Missing canonical URL on WordPress

No <link rel="canonical"> tag is defined on this page. Without it, duplicate URLs (with/without www, with parameters...) can create duplicate content.

Why it matters

Duplicate content dilutes the authority of your pages in search results and can prevent Google from indexing the correct version of your content.

How to fix

  1. 1

    With Yoast SEO (automatic)

    Yoast SEO automatically generates canonical tags for all your pages. Check in Yoast → Advanced → "Canonical URL" if a custom value is needed.

  2. 2

    Manually via wp_head

    php
    add_action('wp_head', function() {
  $canonical = get_permalink();
  echo '<link rel="canonical" href="' . esc_url($canonical) . '">';
});
  3. 3

    Force www or non-www

    In Settings → General, set "Site Address (URL)" consistently with or without www. Add a 301 redirect at server level for the other version.
