TaxoMap Category Sitemap

TaxoMap Category Sitemap publishes a standards-compliant XML sitemap listing your taxonomy term archive
pages (categories, tags, and any custom taxonomy you choose) at:

https://yourdomain.com/category-sitemap.xml

Each <url> entry includes:

• <loc> — the term’s permalink, generated with get_term_link(), so it automatically respects custom
  permalink structures registered for a taxonomy (including nested/custom rewrite patterns).
• <lastmod> — the publish/modification time (ISO 8601, site timezone) of the most recently modified
  published post assigned to that term.
• <changefreq> and <priority> — configurable from the admin settings screen.

Features

• Works out of the box with the built-in category taxonomy.
• Admin screen (Settings > Category Sitemap) to check/uncheck any registered public taxonomy
  (built-in or custom), plus a free-text field to add non-public custom taxonomy slugs.
• The full sitemap XML is cached with wp_cache_set()/wp_cache_get(), and the winning post ID for
  each term’s “last modified” lookup is also cached, so repeat requests avoid re-running the
  underlying WP_Query.
• One-click “Flush Sitemap Cache” button for after bulk content changes.
• taxomapcs_sitemap_urls filter for further customizing the URL list before output.

1. Upload the taxomap-category-sitemap folder to /wp-content/plugins/.
2. Activate the plugin through the “Plugins” screen in WordPress.
3. Visit Settings > Category Sitemap to choose which taxonomies to include.
4. Visit /category-sitemap.xml on your site to confirm it renders.

If the sitemap URL returns a 404, go to Settings > Permalinks and click “Save Changes” once to flush
rewrite rules.
