CORE WEB VITALS CONVERSION AUDIT

Quantify the Revenue Lost to Frontend Latency

Every 100ms of mobile latency directly lowers transaction volume and inflates customer acquisition cost (CAC). Model the revenue upside of sub-800ms Next.js architecture.

The Science of Frontend Latency in 2026

Deloitte Retail Benchmark

Deloitte Digital's "Milliseconds Make Millions" study proved that a 0.1-second improvement in mobile speed yields an average 8.4% increase in conversions and 9.2% increase in average order value.

Google Ads Quality Score Tax

Pages with poor LCP (> 2.5s) receive lower Quality Scores in Google Ads auctions, directly increasing cost-per-click (CPC) by 15% to 30% for identical search keywords.

INP: The Interaction Bottleneck

Interaction to Next Paint measures input delay during checkout and navigation. Heavy JavaScript bundles cause mobile CPUs to freeze, leading to cart abandonment.
