Say you're running a Black Friday sale on one collection, or you've got a dedicated Outlet section you want to advertise separately from your full catalog. Submitting your entire store to Google or Facebook for a campaign like that doesn't make sense — you just need a feed of those specific products.

Why a separate feed matters here

A campaign feed limited to one collection means your ad budget and product data are focused on exactly what you're promoting — not diluted across your whole catalog. It also keeps your always-on "full catalog" feed untouched, so a time-limited sale doesn't interfere with your regular Shopping campaigns.

How to do it

  1. Create the collection in Shopify (if you haven't already) — Black Friday Sale, Outlet, New Arrivals, whatever fits.
  2. Generate a feed for it in Unlimited Feed. Instead of picking "all products," choose the specific collection.
  3. Get its own feed URL. This one is separate from your full-catalog feed and only contains that collection's products.
  4. Point your campaign at it. Submit it to Google Merchant Center, Meta, or ChatGPT Ads just like any other feed.

You can run as many of these as you like — a Black Friday feed, an Outlet feed, and your regular full-catalog feed, all live and updating automatically at the same time, each with its own URL.
