What is measured
Signals available in public HTML
The report uses the HTML returned to the comparison crawler. Client-rendered content that is absent from that response may not appear, which is itself useful context when evaluating machine access.
Search metadata
Title tag, meta description, canonical URL, robots directive, viewport, and Open Graph coverage.
Content structure
Visible word count, H1-H3 usage, primary heading, internal links, and external references.
Machine-readable context
JSON-LD blocks and schema types, language declaration, canonicalization, and clear section hierarchy.
Content differentiation
Prominent terms shared by both pages and themes that appear more strongly on only one page.
Accessibility basics
Image totals and images with missing or empty alt attributes in the returned HTML.
