Ads appearing in UK but not US

[JonnyWales]

Yesterday I added a new Ad Group to an existing campaign and am getting unexpected behaviour. The ads from the new group are appearing on google.co.uk but not google.com. I have not changed any of the campaign settings which means they should appear on both. Ads from the other groups do indeed appear on both. Any ideas?

Is the competition higher on .com and your ads are on the 2nd page.

Are you advertising for a site that has multiple advertisers bidding on the domain, thus they're being shown instead of you?

Is your daily budget being used for .co.uk, so the U.S. syndication isn't necessary to fulfill your budget?

Have you broken your campaigns in half - one for US and one for UK so you're positive your ads aren't getting impressions in the US?

The only thing I can add to this, is that it's at least possible that the answer may lie with what you're advertising in the new Ad Group.

I'd suggest contacting AdWords support and having them take a look.
