So I've noticed that on one of my low competition sites, the site moved up from being under google places to being over google places with just one high quality social bookmark, that got some likes and some retweets. Now, I don't know if the likes and retweets had an effect, but I sure as hell like having one link itself provide some movement. Anyway, I am keen on using some software to build up accounts etc so that I can do these likes, diggs, retweets myself. Like when I create a web 2.0, I think it will help indexing as well as ranking if all of them have some likes and retweets. So, is anyone doing something like this? And what type of tools would I need to get the retweets and Facebook likes down pat? I'm thinking the facebook side of things might be hard, but retweets should be do able? Mainly wondering if anyone out there is using this on their tiered sites.
