0 impressions, 1 click. How does that work?

Started a new campaign yesterday. Today it's showing that one of the keywords had 0 impressions and 1 click.

:scratching my head:

If from yesterday, not sure but if from today clicks and impressions are not always updated in sync. Check it in a few hours.

Never noticed it before though. Never mind. Thanks for your reply.

I see that once in a while. Not uncommon. I think it could be if someone clicks at the turn over point.or has the impression in cache.

I've always wondered if using the back button like Google suggests eliminates an impression but will still register a click...
