TikTok Post Purchase Survey - Custom Question Best Practices

The TikTok Post Purchase Survey (TTPS) comes with 2 standard attribution questions, but you have the option to add a 3rd custom question to gather additional insights about your customers. This guide will help you understand the available question types and provide recommendations for the most effective questions to ask.

Ready to make the most of your custom question? Let's explore your options!

You can add or edit your custom question directly from the survey design builder during the TTPS setup process.

To create a new custom question, click "Add Custom Question" in the survey builder. This will open a modal where you can configure your question type, write your question prompt, and add response options.

To edit an existing custom question, select “Edit Survey” from the dashboard. Once in the survey builder click "Edit Custom Question". The same modal will open, allowing you to modify your question settings.

NOTE: For meaningful insights, avoid changing the survey type or prompt for 14 days. Editing a custom question resets collected responses and removes past data.

When adding your 3rd custom question, you can choose from three question types:

Radio button questions are single-response questions. Customers will only be able to select one option from your list. Use this when you want customers to choose their top answer.

Checkbox questions are multiple-choice. Customers will be able to select more than one option. Use this when multiple answers may apply to a single customer.

Text input questions allow customers to type a free-form response. Use this when you want open-ended feedback or information that can't be captured in predefined options.

Here are a few of the most commonly used custom questions for the TikTok Post Purchase Survey, along with what each question helps you understand:

How long did you know about us before making your first purchase? This question reveals your customer consideration period and helps you understand the typical journey from awareness to conversion. Shorter timeframes may indicate strong product-market fit or effective remarketing, while longer periods suggest customers need more time to evaluate your brand.
