How to add schema to React

Category: framework

Plugins and apps

react-helmet-async

Manual implementation

Prefer SSR/SSG (Remix, Next, RSC) for money pages; otherwise inject JSON-LD in static shell or prerender.

Troubleshooting

Google sees empty schema
CSR-only apps may miss schema—prerender marketing URLs or move to SSR.
Invalid JSON string
Use JSON.stringify; escape user-controlled fields.

Overview

React alone is usually CSR—search engines may not execute your head updates reliably. For SEO-critical URLs, use SSR, SSG, or prerender so JSON-LD is in the first HTML response.

Helmet helps on the client; pairing with Vite SSR or a meta framework is safer for schema.
