## Core Web Vitals 2026
|
|
|
|
| Métrica | Bom | Necessita Melhoria | Mau | Mudança 2026 |
|
|
|---------|-----|-------------------|-----|--------------|
|
|
| **LCP** | < 2.5s | 2.5-4s | > 4s | Threshold < 2.0s Q2 |
|
|
| **INP** | < 200ms | 200-500ms | > 500ms | Substituiu FID em Jan 2026 |
|
|
| **CLS** | < 0.1 | 0.1-0.25 | > 0.25 | Sem mudanças |
|
|
|
|
### Optimizações LCP
|
|
|
|
```html
|
|
<!-- Preload imagem hero -->
|
|
<link rel="preload" as="image" href="/hero.jpg" fetchpriority="high">
|
|
|
|
<!-- Lazy loading imagens below-fold -->
|
|
<img src="image.jpg" loading="lazy" alt="Descrição">
|
|
|
|
<!-- Responsive images -->
|
|
<img srcset="small.jpg 480w, medium.jpg 800w, large.jpg 1200w"
|
|
sizes="(max-width: 600px) 480px, (max-width: 1000px) 800px, 1200px"
|
|
src="large.jpg" alt="Descrição">
|
|
|
|
<!-- WebP format -->
|
|
<picture>
|
|
<source srcset="image.webp" type="image/webp">
|
|
<img src="image.jpg" alt="Descrição">
|
|
</picture>
|
|
```
|
|
|
|
### Optimizações INP (novo 2026)
|
|
|
|
```javascript
|
|
// Debounce event handlers
|
|
function debounce(func, wait) {
|
|
let timeout;
|
|
return function executedFunction(...args) {
|
|
clearTimeout(timeout);
|
|
timeout = setTimeout(() => func(...args), wait);
|
|
};
|
|
}
|
|
|
|
// Code splitting
|
|
const component = () => import('./HeavyComponent.js');
|
|
|
|
// Web Workers para tarefas pesadas
|
|
const worker = new Worker('worker.js');
|
|
worker.postMessage({ task: 'heavy-computation', data });
|
|
```
|
|
|
|
### Optimizações CLS
|
|
|
|
```css
|
|
/* Definir width/height em imagens */
|
|
img {
|
|
width: 800px;
|
|
height: 600px;
|
|
aspect-ratio: 4 / 3;
|
|
}
|
|
|
|
/* Reservar espaço para ads */
|
|
.ad-container { min-height: 250px; }
|
|
|
|
/* Font loading */
|
|
@font-face {
|
|
font-family: 'Custom Font';
|
|
src: url('/font.woff2') format('woff2');
|
|
font-display: swap;
|
|
}
|
|
```
|
|

## URL Structure Best Practices
|
|
|
|
```
|
|
CORRECTO:
|
|
https://site.pt/categoria/keyword-principal/
|
|
https://site.pt/blog/como-fazer-energia-solar-2026/
|
|
|
|
ERRADO:
|
|
https://site.pt/p?id=123&cat=5&lang=pt
|
|
https://site.pt/este-url-e-muito-longo-com-muitas-palavras-desnecessarias/
|
|
```
|
|
|
|
**Regras 2026:**
|
|
- Máximo 60 caracteres
|
|
- Hífens (não underscores)
|
|
- Lowercase
|
|
- Keyword no início se possível
|
|
- Sem stop words quando possível
|
|

### Keyword Difficulty Benchmarks
|
|
|
|
| KD | Dificuldade | DR Necessário |
|
|
|----|-------------|---------------|
|
|
| 0-20 | Muito Fácil | < 20 |
|
|
| 21-40 | Fácil | 20-35 |
|
|
| 41-60 | Médio | 35-50 |
