Configuration-specific metrics
You can see metrics for a specific serving config on the Serving Configs page. For metric graphs, click the configuration name and select the Analytics tab.
This table provides definitions for configuration-specific metrics.
| Metric | Description | Details |
| Click-through rate (CTR) |
The number of product detail views from a serving config divided by
the total number of predict or search queries for this configuration.
|
For example, if a recommendations 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.
|
| Add-to-cart events | The number of add-to-cart events from a serving config divided by the total number of predict or search queries for that configuration. | |
| Purchase events | The total purchase events from the recommendations or search results from this serving config. |
To track clicks from a serving config, Vertex AI Search for retail
aligns the recommendations in predict responses and search results in search
responses with ingested user events. If a clicked item appears in the predict
or search responses for the same visitor ID within a one hour time window, the
click and purchase is treated as a result of the recommendation or search result.
When you configure your recommendations or 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 matches the timestamp for that event.
When Vertex AI Search for retail metrics are compared to the ideal expected result, or ground truth, the values might be lower, but the trends align.
Unlike for recommendations, the process of attributing click to search requests is not fully automatic. So for metrics to work for Vertex AI Search for retail, an attribution token is required. However, attribution tokens are optional for recommendations.
