I'm still rockin it like I have been... I'm almost 100% sure they have a quality score because of what I've seen with some other accounts I manage. I had one account which wouldn't get hardly any impressions on ads, and I had to pay double or triple to even get a little.
I duplicated one of my ads, but it went to a different site for the redirect to the same offer. The only difference would be the domain and the fact that my site is a little mini site with 4 or 5 pages of unique content, privacy policy, contact, etc... and hers wasn't. It got about 4k impressions, with a .08 ctr (same as my ad) before it just died I would've lost money for sure if I raised my bid any more.
Back on my account, I've created a few new ads running the same offer and copy but with different pics. They still run great, but the ctr is lower (bad pics probably).
