Features

HyperTaxonomy adds term organization, relationships, and relevance-scored search to any WordPress taxonomy — all built in, with no external plugin required.

• Term Groups — Organize terms into hierarchical groups (built-in, no external plugin required).
• Term Inclusions — Include another term’s posts in an archive; bidirectional inclusions act as synonyms.
• Term Relationships — Semantic connections between terms, optionally mapped to core inclusion.
• Term Redirects — 301 redirects with automatic chain collapsing and circular-reference detection.
• Term Icons — Media-library icons with colored icon-shaped placeholders; SVG support.
• Search Widget — Modular form builder (pills, checklists, text fields, geo distance filter) with AJAX/POST modes; [htax_distance_field] adds postal-code and geolocation filtering when As the Crow Flies is active.
• PowerSearch — Field operators (title:, tags:, …), boolean operators, and configurable scope; proximity operator (near:, with -near: to exclude) when As the Crow Flies is active.
• Content-Based Tag Suggestions — The block editor suggests unassigned tags based on post content, ranked by prominence.
• Sticky Posts — Pin posts to specific term archives.
• Hidden Terms — Role-based term visibility, fully integrated with the search index.
• Merge Terms — Consolidate duplicate terms, transferring posts and relationships with optional 301 redirect stubs.
• Taxonomy Conversion — Move terms between taxonomies with optional 301 redirect stubs so old archive URLs keep working.
• Display Shortcodes & Blocks — Term lists, tag clouds, alphabetical indexes, and group hierarchies for any taxonomy.
• Post List Shortcodes & Blocks — Filtered post lists and related posts via shortcodes or Gutenberg blocks.
• External Posts — Fetch related posts from peer WordPress sites and RSS/Atom feeds via TermConnect ([tc_peer_posts]).
• Integration API — Automatic inclusion expansion for third-party queries, plus a REST endpoint for programmatic access.
• Import / Export — JSON-based data migration, with a Tag Groups migrator included.

Coming from Tag Groups?

Tag Groups (rebranded “PublishPress Tag Groups” in October 2026) is the plugin most commonly used for taxonomy term organization. For a side-by-side breakdown of how HyperTaxonomy compares — including what it adds beyond grouping — see HyperTaxonomy vs. PublishPress Tag Groups.

Switching away from Tag Groups and keeping it alongside HyperTaxonomy are both supported: the importer can migrate your group structure once, or sync it continuously while Tag Groups stays your group-management tool. See Import & Migration.
