The GrowthExperiments extension is used by Wikimedia Foundation sites for experiments done by the Growth team. The extension contains features for:
- a survey during registration
- some improvements to registration confirmation emails
- a homepage for inexperienced users with various helpful features, which also serves as an entry point for most other functionality
- showing a custom signup page to users who arrive through an outreach campaign
- suggesting easy tasks with guidance to new users, including some structured editing experiences based on suggested links and suggested images
- a help panel for suggested tasks and for generic editing, providing information and allowing communication with an assigned mentor
- features for mentors to better support newcomers
- showing information to new users about the impact they are making on the wiki
Integrations
GrowthExperiments integrates with the following extensions:
- Echo - for informing new users and mentors about various opportunities
- VisualEditor - for a better editing experience when doing suggested tasks
- PageViewInfo - for various interface elements trying to explain the user's current or potential impact, most notably the "impact" module on Special:Homepage
- MobileFrontend - for showing a mobile-optimized version of various features
- UniversalLanguageSelector - for language selection in the post-registration survey
- Flow - for messaging features ("ask help" dialog on the homepage and in the help panel) when the target page is a Flow page
- CirrusSearch - for various search features used during suggested tasks
In theory all of these extensions are optional, although the behavior of GrowthExperiments without them is not heavily tested.
The extension also uses some web APIs which are probably unavailable for non-Wikimedia wikis:
- Page Content Service for displaying task card information such as a description and an image
- Analytics Query Service for interface elements related to impact (this is abstracted away via the PageViewInfo extension on the server-side, but for client-side features that's not always possible)
- Add Link for link recommendation tasks
- Add Image for image recommendation tasks
