Is PPC the Best Way to Optimize Your Amazon Ads?

Bid management is the number one first lever you should be looking at pulling when you're focusing on optimization. conversion rate super important in my opinion, because it actually shows you the amount of people that land on your page and buy your product. If I have more than 20 different products in the same category and the same search term, should I run PPC for all the products? This one's always a question I go back and forth on. It also depends on your brain goals.
