The Structured Data team is planning to integrate the Media Search backend into the image search in Visual Editor (see T259896). In T259308 we'll be gathering baseline statistics on the usage of the existing image search in Visual Editor. For this task, we'd like to measure usage of media search in Visual Editor once the integration described in T259896 is complete.
Things we'd like to measure:
* What percentage of image searches in VE lead to the subsequent addition of an image to the article? This will help us understand whether the search results are useful.
* The location in the image grid of the image that is chosen. This will help us understand the impact that the grid has on the success of a search, and we may choose to change the grid in response.
* How often image search in VE is used. This will help us know the importance of focusing on this feature in the future, and also whether changing the results leads to increased usage.
Note: We've also thought about measuring this by using an edit tag that indicates that an image was added via image search in VE; that would be an additional useful metric but is separate from this task (see T266067).
