Amazon PPC glossary
Placement
Placement is where on Amazon your ad appears, such as the top of the search results or on a product page. Different placements can perform very differently for the same keyword, which is why Amazon gives you a report on them.
Example
Your ad at the top of search converts at 12%, while the same ad deep in the search results converts at 4%. Seeing that difference lets you decide where the money is best spent.
Where it matters most: Book 1, The Amazon PPC Clarity Guide, in the chapter “Bid Optimization.”
