Configuration-specific metrics

You can see metrics for a specific serving config on the Serving Configs page. For metric graphs, click a serving config name to go to its details page, then select the Analytics tab.

The table below provides definitions for configuration-specific metrics.

Metric Description Details
Click-through rate (CTR) The number of product detail views from a serving config's recommendation panel, divided by the total number of predict queries for this serving config. For example, if the serving config points to a Frequently Bought Together model, then the CTR would be the number of product detail pages viewed from the shopping cart recommendation panel divided by the number of predict queries on the shopping cart page.
Conversion rate (CVR) The number of add-to-cart events from a serving config's recommendation panel divided by the total number of predict queries for this serving config. Similar to CTR, except that instead of product detail views, conversion rate uses add-to-cart events.
Recommender-engaged revenue The total revenue from the recommendations for this serving config. Similar to recommender-engaged revenue for summary metrics, but for this serving config only.

To track clicks from a serving config, Retail aligns the results in predict and search responses with ingested user events. If a clicked item appears in the responses for the same visitor ID within a one hour time window, the click/purchase is treated as a result of the Retail API.

This process is fully automatic; you do not need to set anything up. However, when you configure your prediction and search requests for the first time, you should confirm that:

  • Visitor IDs in the request are the same as the visitor IDs you used in event ingestions.
  • The timestamp in the response roughly match the timestamp for that event.

When Retail API metrics are compared to the ideal expected result, or ground truth, the values might be lower, but the trends align.

A more direct alternative to the method above is to use attribution tokens. This requires significant instrumentation and is only recommended as an advanced tracking use case.
