That said, not all conversion events naturally fall under either the addToCart or purchase subtype. For example, if you send a conversion event for an action like “Add to Wishlist”, this event does not belong to either standard subtype. In these cases, you can safely ignore the “No Event SubType” warning displayed in the dashboard.
When a conversion event does support a subtype, providing it helps the model distinguish between different levels of user intent and contributes significantly stronger signals, leading to more effective personalization.
While Advanced Personalization will still function without subtypes, an event setup with subtypes produces more meaningful results. The stronger the signals you provide, the stronger and more accurate the personalization effect will be.
