Microdata/RDFa conflicting with JSON-LD
Running JSON-LD and inline microdata that disagree gives Google conflicting structured data. Google recommends JSON-LD, so I consolidate on it.
What it is
Multiple markup formats disagree.
Why it matters
Conflicting signals.
How to fix it
Prefer a single format (JSON-LD).
How to find it on your site
- Check whether the page uses more than one markup format.
- Compare them for conflicts.
- Consolidate on JSON-LD and remove the others.
- Re-validate the single source.
Cross-reference to ranking and citation factors
Conflicting markup formats can confuse interpretation. A single JSON-LD source keeps it clean and is Google preferred.
Impact
Low-medium. Inferred.
Evidence
Consistent structured data; JSON-LD preferred. Google Search Central, Structured data general guidelines
