I used one of this free list of " autoaproved " blogs that you can get here to an old ( 3 years old ) site that I have. Result ? From position 10th ( google usa ) I went to position 421 ! for main keyword in 2 weeks of blasts, lol. So I tried it with a blog web 2.0 sublink, again, from 14th position goes to 35th position in just 7 days ! So basically, if you hate someone, do sb for free, right now, is the best use for SB. And I did not even pass the 1000 back links per day, I have to try 10000 Back links per day and see what happen :44:.
