Creator merch sells in bursts: a drop announced on stream, a link at the end of a video, a restock in a newsletter. The people who watched are the most likely to buy, and the shopping channels are where you reach them again - which takes the product feed those channels run on. Ducted reads the catalog from the store address, every size and colour as its own record, and serves a feed per channel from it.
Every row is a store platform Ducted recognises from its address alone. Nothing to install, no API key, no export.
Ducted serves every channel from the same mapped catalog, each feed validated against that channel's spec before it goes out.
A new design gets searched for by name the day it lands. In a Google Shopping feed it is in Merchant Center from the next refresh, ready for Shopping ads and free listings once Google has reviewed it - each size and colour as its own item, the shape Google requires for apparel.
Google Shopping feed spec →Someone who clicked through from a video and left is the warmest audience a creator has. A Meta catalog lets catalog ads show them the products they looked at, at the price the store charges today.
Meta catalog feed spec →Merch that sells on short video belongs in TikTok catalog ads too: the same catalog, with TikTok's one sku_id per variant rule built in.
TikTok catalog feed spec →A drop is the worst moment to find out a feed was disapproved. Ducted checks every feed against its channel's spec as it is built: it names the field, counts the affected records and shows example rows from your own catalog.
Findings are graded Critical, Error, Warning or Recommendation, and every feed gets a verdict: rejected, issues, or clean.
Creator is €15/mo - one store, 12 feeds, up to 5,000 records, refreshed daily.
A merch store is one catalog and a lot of channels, which is the opposite shape from most feed tools: they charge per catalog and give you one channel. Start on Free with a single feed, and move up when the second channel is worth it.
