React SEO
React SEO is an SEO topic covered in SeoWiki.

Key takeaways
- SSR, SSG, or pre-rendering is the safer choice for pages that need to rank, because the important content is present in the initial HTML.
- Client-side rendering is better suited to logged-in areas, dashboards, or low-SEO sections, not pages that depend on organic search traffic.
- Each indexable route should have a unique title tag, meta description, and canonical URL.
For SEO-critical pages, relying on client-side rendering alone is riskier because search engines may not immediately receive complete content or signals from the initial HTML. Good React SEO helps important routes get discovered, indexed correctly, and rank with the right titles, canonicals, and content.

FAQ
Is React SEO-friendly?
React itself is SEO-friendly when used with server-side rendering (SSR), static site generation (SSG), or pre-rendering. Client-side rendering (CSR) alone can cause issues because search engines may not see the full content in the initial HTML.
How do I add meta tags in React?
Use libraries like react-helmet, react-helmet-async, or @unhead/react to set title, meta description, and other head elements per route.
What is the best React SEO library?
react-helmet-async is widely used for React 17/18; for React 19, check react-helmet-async or @unhead/react. Choose based on your React version and SSR setup.
