How is CTR figured into your ads position?

[venrooy]

When they determine your ads position, I know that they use your CTR as part of the formula. Is it your daily CTR that is used for the formula, or is it your over all CTR from the beginning of the adword?

The reason I ask is this -

If the CTR that is used in the formula is figured on a daily basis, how will the new time zone setup effect this?

And if the CTR that is used in the formula is an average of your overall performance from the beginning of your adword, wouldn't it be best to start an adword with the highest bid possible, to get it to the top immediately? Other wise, if you are like most people, and try and start your adword off with the lowest bid possible, you risk dooming your adword to a low CTR, which may be difficult to overcome.

One more question - If you have an adword that is doomed with a low CTR average, is there a way to start fresh - Like to delete the keyword and start it up in a new campaign?

My guess is that they take into consideration overall CTR.
If it's a new campaign, they assume some CTR on the basis of other advertisers' history.
A lot of people adopt the tactic of bidding really high initially and thus, get a good 'Quality Score' and then gradually bring that(the bid) down.

If you delete a low performing word and add it again, I think Google will recognise it and use the same score it had previously, because you've already built some history...

I have CTR of 1-1.5% on my main keyword and I am ranked 1 -2 in Search... It is not as if I pay too much for the keyword.. I pay the minimum possible..

For the other Keyword , where I have 10% CTR , I am ranked 6-7..

CTR is not the prime deciding factor as far as I can see...

There must be other factors esp. the competition, your budget, monthly spend , history etc etc ..

Difficult to hazard a guess.

CTR is ranked in relation to competing CTRs... 10% might be extraordinary for a certain keyword on a particular match type while being entirely insufficient on another.

Furthermore, I do believe that CTRs are "equalized" to eliminate the bias of position.

Poster_boy mentioned that he think they are equalized to compensate for position. I'd like to hear other people's opinions on this.

I have noticed that my ctr can change from 3% to 0.8% just by moving from position 1 to position 8 on certain keywords.

If poster_boy is correct, then their formula looks roughly like CPC * CTR * (modifier based on average position). Does anyone have any evidence for this?

it is actually the all-time ctr for the keyword that matters, with the most recent 1000 impressions being weighted a bit more heavily.
