**robots.txt:**

```text
# /robots.txt
User-agent: *
Allow: /

# Block admin/private areas
Disallow: /admin/
Disallow: /api/
Disallow: /private/

# Don't block resources needed for rendering
# ❌ Disallow: /static/

```

**Meta robots:**

```html
<!-- Default: indexable, followable -->
<meta name="robots" content="index, follow" />

<!-- Noindex specific pages -->
<meta name="robots" content="noindex, nofollow" />

<!-- Indexable but don't follow links -->
<meta name="robots" content="index, nofollow" />

<!-- Control snippets -->
<meta name="robots" content="max-snippet:150, max-image-preview:large" />
```

**Canonical URLs:**

```html
