Know before the rule change takes your listing down.

Marketplaces change what they will allow constantly, and they do not send a memo. The first most sellers hear of it is a suppression notice. We watch the six marketplaces for the changes that actually get listings pulled, and email you when one lands.

What you will actually get

An email when a marketplace changes a rule that can get a listing suppressed — what changed, which categories it touches, and the specific wording to check your own listings for.

Not a newsletter. Not a weekly roundup. Some months there will be nothing, and you will hear nothing. Over your first week or so you will also get three short emails about what we do, and then those stop whether you act on them or not.

Already had one taken down? That is a different job, and there is a tool for it: Listing SOS.

See it work

Three steps, and what each one actually produces - words, pictures and video.

Give it what you have

A listing, a link, a photo, a product name, or the email a marketplace just sent you.

It writes, draws and checks, per marketplace

Six different listings and the images to go with them, each to that marketplace's limits and rules, with measured keywords behind the words.

You publish; it keeps watching

Files, exact fields or one-click fill; then daily rank, price and listing-health watch.

One product, six listingsExample · zip-top canvas tote · pictures made by Optimlister

Why each version differs: every card is written fresh to the rule printed on it - Amazon now uses a 75-character Item name plus 125-character Item Highlights and benefit bullets, Etsy uses buyer-friendly titles and up to 13 tags, eBay uses item specifics, and Walmart uses structured attributes. The meter under each title shows how much of that marketplace's title limit the example uses. Every asset here is a real generator output with its exact cost - see the receipts.
