What is Product Feed?
A structured file of your product data that shopping platforms use to match products to searches and display them.
A worked example
Two sellers list the same product. One titles it "SKU-4471 Pickle 400g". The other titles it "Banarasi Mango Pickle 400g, No Preservatives, Homemade". The second appears for searches the first never reaches, and neither seller changed a bid.
Why it matters
On Shopping and Performance Max, the feed does the work keywords do in a search campaign. There are no keywords to bid on, so titles, attributes and product types determine which queries your products can appear for. A weak feed caps performance no matter how the campaign is structured.
Title construction carries most of the weight. Leading with terms customers actually search, including the attributes that matter in your category, and keeping the important words early all affect matching. Internal naming conventions belong in your inventory system, not in the feed.
Completeness matters almost as much. Product type, brand, GTIN where applicable, condition, availability, and category-specific attributes such as size and colour all improve matching and eligibility. Sparse feeds get shown less, and the advertiser usually blames the campaign.
The nuance most people miss
Supplemental feeds are the practical way to improve titles without rewriting your store, and most brands do not know they exist. They let you override or add attributes on top of the primary feed, so you can test better titles for your highest-margin products without touching the product database or asking a developer. Change one segment at a time and watch impression share on those products, since feed changes affect matching broadly and simultaneous edits become impossible to read.
Common mistakes
- Using internal SKU naming in titles instead of the language customers search with
- Leaving optional attributes blank when they affect matching and eligibility
- Editing the entire feed at once, which makes the effect impossible to attribute
- Treating the feed as a technical export rather than as the campaign's targeting layer
