Quick note on linking:
When search engines look at websites, one of the main things that they look at is Links. Both External (inbound links from other sites to your site) and Internal (links from one page in your site to another page in your site) are very important in the overall Search Engine Ranking structure. Additionally, Outbound Links (links from your site to other sites) are taken into account as well, but it is best to have more inbound then outbound.
Search Engines view links as “votes” or recommendations. By linking to a page in your site or on another site you are saying that relevant information can be found on that page. The more descriptive and relevant the anchor text of a link is, as well as the content around that link, the better.
