Schema Markup: Labeling Your Page for Search Engines
Schema markup is a vocabulary of structured labels that tells search engines what your content is, from articles and products to FAQs and events.
Schema Markup is code that labels page content for search engines.
What It Is
Schema markup adds machine-readable labels to content.
It uses a shared vocabulary to describe types and properties.
Search engines use it to understand and display pages.
Why It Matters
- It can unlock rich results and visual treatments.
- Clear labels reduce misreading by engines.
- It feeds the knowledge graph and entities.
- It helps AI systems extract facts.
- It is a signal that content is structured and serious.
How to Do It
- Pick the schema type that matches the page.
- Mark up what is visible on the page.
- Use valid syntax, JSON-LD or otherwise.
- Test with the rich results tool.
- Validate and monitor for errors.
- Keep markup in sync with content.
What to Avoid
- Marking up content that is not visible.
- Using irrelevant or guessed types.
- Spamming every type on every page.

- Treating markup as a ranking cheat.
Common Mistakes
- Copying a snippet without adapting it.
