Date markup
AuthorityImpact: Standard
What we measure
datePublished + dateModified in JSON-LD or <time datetime>.
Why it matters for AI citation
Engines penalize undated content as potentially stale. Dated content gets freshness scoring.
How to fix
Add JSON-LD datePublished + dateModified, or a visible <time datetime> tag.
