I am sure that AWA has said in the past that the average click through rate for Google ads hovers just over 2%, so with 10 or 11 ads on a page the CTR on Google ads would be 20% or 22% on average.

Of course if you have an ad in the premium position which is very targeted to the search query, a very high CTR can be achieved (20% plus). Ads lower down should get clicks too, pushing the CTR of Google ads up.
