# How to Use The Master Question Feature to Enhance Product Recommendations

## **Introduction**

The **Master Question** feature in Quizell allows you to prioritize a specific quiz question within your product recommendation logic. By designating one question as the *Master Question*, its answer becomes a key decision-maker in determining which products are shown to quiz takers.

This is especially useful when one answer is critical for product relevance — such as gender, allergies, or core preferences. In this guide, you’ll learn how to set up the Master Question feature and use it strategically to improve the accuracy of your quiz results.

## **Step-by-Step Setup Guide**

### **Step 1: Identify the Most Important Question**

Start by reviewing your quiz and identifying the question that has the biggest impact on product eligibility.

A good Master Question usually:

* Eliminates entire product categories when answered
* Prevents irrelevant or incompatible recommendations
* Acts as a “hard requirement” for product matching

Once identified, this question is a strong candidate to become your Master Question.

### **Step 2: Set a Question as the Master Question**

To activate the Master Question feature:

1. Open the quiz you want to edit.
2. Select the question you want to prioritize.
3. In the left-hand panel, toggle **Master Question** on.
4. Click **Save** to apply your changes.

The selected question will now have priority in the product recommendation algorithm.

## **Best Practices for Using Master Questions**

* **Use Only One Master Question**
In most cases, assigning a single Master Question per quiz delivers the best results. Multiple Master Questions can make recommendations too restrictive.

* **Avoid Over-Filtering**
If your product catalog is small, be cautious — using a Master Question may lead to fewer (or no) results.

* **Choose High-Impact Questions Only**
Reserve this feature for questions that truly define product compatibility.

* **Monitor Quiz Performance**
Regularly review quiz outcomes to ensure the Master Question improves relevance without reducing conversions.

* **Refine Based on Feedback**
Customer behavior and feedback can help you decide whether the right question is being prioritized.

## **Examples of Effective Master Questions**

* **Gender-Based Questions**
Ideal for apparel, grooming, or personal care quizzes to avoid mismatched recommendations.

* **Allergy or Sensitivity Questions**
Critical for food, supplements, or skincare quizzes to prevent unsuitable product suggestions.

These questions act as essential filters and significantly improve recommendation accuracy.

💡 **Tip:** To ensure answers are properly linked to products, make sure your product mappings are correctly configured in Product Match.
