SEO & Metadata
Search engines need meaningful content, correct document metadata, semantic headings, canonical URLs where appropriate, and crawlable navigation.
Client-only rendering can still be indexed in many situations, but server-rendered or pre-rendered HTML can improve reliability and initial content visibility for public pages.
Do not treat SEO as a React-only concern. URL design, content quality, performance, accessibility, and server behavior all contribute.
Key Takeaways
- Semantic HTML helps both users and crawlers.
- Metadata should match the actual page content.
- SEO includes performance, URLs, content, and rendering strategy.
