I discovered my ads aren't showing. I used the Ads Diagnostic Tool and it told me that my keywords weren't showing because "Your campaign has reached and exceeded its monthly budget. "

I already have my budgeet limits set high and they have been working at the current levels for months. I even tryed spiking one up to $500 and it's still not working. Any ideas what this might be?

The only thing you can probably do is contact Google about it. If your budgets higher then your spending, it should keep serving your ads. I know I keep mine at least 2 or 3 times or more what my actual spending or projected spending is to make sure they don't slow my ads...

Yup, try contacting google. By right, it should work. Do let us know the updates on the issue.

I'd check to see if there are any balances oweing, that you have forgot to pay. My CC had recently expired, and they stopped showing my ads. I found out later after my ads stopped showing that they had paused all my campaigns

i do not personally consider google ads a good way of site popularization
