Rokt Dynamic Product Ads Data Specifications

Dynamic Product Ads use your product catalog to generate personalized ads that feature the most relevant products for each user. To ensure accuracy, performance, and consistent event matching, the product catalog must follow Rokt's Product Data Specification.

If you already maintain a Google Merchant Center or Meta product feed, you'll find the structure familiar. Rokt intentionally aligns to industry standards for faster onboarding.

A downloadable template is available here: Rokt DPA Product Feed Template

Catalog overview

Each row in your feed represents a product or variant. The fields below allow Rokt to display accurate product information, optimize recommendations, match user events (ViewContent, AddToCart, Purchase), and dynamically personalize creatives.

Rokt requires 8 core fields and strongly recommends additional fields for ad performance and data quality.

Feed quality and governance

Rokt automatically validates your feed for:

• Presence of required fields
• Correct formatting and accepted values
• Image accessibility and quality
• Price/availability freshness
• Product ID consistency
• Variant grouping issues

Items that do not meet required criteria are not ingested into Rokt Catalog. You must make any edits in the feed file itself.

Frequently asked questions

Do sale prices and price changes update automatically?

Yes. Rokt refreshes file-based and external feed connections once every 24 hours at 12:00 AM.

What if my catalog contains variants?

Use item_group_id to group related products. Each variant must still have its own id, price, availability, and link.
