What to fix first

Includes issues from the extended diagnostic report.

  1. Distinct page titles

    Use a title that describes the purpose of this page rather than repeating the same title across URLs.

  2. Self-referencing canonical

    Declare exactly one <link rel="canonical"> whose absolute URL is this page's own final URL (same scheme, host, path and query; only a trailing slash or fragment may differ). Cross-URL canonicals belong on duplicate pages, not on the indexable page itself. Reference: Google Search Central, canonicalization.

  3. Main heading

    Add a descriptive H1 identifying the main topic.

Fix with your coding assistant

Copy a ready-to-use prompt with the issues and affected URLs.

HTTP response measurement

The three-run HTTP measurement could not be completed.

Same crawler, three sequential requests, DNS and TLS included. Timing is diagnostic only and never decides a position. This is server/network response, not browser loading or Core Web Vitals.

Static checks inspect crawler-visible HTML; they do not certify accessibility or code quality.
