Next.js: Metadata и SEO — компромиссы и trade-offs

Question

Accepted Answer

`generateMetadata` только когда data-driven; JSON-LD и OG images — отдельные costs.

## Разбор

- **Static title — plain `metadata` export** — build-time, zero runtime. `generateMetadata` когда value depends on data.
- **JSON-LD не Metadata API.** Structured data — `<script>` в component body. `metadata` не emit Article/Product.
- **Client Components can't export metadata.** Lift title to parent server layout/page или server wrapper.
- **Dynamic OG (`ImageResponse`) edge compute + bundle.** Scale без headless browser; JSX subset limited (flexbox, inline styles, no grid).

## Итог

Use simplest metadata path; JSON-LD and OG images are deliberate extra work.
