I made around 10 T1 links on web 2.0 and then added around 100 T2 PR1+ links using GSA (articles only) and on top of that i added around 1000 GSA t3( article only) and 10 000 blog comments to T3. I expected for my rankings to improve since it is an easy keyword but nothing happened, i even lost rankings of most my T1 sites (web 2.0). So my conclusion is that GSA links doesn't work. Is there any better software for T2 links that can build around link from around 100 different sites and is it safe to use GSA for making T3 links? I do T1 manually using unique articles, but i cannot build the T2 links manually since it would take too much time.
