Clicks Without Impressions?

Has anyone seen this before?

I unpaused a campaign and checked on it about an hour later and noticed that one of the ad groups had 5 clicks but no recorded impressions.

Should I be concerned about this?

 

Probably not - it's most likely either a time-lag thing, or someone clicking on a cached page.

 

I created an adgroup for a keyword noone would search so i can test click count. i searched google for it a few times, about 5 times, to get its impressions recorded. then i clicked once on my ad.

sure enough, the 1 click got recorded but with 0 impressions. dont they count an impression to be an instance the ad is shown? so like if i refresh, and the ad shows 10 times on my cpu, it will accrue 10 impressions right?

 

It's a time lag, I had the same thing today. Later on in the day the impressions caught up.

 

Clicks are updated every hour or so, and impressions can take up to three hours to be updated.

 

Amazing story HAHA

 

That's really weird you may start to check if things get little dubious.
Good luck
