The Structured Data team is planning to integrate the Media Search backend into the image search in Visual Editor. Before we do so, we'd like to have some baseline statistics on the usage of the existing image search in Visual Editor, so that we can measure the success of the Media Search integration.
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.
