Data and performance[edit]

According to the timeline below, as of late October, related pages is now live on stable, on all Wikipedias, except Japanese, Spanish, English and French. According to our plan, it should be live on Japanese and Spanish, before discussing and moving to English and French.

Below are numbers, of feature performance so far:

Plan and analysis[edit]

The Reading team would like to move forward with making related pages a stable feature on mobile web on all Wikipedias (except for the German Wikipedia, which rejected the feature, unless they decided to re-think their vote). The decisions is based on the fact that feature performance on mobile after over 3 months of running in beta (+ 20% click-through rate) is enough matrix to enable us to move the feature to stable. The click through rate is an indication that readers are inclined to check further related topics on the articles as we offer them. This is a good starting point, in which further feature development can stem from.

Timeline and tasks[edit]

  • Announce the plan and time line by Sept 1st
  • Allow 3-4 weeks of discussion
  • On Desktop: Remove Related pages from desktop beta feature on all Wikipedias --if a community needs an exception, let us know; we understand that the feature might be helpful in populating article in relatively small or new Wikipedias
  • On mobile: Start a staged roll out, where we exclude the top 6 Wikipedias in terms of article count, deploy the feature to all other wikis at once. This helps making stable bug fixes easier, given smaller traffic
  • If all goes well, start deployment according to the above plan by early October.

Community feedback summary[edit]

  • The majority of feedback was concerned with the placement of inappropriate or redundant machine generated content on articles.
  • Concerns/comments around how the algorithm behaves
Changes have been deployed to the way how the logic of the selected articles is implemented. Initially, 2/3 of the criteria for related pages were essentially popularity (links in and featured article status). Only 1/3 was similarity. We now moved it to being 100% about similarity.(Details)
  • Concerns around the display non-free images on English WP
This has been resolved via Extension:PageImages fixes and will continue to have feature enhancement
  • Concerns around the click-through rate as a sole metric for measuring feature success.
As mentioned above, the click through rate is a helpful indication to help us realize user interest in the idea of offering articles related to the topic they are reading/browsing.
  • Related pages and See also sections
Currently, editors can override the suggested articles by placing articles manually. In the future we will be looking into different patterns of how see else is significant/present in each Wikipedia, and adapt Related Pages to be as beneficial as possible to each Wikipedia
