Schema coverage.

Schema coverage is a practical proxy for “entity clarity” — whether your pages expose structured facts (JSON-LD, microdata) that search engines and AI systems can parse consistently. SEODiff surfaces schema presence/coverage inside the report.

What to add first

Start with schema that matches the page’s purpose, then expand coverage across templates.

Homepage + company pages

Add Organization (and optionally WebSite) with name, URL, logo, and social profiles.

Articles + docs

Add Article with headline, author, dates, and canonical URL. Ensure headings and titles match.

How SEODiff helps

Schema coverage is most useful when it’s monitored over time. If a deployment drops schema on a template, you want a diff (not a guess).

Regression diffs

Catch template regressions that remove JSON-LD or break key fields.
