Five categories, scored separately so you know where the damage is. New to the acronyms? SEO, PSEO, AEO and GEO explained.
Title and description measured in rendered pixels, H1, canonical correctness, lang, charset, viewport, favicon, indexability, JSON-LD, Open Graph, Twitter Card, image alt coverage, hreflang, content depth
robots.txt, whether this exact page is crawlable, sitemap declaration and expansion, HTTP→HTTPS, www canonicalization, redirect chains, and real 404s
HTTPS, mixed content, HSTS, CSP, frame protection, MIME sniffing, Referrer-Policy, Cache-Control, Ahrefs Domain Rating
Whether ChatGPT, Claude and Perplexity search crawlers can reach you, assistant fetch access, your content-usage policy, and any RSL or AIPREF licence you declare
Markdown twin, llms.txt, whether your copy survives without JavaScript, answer-ready schema, question-shaped headings, linkable sections, freshness and author signals
