On 25.07.2015, my earning by Adsense was $1.34 with total 185 page view and 602 impression. There are 16 clicks count. I got a strange think that $0.29 came from one viewer from POLAND, analytic showed that there is 0 page view...0 impression....09 clicks and no information page RPM...Impression RPM. I do not understand that how 09 clicks possible with any page view? Is it an abnormal earning? Should inform to Adsense?
Its not strange, You will notice changes in your finalized earnings of every month. Looks like bot traffic to me.
