Astro development
Use Astro when a React site behaves more like a marketing website than an application and needs faster static HTML, cleaner metadata and less JavaScript.
Astro DevelopmentA React-to-Astro migration is strongest for landing pages, service pages, portfolios, docs, content hubs and product marketing pages. These pages usually need crawlable content, stable layout and fast loading more than they need a full client-side application.
Forms, calculators, dashboards, games, filters and product widgets can stay interactive as islands. The rest of the page can become static HTML, which reduces JavaScript cost and makes the main content easier for search engines and AI systems to parse.
Keep URL structure stable where possible, preserve canonical URLs, rewrite title tags, add structured data, verify hreflang, update the sitemap and test the rendered HTML before launch. Search Console should be watched after deployment for indexing and coverage changes.
It can improve technical SEO when the current React site hides important content behind client-side rendering, ships too much JavaScript or performs poorly on Core Web Vitals.
No. Astro can keep React components as islands for interactive parts while static content renders as HTML.
