I would just like to know what the "teething period" is before a new ad will benefit from the CTR.
I'm happy with the new formula concept but what do I need to have my CTR factored in to my effective bid price?
do I need 1000 impressions?
do I need 100 clicks?
Do I need some other ratio of category Vs industry clicks over the total bid price of all advertisers minus the day parting average and the sum of the first number I think of?
