Schema stuffing
Marking up everything in sight, or adding markup that exaggerates, is schema stuffing and can trigger a manual action. Markup should be accurate and relevant, not maximal.
What it is
Irrelevant types added to chase features.
Why it matters
Policy risk; Google says no special schema is needed for AI.
How to fix it
Keep schema relevant to visible content/rich results only.
How to find it on your site
- Review the markup for excessive or irrelevant types.
- Flag anything that overstates or misrepresents the page.
- Pare it back to accurate, relevant structured data.
- Re-validate.
Cross-reference to ranking and citation factors
Schema stuffing risks a manual action and trust loss. Honest, relevant markup is what gets rewarded.
Impact
Low-medium; policy risk. Direct.
