Today (2014-10-20) I noticed that on one website of mine I got two adsense clicks without any page views. How is this possible? And should I worry about violating adsense policies?
This question is very similar but also quite different: How can I have more clicks than page views in AdSense. The answers don't apply at all if there are no page views at all (i.e. right clicking, a user clicking more than one ad).
Here's a screenshot I just took:
Update: It's still 0 and 2 a day later. Meanwhile I'm seeing it also on another website today, with 1 click for 0 page views.
Update 2015-01-29: I saw 1 click and no page views, in the afternoon. Half an hour later it indicated 2 page views. I guess adsense might show clicks before page views in some cases.
