Wickes, a UK home improvement company, had recently launched a new Kitchens site on a subdomain, and they noticed that the booking page was underperforming.
Problem
After completing a heuristic evaluation and Google Analytics funnel analysis of the booking page, I identified the following UX issues:
Over 80% of users were browsing the page on mobile devices, but mobile users were submitting the form at a -15% lower rate than desktop users.
The mobile form’s hero copy trailed out of the viewport, failing to communicate its purpose.
The form had no clear heading or subheading, causing cognitive friction.
No entry fields were visible above the fold on mobile, requiring users to scroll significantly before taking action.
The CTA button was small and lacked action-oriented copy, making it easy to overlook.
A/B Test Design and Set Up
I hypothesized that a mobile-first form redesign would improve usability and increase conversion rates. The goal was for users to land on the booking page and immediately understand that they could book a free appointment with a specialist—in seconds, not hours!
After completing a pre-test analysis to ensure that there was adequate traffic for an A/B test, I designed the variant in Figma using Wickes' existing design system. The variant featured clear, persuasive hero copy, entry fields visible above the fold, a high-contrast CTA button, and improved visual hierarchy. I then built the variant in Google Optimize using HTML, CSS, and JavaScript.
The A/B test ran for two weeks, as determined by the pre-test analysis. I monitored the test every couple of days to ensure that there were no GTM tracking issues that could skew the results.
Results
The redesigned mobile form outperformed the original in every key metric:
The variant led to a statistically significant +21% increase in mobile form submissions.
Mobile users experienced a statistically significant -9.5% decrease in form abandonment.
The variant was implemented and is projected to bring in an additional £6.4M in annual revenue.
