I signed up for an Adsense account about 3 months ago. When I click on products then on image only i placed a 468 by 60 banner on the top of my website and used the color codes orange from my control panel.

sure enough, i noticed even graphic image had some orange in it. my per click rate was something like 5 - 20 cents. I got fed up and thought the best thing ought to be multiple color patterns for my image code.

i highlight 20 image color codes for my adsense and bam! shot up to 1 - 10$ per click now all because i opened the door to non orange color image ads.

the lesson? use multiple colors for placing adsense images
