Had a delima that is kicking my rear-end...high traffic day on my bball site (5 x my daily norm so far), but the CTR is down to around .3%. In the last month it has dropped from 1.5%ish to .5-.7 and now .3 today. No change in the layout of the site recently.
Site is collegehoopsvideo.com and am running the Google and YPN adsense plugin. Just changed the ad positioning to the random position, had been running in the top left for posts.
If anyone has advice on how to modify the ads to attempt to bump the CTR up some it is appreciated.
