Audit rules

WWW and Non-WWW Both Serve the Page

The other host variant (www or non-www) answers 200 without redirecting, so the site is served on two hosts. In a QuikSEO audit, a failure of this rule has warning severity and counts against the score. Below are the exact condition, its exceptions and the sources behind it, followed by the other rules of the same group.

http.host_variant_duplicateWarning

01 — Definition

How This Rule Is Checked

The rule is a pure function of the fetched page: no extra requests, no account settings. The same input always gives the same result.

Condition and Exceptions

Condition
Probe host_variant (www ↔ non-www): status 2xx without redirect → fail (duplicate host)
Exceptions
Twin host does not resolve (absent) or answers an error status → pass; the request failed (timeout, transport error, busy host gate) → not_checked; no probe → not_checked

Sources and Project Decision

Project decision
Severity warning is a project decision [D]. A twin host that does not resolve passes; a twin that could not be fetched is not_checked.
