Highlighted mobile hamburger menu: +15% mobile conversion
Commentary byLiftArchiveOur analysis, not theirsVisually highlighting the mobile hamburger menu lifted mobile conversion rate by 15% and add-to-cart rate by 22% for High Mowing Organic Seeds.
The agency Rightpoint ran this four-week A/B test, published as a VWO case study.
- Mobile conversion rate: +15%.
- Add-to-cart rate: +22%, from a starting rate the team put at 41%.
- Menu clicks, the primary metric, went up; no figure was given.
The change
Variant visually highlights the mobile hamburger menu.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The standard mobile header with a plain hamburger menu icon.
Variant
The same menu, visually highlighted so it stood out in the mobile header and drew more taps.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Mobile made up about half of sessions, and the team had found friction at the top of the funnel.
- A plain icon is easy to miss; highlighting it showed visitors where to start browsing.
- Better access to categories helps a seed store, where shoppers often look for specific varieties.
Caveats: The test ran for four weeks on mobile only. The conversion and add-to-cart figures appear in the page summary but aren't restated in the body, and no sample size or confidence level was shared.

How to run this test on your store
- Hypothesis
- If we make the mobile menu icon stand out, then more visitors will open it and find products because the main route into the catalog becomes obvious.
- Primary metric
- Mobile conversion rate
- Guardrails
- Menu open rate
- Mobile add-to-cart rate
- Search usage
- Who should test it
- Stores with lots of mobile traffic and large catalogs where browsing by category matters. It will matter less if most visitors land directly on product pages or rely on search.
Questions
Do hamburger menus hurt mobile conversion?
They can hide navigation from visitors who don't notice the icon.
Making it more visible, as here, is a low-effort way to test that.
How do you highlight a mobile menu?
Common options are a contrasting color, a background shape, or a text label next to the icon.
Keep the header layout otherwise the same so you test one thing.
What should I measure in a menu test?
Track menu opens as the primary signal, then add-to-cart and conversion to confirm the extra clicks lead to sales.
