Hi, Me and my friend were working together on some websites and were using ads from the adsense account 'A' which was on my friends name.Last month we decided to work separately.I had a old adsense account 'B' on my name on which one small website with little earnings was there for last 1-2 years. Now i have changed all the ads on my websites to my own account i.e. from 'A' to 'B'. My CPC has dropped considerably after this. My website's some pages still have account 'A' ads and those ads are getting the same good CPC that i was getting earlier. Does changing the adsense account (from a good earning account 'A' to a little earning account 'B') affects the adsense CPC? Does Google gives adsense CPC according to how much good business(earnings) the account is doing with Google?
Changing the adsense account doesnt affect the adsense CPC as the CPC is based on the keyword (atleast in theory) performance.
if the DNS owner was not changed you have to give some time to yours ads performance better . Ads perfomance depends of google internal stats...
Yes I know for a fact it does - the history of your adsense account does matter The effect however should not last longer than around 1 month. So give it some time and it will go back to normal
