I have been working on building a website for the last couple of months that I am using to promote affiliate products.  I spent a great deal of time learning what I needed to know about making the site search engine friendly.  I painstakingly wrote the content myself to be sure according to the search engine optimization guide that I chose to follow.  One thing the guide didn’t talk about was the important off page seo factors that were critical to god rankings.  Once I found a guide that taught Link Popularity Building things began to really look up for my site.
