Add dateModified to Your Schema for AI Freshness

Content freshness is a real signal AI systems weigh when choosing between competing sources for a query. A schema block where dateModified always equals datePublished — even on content that's been genuinely updated — quietly tells crawlers nothing has changed, ever.

The fix:

make sure dateModified in your Article schema actually reflects the real last-edit timestamp, not a copy of the original publish date. If your CMS has a genuine "updated at" field, wire the schema to that field specifically, not the publish date.
