SEO Best Practices for Astro Websites

Prioritize Core Web Vitals

Astro ships minimal JavaScript by default, which helps LCP, CLS, and INP. Keep images optimized and avoid layout shifts.

Use Semantic HTML

Use headings in order, proper lists, and descriptive links. Search engines and assistive tech both benefit from clean structure.

Add Structured Data

Include JSON-LD for articles, organizations, and breadcrumbs. It improves rich results and click-through rates.

Build a Clean URL Structure

Short, descriptive slugs help both users and search engines. Keep routes consistent and avoid query-string heavy URLs.

Optimize Metadata

Make sure each page has a unique title, description, and canonical URL. Use Open Graph tags for social sharing.

Conclusion

Astro gives you a head start on performance. Combine that with strong metadata and structured content, and SEO becomes a predictable system, not a guessing game.
