I took one of the Yahoo Group backlink appreciation packs last night - and I was about to post a message on here letting everyone know I grabbed one - but low and behold my order is already finished. That's less than 12 hours turnaround from the time of payment - fastest service I have ever received on a (censored - Forum name) purchase so this seller is solid! Report is easy to understand and I think these Yahoo group links will be a cheap way to add some backlink diversity to my site. Highly recommended. I am top slot on page 2 of Yahoo for my main key phrase, so hopefully this might push me onto page 1. I will report back, but just based on speed alone and the report quality this is a great deal for the $$$.

For a trial, I will post your Website with your keyword to 330 Yahoo Groups. When I had blast my website to Yahoo groups so in return I get more than 25+ backlinks visible in Google Backlink Checker and more than 100+ or even more (never count but assumption by looking at Yahoo Explorer)
