Every Gloriads blog article tagged Targeting.

Amazon Sponsored Display targets pages or people, never keywords: products and categories, remarketing and Amazon audiences, or Amazon's own choice.

Amazon Sponsored Display retargeting shows your ad to shoppers who viewed (up to 90 days) or bought (up to 365 days) products you pick, on and off Amazon.

Amazon Sponsored Products are pay-per-click ads for one product, shown in search results and on product pages. Where they appear, cost, who can run them.

Negative keywords stop your Amazon ad on searches you don't want: negative exact, negative phrase and negative products. Limits, delays, how to pick them.

Automatic targeting lets Amazon pick where your Sponsored Products ad shows; manual lets you choose keywords or products. When to use each, or both.

Amazon Sponsored Display, now called Display, shows your products to shoppers on and off Amazon by interest or product page, paid per click or per view.

Amazon keyword match types decide which searches trigger your ad: broad for related searches, phrase if the search contains it, exact for the keyword.
Gloriads runs your Amazon Ads by rules you control, on all four ad types.
