The audit
Six categories.
60+ checks.
Each audit runs real checks — not surface-level pattern matching. We inspect headers, parse your HTML, and pull Core Web Vitals from Google's own infrastructure.
SEO
20 ptsTitle tags, meta descriptions, headings, Open Graph, sitemaps & more
We analyze your on-page signals the way search engines do — structured data, canonical URLs, internal linking, and content hierarchy.
Performance
20 ptsPage size, load speed, Core Web Vitals, caching & compression
Real Core Web Vitals via Google PageSpeed Insights, plus transfer size analysis, render-blocking detection, and caching policy checks.
Mobile
15 ptsViewport config, responsive design, touch targets & font sizing
Viewport configuration, responsive breakpoints, touch target sizing, font readability, and horizontal scroll detection.
Security
15 ptsHTTPS, security headers, mixed content & cookie policies
HSTS, Content-Security-Policy, X-Frame-Options, cookie flags, mixed content, and certificate validation.
Accessibility
15 ptsAlt text, form labels, ARIA landmarks, heading structure & language
WCAG-informed checks for image alt text, form labeling, ARIA landmarks, skip navigation, focus management, and color contrast.
AI Readiness
15 ptsIs your site visible to ChatGPT, Claude, and Perplexity? We check.
We test your llms.txt, AI crawler permissions in robots.txt, structured data for LLM comprehension, FAQ schema, content citability, and author trust signals. Most websites fail these checks.

The blind spot
Google rankings won't save you.
AI is the new search.
ChatGPT, Claude, Perplexity, and Gemini are answering millions of questions every day — often without sending users to Google at all. If your site blocks AI crawlers or lacks the structured data they need, you're invisible to a growing portion of web traffic.
GradeSite is the first audit tool that tests whether LLMs can actually discover, understand, and cite your content. We check your llms.txt, AI crawler rules, schema markup, content citability, and author trust signals — the signals that determine whether AI recommends you or your competitor.
