I've had an account that I may have been making too many changes. This is for a plumbing campaign where there is a LOT of rubbish/non converting keywords. The search terms now I have are brilliant but I'm getting hardly any clicks and impressions. Just yesterday we only had 63 impressions ($200/day ad budget) and no clicks. Had a look at the search impression share and we had 50% of the search impression share? Does this mean we ran out of impressions to even show or have I not been patient enough and let Google do its thing..
