Hey snaskit, 20,000 hits/day sure is a lot! Where was most of your traffic coming from? Social Bookmarking sites? Search engines or a combination of both? You have to make sure that you're getting quality traffic (aka targeted traffic) to your site. A lot of non-targeted hits/impressions does nothing but bring your CTR down and inevitably getting you smart-priced. I would recommending checking the stats on your web server and or install google analytics to get a better glimpse of where your traffic is coming from.
