Website Audit — User Guide

This tool fetches a URL server-side and runs a set of SEO, performance, accessibility, and best-practices checks, with clear, prioritized fixes. You can optionally pull live Lighthouse scores from Google PageSpeed Insights.

Quick start

  1. Enter a domain or full URL and run the audit.
  2. Review the checks, grouped by category, each marked pass / warn / fail / info.
  3. Optionally enable Lighthouse and pick mobile or desktop for real-world scores.
  4. Download the report as HTML or Markdown to share.

Categories

Checks are grouped into the standard four buckets:

  • Performance — response, render-blocking signals, and (with Lighthouse) Core Web Vitals.
  • Accessibility — common a11y issues like missing alt text and document language.
  • Best Practices — HTTPS, valid markup signals, and safe defaults.
  • SEO — title, meta description, canonical, headings, robots directives, and Open Graph.

Reading the checks

Each check shows a status and a plain-English explanation:

  • Pass — the check is satisfied.
  • Warn — a non-critical issue worth fixing.
  • Fail — a problem likely affecting users or rankings.
  • Info — context, not a pass/fail.

Lighthouse scores

Lighthouse runs through Google PageSpeed Insights and can take 15–40 seconds. Scores are out of 100 for Performance, Accessibility, Best Practices, and SEO, along with key metrics. Because PSI is rate-limited and tests a live URL, scores can vary run to run and may be temporarily unavailable.

Exporting

Use the Download menu to export the full report as HTML (nicely formatted to share with a client) or Markdown (to drop into a ticket or doc).

Caveats

  • The audit reflects what the server returned to this tool; bot-specific responses, CDNs, and geolocation can change results.
  • Scores are guidance, not a guarantee — use the prioritized fixes as a starting checklist, then re-test.
