Peter asks: Sometimes not all the ads display in each ad unit – for example there will only be 2 ads in the medium rectangle ad unit instead of 4. Is this normal?

We say: Yes, this is normal. With expanded text ads, AdSense technology automatically displays fewer ads when we determine that larger ads will perform better on a particular page. This should improve monetization for you.


Wayne asks: The Inside Adsense blog says that publishers can maximize their income by having multiple ad units on their web pages. Is this new? Last year I got an email from Google telling me that I wasn't allowed to have more than one ad unit per page.

We say: Yes, on each page of your site AdSense is now able to support up to:

• 3 ad units
  
• 2 AdSense for search boxes
  
• 1 link unit
  
• 1 referral button per product (i.e., 1 AdSense referral button and 1 Firefox plus Google Toolbar referral button).
  

Chris asks: How does AdSense treat websites using frames?

We say: In order to use AdSense on a frames-based page, you'll need to follow two steps. First, when generating your AdSense ad code, make sure to check the 'Framed page' checkbox. Next, you'll need to paste your AdSense code in the primary content frame of your site. Pasting the AdSense code in the same frame as your site content allows our crawlers to understand your page and serve relevant ads accordingly.
