Maximum Number of AdSense Units

The AdSense blog has outlined the maximum number of each type of ad unit their program policies allow.

It’s actually more than I thought, so helpful to get the official word on it.

In order for your pages with AdSense to be compliant, they must not exceed the following:

ONE…
- video unit (currently only available in specific countries and languages, though we’re working to expand video units to additional publishers soon)

TWO…
- AdSense for search boxes

THREE…
- standard AdSense for content ad units, and
- 3 link units

Personally, I think this is excessive, unless you have a pretty long page with lots of text.
