In order to better understand how the new MediaSearch on Commons behaves, we should have one (or multiple) dashboard(s) that allow us to monitor search metrics. The metrics we're interested in are:
* Number of searches made
* Number of search sessions
* Number of searches per session
* Search session length
* Click-through rate (to quickview and from quickview to file pages)
* Average position of clicked result in successful searches
* How often concept chips are clicked/what percentage of users click a concept chip during their search session
* What percentage of users use a filter during their search session
* What percentage of users use more than 1? 2? 3? filters in their session
* What filters are used the most
* What percentage of users/how many users use the functionality to copy the filename or wikitext
We're interested in having this for both the existing search on Commons as well as MediaSearch, and might create specific sub-tasks for each.
