For the purpose of this question the QS means CTR only. You're a new bidder on a keyword in the auction and the system assumes that your ad will have the average CTR that other ads historically had - which is shit - and will charge up the wazoo until your ad performs otherwise (better than expected). Basically, it's a "guilty until proven innocent" system where new advertisers are forced to bleed cash just get their foot in the auction. Fair? Probably not. Very profitable for Google? Yes. Anyway, here's my question:
After how many clicks does Google take a look at your ad's CTR and goes "ok this ad's CTR sucks compared to what we expected" or "o wow, this ad rules" or "meh average" or whatever?
P.S. I figured they go by a certain number of clicks, not impressions because some keywords will take 10 impressions to get a click and some will take 70. Giving a fixed number of impressions to the new ad would not make sense.
