The images below show the before and after of the ad placement on the right hand navigation. The image on the left shows the right hand navigation as it has been since this site was started. The image on the right shows the right hand navigation as of the posting of this article.

Advertising Placement
The current placement of the advertising is shown higher on the right hand navigation. I will watch the revenue received to determine if that makes a difference. To raise the CPC advertising I have lowered the 125×125 advertising. Therefore, looking at the images below you will see the difference is the block that reads “Ads” and shows a Toyota car has been moved.

After I collect some data I will post the results of whether the higher placement made a difference. Note that this change still does not place the advertising over the fold, or on the first screen that a visitor sees.

Results of Advertising Placement
This article was an old test but still worthwhile for you to do on your own site in an effort to optimize placement of ads.
