Question

Anyone knows how to track the CTR based on banner size? running a GDN responsive ad

Answer 1

Nope you can't, you can only asses the ad performance on the "Asset Details Level" and only as "Low, Good, Best" (whatever they mean)

George, ok, so the CTR can’t be determined, but what if you just want to track what banner size your website visitors clicked on ? there is no way to track that either?  

Answer 2

You can in Google Analytics as some standard or custom report I can't remember right now

Of course if everything is installed and linked properly.
