Practical use
Before making a decision.
What does this check actually measure?
It inspects one public initial HTML document. Server response timing is measured from Differline infrastructure and includes connection setup and TLS. JavaScript, images and fonts are not executed or loaded as in a browser, so this is not page-load or Core Web Vitals assessment.
Does a green signal mean the site is good?
No. A title or alt attribute does not prove content quality; a detected label does not prove full form accessibility. Use findings to identify basic gaps. Also test navigation, mobile enquiries and keyboard operation in practice.
Why can a check fail?
Private addresses, non-standard ports and non-HTML responses are rejected. Server blocking, oversized HTML, TLS and timeout limits can also prevent inspection. For browser performance, owners can run a full Google PageSpeed check.
