Optimised mobile commerce through strategic UX research, A/B testing, and interface redesign — achieving 59% higher conversion rates.
The EE Business Shop was to undergo a migration from its legacy to CMS to a custom CMS, for strategic reasons. During this time, as a product design team we had a limited time-window to conduct and extract existing research to produce a new optimised journey that would lead to improved order conversion. This involved an intensive process of discovery, ideation and testing with strategic thinking in order to execute an improved journey in such a limited timeframe.
During product discovery, I deep-dived into the existing site's analytics. Despite receiving a significant portion of users accessed the site via mobile, conversion rates lagged significantly behind desktop.
Users reported they struggled to compare plans side-by-side, making it difficult to make informed decisions.
Product pages were excessively long, especially on mobile, causing user fatigue and abandonment.
Lack of granular filtering for data allowances made it hard for users to find the right plan.
Faciltating a UX workshop which combined design and non-design stakeholders (Product Owner, Business Analyst, Marketing). During this session we compiled the analytics, user research insights and brought everyone together to define the main problems we wanted to solve and bring into the migration/optimisation with a mobile-centric mindset. As a group we then voted on the best features and the most popular ones were considered for design.
Rapid prototyping to explore multiple solutions, focusing on mobile-first filtering and product comparison. This enabled me to be proactive by feasibility reviewing the mid-fidelity design without wasting time on finer details such as colouring and theming. This also helped establish which components were readily available in our component library and which would need to developed as custom.
Testing dropdown filters vs. chip filters to determine which interface drove better engagement and conversion. With support from the Conversion Rate Optimisation (CRO) team we were able to run 2 A/B tests with the differing functionality. We were then able to compare and contrast the funnel data and order conversion to establish which approach would be better.
































Moving from hidden dropdowns to visible chip filters transformed user engagement.
Conversion Rate Optimisation (CRO) A/B testing showed chip filtering variant was far more effective for order conversion.
Analytics showed an increase in order conversion in the migrated journey than the pre-existing one.
