Verifying and Debugging Your Hreflang Implementation

The Tag Inspector is a built-in diagnostic tool that helps you verify the correctness and consistency of the hreflang tags generated on your website. It appears directly on the front end and provides a convenient way to confirm that all alternate versions of the page are correctly linked and formatted.

Enabling the Tag Inspector

To activate the Tag Inspector:

  1. Visit Hreflang → Options → General
  2. Turn on the Tag Inspector toggle
Enabling the Tag Inspector option in the plugin settings of Hreflang Manager.

Once enabled, the inspector becomes available on all front-end pages that contain at least one hreflang tag generated by the plugin.

Using the Tag Inspector

When active, the Tag Inspector appears automatically as a floating panel in the bottom-right corner of the front end.

Important notes:

  • The Tag Inspector only evaluates hreflang tags created by Hreflang Manager. Hreflang tags added manually in a theme, or generated by other plugins, are ignored and do not appear in the inspector.
  • The Tag Inspector is displayed only when a page includes hreflang tags. When no hreflang tags are present the Tag Inspector is not displayed.
  • The Tag Inspector is displayed only if the plugin is configured to output the hreflang data as link tags using the Options → HTML Tags option.

Table View

The first screen displayed by the inspector is the Table View, which provides a clean overview of all hreflang entries detected on the current page.

It contains two columns:

  • Language/Locale – The language and locale combination displayed as text
  • URL – The destination URL for that hreflang entry
The Tag Inspector in "Table View" mode is displayed in the front end of a WordPress website as a floating panel.

This view helps you quickly check whether:

  • All intended languages are present
  • Unwanted or incorrect locales appear
  • URLs point to the correct pages

Tag View

By clicking the Tag View button inside the inspector, you can switch to a more technical perspective that displays the raw HTML <link> elements generated by the plugin.

The Tag Inspector in "Tag View" mode is displayed in the front end of a WordPress website as a floating panel.

This view is especially useful for:

  • Verifying that attributes follow the expected syntax
  • Inspecting canonical relationships
  • Diagnosing issues where search engines report malformed tags
