I set up a new ad as part of a campaign last week. Due to the nature of the site it had to wait for review. I checked a few days later using the diagnostic tool and discovered that the ad had been disallowed. I accepted the reasons given, unfortunately I did not bother to delete the ad. I have just checked the campaign and have found that the ad has had 25 impressions and a click this week. When I use the diagnostic tool this week to test keywords used in the ad it states that I do not have any ads matching those keywords. How am I getting clicks and impressions recorded for an ad that doesn't exist?
No, I've got the content option turned off. It's only get about 10 or 15 impressions a day compared to 100s on the other adgroups. I guess it is just a glitch in the system. The ad was set up to target an event in London this weekend, so I'll delete it now and solve the problem that way!
A quick note into AdWords support could solve this one pretty easily, but I'll give you a couple of high level guesses as well.
#1 there are keywords in the Ad Group which by themselves do not require review before they run, so they are active while the bulk of your terms await the editorial review. If 'widgets boom' requires review, it does not prevent your ad from being displayed on 'widgets pop'.
#2 there is also a small chance that for some reason one or two terms have been reviewed, while the rest remain unchecked. Unlikely, with the way our review system works, but anything can happen.
