A few kilobytes of schema in `` per page is typically negligible.\n\nHowever, badly implemented schema can complicate HTML, debugging, and caching.\n\nKey factors:\n- **Size:** Keep JSON-LD concise—no massive embedded data dumps.\n- **Placement:** Prefer static markup over runtime JavaScript injection.\n- **Duplication:** Avoid multiple overlapping schema blocks on the same page.\n- **Caching:** For static sites, templates with schema compress well and are cache-friendly.\n\nMeasure page size before and after implementation, but in most cases, per-page JSON-LD will not materially impact load times.\n\nFocus on correctness and simplicity rather than premature micro-optimizing of the schema payload.", "@type": "Answer", "description": "Per-page JSON-LD is usually just a small script block and has negligible performance impact if you keep it concise, static, and free of duplication.
