Monday I had 37%+ more clicks than Sunday and earned a Dollar more!
The ads look the same from here however it was noticeable all day yesterday for me that the EPCs were much lower than average therefore it was not just one region.
Did anyone else see a similar drop in EPC yesterday?
However, today is dire... 28c for 5 hours.
AdSense is like the weather, IMHO: Some days are warmer or cooler than others are, but long-term variations are less extreme than what you see from day to day.
Also the lowest EPC's for a long time, years.
Net result?
Lowest earning days for a long time.
FWIW and YMMV
It has been consistently growing from 1 year or so and I would hate it to see the overall revenue being lesser compared to previous month :-)
Wouldn't it be nice if there was a matching correlation between high Impressions and high CPM? Too often it seems like an inverse relationship: the higher the number of impressions, the lower the CPM.
The inverse relationship makes a lot of sense. Let's say there's a pool of 10,000 clicks for "pink widgets" on a given day. Now let's assume that those clicks are being allocated to a long list of pages on different sites about "pink widgets," using some kind of formula that takes historic demand into account. One day, your page about pink widgets has twice its normal traffic. Where are the extra clicks for "pink widgets" ads (and impressions for "pink widgets" ads that result in clicks) going to come from? Does it make sense for Google to allocate more impressions and clicks to your "pink widgets" page at the expense of other sites and pages?

Wait - I always thought that maybe ads or ad views may be allocated. If you are saying now that CLICKS are allocated, what exactly does that mean?
Does it mean that Google actually assigns a maximum number of (paying) clicks to a given page? Or do they assign an estimated maximum payout to a given page? If so, this would explain why some people see revenues almost disconnected from actual click behaviour. (On our site, for example, we had the best day of 2008 on a day with a severe server outage, resulting in less ads being displayed, and obviously less clicks.)
The inverse relationship makes a lot of sense.
Whilst I know what you're saying the fact is for me that Monday's EPC was low all day no matter from which region people were clicking, Tuesday's clicks were normal and the EPC went back to normal.
Why is it that it IS possible to have an absolutely diabolical day, in comparison to average, yet not have an absolutely stellar day, again in comparison to average.
It seems to be almost pointless sometimes...note I haven't mentioned ceiling...ooops:-)

It means allocating impressions based on anticipated clickthrough rates. IMHO, that's a more efficient and productive approach than simple allocation of impressions, because different sites or pages have different CTRs.
