Statistical significance
Challenge
On mobile, the primary “Enquire Now” call-to-action was hidden inside the collapsed navigation menu, adding friction and leaving mobile inquiry rates well below desktop.
Solution
- Analysed the mobile user journey to find drop-off points
- Designed a sticky CTA in the mobile navigation header
- Ran the A/B test through Google Tag Manager
- Monitored behaviour and engagement in Google Analytics 4
How it worked
A GTM setup injected the sticky CTA for the test group only, with custom event tracking, cross-browser compatibility and performance safeguards so page load times were unaffected.
Results
- 185% increase in mobile inquiry submissions
- Significantly improved mobile engagement
- Narrowed the gap between mobile and desktop conversion
- Scaled the solution across all mobile pages
