Zelvorm Listings
Listings that follow the rules and use the words buyers type.
Every marketplace counts differently: Amazon's 75-character titles and backend terms in bytes, Etsy's 13 tags of 20 characters, eBay's 80. Listings checks every listing against the real rules of 8 marketplaces, scores it out of 100, finds real search phrases, and rewrites it with AI that code checks before you see it.
Start freeStep 1
Bring listings in
Paste one, import a CSV from your store or marketplace, or bring in your Commerce products.
Step 2
See exactly what's wrong
A score out of 100 with every problem listed under its field: hard limits, banned words, missing keywords, thin content.
Step 3
Fix it in one click
Fit it to the rules with code, or let the AI rewrite it: a rewrite that breaks a hard limit is never shown.
The real limits
Each marketplace's fields and limits, marked hard or guidance, with the source and the date we checked.
Bytes, counted properly
Amazon's backend search terms are counted in bytes like Amazon does, so accented letters and symbols don't push you over.
Words buyers type
Real phrases from Google's search suggestions, the words that come up most, and AI groups by what buyers want.
Keywords in the right places
Whether each target keyword is in the title, near its start, in the bullets and in the backend terms.
AI rewrites, checked by code
Written for the marketplace, checked, sent back once if it breaks a rule, then trimmed: never over a hard limit.
Bulk fix list
Import hundreds of listings and work down from the lowest score.
Every version kept
The last 40 versions of each listing with their scores, and any one can come back.
Another marketplace
Switch a listing to another marketplace and it's checked against that marketplace's rules at once.
Free, with 150 AI actions a month per shop; scoring, fitting and keyword research don't use any. Listings never writes to a marketplace: you copy the result back. Marketplaces change their rules, so we show when we last checked each one.
