I have two websites that are quite old now (about 5 years each) and last month I decided to buy some link packages to them. I got about 15 2.0 properties, some slideshares and videos, but all of this where very thin content (I probably should have known), and I am worried that google might penalize my site for these. But insted of letting these "websites" go to waste, I thought I might build out these sites somewhat, make them minisites I link to my webpages. Do you guys think this might be a good idea, or will google still catch on to this funny business. I were thinking adding posts to these properties over time, so that they have about 5 each in a few months time. Or should I just remove them alltogether? Or does google not care for such low number of bad links and will not care?
