Ok so on multiple sites over the last 3 weeks i have been directing traffic through www.ygfnet.com and i have seen my rank increase to 3 of 10 in three weeks in one case and the rest of my sites have gone from 0 to 1 and 2. Aside from getting my rank increased and bettering my odds of getting business, i have also seen an increase in my adsense income from nearly non existence to 20-60 dollars a day.
You have to check out this site, it is definately worth the time it takes.
