|
|
|
## 매 한 줄
|
|
> **"매 Core Web Vitals 의 의 INP 의 FID 의 replace (2024-03), 매 2025 의 mobile-first + AI Overviews integration"**. 매 Google ranking signal. 매 LCP, INP, CLS 의 모두 'good' 매 의 의 의 매 boost. 매 modern: 매 AI Overviews 의 ranking 의 의 의 영향.
|

|
|
- **INP**: < 200ms (FID 의 replace 2024-03).
|

|
|

|
|

|
|

|
1. SEO ranking.
|
|
2. UX.
|
|
3. Conversion.
|
|
|
|
## 💻 패턴
|
|
|
|
### web-vitals.js
|
|
```javascript
|
|
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
|
|
```html
|
|
<link rel="preload" as="image" href="/hero.webp" fetchpriority="high">
|
|
<style>/* critical CSS */</style>
|
|
<script defer src="/analytics.js"></script>
|
|
```
|
|
|
|
### Optimize INP (yield)
|
|
```javascript
|
|
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
|
|
```css
|
|
img { aspect-ratio: 16 / 9; width: 100%; height: auto; }
|
|
@font-face { font-family: 'Inter'; font-display: swap; size-adjust: 100%; }
|
|
```
|
|
|
|
### Lighthouse CI
|
|
```yaml
|
|
- uses: treosh/lighthouse-ci-action@v11
|
|
with:
|
|
urls: |
|
|
https://staging.example.com/
|
|
budgetPath: .lighthouse-budget.json
|
|
```
|
|
|
|
### CrUX (RUM)
|
|
```javascript
|
|
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)
|
|
```html
|
|
<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.
