Sift is an application created to generate recommendations on all Target properties. These can be seen on the Target home page, product pages, category pages — even in-store kiosks for Wedding registries.

Features:

• Allows site merchants to create filters for Target’s algorithm-based recommendations (customers “also viewed”, “ultimately bought”, etc).
• Allows users to create entirely custom recommendations (e.g. “complete your purchase”) by writing logical expressions that query Target’s entire product catalog and regenerate whenever the catalog changes.
• Generates real-time previews for users as they are creating recommendations.
