CPC Varies Drastically

Friday had one more click than Thursday.
Yet Thursday's earnings are 4.4 times of Friday's.

How can this happen? Were the advertisers' budgets used up? I'm quite intrigued.

Do you get a good few thousand page views daily? Because if not your sample is too small to get meaningful data really.

I do, but over 15 / 20 small sites. Every day each one is drastically different in epc / click through, etc. Alone its meaningless. Added together, the stats are amazingly constant.

I get about 2500-3500 impressions daily. Does that make a difference?

And how many clicks?

[romanov]

The two days had 19 and 20 clicks.

As Nitrous said, the sample is too low to make questions.
You probably had a high paying ad clicked a few times at Thursady.

I get about 500 clicks a day, and even that varies quite a bit (around 20 percent)
