Calculating Click-through Rate in Search Performance Graphs¶

Click-through rate (CTR) in Hello Retail Search performance graphs is calculated as the total number of clicks divided by the number of counted searches. This page explains what counts as a search in this context.

To determine what counts as a search, Hello Retail groups rapid query refinements into a single search. If a user extends or abbreviates a previous query within 60 seconds, the system treats it as the same search and does not increment the search count.

The time window for this grouping is 60 seconds. If a user runs another query after 60 seconds, it starts a new search and is counted.

For example, if a user performs the following queries:

lou

loung

If the second query occurs more than 60 seconds after the first, both "lou" and "loung" are counted as separate searches.

Another example is:

lou

loung

lou

If these queries occur within 60 seconds of each other, they are counted as one search because they are refinements of the same intent.

This grouping provides a more accurate view of user behavior by counting distinct searches rather than each keystroke-level refinement. It reduces noise in the data and produces a CTR that better reflects meaningful search interactions.
