This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Already Existing Tags


This plugin detects your ‘already existing tags’ into your post each time you create or edit/save one. The found tags will be automatically assigned.


  • Easy configuration.
  • Allow or block manually added tags; the choice is yours.
  • You can choose if the plugin examines the title, the content or both.
  • You can activate a filter and select which categories will be affected and which ones will be ignored by the plugin.
  • Clean uninstall option: If this option is enabled, the plugin will leave absolutely no traces when uninstalling.
  • Visit for more info.


  • Already Existing Tags – administration panel


  1. Upload the ‘already-existing-tags’ folder to the ‘/wp-content/plugins/’ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Configure the plugin through the ‘Posts -> Already Existing Tags’ administration panel.


Will the automatic tagging function start once the plugin is installed and activated?

No. By default, ‘Turn on’ is unchecked and no category is selected.

From now on I want to examine just the tittle or just the content, but after editing the post all the previous tags are still there, why?

Because the ‘Block manually added tags’ option is disabled. With this option enabled, all the previous tags are removed before adding the new ones.

My language uses non-latin characters. Can I use this plugin?

Yes. As long as you use valid UTF-8 characters, the plugin will work.

This plugin appeared to work for pre-existing posts, but failed to populate any tags for a new post. a disappointing waste of time.

Exactly what I was looking for. Had over 1000 posts without tags and this auto-generated for every post. If you are looking to bulk edit, you can use the bulk editor on the Wordpress posts page. Just make sure to limit your posts to 6-8 or you will crash the db.

There is no competitive alternative! There is no even similar type of alternative! This is one the of the best plugin you must have it on your Wordpress keychain. It saves millions of times for big blogs. It can read the post page pretty deeply and I don’t know how but it can understand like even Google AI. It finds not just the same words but similar ones too (Please correct me if I’m wrong). I suggest this to everyone who is running small or big blog.

Many thanks to the author! This is the only plugin of the kind that I have earned with Cyrillic. Simple settings, precise work and a lot of time saved!
