# One Product Image vs Four Angles A/B Test

Page: https://alidemirbas.com.tr/en/lab/ab-test-library/tests/one-product-image-vs-four-angles-ab-test

## Hypothesis

Four angles may bring a higher purchase conversion rate than a single image because they show shape and details the first image cannot. A single image may instead win with a simpler, faster-loading page; the outcome depends on whether the extra detail outweighs the loading cost.

## When to run this test

Support contacts asking about the back, the side or the details, returns saying the item did not look like the photo, or sessions that zoom into the single image again and again mean shoppers cannot see enough of the product. Where the four-angle gallery answers those questions, add-to-cart and purchases in that arm should rise together. If the questions are about material or measurements, which photos cannot show, complete the product description first. Before launch, prepare the three extra views at the same resolution, lighting and color tone as the main image, without unnecessary text on top.

## Primary metric

**Purchase conversion rate (CR)**: Compare purchases per assigned visitor across the two image counts.

## Other metrics

- **Add-to-cart rate**: Check whether shoppers take the first purchase step.
- **Gallery interaction rate**: Use swipes and zooms to describe interaction; extra images create more opportunities to interact.
- **Return rate**: Track returns after an adequate, equal follow-up period.
- **Page load time**: Make sure the additional images do not slow the page.

## What to check before and during the test

- **Image count**: Compare one hero image with that same image plus three predefined angles.
- **Order**: Keep the shared first image and the order of additional images fixed.
- **Controls**: Keep existing gallery navigation consistent.
- **Media scope**: Do not add video, 360-degree views or new zoom behavior.
- **Category**: Review results within relevant product categories.

## What to watch when reading the result

- More gallery interaction is not success on its own, because extra images create more chances to swipe and zoom by design. Purchase conversion rate is the measure that counts; read add-to-cart rate and page load time next to it.
- Look at the result within the relevant product categories, and check returns only after an adequate, equal follow-up period. Make sure ahead of launch that mobile touch targets stay easy to use in both arms; if they got cramped, put the difference down to a usability problem rather than image count.
- If the extra images slow the page, some visitors may leave before tracking fires and the arms can fill unevenly. Before reading the result, check that assigned visitor counts match the planned split (sample ratio mismatch). If the split is sound, compare the two conversion rates with the [A/B test significance calculator](https://alidemirbas.com.tr/en/calculators/ab-test), and if the gap is still not significant, consider a longer run.

## Frequently Asked Questions

### Does the main image change in the multi-view variant?

No. Keep the shared main image and add the three predefined views. Preserve their order. Do not add video, 360-degree imagery or new zoom behavior.

### Does more gallery interaction mean the extra angles worked?

Use purchase conversion as the primary outcome. More images create more interaction opportunities by design. Inspect add-to-cart and matured returns as supporting outcomes.

### How should the extra images be prepared?

Keep quality, lighting and color representation comparable. Avoid unnecessary text overlays and monitor the additional loading cost.

### How should the mobile gallery behave?

Preserve consistent gallery navigation and usable touch targets. Inspect relevant product categories rather than changing navigation behavior with image count.
