What is a post-purchase survey and which questions should you ask?

Published

Short answer

A post-purchase survey asks customers a few questions right after they order, on the post-purchase page or the thank you page. The most useful question is “How did you hear about us?”, which shows which channels bring buyers; with Sellify, each answer is saved with its order so you can export it with the order details.

Where a post-purchase survey can appear

  • Thank you page: a survey block on the order confirmation page, with one or several questions. Thank you page blocks work on Basic Shopify and higher.
  • Post-purchase page: one single or multiple choice question shown before a post-purchase offer. The customer can skip it.

Questions worth asking

1. How did you hear about us?

The attribution question. It catches what analytics miss, like word of mouth, podcasts or a video seen on another device. Keep the options short and add “Other”:

  • Instagram, TikTok, Facebook, YouTube
  • Google search
  • Friend or family
  • Influencer or creator
  • Podcast
  • Other

2. What almost stopped you from buying?

Shows the objections to answer on your product pages: price, shipping costs, delivery time, sizing, trust.

3. Is this order for you or a gift?

Helps you time gift campaigns and pick the right follow-up emails.

4. Why did you choose us today?

Tells you which benefits to put forward in your ads and product pages.

5. How likely are you to recommend us?

A 0–10 rating, the usual Net Promoter Score question, to follow customer satisfaction over time.

Tips for better answers

  • Ask one to three questions; the customer has just paid.
  • Prefer choice questions over free text for the main question.
  • Translate the survey into your store’s languages.
  • Read the answers next to order value to see which channels bring the best buyers.
