What is products recommendation logic?
Option 1: Recommend products based on specific combinations of answers
For this option, you manually associate a set of questions to products that are recommended on the Results page. From the "Choose products" page you'll set Answer paths by answering your quiz as a user would and then choosing what product to show for that particular set of questions. More info on how to configure your quiz using answer paths.
Option 2: Recommend products with each answer a user chooses
Instead of choosing Answer paths, you'll simply associate questions with products on the Question page. The Results page will show a recommended products for each answer the use chooses. If your quiz has 5 questions, your quiz will likely recommend 5 products, one for each answer the user chooses. In this scenario, the combination of particular sets of answers is disregarded.
