AdMob clicks / requests ratio?

Hello guys,

I see there are almost 1000,000 ad requests now in my app with almost 400,000 of impressions and just 7 clicks, all of which happened on one day. I have never had clicks before or since.

I have a funny feeling this isn’t normal. Could you share your experience, please? [import]uid: 52103 topic_id: 16828 reply_id: 316828[/import]
