Performance
Mobile Lighthouse laboratory score and metrics; CrUX Core Web Vitals are kept separate and shown only when available.
Analysis
Analyse your site
Run a preliminary technical check on one public page: mobile Lighthouse performance, detected technology, key security headers and basic SEO signals. It is not a substitute for a professional audit.
Scope
What it checks
Four groups of observable technical signals from one public page, presented without turning them into a proprietary score.
Technology
Visible WordPress signals, HTML document weight and asset references found in the downloaded code.
Basic security
Presence of key HTTP headers. A missing header is a signal to investigate, not proof of a vulnerability.
On-page technical SEO
HTTP status, redirects, title, description, H1, canonical, robots, language, viewport, JSON-LD and missing alt attributes.
Interpretation
How to read the result
The report describes what the tool could observe at that moment and on that URL.
- Lighthouse is a laboratory test; CrUX summarises real-world experiences when the sample is sufficient.
- A detected or missing item needs context: on its own, it does not prove quality, risk or compliance.
- One page does not automatically represent the structure, content and behaviour of the entire website.
An automated check is not a professional audit
The automated check finds repeatable signals in code and HTTP responses. A professional audit examines goals, journeys, content, accessibility, risks, priorities and representative pages, with a reasoned basis for every conclusion.
Limits
What it cannot check automatically
The report is not a certification and cannot replace specialist checks or manual testing.
- Content quality and accuracy
- Commercial effectiveness, journeys and UX
- Legal compliance
- Complete accessibility
- Vulnerabilities or penetration testing
- Complete SEO for the entire website
- Content generated exclusively through JavaScript
FAQ
Is the analysis really free?
Yes. The tool is free and requires no sign-up. A per-IP rate limit prevents abuse.
Do you store the URL I analyse?
No. We don't persist analysed URLs — consistent with our cookieless, privacy-first approach.
Why might real-world Core Web Vitals be missing?
Real-world data comes from CrUX and appears only when Google has a sufficient traffic sample for the URL or its origin. Lighthouse remains a separate laboratory test.
What should I do after the report?
Assess the signals in context. If you need causes, priorities and site-wide impact, the next step is a professional audit or a discussion about the project.
