When I look at my report and see the "effective CPM" I wonder how much I can/should generalize based on that.
If I have N thousand pageviews somewhere and my "effective CPM" is $10, is it reasonable to assume my actual take would be $10 x N?
Also, $10 seems very high to me (in a few days and with very little traffic on the AdSensed pages this has varied from $2 to $10). Does anyone have a sense of what is more or less normal for "effective CPM?"
I'm new to AdSense so I don't have a report history I can look back on to figure this out, so I'm hoping some of you can share your experience.
Thanks.
CPM = (earnings divided by page impressions) x 1,000
...in a few days and with very little traffic on the AdSensed pages...
With a short history you really can't forcast earnings.
And with low traffic pages the eCPM can sometimes fluctuate a great deal. It can be very high one day and zero the next day. CTR on these pages can do the same thing, at least from my experience.
You just need to wait for a longer history to develop before coming to any conclusions.
On low traffic pages I'm more inclined to look at the earnings per click and the CTR before I make any changes.
Those will show up pretty quickly, but I generally let them run a week or so unless those two numbers change dramatically.
On higher traffic (for me) I like to get somewhere between 3,000 and 10,000 impressions before drawing conclusions, sometimes a lot more. But on low traffic pages (again, for me) that could take a very long time.
The other side of this is that relatively low traffic pages that attract a high CPC and CTR can sometimes yeild a significant part of your income.
