Bit late with this one, it actually came out a yesterday. Or the day before. I’ve been busy.

Anyway, as you probably already know Google have launched a cool ad diagnostic tool at adgroup level that sits next to individual keywords in the form of a magnifying glass icon.

Rustybrick over at the SEroundtable has a nice little picture that I have stolen borrowed.

The ad diagnostic tool basically checks to see why an advert may not be running and gives you some tips on what you can do to get it up and running.

The Google Adwords help center explains all.
