In short
Only buyers see the Thank you page, so it has less traffic than any other page and is rarely one a small store can A/B test (is my store big enough to test? explains the traffic a test needs). But it's the one page every Black Friday buyer sees, at the moment they're most interested in your store, and you can use it well without testing anything.
Who this is for: owners of small or new Shopify stores who want some of their Black Friday buyers to come back in December and January.
The short answer
- Add one thing to your Thank you page before the freeze: a code for the next order, a one-question survey, or a referral link. One, not three.
- A next-order code needs an end date and a sensible minimum. Make it a reason to come back in December, not a deeper discount on top of the sale.
- A one-question survey ("How did you hear about us?") is the cheapest research you'll ever do. Black Friday gives you more answers in four days than most small stores get in a month.
- Thank you page apps work on Shopify Basic and above, not on Starter. Blocks inside the checkout steps (information, shipping, payment) need Shopify Plus.
- Don't expect to measure repeat orders with a test at small-store volume. Treat this as a sensible default, and count codes used and survey answers instead.
The 2026 timeline
| Date | What to do |
|---|---|
| By Sun 8 November | Choose what goes on the Thank you page. Create the next-order code in Shopify with start and end dates. |
| By Fri 13 November | Add the block in Shopify's checkout editor and place a test order to see it. |
| Mon 16 November | Freeze: leave the Thank you page as it is until the sale ends. |
| Fri 27 to Mon 30 November | Black Friday to Cyber Monday. Read survey answers daily; they tell you which channels are working this week. |
| 1 to 31 December | The next-order code's window. Count how many sale buyers used it. |
The full calendar is in our general Black Friday testing guide.
What you can change, by Shopify plan
Shopify's checkout and accounts editor lets every store on the Basic plan or higher change branding (logo, colors, fonts) on the checkout, Thank you and Order status pages, and add apps that customize the Thank you and Order status pages. Apps that customize the information, shipping and payment steps of checkout are available only on Shopify Plus.
| Your Shopify plan | Thank you and Order status pages | Inside checkout steps |
|---|---|---|
| Starter | No app blocks | No |
| Basic and the plans above it, except Plus | App blocks, such as a code, survey or link | No |
| Plus | App blocks | App blocks |
If you're on Starter, you can still put the next-order code in your order confirmation email, or send it in a follow-up email a few days after the sale.
Three ideas, and how to set each one up
1. A code for the next order
The idea: buyers who just got a Black Friday deal get a reason to come back after the sale, when you're not discounting everything.
- Create it in Shopify (Discounts, Create discount, Amount off order or Amount off products). Give it a start date of Black Friday and an end date in December or January.
- Set a minimum and a limit. "$10 off your next order over $50, until 31 December" protects your margin better than "15% off anything". Limit it to one use per customer.
- Check combinations. Shopify discounts only combine when you allow it, by class (product, order, shipping). Decide whether the code combines with free shipping, and make sure it can't stack with your Black Friday discount if both are live at once.
- Make it worth less than the sale. If the next-order code is deeper than your Black Friday offer, buyers will wait for it.
2. A one-question survey
The idea: you learn where your Black Friday buyers came from, in their own words, which your analytics can't always tell you (word of mouth, a podcast, a friend's post).
- Ask one question with 3 to 5 answers, for example: "How did you hear about us?" Instagram, TikTok, Google, a friend, other.
- Keep the answers mutually exclusive and in plain words.
- Read them as shares with a margin of error, not exact figures. Course lesson 6 shows how wide that margin is at small-store numbers.
3. A referral link
The idea: a happy buyer forwards your store to someone shopping for the same gift. Link to a referral program if you have one, or to a page with a share-a-code offer. Keep the wording plain: what the friend gets, what the buyer gets, and until when.
Why you can't A/B test this at small-store volume
The Thank you page is shown only to buyers, and the outcome that matters most (a second order) happens weeks later.
A store gets about 40 orders a week. Say 4% of its buyers usually order again within 30 days, and it wants to test a next-order code against no code, with repeat orders as the goal.
- To detect a 50% rise in repeat orders (4% to 6%) at 95% confidence and 80% power, it needs 1,863 buyers per version. At 40 orders a week split between two versions, that's 94 weeks of buyers.
- Even to detect a doubling (4% to 8%), it needs 553 buyers per version: 28 weeks.
Computed with sampleSizePerVariant from Benchmyrk's statistics engine. The store and its repeat rate are illustrative.
So for a small store this is a decision, not an experiment. Pick the idea that fits your business, set it up carefully, and count what happens: how many sale buyers used the code by 31 December, and what the survey answers say. Those counts aren't a test result, but they tell you whether to keep the code in January.
Mistakes to avoid
- Three blocks at once. A code, a survey, a referral link and an Instagram button compete for one glance. Choose one, two at most.
- A next-order code with no end date. It turns into a permanent discount that lives in group chats.
- A code that stacks with the sale. Test the combination with a test order before Black Friday.
- Survey answers that overlap. "Social media" and "Instagram" in the same list split the same people.
- Editing the Thank you page during the sale. Changes to checkout pages are changes to checkout. Keep them to before the freeze.
- Judging the code on December revenue alone. Some of those buyers would have come back anyway. Count it as a rough guide.
