The product match score indicates how well a given product matches a customer's preferences based on their quiz answers.
By default, it has an x/y format where y is the number of questions in the quiz, and x is the number of times that product was a match for the chosen answer. You can change this format to a % or hide it completely using the Match Score Format settings.
The more present a product is as a match to the selected answers the higher its score will be.
The tolerance slider allows you to set a match score threshold for product recommendations. Set the slider to your desired percentage, and only products that align with quiz answers to that extent will be suggested.
Excluded products become useful in scenarios where if a particular answer is selected, then certain products should absolutely not be included in the final results.
If you exclude a product from an answer, and that answer is selected, the product will not be included in the results regardless of the match score it accrued throughout the quiz.
Being excluded from specific answers doesn't exclude a product from the quiz entirely and it does not impact its final match score. The product can be set as a matched result to any other answer in your quiz and it will still be included in the results based on its match score if that particular answer isn’t selected.
