# Linking Once you have created your questions and added your products, you have to link question answers to products so products can be recommended (*Step 3 -* *Linking):* ![](/files/-MFaLmSecBUnJ8ouH275) In this step, you will have to link each answer to their matching products. The [linking panel](/create/linking/linking-answers-to-products.md) is the easiest way to connect your questions with products. This method is suitable in a wide number of cases. However, PickZen provides two alternatives: * [**Decision tree**](https://help.pickzen.com/create/creating-questions/branching-logic/branching-controlled-by-tree): In this case, you would assign products to end nodes (outcomes). Since this method is best for specific use cases, check out the [Branching controlled by tree article](https://help.pickzen.com/create/creating-questions/branching-logic/branching-controlled-by-tree) for more information. * [**No-Code**](https://help.pickzen.com/guides/nocode): This mode is recommended if you need fully tailored recommendations with the possibility of providing calculations, ideal for cosmetics, and nutritional products. Check out the [No-Code documentation](https://help.pickzen.com/guides/nocode) for more information. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
