Feeds
Feeds are the data sources ACO reads to understand what it can show.
A feed is any homogenous set of rows that ACO can read to make decisions. Every row in a feed follows the same column structure, which makes the data predictable and easy to use.
Feeds are not limited to products. For example, you can have a product catalog feed, discount list feed, or any other dataset you want ACO to rank from. In Shopify, the default feed is the product catalog.
Common feed examples
- Product Catalog - a feed of products.
- Discount Lists - a feed of discounts.
- Custom datasets - anything with a consistent row shape that ACO should consider.
Feeds are enriched by signals and affinities. Those additions give ACO more context about each row, which helps it make better decisions.
In short, feeds are the dataset ACO chooses from before sending the final result to the SDK in the shopper's browser.
