WebDiagnosis Site Audit

Description

Find what’s actually wrong with your WordPress site, and know exactly what to fix.

WebDiagnosis Site Audit is the WordPress audit that tells you what to fix, not just another score or generic list of recommendations.

Run 170+ automated checks across 14 critical areas including SEO, security, performance, accessibility, WordPress configuration, eco-design, and more.

Every finding tells you what was detected, why it matters, how urgent it is, and how to fix it.

Stop auditing. Start fixing.

Most audit tools give you a score and leave you to figure out what it means.

WebDiagnosis turns 170+ checks into a clear, prioritized action plan.

  • 170+ checks across 14 themes
  • Clear severity: Blocker, Major, Minor
  • No false alarms: unverified checks are reported as “Not verifiable”
  • Actionable findings: every issue includes its impact and recommended fix
  • Practical guidance: know what needs to change, who can do it, and how difficult it is

Built to be trusted

A score can tell you that something is wrong. A diagnosis tells you what to do next.

WebDiagnosis never guesses when the required data cannot be verified, and never turns a minor recommendation into an emergency.

The result: less time interpreting reports, more time fixing what actually matters.

One plugin. A complete website diagnosis.

Audit the dimensions that matter to modern WordPress websites:

  • SEO & technical SEO
  • Security
  • Performance & Core Web Vitals
  • Accessibility
  • WordPress configuration
  • Eco-design & sustainability
  • And more

Know what matters. Fix what matters.

Other audit tools tell you how your website scores.
WebDiagnosis tells you what’s wrong and what to fix first.

FAQ

Does this plugin slow down my site?

No. Diagnostics only run when you trigger them. The plugin adds no frontend scripts and does not affect your visitors’ page load times.

What data is collected?

The diagnostic uses technical data such as your WordPress and PHP versions, active plugins, theme information, and server configuration. No personal data or site content is transmitted.

Do I need a WebDiagnosis account?

No. The plugin works standalone with a daily diagnostic. A WebDiagnosis account unlocks multi-page analysis, unlimited diagnostics, history, and monitoring.

Why does a check sometimes say “Not verifiable”?

Because WebDiagnosis doesn’t guess. If a check cannot access the data it needs, it reports “Not verifiable” instead of raising a potentially false issue.

Is this plugin affiliated with WordPress?

No. WebDiagnosis Site Audit is an independent plugin developed by WebDiagnosis. It is not affiliated with, endorsed by, or sponsored by WordPress, the WordPress Foundation, or Automattic.
