Create a mobile “first-screen” optimisation strategy for [LandingPageType] landing pages fed by [TrafficChannel] in [Region]. Audit current hero load sequence, messaging hierarchy, and CTA prominence. Propose content and layout variants (e.g., sticky benefits bar, social proof chip, price anchoring) aligned to screen height breakpoints.
Output as: (1) a variant matrix (V1–V4) with message, asset spec, and expected behavioural change; (2) a rendering order plan (critical resources, lazy loads, media formats) tied to performance budgets; (3) an experiment brief with hypotheses, target [PrimaryMetric], and guardrails (scroll depth, bounce); (4) a creative QA checklist for responsive behaviour across popular DPIs.
Mandate image aspect ratios, tap target sizes, and safe zones to avoid content truncation. Include a contingency for low-bandwidth users (e.g., lightweight alt hero).
