Basically, or Build/Buy Backlinks! Im going to try to buy some backlinks. Plugrush helps, I dont buy any traffic from them, but there is value with exposure. If you offer something people will come back too, then you can only suspect that people will continue to come back. Ive opened up my site's images to thumbnail sharing on sites like this, hopefully that will help! Here is an example of one!
Maybe Ill post a gallery on the site, but I forget where people put them.
