Based on the finalized design from T146663 and T139310, this A/B test will have a test group that will be shown thumbnails (free use images only) for the search query results and updated metadata for each search result (that have images to display). A control group will see the currently existing search results page.
This test is expected to last a week - the Wikipedia where this test will be run on is yet to be determined, but will be based on community input.
Take into account this community feedback on using Wiktionary results.
Note: we'll need to see if the images increase the clickthroughs on search results for the listing and how long the page took to load.
Note: The images used in this test will be displayed using the PageImages API extension, similar to what is being used on the Wikipedia portal page in the search box type ahead feature.
Test group users will see for all search results returned:
- thumbnail (as available) image for the search results
Test group users will see for all search results returned:
- normal search results page
Bucket testing logic generally is as follows:
- 1 in 200 users are included in EventLogging
- Of those 1 in 200 users, 1 in 10 are included in the test
- Of those 1 in 10 users
- 50% go in a test group, labeled "serp_add_thumbnails"
- the other 50% of users will go in a control group, labeled "serp_no_thumbnails"
- The remaining chunk of the original bucketed 200 users will get a NULL (the string null, or the MySQL null, we can detect either).
Eventlogging needs to capture:
- if the user clicked on any of the top 3 search results vs the rest
- what position the result was in that the user clicked on (1st, 2nd or 3rd search result)
- how long it took the images to load on the page
- how many images were displayed as compared to the amount of the search results returned
