I've bough 2 micro niche site from the marketplace and now I'm trying to rank them. I am using GSA and I'm creating these kind of links: article, social bookmark, social networks and web 2.0 as the first tier, and for the second tier I'm using blog comments, wikis and image comments. I was wondering if this will be enough to rank the sites in a few weeks-months (or if i'm creating too many links?). Any feedback from guys who managed to rank micro niche sites with only GSA is appreciated! Thanks!
