What is A+ Content?
A+ Content (formerly Enhanced Brand Content) allows you to add rich images, comparison charts, and brand stories to your Amazon book detail page. It increases conversion rates by up to 10%.
Do I need a trademark?
No! Authors used to need a trademark, but now KDP allows any self-published author to create A+ Content for free.
