Finds wasted tag slots: duplicates, over-length tags, and tags already contained inside another tag.
Etsy gives every listing thirteen tags of up to twenty characters. This checks the set as a set — the wasted slots are almost never the tag you were worried about.

All 13 slots filled
Thirteen tags is not many. A tag nobody searches costs you a slot and returns nothing.
The check worth reading twice is the subset one. If every word of one tag already appears inside another — name necklace inside custom name necklace — the shorter tag wins you almost nothing, because Etsy can already match the longer tag against the searches the shorter one would have caught. It is a slot spent on a phrase you were going to rank for anyway.
You get thirteen tags of twenty characters each. That is not many, and most listings throw three or four of them away without noticing.
This finds the wasted ones. It runs entirely in your browser.
The expensive mistake is a subset tag: if you already have “cat mom shirt”, then “cat shirt” adds nothing — Etsy already matches the words individually. That is a slot spent on nothing.
Single words are almost always a waste too. Multi-word phrases match the way people actually search.
Twenty characters is the hard cap. A longer tag is not truncated, it is rejected.
Once you know which slots are dead, fill them from related keywords — the tags carried by listings that already rank for your term — and score the candidates in keyword research before committing one. The thirteen Etsy tags works a full pass over an existing listing, and the title checker covers the other half of the same match.
