I've been using Adwords for about four years, and Google's always been happy to take my money.
Last year I started working on a new site, one that would replace the ecommerce section of my current main site. It was the same products, so I used the same pages, but with the new graphics for the new site.
Recognizing that this was duplicate content, I no-indexed, no-followed the entire new site, until I could figure out where I was going with it.
Last night I went to check on the day's activity, and saw that Google had suspended the account because of "Mirroring".
If a whole site is noindex, nofollow, can it be a mirror?
I don't get what's going on at all, and Google is as usual not being specific enough for me to address the problem.
Question: did you just replace the domain/URL in your ads or did your re-create the campaigns and groups with the new domain/URL? If the former, you cannot promote more than one domain in the same group.
