In 1998 Google changed the face of internet search engines. The two guys, who started google, sat down and asked themselves how can we make a better search engine. They changed the landscape of IT forever by believing that RELEVANCE was more important than keywords and meta data (these still are useful).
Relevance, they decided was a factor of two main things; who linked to your site, the more links the more relevant you must be. And did your site contain fresh and new content.
When Google robots/spiders scan your site, they are looking for relevance. How many people are linked to your site, how fresh is the content on your site.
Backlinks create RELEVANCE. So the more links you have on other peoples sites pointing to your site, the more relevant you site is, and you will organically float to page one search results.
One Super Easy Way to create Backlinks. As well as the Blog that's integrated into your website (creating Fresh Content and therefore RELEVANCE). Make sure you POST any blog entry you create onto an External Blog, and make sure there is a LINK back to your website site.
