Seven JSON-LD Mistakes That Silently Kill Rich Results

Google does not warn you when markup breaks eligibility. The rich result simply never appears.

The frustrating property of schema failure is silence: no penalty, no message, just eligibility quietly revoked. The same seven defects appear in almost every audit, from plugin-injected duplicates to answers padded past extraction length, and every one of them is a fifteen-minute fix once found.

Connect the graph or lose the credit

Orphaned schema blocks validate and achieve nothing. Anchor an Organization node, then reference it from every Service, Article, and Review block so machines read one coherent entity instead of scattered claims.

Markup must mirror the visible page

Schema describing content users cannot see is the fastest route to ignored rich results. Every FAQ, rating, and offer in markup must exist on the page, at extraction-friendly length.

Key takeaways

Duplicate blocks from stacked plugins or themes
Markup describing content not visible on the page
Answers over 300 words that extraction skips
Orphan nodes never linked to the Organization

Validate quarterly, not once

Themes update, plugins collide, and a graph that passed in January throws errors by June without anyone noticing. Put re-validation on the calendar like a dependency patch.
