Create an executive-grade action plan to improve mobile conversion by lifting Core Web Vitals for [CompanyName] in [Region] over [Timeframe]. Analyse current LCP, INP, and CLS for the top 50 mobile landing pages, then map bottlenecks to specific fixes (e.g., image optimisation, font loading strategy, critical CSS, script deferral). Prioritise actions by projected impact on [PrimaryMetric] and risk to stability, and propose a performance budget per template. Include stakeholder ownership and sequencing aligned to sprint cadence.
Output as: (1) a prioritised table with columns: Page/Template, Metric Gap, Root Cause, Fix, Effort (S/M/L), Expected Impact (% on [PrimaryMetric]), Owner, ETA; (2) a one-page brief summarising projected aggregate uplift and dependencies; (3) a validation plan detailing A/B test or phased rollout with guardrails (e.g., error rate, bounce).
Assumptions: mobile share ≥60%, modern frameworks permitted. Include a rollback plan and monitoring checkpoints.
