I just checked my adsense account. I was surprised to see that I got 3 clicks upon fewer (<=5) impressions since starting of the new day, which caused eCPM extremely high. i just wonder if it is that somebody tries to attack my adsense account, or this is just a normal traffic and eCPM will go normal when more impressions are recorded after the whole day. I look forward to your reply. Thanks!
dont worry about it you find this sometimes happens , sometimes it evens itself out over the day or sometimes it was just due to comeone clicking a number of links for infomation.
