Product Feed

Definition

A product feed is the structured, machine-readable representation of a catalog — one record per sellable item, with typed attributes, identifiers, availability and price.

Feeds are not new; retailers have maintained them for Shopping and marketplace channels for years. What changes under agentic commerce is their status. A feed used to be a derivative artifact for one marketing channel. It is becoming the primary interface through which a growing share of buyers encounter the product at all.

Agents compare on attributes, not adjectives

This is the whole problem in one line.

An agent asked for a laptop under a weight threshold with a specific port configuration does not look at your photography and does not respond to your tone. It reads fields. A product whose weight lives in a sentence in the description — “impressively light at just under 1.3 kg” — is, to that agent, a product with no weight. It is excluded from the comparison before quality is ever considered.

The fix is unglamorous: lift specifications out of prose into typed fields, complete the attributes that matter in your category, and structure variants so size, colour and configuration are queryable rather than encoded in a title string.

What tends to be missing

• Category-critical specifications buried in description HTML.
• Variant structure flattened into separate products, or encoded in the title.
• Stable identifiers — GTIN, MPN, or an internal SKU that actually joins to inventory and pricing.
• Availability that reflects reality, not a nightly snapshot, when the agent will act on it now.
• Dimensional and material data that comparison questions routinely turn on.

The join-key problem underneath

A feed is only as good as the systems behind it. If your storefront, ERP and warehouse disagree about what a product identifier is, the feed inherits that disagreement — and an agent will surface a confidently wrong availability or price.

This is the same data-layer work that eCommerce AI agents depend on internally, which is why merchants who fix it once get paid twice.

Why this is the low-regret move

Standards may shift. ACP and UCP are competing and neither has won. But a complete, correctly typed catalog is required by both, improves conventional Shopping and on-site search, and was worth doing before agents existed.
