About SiteTester

SiteTester is a free website audit tool that analyzes any publicly accessible website across 62 checks in 6 categories: SEO, Performance, Accessibility, Design & Structure, Aesthetics, and Security.

How It Works

Enter a URL and our edge function fetches the page HTML and metadata. All 62 checks run entirely in your browser — we parse the HTML safely using DOMParser (no scripts execute). Results include an overall letter grade, category breakdowns, and specific recommendations.

Methodology

Each check scores 0-100 based on industry best practices. Category scores are the arithmetic mean of their checks. The overall score is a weighted average: SEO (20%), Performance (20%), Accessibility (20%), Design (15%), Aesthetics (10%), Security (15%).

Known Limitations

• Cannot analyze JavaScript-rendered SPAs (fetches initial HTML only)
• External stylesheets are fetched server-side (up to 10, 500KB each)
• Color contrast is heuristic-based (not pixel-level WCAG computation)
• No real browser rendering — no visual regression testing

Who We Are

SiteTester is independently operated by a small team of web developers and SEO professionals. We built this tool to help site owners, developers, and designers quickly identify issues and improve their websites. We are committed to providing a free, transparent, and privacy-respecting audit experience.
