Which Ad Format Produces The Best Results?

Which adsense ad size gets the most results?

Here is an excerpt from some of my notes:

"Use the Large Rectangle-With Google Adsense, you have the option of picking different ad formats. Most of the time people opt to use the Leaderboard (728x90) or Wide Skyscraper (160x600) style ads. Unfortunately, this is the wrong choice, because both look like blatant advertisements. Instead smart webmasters have found that using the Large Rectangle (336x280) yields the best amount of click-thrus.


* Don't use the Adsense 486x60 sized ad as it is generally ignored.


* Make them more noticeable by positioning your AdSense ads on top of your AdSense page.


* Google states that the most effective ad formats are 336×280 larger rectangle, the 300×250 inline rectangle, and the 160×600 wide skyscraper. However you should choose the best AdSense ad format that works for your AdSense web site. This requires tracking and testing.
