The nastygal google ads are pointing to http://localhost/error.html
Is this common? They are out of ad money and Google will not charge if pointed to localhost?
Google charges regardless of URL. This is just a mistake.
My experience has been that Google rejects ads that don't have a valid URL. We got all kinds of warnings about potentially having our Adwords account banned if we didn't fix a typo in a URL in one of our ads.
