What you will learn in this track

Understand the mobile drop-off, apply mobile UX principles, use Core Web Vitals, and optimize your shop with the 15-point mobile audit.

• After completing this module, you'll be able to measure your shop's mobile conversion gap using your own analytics data, translate it into euros, and explain the four main causes - context, input friction, load speed, and missing trust signals - so you can prioritize actions by revenue impact rather than gut feeling.
• By the end of this module, you'll apply eight mobile UX principles to your product pages and checkout forms: thumb reach, 44-pixel touch targets, sticky CTAs, collapsed navigation, visible filters, streamlined forms with autofill, readability at sixteen pixels and above, and progressive disclosure.
• After completing this module, you'll measure LCP, CLS, and INP on your most important mobile pages using free tools like PageSpeed Insights, prioritize technical fixes like image optimization, lazy loading, fonts, and script audits by conversion potential, and make the case for speed in euros rather than seconds.
• After completing this module, you'll run the fifteen-point mobile audit across the five blocks - Device & Interaction, Navigation & Search, Product & Checkout, Speed & Readability, and Trust & Errors - on a real smartphone, calculate a score, and prioritize any issues by estimated revenue impact using ICE.
