Practical SEO notes
- Structured data should describe content users can actually see or verify on the page.
- Valid schema does not guarantee a rich result; search engines apply additional eligibility and quality rules.

Frequently asked questions
What is JSON-LD?
JSON-LD is a JSON-based way to describe entities and relationships. Search engines commonly recommend it for structured data because it can be separated from visible HTML markup.
Can I add FAQ schema to any page?
Only use FAQPage when the page genuinely contains the corresponding questions and answers. Rich-result eligibility can also vary by search-engine policy.
Does schema improve ranking?
Structured data helps search engines understand eligible content and can support enhanced search appearances, but adding markup alone does not guarantee higher rankings.
