The overall score is a weighted average of all seven dimensions. Six dimensions are scored deterministically from your HTML source, response headers, robots.txt, and sitemap. Content Clarity is assessed by Claude Sonnet using a fixed rubric. Grades within each tier use +/- modifiers (e.g., B+ = 87-89, B = 83-86, B- = 80-82).
