How scores are calculated

Every report gives four 0–100 scores plus an overall letter grade. Here's exactly what each one measures.

Grade scale

A+ 90+ · A 80+ · B 70+ · C 55+ · D 40+ · F below 40

SEO

On-page fundamentals: title tag, meta description, a single H1, canonical URL, Open Graph tags, sitemap.xml, robots.txt, image alt text, internal links, and structured data.

AI Visibility (AEO)

How citable the page is to AI answer engines: Organization & FAQ schema, clear descriptive content, brand/About identity, authorship & dates, heading structure, external citations, and industry/location info.

Schema

Breadth of JSON-LD structured data: Organization, FAQPage, LocalBusiness, Article/Product, Breadcrumb, and author/date markup.

Technical

Crawlability & hygiene: robots.txt, sitemap.xml, canonical, mobile viewport, language attribute, Open Graph, and sensible title/description lengths (measured by visual width so CJK isn't penalized).

Scores are computed from publicly fetched HTML and are heuristic — a fast directional signal, not a ranking guarantee.
