Flavor link bar on mobile homepage: +29% orders (small sample)
Test run byGrowthRockCRO agency
Commentary byLiftArchiveOur analysis, not theirsAdding 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.
- 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.
The change
The variant adds a bar linking straight to each flavor's product page.
Simplified mockup drawn by LiftArchive from the shared screenshots.
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 of the result, not the practitioner's claim.
- 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 on your store
- 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)
- Guardrails
- Product page views
- Revenue per visitor
- 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%.
Questions
Should a small store link products directly from the mobile homepage?
In this test, direct links to three product pages lifted orders by 29%.
Fewer taps to a product page usually helps on mobile.
Can a link bar help sell less popular products?
Here, visits to the two lesser-known flavors rose 25% and 77%.
The bar made the full range visible to shoppers who only knew one flavor.
Is a 29% lift on 246 conversions reliable?
It reached 98% significance, but small samples can overstate the size of a lift.
Treat it as a likely win and retest if you can.
