# Test offers and read the results

An A/B test runs two versions of an offer at once and splits traffic between them, so you can see which earns more. Set one up under **Upsell → A/B testing**. The **Analytics** tab shows what every offer earned. Test one change at a time, and give it at least two weeks.

## What this does

Guessing at discounts is expensive. A test answers the question with your own customers instead of an opinion.

## Create a test

1. Go to **Upsell → A/B testing**.
2. Select **Create test**.
3. Name it, and pick the **placement** to test on.
4. Choose your **success metric** — what counts as winning.
5. Set a **target** confidence, and a **start** and **end** date.
6. Set how traffic splits between the two versions.
7. Save.

## Test one thing at a time

The app says it on the page, and it matters: *test one change at a time, and run it for at least two weeks.*

Change the discount **or** the layout **or** the wording. Change two and a result tells you nothing — you will not know which one moved it.

Two weeks is the minimum because order volume swings by day. A test that runs Friday to Monday measures the weekend, not the offer.

## Read the results

Each test shows both versions side by side:

* **Views** — How many customers saw it
* **Conversions** — How many took it
* **Revenue** — What it earned

The stronger version is marked **Winner**, and the original is marked **Control**.

Above the list, four figures cover everything: **Active tests**, **Completed**, **Upsells added**, and **Revenue**.

## The Analytics tab

Separate from testing, **Upsell → Analytics** shows how offers are doing overall — revenue, conversion rate, and which offers performed best.

Use analytics to decide **what** to test. Use tests to decide **which version wins**.

## Good to know

**Do not stop a test early.** An offer that looks ahead after three days often is not. Wait for the end date.

**A losing test is still useful.** Learning that a 20% discount earns no more than 10% saves you 10% on every future sale.

**Views count impressions, not customers.** One customer who reloads the page counts twice. Compare the two versions against each other, not against your order count.

**Tests need traffic.** With a handful of orders a week, a two-week test will not tell you much. Improve the offer instead, and test once you have volume.

## Troubleshooting

* **The test shows no data** — Why: The offer's app block is missing from that page — Fix: Add it, then restart the test
* **Both versions look identical** — Why: More than one thing changed — Fix: Test one change at a time
* **Views but no conversions** — Why: The offer is not tempting, or the product does not fit — Fix: Try a different product before a bigger discount
* **The test ended with no winner** — Why: Not enough traffic to tell them apart — Fix: Run longer, or accept there is no real difference
* **Analytics and test numbers differ** — Why: They measure different things — Fix: Analytics covers all offers; a test covers only its own
* **The test will not start** — Why: The placement has no active offer — Fix: Publish an offer on that placement first

## FAQ

### How long should a test run?

At least two weeks. Shorter than that and you are measuring which days of the week fell inside the test.

### Can I test more than two versions?

A test compares two. To try three ideas, run one test, keep the winner, then test that against the third.

### What should I test first?

Whether a discount helps at all. Run your current offer against the same offer with no discount. Customers who have just bought are often willing without one.

### Does testing slow anything down?

No. Each customer sees one version, chosen when the page loads.

### What if both versions perform the same?

That is a real answer. Keep the cheaper one — usually the smaller discount — and test something else.
