Prime Day 2021: Amazon Performance Analysis

According to NBC, “Prime Day sales have historically surpassed those on Black Friday and Cyber Monday”, making Prime Day the largest shopping event of the year. With Prime Day 2021 come and gone, we’re taking a look at the numbers.

Overall, our brand partners performed well and have consistently seen the value in optimizing their strategy to make the most of Prime Day. Below are some preliminary results that give further proof into the success of brands who participate in the event.

Search & Advertising Recap

Here at Macarta, we’re thankful to lean on the expertise of our team. We checked in with Rene Crandall, our Search Marketing Manager, for some post-Prime Day insights:

“Overall, performance this year from a search and advertising perspective were pretty typical of the usual Prime Day bump. Bids were more expensive (as they are year after year), so ramping up KW bids and budgets before Prime Day is more critical than ever.

It’s also worth noting that brand partners who ran discounts performed much better than brands who didn’t run discounts, which shows that success is largely based on offering price discounts. Some brands also saw more ad-attributed sales on Day 2 of the event vs. Day 1 (and vice versa) — that inconsistency means that it’s important to be aggressive and competitive with advertising on both days.”
