Welcome to WebmasterWorld Guest from 220.127.116.11
I'm seeing a 50% decrease across a few sites for the same volume and was curious what others are seeing for earnings. All sites do over 150k page views a day and up.
Also, November was 10% less than October, and December was the same as november.
I think Google as lowered the payout ratio in preparation for their IPO. It will look good to have more profit on their books.
There are many, many factors that determine impressions, CTR, EPC, effective CPM, and bottom-line revenues. Individual examples or case histories are always interesting, but we shouldn't make broad assumptions based on limited samples.
Very true, I was probably a bit hasty in my statement. I realised later that my adding new sites in slightly different topics probably affected average EPC as advertisers pay widly different rates in different sectors (and different countries in the same sectors).
Roll on detailed stats to help elimiate some of this guesswork and speculation.
