I have read at many place that the color of ad, placement of adsense ad, themes etc. effect the CTR a lot, so any of you all experienced DP experts have shortlisted some word press themes and ad format which can give maximum results? can you all please share your experience on this?
The best wordpres-themes are the search engine friendly ones. Not all wordpress themes are search engines friendly. Of course only themes won't give you traffics, but themes are also important factor. Don't look for how cool theme are, but look for search engines friendly one.Try to search best wordpress themes in your search engine.
One of my very favorite themes for high CTR: http://wordpress.org/extend/themes/inove How to use: Install the Whydowork Adsense plugin -> http://www.whydowork.com/blog/whydowork-adsense-plugin/ Then, choose 2 ad blocks, the big 336x280 rectangle and the 468x60 banner. Using the plugin, make the 336 Code 1 and select "top right" for alignment and the 468 "bottom" for main page and posts. When you see the plugin, those instructions will make sense. In the sidebar, remove everything and replace with the "latest posts" and "tags" widgets. Now you're all setup for a nice CTR. I've tested this over several thousand niche sites with great results. Once you have enough traffic, you can experiment with ad size/placement. Good luck. TomG.
try to use the one the one which it comes with an ad admin that let you to adjust the place of ads. Good Luck
