Adsense Experiment: Less Ads = More Revenue?!

Here it is, one of the many experiments I recently conducted.

• Experiment:Using smaller ads to try to increase cpc earnings
• Details: Switching from two large medium blocks to one 728 leaderboard, using blending techniques from Adsense Videos
• Verdict: Failure

Effect on CTR and earnings

Clicks (and therefore CTR) fell by 50%. Nothing beats having two medium blocks above the fold. PPC did increase slightly, but not as much I’d hoped. The lost clicks were not compensated for by the increased PPC.

Possible Errors

I consider myself something of a scientist, and according need to state that Adsense experiments are difficult because of the possibilities of errors. I generally run experiments for at least a week. It’s actually preadtty hard to see your earnings fall and not jump in.

People often say they can’t believe I sacrifice Adsense Earnings to make these posts. I don’t do experiments so I have something to write about; I do experiments to optimize my earnings, and sometimes that means takeing a hit for a week. It sometimes means finding something that doubles your CTR and earns you big money over the long run.

Next Adsense Experiment

I’m going to revert the Ad back to two med. blocks, or might decrease them to small blocks, but I’m going to again incorporate the blending techniques from Adsense Videos, which helped increase the CTR of this experiment by far.
