you have a huge image on top of the page. Take out that image and out google ads there. use a wide rectangle format and blend the colors with your site. youur click through will definitely improve. if you don't want to remove the image, consider putting the google ads on top of that image. either way put the ads on top of the page and use a wide reactangle format
Many ppl think their CTR is too low. But ppl earning HUGE from adsense have an avg CTR of 6-7% max. The key factor is the no. of unique visitors on your site. If that improves..so will your CTR... Get more traffic....GL!!!
experiment with posters' suggestions, wait a week or two and see if it makes any differences. that's what i did. (but i haven't found an optimal placing yet)
not true if you read on other threads people are making $80/day with 600 impressions. I get 10 times the impressions and make $4/day
Make sure that AS ads show up on every page... you only have them on your front page now.. You are missing out big time. Also I would probably ditch the AdLink unit and install a 728x90 leaderboard to see how that works.
