About
Allows you to merge terms, move terms between taxonomies, and set term parents, individually or in bulk.
What It Does
Term Management Tools adds bulk and individual editing controls to WordPress taxonomies, letting you merge duplicate terms, reassign terms from one taxonomy to another, and reset parent/child relationships across your categories, tags, and custom taxonomies. It surfaces these actions through standard WordPress admin screens, so you can reorganize large term sets without writing custom queries or relying on phpMyAdmin. In practice, it is the kind of housekeeping plugin you reach for when your category or tag structure has grown messy.
Who It's For
This plugin fits sites with taxonomies that have outgrown their original structure: publishers cleaning up duplicate tags, e-commerce stores re-categorizing products after a rebrand, agencies migrating client content, and anyone reorganizing a large knowledge base with deep hierarchies. It is especially useful during structural migrations where dozens or hundreds of terms need to be moved or merged in one pass.
Who Should Skip It
If your site has fewer than a few dozen terms and a flat category structure, the default WordPress term editor is probably enough. Beginners uncomfortable with irreversible bulk taxonomy changes should also look elsewhere, since a botched merge is far more disruptive than a botched post edit.
The Bottom Line
Term Management Tools is a focused, well-maintained plugin that does one job and does it well, with an overall quality score of 78.5/100 held back mainly by its modest popularity and thin support footprint on WordPress.org. The 4.9 out of 5 user rating across 76 reviews is the strongest signal that it delivers on its promise for the sites that need it. If taxonomy cleanup is on your roadmap, it is a safe, low-risk install; just make sure you have a database backup before any bulk merge.
