Long time lurker at other place.
I've not had much luck with BB ads in the past, especially with CPM -- it just seems to suck up money with no discernible results (clicks or sales). My CPC ads seem to only get served for short periods of time. I've always assumed it was because the creative wasn't good enough. Here are a few I'm trying out next week on a 5-day free run for a two-book bundle. Do they seem "clickable" enough?
I've mixed and matched the images and text but didn't want to put every version out here. Which (if any) do you think would work?
Here are the results after a 5-day free run. I bid 0.50 per click on everything and refused to raise it for any reason. There were three versions of each ad and all pointed to Amazon's US, UK, CA and AU stores.
Ad 1 (3D Cover image) got 27 clicks @ 0.50 for CTR of .55
Ad 2 (Sci Fantasy Adventure) got 169 clicks @ 0.27 for CTR of 4.03 (164 of those clicks were in AU store and someone bought the whole series on the first day, which was cool. Don't normally sell much in AU). Didn't think this creative would be the performer--just goes to show, you never know.
Ad 3 (Brassy one) got 7 clicks @50 cents for a 0.33 CTR
I definitely got more bang for the buck from my Facebook ads (much lower click prices and many more clicks converting at about 66% each).
I'll probably revisit BB ads once I go wide on this series next year to focus on non-U.S, non-Amazon stores. I'd be interested in hearing of people's experiences with those.
