BJJ Fanatics added a pop-up with personalised offers to its Shopify thank-you page, and 11.56% of shoppers who saw it took an offer, bringing in $452,288 of extra revenue in Q4. BJJ Fanatics made the change on its own store, and it was published as an Upsell.com (formerly ReConvert) case study. This was a before-and-after rollout, not a split test.

## Result

**11.56% conversion, $452K in Q4**

- 11.56% conversion rate on thank-you page offers, as reported by the vendor.
- $452,288 in extra revenue during Q4 credited to the pop-up offers.
- 8,065 extra orders in the same quarter.
- $56.08 average order value on thank-you page orders.
- No control group: these are totals from the offers, not a measured lift over a baseline.

## Control

A standard order confirmation page with no product offers after checkout.

## Variant

A thank-you page pop-up showing extra instructional videos, exclusive rashguards and limited-edition merchandise, picked from each buyer's purchase history.

## Why it likely won (our reading)

- The offer arrives right after a purchase, when the buyer has just decided to trust the store and has payment details ready.
- Instructional videos are digital and cheap to add, so a second small purchase is an easy yes for a fan of the sport.
- Picking offers from purchase history keeps them relevant, rather than showing the same product to everyone.
- Q4 is peak buying season, which likely inflated both order counts and take rates.

## Caveats

Before-and-after result published by the app vendor, with no control group, sample size or timeframe beyond Q4. Some of the extra orders may have happened anyway through normal repeat buying.

## How to run this test

- Hypothesis: If we show a pop-up with offers matched to the order on the thank-you page, then extra revenue per order will rise because buyers are most open to a related add-on right after paying.
- Primary metric: Post-purchase revenue per order
- Guardrail: Refund and chargeback rate
- Guardrail: Repeat purchase rate in the next 60 days
- Guardrail: Customer support contacts about orders
- Who should test it: Stores with a deep catalogue of related items, especially low-cost digital or accessory products. It fits less well for stores selling a single high-ticket item with nothing natural to add.
