For the past six months, I've run a small campaign for "Find (brand name widget) repair". These ads have been approved with no difficulties. Recently I started a new campaign with near-identical ads, and those ads are "Approved (Limited)" and the keywords are receiving no impressions (the serving status is "No").
Dozens of other advertisers are advertising with this term (as I am in a different campaign in the same account). I tried making some insignificant changes to re-trigger the approval, and the status came back the same.
Any ideas on what I can do to get this ad running?
The best is to check with Google. Ask specifically about those that are "limited".
If you point to other folks, you'll probably get canned reply about how they have the allowance. You already know they don't.
You have to be persistent.
I'll try an ad that is completely identical to the existing "Approved" ad, but in a different campaign, and see if that works. Only the destination URL will change (national widget repair vs. cityname widget repair).
