Our server engine issues an authentic request mimicking Googlebot user-agent headers. It measures Time to First Byte (TTFB), analyzes full HTML response headers, inspects heading structure (H1/H2/H3), audits image alt tags, verifies canonical link directives, and validates Schema.org JSON-LD structured graphs.
