Adding a bar of links to each flavor's product page at the top of the mobile homepage raised orders by 29% for a health food brand with three flavors. GrowthRock ran this A/B test and published it on its blog. The sample was small, 139 vs 107 conversions, so the agency says the variant only likely won.

## Result

**+29% orders (small sample)**

- Orders: +29% at 98% significance over 14 days.
- Sample: only 139 vs 107 conversions, a gap of about 30 orders, so the true lift is uncertain.
- Product page visits for the two less popular flavors rose 25% and 77%; the agency reports 99.9% significance for these.
- The best-known flavor saw little change in visits.

## Control

The mobile homepage had copy and images, with the three product pages reached through the hamburger menu or by scrolling down.

## Variant

A link bar at the top of the mobile homepage linked straight to the product page for each of the three flavors.

## Why it likely won (our reading)

- Direct links cut out the menu, so shoppers reached a product page in one tap.
- The brand was known for one flavor, so the bar showed many shoppers the other two for the first time.
- With only three products, a link bar can show the whole range at once.

## Caveats

Small sample: about 30 more orders in the variant, so the size of the lift is uncertain. The test ran 14 days, and the date was not shared.

## How to run this test

- Hypothesis: If we add direct links to each product at the top of the mobile homepage, then more shoppers will reach product pages and order because they no longer need the menu or long scrolls.
- Primary metric: Orders (conversion rate)
- Guardrail: Product page views
- Guardrail: Revenue per visitor
- Guardrail: Homepage bounce rate
- Who should test it: Small-catalog brands whose mobile homepage leads with story and imagery rather than products. Low-traffic stores should run longer and expect a smaller real lift than this test's 29%.
