Clarify calculation of CTR

Is it done separately for each language/country?

[johannes]

A keyword's CTR is calculated from it's entire history and the last 1000 impressions are weighted more heavily.

1. Say that you have the exact same keyword in several campaigns, targeted for different countries or languages. Is the keyword's CTR calculated separately for each country/language? Or is it calculated for the whole account?

2. Does the keyword's CTR at Googles partner search sites count? (I know content sites don't count)

(I'm talking about the CTR used for establishing an ad's position and calculating the CPC, as described here:

1. Really good question! Interested to know the answer to this.

2. As I understand it, this is simply "No".

1. I'm about 95% sure that the keyword's CTR isn't seperated out by country or regional targeting, it's a combination of the keyword everywhere it appears in your account - but AWA can answer this one quickly.

2. Only Google's site counts for the bid rank formula CTR.

What if I create 2 separate campaigns targeting different countries but containing the same keyword?

IMO, CTR for a keyword will be the same, it does not matter where it locates in the account. (This is a reason why we have to delete a disabled keyword in entire account before we can re-introduce it.)

If the Max. CPCs for this keyword in all campaigns are the same, its ad-position ranking should be identical. However, the ad position will be different for each target country. For example,
keyword: blue widget
ad-position ranking = 2.50
Campaign 1: Country US -> ad position = 20
Campaign 2: Country Canada -> ad position = 3
Campaign 3: Countries UK, AU -> Ad-position = 10 for UK and 1 for AU.

In this case, I prefer to increase my Max. CPC for this keyword in Campaign 1 to get higher ad-position ranking so that my ad position in US market will jump from 20 to about 3-5 range if my ROI is allowed me to do so.

Yep, that is an interesting question.

Here is my educated opinion, at about a 99% certainly level. I'll consult/confirm with some Techsters later, and post again when I know more. So don't quote me when I say:

When the same keyword is used in multiple campaigns (which may be targeted to different countries) the CTR as it pertains to position is the CTR of the keyword in a particular Ad Group, while the CTR that pertains to disabling is measured across all appearances of the keyword in the entire account.

AWR (Now being a bigger risk-taker than usual, since I like to be 100% sure.)

OK.

Above 'opinion' is now confirmed. :)
