About GradeSite

Your website, graded honestly.

GradeSite is a free website audit tool that checks what actually matters — and tells you exactly what to fix.

What we check

Paste any URL and GradeSite runs 60+ real checks across six categories: SEO, Performance, Mobile, Security, Accessibility, and AI Readiness. We fetch your page, parse the HTML, inspect headers, pull Core Web Vitals from Google's PageSpeed Insights API, and test whether AI assistants can actually find and cite your content.

Each check contributes to a score out of 100. No BS inflation — if your site has problems, you'll see them. The free summary shows your scores and top issues per category. The full report ($19) gives you every check result, prioritized fix instructions, and copy-paste AI prompts to fix each issue.

Most website graders stop at SEO and speed. GradeSite is the first to include AI Readiness — checking your llms.txt, AI crawler permissions, structured data, FAQ schema, and author signals. Because if ChatGPT, Claude, and Perplexity can't find you, you're invisible to a growing portion of how people search the web.

Why this exists

Most website owners know their site "looks fine" on their laptop. They don't know about the missing meta descriptions, the security headers they never set, the accessibility issues excluding real users, or the fact that every major AI assistant is blocked by their robots.txt.

The existing tools are either too technical (Lighthouse dumps a wall of metrics), too expensive (enterprise platforms), or too shallow (those "free SEO checkers" that just want your email). GradeSite gives you a clear, honest grade — like a report card — and tells you what to fix first.

No account required. No email gate. Just paste a URL and get your score.

Creator · Facet Works

GradeSite was built by Henry Wiggins at Facet Works. The idea was simple: most website owners don't know what's broken until a customer complains or their traffic drops. GradeSite gives you the answers before that happens.

Facet Works builds software products and provides technical consulting for businesses that need things built right. If you need help with your website, app, or digital infrastructure — whether it's fixing the issues GradeSite found or building something new — reach out.
