I have seen my site http://www.grassrootstrading.com/ increase from a google page rank of 2 in March to the current PR of 5. My disappointment though is that I have not yet seen an appreciable increase in hits. I'm currently working on adding more content and backlinks...banner exchanges..free classifieds and so on. I have tried PPC, and I have a pretty good idea which provider gives me the best ROI, but my ad budget is somewhat nonexistent.

Any idea what I could be missing?
