AdWords vs AdSense CTR

[europeforvisitors]

In the AdWords forum, AdWordsAdvisor said that, in his (her?) experience, the average clickthrough rate for all Adwords was in the neighborhood of 2%.

I don't know how the average AdSense publisher's clickthrough rate compares with that, but the 2% number is lower than I would have expected for an average that includes Google's own SERPs.

I have very broad keywords that get 1% CTR on several thousand impressions a day, and a very high CTR (8% - 100%) depending on how targeted the term is and how competitive it is.

I think that AWA meant per AdWords campaign.

Lets say I have a leaderboard with the same 4 ads running all the time. Now with 100 impressions if each ad gets clicked on twice that would give me a 8% ctr, but each of the advertisers would only have a ctr of 2%.

You're right about the Google serps. Using the above example Google could in essence get as high of a 20% ctr with 10 ads and each one getting a 2% ctr.
