anchor text used in linking back to your site. For example, if your website is about dating than the anchor text: dating tips may be given more importance than the anchor text: recommended website.

Search engines also like to take into account the page title of the site page that is linking to your site. Some sites are considered to be authority sites by the search engines. Back links from authority sites are very valuable.

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.

So, getting lots of back links from authority sites is what counts with the search engines. How to go about getting lots of back links from authority sites?

Everybody knows about social book marking sites and how they work. Social book marking sites like del.icio.us, digg, furl, propeller stumbleupon etc are considered as authority sites by search engines. Most of these social bookmarking sites have a page rank of 6+.
