Yes, link units do affect CPM because you get no credit when someone clicks on a link unit ad and only when they click on an actual ad on the next page you get a click. Thus at least your CTR will be halved or worse.
I just compared the CTR of a link unit in the left nav area
with a 300x250 unit also in the left nav area
The AdLink has the higher CTR.
Maybe a admin can splice this to the other thread
What I just noticed, at Google AdSense statistics, when I make a statistic for AdLinks only, the show in the first column how many times the AdLink was clicked and in the second column how many ads have been clicked.
It seems a click on an AdLink leads to multiple clicks in the shown page.
This month are nearly 50% of all clicks only on AdLinks
Mine are the same and have been since AdLinks introduction.
A third to a half of my earnings are from adlinks but they are on fewer than 10% of my pages. And they take up such a small amount of space, too!
And FWIW, CTR and EPC are better than adblocks....
