How to Use Dynamic Quizzes
Use a key question to create your product pool, and non-key questions to rank recomendations.

Dynamic quiz logic is built using key questions, which are the questions that add or subtract products from the quiz's final recommendations.

Turning on a key question is as simple as selecting an option, but making sure it works with the quiz you're building can involve a little more than that.

What you'll learn

How dynamic quiz logic works to filter customers to the right answer, and what key questions do.


You'll just need to have a dynamic quiz with at least 1 multiple or picture choice question.

All Octane AI quizzes are dynamic quizzes at creation.

Picking your key questions

Here are some general best practices to follow when picking key questions:

  1. Start with just 1-2 key questions.

  2. Pick a question all customers will answer.

  3. Questions about core customer concerns are great choices.

  4. Carefully consider your quiz logic before choosing a multiple select question.

For example, in a skincare quiz you may want to choose one of the following questions to make your key question:

  • What is your skin type?

  • What are your skin concerns?

Having too many key questions can create a dead end for customers if the answers aren't creating product matches.

Adding dynamic products

Each answer in a dynamic quiz can have products included or excluded.

Inclusions have to match between key questions.

If answers from different key questions don't share any products in common, customers will land on the fallback result page instead.

Ranking recommendations with non-key questions

Even though non-key questions won't add or remove products from a recommendations, they can be used to rank how those products are shown.

When a customer picks an inclusion inside a non-key question, the products inside will be ranked higher.

An exclusion will rank products lower in non-key questions.

Non-key questions will have no effect however if the products inside of them aren't also inside of the key questions.

How do variants work with inclusions & exclusions?

You can add individual variants, or the whole product into an answer.

At the end of a quiz, the variant dropdown menu will only display the variants that match your quiz answers.

Using multiple select questions

Multiple select questions (questions where customers can select more than 1 choice) can be a complex addition to quiz logic.

Before choosing a multiple select question as a key question, carefully consider:

  • How many answer combinations between your key questions will the multiple select question create?

  • Can this question work with an answer selection limit or without multiple select?

  • Would some products work better inside of a dynamic block (advanced logic on Octane Plus required)?

Multiple select questions can create a more complex quiz than you may actually need.

Frequently asked questions


Do non-key questions have to have products in them?

Non-key questions don't need to include products. Questions can also be used to gather data, segment customers or just for quiz vibe.

Why aren't I getting any results?

If the combination of answers chosen in key questions don't have any products in common, there won't be any products to recommend.

When this happens, customers will see the fallback result page instead.

Why is my exclusion not working?

Exclusions need to be in a key question in order to prevent a product from showing up.

What if my quiz has no key questions?

If a quiz has no key questions, the quiz will simply add products from every answer chosen to the result.
