The three Amazon ad formats in India
Sponsored Products are the workhorse: your product appears in search results and on product pages, and you pay per click. They work for almost every category and are where every seller should start.
Sponsored Brands show your logo, a headline and multiple products at the top of search results. They require brand registry and suit sellers building a brand rather than moving a single SKU. Sponsored Display lets you retarget shoppers who viewed your product or similar products, on and off Amazon.
