Limits and behavior
- Saved rule changes go live on the storefront within a few minutes; the save confirmation states “Changes saved. Live in a few minutes.”
- Rules are applied top to bottom; drag a rule to change its priority.
- Rules have no names — a rule is identified by its position (“Rule 1”, “Rule 2”).
- Contradictory rules cannot be saved: the conflict resolver must be completed first.
- A pinned product that is out of stock in every market is not shown in recommendations; the editor and the surface KPIs flag such pins.
- On surfaces that can render outside product pages, rules apply only when the surface is shown on product detail pages — the surface carries a “Product Page Only” hint.
- The live preview is not available for every surface type; personalized surfaces return results only once the engine has session data for a shopper.
- The engagement KPI tiles (clicks, impressions, CTR, attributed revenue, attributed add-to-carts) require performance reporting to be enabled for the store; the configuration tiles (rule and product counts) always show.
- Attributed revenue and add-to-carts use approximate last-touch attribution: the shopper’s last click on the product came from a recommendation within 7 days, summed across markets without currency conversion.
Surfaces
The list shows each surface with its rule count and stock status, and can be
searched across surfaces and rules. KPI tiles above the list cover the
selected period: Recommendation Clicks, Share of All Clicks,
Active Surfaces, Custom Rules, Impressions, CTR,
Attributed Revenue and Attributed Add-to-Carts.
Click a surface to open it. The surface page shows its own tiles —
Rules, Pinned Products, Hidden Products, Targeted Products
and Surface Clicks — above the rule list.
Rules
Each rule has three parts:- When showing these products — where the rule applies: specific products, a collection, or all products.
- Show these products — products always shown (pinned) in the recommendations.
- Hide these products — products never shown in the recommendations.
Add a rule
- Open a surface from the Recommendations page.
- Click Add rule.
- Under When showing these products, choose Add products, Add collection or All products and make your selection.
- Under Show these products, add the products to pin, if any.
- Under Hide these products, add the products to exclude, if any.
- Click Save rule, then click Save on the rule list.
