Slyscraper vs Medium rectangle

...

[malasorte]

Hello,

Until now my ad format was a Skyscraper. Put on pages with a lot of content, I always had 5 ads displayed in this type of ad unit. Recently I moved to a Medium rectangle, it works better for my pages. But... Sometimes the medium rectangle displays 4 ads (the maximum) and sometimes only 2. How could that be? I've put the Medium rectangle on the same pages where the Skyscraper always displayed 5 ads.
What can I do so my medium rectangle will always display 4 ads?

AdSenseAdvisor and thoughts on this?

If the ads fill the frame, you are seeing what AdSense calls Expanded Ads. When their algorithm predicts you will earn better if they do it, they put fewer, larger ads.

This is a fairly new feature, but I'm sure you can find information about it at AdSense help pages....

It sounds like you are seeing expanded text ads. To quote the AdSense Support site ([google.com ]):

Keyword-targeted text ads may also be expanded when we determine that a larger ad will perform better for a particular page. Our AdSense technology will automatically determine the optimal number of ads to display and will only show fewer ads when it improves monetization.

The ads don't fill the frame, but yes the text is larger. Expanded Ads... If Google thinks this is best for me/them, I will go with Google :)

Thanks for your answers, It's great this forum exists and people are so nice.

Forgot this: the weird thing is that I get expanded ads or normal ads on all of my pages. I mean there aren't pages that show normal ads and pages that show expanded ads, at once.
