# Preview and QA a Product Experiment

Pre-launch checklist for product experiments in Elevate A/B Testing, covering duplicate parity, reviews, inventory, sales channels, and tracking.

***

Work through this in **Preview**, before launching. Product experiments create real products in your store, so the checks here are about parity: making sure the only difference between control and variation is the one you meant to introduce.

### Parity check

This is the one that decides whether your result means anything.

| Check                           | What passes                                                                                    |
| ------------------------------- | ---------------------------------------------------------------------------------------------- |
| The intended change is present  | The variation product differs from the original in the way you meant                           |
| Nothing else differs            | Price, variants, options, and availability match unless the difference is what you are testing |
| Reviews are present             | The variation shows the same reviews as the original                                           |
| Images are present              | The variation has the same images, unless images are part of the test                          |
| Description formatting survived | Rich text, tables, and embedded media copied across intact                                     |

A duplicate missing its reviews will lose. So will one missing an image or a size option. Neither outcome tells you anything about your hypothesis.

### Store configuration check

| Check                   | What passes                                                                         |
| ----------------------- | ----------------------------------------------------------------------------------- |
| Duplicates are Unlisted | Test products do not appear in navigation, search, or collections                   |
| Sales channels limited  | Duplicates are on the online store only, not Facebook, Instagram, or other channels |
| SKUs consistent         | Every variation is identifiable as the same product to your other systems           |
| Inventory correct       | Stock and fulfilment behave the same across variations                              |
| Apps connected          | Any app that modifies product listings is applied to the variations too             |

### Storefront check

| Check              | What passes                                                         |
| ------------------ | ------------------------------------------------------------------- |
| Both products load | Control and every variation render correctly                        |
| Mobile and desktop | Both widths render correctly                                        |
| Add to cart        | Works from every variation and adds the correct product             |
| Variant selection  | Size, colour, and other options work on every variation             |
| Checkout           | You can complete a purchase from every variation                    |
| Apps and widgets   | Reviews, upsells, subscriptions, and chat appear on every variation |

### Scope check

| Check              | What passes                                                      |
| ------------------ | ---------------------------------------------------------------- |
| Right products     | Only the products you selected are in the experiment             |
| Every group paired | Each group has a product to test against                         |
| Across the set     | If you selected many products, check several, not just the first |

### Tracking check

| Check                      | What passes                                           |
| -------------------------- | ----------------------------------------------------- |
| Events arrive              | Viewing a product in the experiment produces an event |
| Correct variation recorded | The event records the product you actually saw        |
| Add to cart recorded       | Adding the product produces a corresponding event     |
