What this website grader measures
This free website grader fetches your page and scores it across the five pillars that decide whether a site attracts and converts visitors. It returns an overall 0-100 score and an A-F grade, a breakdown for each pillar, and a prioritized list of fixes ranked by impact. Crucially, your score appears instantly - there's no email gate - and it includes a pillar most graders skip: AI Readiness, which scores how likely AI engines are to cite your page.
Performance
Render-blocking scripts, document weight, image lazy-loading and modern formats, and text compression - the things that make pages feel fast.
Mobile
A responsive viewport, adaptive layout, and legible text - essential under Google's mobile-first indexing.
SEO
Title tag, meta description, a single H1, and structured data - the foundations of search visibility.
Security
HTTPS, HSTS, Content-Security-Policy, and mixed content - trust signals for visitors and Google.
AI Readiness most graders skip this
FAQ/Q&A structure, machine-readable JSON-LD schema, scannable headings, and crawler access - the signals that decide whether ChatGPT, Perplexity, and Google AI Overviews cite your content.
Why grade your website?
Your website is usually the first interaction a prospect has with your business - and small technical problems quietly cost you traffic and customers every day. A slow, insecure, or hard-to-index site loses ranking, trust, and conversions before a visitor ever reads your offer. A grader turns those invisible problems into a single, clear score and a punch-list you can act on.
The pillars aren't arbitrary - they map to factors search engines and customers actually respond to. Core Web Vitals and HTTPS are confirmed Google ranking signals, mobile-friendliness underpins mobile-first indexing, and on-page SEO determines whether you're eligible to rank at all. The newest factor - AI readiness - decides whether your content gets surfaced in AI answers, an increasingly large slice of how people find information. Grading all five in one place shows you where the biggest wins are.

How to read your website grade
90-100 (A): Excellent across the board. Maintain it and monitor for regressions after each release.
80-89 (B): Strong. Close the one or two weak pillars to reach the top tier.
65-79 (C): Several areas are costing you traffic, trust, or conversions. Work the priority fixes.
Below 65 (D/F): Multiple pillars need attention. The ranked fixes will move your score fastest - start at the top.
