So I bought a course and tried it. I created an MFA site, in the way the course suggested, and then back linked it to a few sites of 3 or better page rank. I even did a couple of anchored back links using my site's main keyword.
The site has not been found after three plus weeks and I went on to Google's webmaster forum and a few of their "Top Contributors" said that creating sites strictly for AdSense was useless. Does anybody concur?
(I am not sure if I am allowed to show the site here, but the course had me word the copy so that I reaffirmed the keyword a lot. It also has a .me extension because I chose a domain name based on a keyword that had significant monthly searches so it could be part of the url.)
