Adsense layout in my site. need advice.

[born2run]

Hi, in my site news articles are published.

I have used the following ad layout: 160x600 ad- content - 160x600 ad

A few months ago I had tried the following layout: content -- 300x250 ads.

That experimental layout didn't earn as much money as the 160x600 so I switched back to 160x600 ad-content-160x600 ad. I tested the experimental layout for about 2 weeks.

Can you guys give me advice on what's the optimal ad layout for my site? The current configuration looks congested and seems like ads are everywhere.

Kindly assist. Thanks!

It depends how long the content is, but as long as 2 ads are never visible at the same time I would try
First two paras of content
300*250 ad
Rest of content
300*250 ad
With 320*100 ad replacing the first of these on mobiles
I don't float ads in content because it often looks ugly on narrower screens but that is another option to try.
