Amazon finally fixed the biggest issue with AMC audiences for Sponsored Ads.
You can now add up to 10 audiences to a single Sponsored Products campaign.
Until now, it was one audience per campaign.
Want to test 6 audiences? That meant building 6 campaigns. Same targets, same budgets, 6 times the management.
So most of us tested two or three audiences and stopped. Scaling was very, very hard.
Now you can put them all in one campaign and compare them side by side.
But there's one thing I still can't figure out 👇
What happens when audiences overlap?
Say a shopper is in both:
✅ High interest audience at +50%
✅ Viewed your product page at +80%
Does Amazon apply the highest one?
Stack them?
Or use some kind of blend?
I haven't found anything from Amazon that answers this yet.
My guess is it takes the highest, but I'd rather test it than assume.
