Dynamic Yield

Dynamic Yield, owned by Mastercard, is a personalization platform used by large retailers, grocers and restaurant chains. It decides what each visitor sees in a given slot on a page, such as a hero banner, a product carousel or an offer, based on segments, behavior and tests that run in the background.

Teams use it to set rules ("show returning shoppers their last viewed category") and to let its algorithms pick the best-performing variation for each audience. It also runs A/B tests and product recommendations, so many stores use it in place of separate tools for each job.

This is an enterprise product. It works best with clean product data and a team that can plan campaigns and read test results every week. Ask how it connects to your commerce platform and customer data, and how much of the setup the vendor or a partner will handle.
