DefinitionA/B testing
Datalayer
A data structure used to transmit information between a website and a tag management tool.
JavaScript structure that allows data (page, user, behavior…) to be transmitted to marketing tools like AB Tasty or Dynamic Yield to target tests or personalized experiences.
- 👉 In AB Tasty, dataLayer variables can be used directly in the targeting interface, without additional code. For example, you can target a "product" type page or a CRM segment like "VIP" by simply selecting the variable in the rules engine.
- 👉 In Dynamic Yield, this is typically done through custom evaluators: small JavaScript scripts that allow you to extract or interpret the value from the dataLayer (or other sources) to build a more flexible targeting rule. Example: reading a
userTiervariable to target only "gold" users.
