I don't think that many users clear their coockies.
No they don't clear their cookies, but if the users are new visitors to that specific page where you saw the ads repeated on, the users most likely won't see the same repeated ads across all units you've seen as Google hasn't cookied those users yet. They'll probably see different ads too due to IBA.
I said to clear your cookies for you to see new ads. It appears you have visited that specific page more than once. "Clearing cookies" is the same as "new visitor to that specific page" in this case. Try using a proxy to see if you see the same ads.
My earnings are up on the sites that gained traffic in Panda. If it is true that Google knocked down the sites with over zealous ad usage, does less ad inventory space = higher prices per click? Sorry for you Adwords folks, but I hope so.
My biggest site had its lowest-ever click day, apart from Xmas, by a considerable margin down almost 33% on average, even more if compared to a normal weekday, CTR just over -30%, eCPM -28%, actual earnings -26.7%, easily my worst earnings' day since the first week of February!
Things are definately NOT RIGHT. Today is as "strange" as yesterday. How can everything be so low, with "human" traffic so high? I was expecting a click dump from yesterday that never came for two days now? It's as if Google isn't counting any clicks, just impressions. I received only FOUR of the lowest paying clicks in TWO DAYS, and impressions are almost double the usual amount!
This is bizarre, I ended up with an excellent Saturday's earnings.
Actual clicks were -22% however my EPC was +31% giving me +10% on the day.
Did I get some unaccounted for credits on my biggest site that were lost on Friday going from its worst day of the month to its best? Combining the two days metrics show clicks -15% yet earnings are are within USD 0.25 of the daily average!
Interestingly last Saturday is now its second best day of the month so far.
