Google AdSense Optimization – Large Rectangle (336 x 280) up to 6x Better

Submitted by Ryan Spoon on May 5, 2008 – 7:11 pmComments

Last week, I made a relatively minor change to the AdSense units on this site and consequently have seen 3.5-6x better CPMs… a remarkable difference.

On blog post permalinks, I used to have a 468 x 60 text unit between the post title and the article. I switched that unit to a large rectangle (336 x 280) that sits between the end of the post and the comments. That change alone resulted in 3.5-6x improved CPMs – sitewide! And that’s without making two changes that are probably more significant / effective:

1) Adding that same unit to the blog’s homepage and placing it between posts
2) Nesting the unit within the article on post permalinks (like below)

Other considerations:
- Testing the color and formatting of the unit
- Test rotation of text, image and video ads (all exist for that size)
- Adding Google Links Ads (you can have three text / image ad units per page and three link units)

Have any AdSense best practices?

    good article for google adsence.
  • well one of the most funniest place of advertisements was written in the middle of an article, and also the adsense was mentioned in the article like it was part of the article itself.. it really does create a lot of accidental clicks.
