Does anyone have any experience with Amazon's advertising campaigns? Do they work? Which type is the best? And I've just read on another thread that these campaigns do not apply to the UK. Is this true? Thank you. Lyn.
Search for "AMS advertising" and you'll get plenty of information.
They work for me; all my campaigns are profitable. However, it takes a lot of optimization, and they're not nearly as profitable as they were a year ago. And yes, they're only available on the US (dot-com) site, unless you have a UK publishing account.
