CRT/CPC/costs question

CRT from last 1000 impressions or all time CRT?

[ninhld]

As I understand, what we would pay for a click is based on CRT and CPC for that keyword.
But that CRT is CRT from the last 1000 impressions or all time CRT?

Could anyone clarify this?

pssst..

CRT = Cathode Ray Tube!
CTR = Click Through Rate

Again guessing here, but I assume that the system considers the All Time CTR to determine the avg position of your ads.

What you pay per click depends on your CTR/max CPC and your competitors' CPC/CTR

What you pay is based on your Max CPC and your CTR as compared to your competitors Max CPC, and their CTR in the moment your keyword is searched on, and your ad appears.

So at the risk of being redundant, it is not the CTR for all time, or the CTR for the last 1000 impressions that figures into the equation.

On a related subject, I owe another member a more detailed answer regarding positon and CPC from another thread - which I will try to get to soon. I have just not been able to carve out the half hour with a calculator required to answer the question accurately. ;) That post will shed a little additional light on this thread as well.

Hmm, I still don't understand! I do understand that cost assignment happens in real time, and that both Max CPC and CTR metrics are used to assign the costs.

But if costs aren't calculated using all-time-CTR or last-1000-CTR, then what kind of CTR is used? I can't imagine that it's using CTR for the last N hours?

Ok, I haven't explained this clearly, and I think I've confused the issue. Let me try again.

It is in fact the CTR for the keyword searched, in the moment in which it is searched. But, by definition, the CTR for a keyword in a given moment includes its entire past history.

So in this sense, it amounts to the same thing as the all-time CTR.

Sorry for confusion, ladies and gentlemen. :) I guess this is what happens when I post at the end of a long day.

Thanks a lot, AdWordsAdvisor!
AWA or anyone else, here's another question:

Does Adwords remember our CTR if we delete a keyword and subsequently re-add it? Does it remember it even if we move the keyword to another adgroup/campaign? If it doesn't, that would be another feature request I would like to add! :)
