TL;DR
A European car diagnostics brand sells an OBD2 scanner alongside a paid app that unlocks hidden car features, advanced diagnostics and service tools.
On mobile, the navigation menu is the main route to the products. The original menu showed three text links and left shoppers to work out which product they needed.
As part of our Shopify A/B testing work for the store, we redesigned the menu to show the products and a way to check car compatibility as soon as it opens. The new menu lifted revenue per visitor by 11.8% and conversion rate by 9.7%.
The challenge: shoppers had to choose a product before they could see one
A car diagnostics scanner is a considered purchase. Shoppers want to know two things before they buy: does it work with my car, and which product do I need?
The store sells a small range: two scanners, a scanner and app bundle, and an app subscription for people who already own a scanner. Choosing between them is easier when you can see them side by side.
The original mobile menu hid that choice behind text links: Products, Supported Cars and More. A shopper had to tap into a section before seeing a single product, price or image.
The research: what the menu needed to answer
Our Shopify CRO research for this store combined analytics, a store walkthrough, and customer survey and review analysis.
The customer voice explained what shoppers needed to decide:
- Compatibility: 24 survey mentions named support for their exact car as the deciding factor.
- Compatibility doubt: 19 negative signals came from shoppers who couldn't confirm their car was supported before buying.
- Revenue concentration: the top three products drove most of the store's revenue.
Next, we looked at what the original menu showed new mobile visitors:
- Products: a text link, with no product names, images or prices.
- Supported Cars: a text link, with no prompt to check a specific car.
- More: support and company pages mixed.
- Account and social links: currency, login and social icons took up the rest of the menu.
The hypothesis: let the menu do the selling
If we show product cards and a compatibility check as soon as the mobile menu opens, mobile shoppers will reach the right product faster, increasing revenue per visitor.
We kept the same destinations. The test changed what shoppers saw first and how many taps it took to see it.
The variation: products and compatibility at the top of the menu
The menu kept its format: a dark panel that opens over the page, with a close button. The variation changed what shoppers see first:
- A “Supported cars” card at the top, with logos of compatible car brands, the question “Not sure if your car is supported?” and a Start here button.
- A Products section with a card for each main product, showing its image, name and a one-line description, with a badge on the bestseller.
- A single “Help & Resources” link in place of the More section.
- A shorter footer with only the language selector and Log in. Social media icons and the create account link were removed.
Each change answered a buying question:
- The compatibility card addressed “will it work with my car?” before the shopper reached a product page.
- The product cards made the range visible, so shoppers could compare options without leaving the menu.
The test measured the combined effect of these changes and does not isolate any single element.
The results: +11.8% revenue per visitor
We ran the test in Intelligems, comparing the original mobile menu with the variation.
Most of the gain came from conversion: 9.7% more visitors completed a purchase, and order value rose slightly. Together, these contributed to the 11.8% uplift in revenue per visitor observed during the test.
We used revenue per visitor as the primary success metric because it captures the combined effect of conversion and order value. After the test, we implemented the winning menu on the live Shopify store.
What this test taught us about mobile navigation
Shoppers on this store arrived with two questions, and the menu is the first place on mobile where both can be answered.
For this store, the menu needed to cover:
- Compatibility: confirming the scanner works with the shopper's car.
- Product choice: seeing the small range side by side.
- Support: finding help without it competing with the products.
The research also informed later tests on the compatibility checker and on how the store explains its app subscription.
