Simon,
Well thank you very much for your review. Your campaign is indeed doing quite well. I have noticed most campaigns have been doing better lately CTR ranges from 0.3% to 1.2%. The minimum I've seen was 0.1% CTR and when that happens, I usually advice companies to try a new banner, which solves the "bug".
Simon, the "sponsor box" idea intrigues me, but what is that exactly?
Again, thank you for what looks to be the first review of HD advertising. Its always good to start with a positive one.
Best,
