So I wake up to 188 page views and one click with a CPC that's over $4. Great!
2 hours go by and no more clicks and no more page views, even though the logs show that Google Media Partners is hitting the site as much as it ever does. Ads are showing just fine. This goes on for about 3 hours and then the page views start increasing again and the CPM ads start adding some pennies to the earnings. I figure during those 2 hours, Google under-reported page views by at least 200 and who knows how long before that.
If they are lying about page views, what else are they lying about?
My entire CTR has gone done to 1/10th of previous months, first by clawbacks, then by clicks. I'll bet I'm still getting 10x the clicks that they are reporting.
More and more, the evidence points to Google artificially limiting revenue to publishers. Since I started, I've noticed that CTR varies inversely to CPC. If I get some high value clicks, CTR goes down, and vice versa. Not every day (normal variation I suppose is allowed to have some effect), but more days than not. Whether they do it by serving poor performing ads to publishers that their algorithms don't like, or actually lie (as in the case above), or some combination, I don't know.
I'd like to see some independent group set up disposable sites and have teams of users clicking on ads and buying things to compare what Google reports and what is known to have happened.
