Clicks but no revenue?

[halbesma]

Hi, I have one web site out of my couple that have Adsense on them and for the past 3 days there have been clicks but no revenue from those clicks (I am using the URL channel).
Yesterday, of the 220 (approx) impressions - i have had about half a dozen clicks with no eCPM or Earnings. This has been consistant for the past 3 days.
Why would this be?
I have never seen PSA ads on my site, the ads are only on about 6 pages of my site.
Can anyone help?

Looks like Google treats those clicks as invalid for some reason. Ask Google.

I see exactly the same.
It is strange. My CTR has droped 60 percent.

It usulally looks like that if if a click is invalid.

"1" click / "0" eCPM / "0" Earnings

but now most of my channels show

"0" click / "something" eCPM / "0" Earnings

The channels normally does not show up if there were not a click.
And why do i get an eCPM?

I doubt that they are invalid clicks.

You may not see PSAs, but a visitor from another country may.
