Astro SEO and Performance Checklist for Production Releases

Reliable publishing is not only about deployment success.
You also need consistent metadata and measurable performance thresholds.

Release checklist

• Canonical URL matches SITE_URL and BASE_PATH.
• Open Graph and Twitter tags are present on every route.
• robots.txt points to the production sitemap.
• Sitemap output reflects static routes.

Performance quality gates

Use Lighthouse in CI with a minimum threshold so regressions fail early:

• Performance
• Accessibility
• Best Practices
• SEO

Keep reports actionable

Treat PageSpeed as informational unless you control all runtime variables. Use it to prioritize fixes, while Lighthouse CI enforces baseline quality.
