I was just looking through some pages on one of my sites, and I noticed some interesting ads displayed by Google AdSense.
These ads are blending the AdSense for Content Ad Unit, which I selected to display, but they are also working in some Link Unit creative to the creative.
Here is an example of one of the blended AdSense ads running on my site:

And here is another one:

The Ad Units are the detailed text ads at the top of each ad, and then Link Units are the series of four keywords at the bottom of each ad.
I’m not sure how long these types have ads have been out there, but this is the first time I’ve seen them in the wild.
They look a little cluttered for my taste, and I don’t see anywhere in the reporting to indicate the effectiveness of these ads versus the non-blended ads.
If anybody knows if this sort of report exists, please let me know.
