매 핵심

매 Core Web Vitals (current)

LCP: < 2.5s.

💻 패턴

web-vitals.js

import { onLCP, onINP, onCLS } from 'web-vitals';
onLCP(({ value }) => analytics.track('LCP', { value }));
onINP(({ value }) => analytics.track('INP', { value }));
onCLS(({ value }) => analytics.track('CLS', { value }));

Optimize LCP

<link rel="preload" as="image" href="/hero.webp" fetchpriority="high">
<style>/* critical CSS */</style>
<script defer src="/analytics.js"></script>

Optimize INP (yield)

button.addEventListener('click', async () => {
  await scheduler.yield();
  for (let i = 0; i < 1000000; i++) {
    if (i % 1000 === 0) await scheduler.yield();
    heavyWork(i);
  }
  updateUI();
});

Optimize CLS

img { aspect-ratio: 16 / 9; width: 100%; height: auto; }
@font-face { font-family: 'Inter'; font-display: swap; size-adjust: 100%; }

Lighthouse CI

- uses: treosh/lighthouse-ci-action@v11
  with:
    urls: |
      https://staging.example.com/
    budgetPath: .lighthouse-budget.json

CrUX (RUM)

fetch(`https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=${url}&key=${KEY}`)
  .then(r => r.json()).then(data => {
    const lcp = data.loadingExperience.metrics.LARGEST_CONTENTFUL_PAINT_MS;
  });

Schema.org (AI Overview readiness)

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "author": {"@type": "Person", "name": "...", "url": "/author/jane"},
  "datePublished": "2025-...",
  "dateModified": "2026-..."
}
</script>

매 결정 기준

상황	Lever
Slow LCP	Preload, inline CSS, image optim
High INP	Yield, worker, code-split
High CLS	Reserve space, font-display
AI Overview	Schema + clear summary

기본값: 매 web-vitals + Lighthouse CI + LCP < 2.5s, INP < 200ms, CLS < 0.1 + schema.org + AI Overview-ready.
