About Super Site Report

Super Site Report is a free website health checker. Enter any address and it grades the site out of 100 for security, performance, SEO, accessibility and best practices, then explains every problem it finds in plain English, with a specific fix and a WordPress tip where one applies.

Why we built it

Most site owners hear about problems only after something breaks: an expired certificate, a slow mobile page, a sitemap that stopped updating, or a form that no one can use with a keyboard. Professional audit tools catch these issues, but they are usually paid, aimed at specialists, or focused on a single area such as page speed. We wanted one free report that a business owner can read in five minutes and hand to a developer.

What a scan does

  • Security: HTTPS and redirects, certificate validity and expiry, security headers, cookie flags, mixed content, exposed files, and email DNS records (SPF, DMARC, CAA).
  • Performance: server response time, compression, HTTP/2 and HTTP/3, caching headers, image formats, and a Lighthouse lab test in headless Chrome for Core Web Vitals.
  • SEO: titles, descriptions, headings, canonicals, robots.txt, XML sitemaps, structured data, and a polite crawl of up to 25 pages to find broken links, duplicates and thin pages.
  • Accessibility and best practices: language, labels, alt text, viewport settings, and the standards checks browsers expect.

Every check, its weight and the grading scale are documented on the methodology page.

Public reports

When a homepage scan has enough real content to be useful, we publish it as a report at /report/<domain>/, with score history, a shareable image and a PDF. Thin or unreachable results are kept out of search engines. Site owners can remove a report at any time from the link at the bottom of the report.

Who runs it

Super Site Report is a SuperSiteBros project. SuperSiteBros builds and looks after websites for small businesses, and this tool started as the checklist we run on every site we take on. The scanner is free with no sign-up. If you would rather someone fixed the issues for you, our care plans cover security, speed and updates.
