TECHNICAL CODE SPECIFICATION

Technical SEO Code Standards

Term Code: TECH-2026-CODE

This specification outlines code-level optimization guidelines for Google Core Web Vitals (LCP < 1.2s, INP < 200ms, CLS < 0.1), canonical tag hygiene, and IndexNow real-time pinging.

1. Core Web Vitals Performance Targets

  • LCP (Largest Contentful Paint): Target sub-1.2s via WebP image optimization and Cloudflare Worker edge caching.
  • INP (Interaction to Next Paint): Target sub-200ms by minimizing long JavaScript main thread tasks.
  • CLS (Cumulative Layout Shift): Target 0.00 by declaring explicit width and height attributes on visual assets.
