Analyze mobile performance

Traffic on mobile is dropping and the CEO wants answers by Friday. Pull the past 90 days of mobile sessions, bounce rate, average session duration, and top landing pages for iOS and Android, compare them to desktop, and flag any pages where mobile engagement is more than 30% worse. Deliver one-page summary with screenshots of the offending pages and a recommended quick fix for each.

Before I brief leadership, make the mobile performance story obvious — surface the % drop in mobile sessions up top, list the three landing pages causing most session loss, show where bounce or load time explains the drop, and highlight any recent changes to those pages or the checkout flow that could explain it.

This morning mobile sessions fell 28% but desktop held steady; I work with a small team, the product lead is defensive, and I cannot see recent A/B tests in the same property. What is the most likely cause and what immediate checks should I run in the next hour to isolate whether it is tracking, release-related, or organic traffic loss?

Across campaigns we keep losing conversions on mobile around the same three landing pages. We waste time firefighting each week. Where should I change our routine so mobile issues get caught earlier and fixed faster — what daily checks, owner assignments, and two rules for when to roll back or patch a change?
