what the hell with this ?

55 impression but 7 clicks $0.74

is this normal ?
if not what i should do ?

i normally got less than 1% ctr per day

 

With that low of impressions it can be legit. Always safe than sorry though.

 

i got average 2000 impressions per day
now this CTR make me scared...

 

I think Google has changed way how they count impressions. I have two ad boxes on my site and they show very different statistic.
One shows 180 impressions and other shows 60 impressions. Both boxes are placed one after other and both are very visible.
Maybe this is something new from Google?

 

Wait until the stats update, maybe it will get closer to normal.

 

i will suggest you to bring more organic traffic
