AB Tasty: Complete Guide to A/B Testing and Personalization

Dynamic Yield is an enterprise personalization platform founded in Israel in 2011 and acquired by McDonald's in 2019 — a use case that popularized the tool beyond eCommerce. In 2022, Mastercard acquired Dynamic Yield to integrate its personalization capabilities into its network of data services for retailers.
Its value proposition centers on omnichannel personalization: the same platform manages the experience across web, mobile app, email, kiosks and any digital touchpoint. For retailers with a multi-channel presence, this eliminates the need for multiple personalization tools with fragmented data.
Personalization is one of the highest-impact levers in CRO. Adapting the experience to the user's context — prior behavior, segment, traffic source — can significantly increase conversion rate without needing to grow traffic.
Dynamic Yield includes a product recommendation engine with multiple configurable strategies: bestsellers, frequently bought together, based on browsing history, similar to current product, or hybrid models combining manual rules with machine learning. Recommendations can appear on product pages, listings, cart, checkout and email.
The key differentiator is the ability to directly A/B test recommendation algorithms, measuring actual revenue-per-visitor impact before making decisions.
Beyond product recommendations, Dynamic Yield allows personalizing any page element: banners, headlines, offers, section order, CTAs. Personalization can be based on category affinity, prior purchase behavior, RFM (recency, frequency, monetary), external CRM data or real-time signals such as weather or time of day.
Dynamic Yield includes a triggered email module with dynamic personalization at the moment of opening. This means email content is rendered when the user opens it, not when it is sent, allowing inclusion of updated prices, real stock levels or recommendations based on the most recent behavior. Typical triggers include cart abandonment, browse abandonment and re-engagement of inactive users.
The platform includes A/B testing and multivariate testing as a native component. This allows validating not just design elements, but also complete personalization strategies: which recommendation algorithm converts best for a specific segment.

Bloomreach competes directly in the enterprise segment and adds a search and merchandising engine that Dynamic Yield does not natively cover. Nosto is more accessible for the mid-market and more focused on pure eCommerce. If the budget does not justify Dynamic Yield, PostHog covers behavioral analytics and A/B testing at a radically lower cost for growth-stage projects.
Homepage personalization by user segment. A new visitor sees a homepage oriented to presenting the brand and its most popular collections. A returning customer with a purchase history in a specific category sees recommendations and promotions aligned with their profile. This differentiation has a direct impact on eCommerce conversion rate improvement.
Category page and PDP optimization. Product order in the listing, highlighted attributes on the PDP and cross-sell recommendations in the cart are variables that Dynamic Yield allows testing and personalizing systematically.
Abandonment recovery. Triggered cart abandonment emails with personalized content (the exact product they abandoned, updated price, related recommendations) have significantly higher open rates and conversion than generic emails.
A CRO audit before implementing Dynamic Yield helps identify which segments have the greatest personalization potential and which strategies to prioritize in the implementation.
Dynamic Yield is implemented via a JavaScript snippet similar to other personalization tools. For deeper integrations — server-side personalization, OMS or CRM integration — it offers REST APIs and webhooks.
Typical onboarding includes configuring the product catalog, defining tracking events (product view, add-to-cart, purchase) and creating the first personalization campaigns. Time to first active campaigns ranges from 4 to 8 weeks depending on integration complexity.
To leverage personalization capabilities in checkout, coordination with the eCommerce platform's development team is required.
Dynamic Yield is an enterprise personalization platform with mature omnichannel capabilities, especially powerful for product recommendations and triggered emails. Its integration with the Mastercard ecosystem adds a layer of transactional data that few platforms can offer.
Its complexity and cost place it in the segment of large retailers with established operations. For growth-stage companies, more accessible alternatives exist that allow the same personalization journey to be undertaken progressively.
