Jessica owns a boutique that sells locally designed clothing. Her desktop traffic was steady, but mobile visitors barely converted and her mobile search rankings kept declining month after month.
The Problem Setup
The site had a full-screen email signup popup that appeared immediately when someone landed on any page from mobile. It covered the entire screen with no clear way to close it for the first five seconds. Google considers this an intrusive interstitial, which violates their mobile-friendly guidelines.
Additionally, the fixed header on mobile took up 30% of the screen, and product images required horizontal scrolling. The combination meant mobile users could barely see the actual content they came to view.
Mobile organic traffic was down 52% year-over-year. Search Console showed Google was deindexing mobile versions of key product pages because of the poor user experience. Rankings for "sustainable fashion Melbourne" and similar terms dropped from page one to page four.
After Fixing It
The popup was changed to a small banner at the bottom of the screen that didn't block content. The header was reduced to 60 pixels and collapsed when scrolling down. Product images were properly sized for mobile viewports without requiring horizontal scrolling.
Google re-indexed the mobile pages within two weeks. Mobile rankings for core terms climbed back to positions 6-9. Mobile organic sessions increased from about 340 per month to 890 within eight weeks.
More significantly, mobile conversion rate went from 0.8% to 2.3% because people could actually see the products. Revenue from mobile organic traffic increased by roughly 180%.
The changes took a developer about four hours to implement. Jessica monitors her mobile usability reports weekly now and makes sure any new features don't create similar problems. She estimates the popup alone was costing her around $3,000 monthly in lost mobile search traffic.
