Link building or obtaining back links is a complex process of attaining links back to a website. This can help with search engine optimization and build more value in a websites position on the Internet.

In general, the theory is that the more back links you get to your website the higher it will be ranked in the search engines. This however, is simply not the case. There are a number of other factors besides the number of back links to a site, which affect a websites' ability to rank highly in the search engines. The search engines are made up of very complex mathematical algorithms and weighted by many different factors and are in a state of constant change.
