In one of my websites, i recently put a graphical Leaderboard (728 x 90 - a long banner) on the dysfunctional main page where only 1% people go to my site through this page.
Having said that, the click-through rate for this graphic banner is 3.62%, resulting in 15% more revenue.
Comparing to other text ads that yield only 0.24% CTR, the graphic banner seems to be great, despite disturbing.
Do you also have similar experience with graphic ads? I'm thinking if I should put it on every content page - just not sure if my users like it or not.
