| Feature | Benefit |
|---|---|
| Zero JS by default | Pure HTML for crawlers, instant indexing |
| Static output | Sub-second TTFB, top Core Web Vitals |
Astro.site | Canonical URL construction built-in |
| Islands Architecture | Only hydrate interactive parts |
Create a reusable <SEO /> or <Head /> component accepting title, description, og, canonical props. Place in all layouts. Use Astro.site for absolute URL construction.
Always construct canonicals with Astro.site:
const canonical = new URL(Astro.url.pathname, Astro.site);
Inject JSON-LD via <script type="application/ld+json" set:html={JSON.stringify(schema)} />. Use set:html to avoid XSS — never template string interpolation.
