[SPIKE] Document past interventions' impact on constructive activation
Closed, ResolvedPublic

Description

In the 2024-2025 fiscal year, the Editing, Growth, iOS, and Research Teams will work together to increase constructive activation. [i]

In T371726, we are working to set the percentage by which we'll strive to improve the baseline constructive activation rate (T360829).

In this ticket, the Editing, Growth, iOS and if applicable, Research Teams will look back at the impact past interventions [ii] they've deployed have had on improving constructive activation to inform the improvement target we'll ultimately set in T371726.

Past interventions

The list below includes the interventions that have sought to impact constructive activation (or related/analogous metrics) and effect they were proven to cause. Please see the Google Sheet version for more detailed documentation.

Intervention nameDescriptionAnalysis datePlatform(s)Target AudienceObserved impact[1]Notes/link(s)
Newcomer tasksIn November 2019, the Growth team added the "newcomer tasks" feature to the newcomer homepage, which provides a feed of suggested articles to edit tailored to the area of interest of the newcomer.November 2019 through May 2020Mobile web and desktopReviewed 97,755 new accounts logged on four pilot wikis: Arabic, Vietnamese, Czech, and Korean Wikipedias.26.7% increase (16.1% → 20.4%; 4.3pp)Newcomer Tasks/Experiment Analysis
"Add a link" structured taskIn May 2021, the Growth team added the "Add a Link" structured task to the "newcomer tasks" feature on the newcomer homepage.May 2021 through October 2021Mobile web and desktopReviewed 130,179 new accounts data logged on 10 pilot wikis: Arabic, Bengali, Czech, Vietnamese, Russian, French, Polish, Romanian, Persian, and Hungarian16.9% increase (20.7% → 24.2%; 3.5 pp).

"Add an image" structured taskIn late November 2021, the Growth team added the "Add an Image" structured task to the "Suggested Edits" module on the Newcomer HomepageJuly 2022 through October 2022Mobile web and desktopReviewed 148,412 new accounts looged on seven pilot wikis: Arabic, Bangla, Czech, French, Persian, Portuguese, and Turkish.Desktop: 1.9% increase (21.6% → 22.0%; 0.4pp); Mobile: 17.0% increase (16.6% → 19.4%; 2.8pp)Add an image/Experiment analysis
Impact ModuleChanges were made to the Impact module to provide new editors more context about their impact, as well as encourage them to continue contributingFebruary 2023Mobile web and desktopFour pilot wikis: Arabic Wikipedia, Bengali Wikipedia, Czech Wikipedia, and Spanish Wikipedia22.5% activation rate for both the new impact and old impact following improvements and fixes deployed. This was the expected result as the old empty state design is very similar to the new empty state design, so we would expect to see no change in the Activation rate.

Newcomer experience marketing experimentAs part of the Wikimedia Foundation's FY21–22 pilot project, Communications and Growth teams tried various tactics to acquire and retain new Wikimedia editors on the Spanish Wikipedia. This included a new on-wiki sign-up landing page and welcome emails.May 2022 through July 2022Desktop and mobile webMarket: Spanish-speaking South, Central, and North America. Target audience: 18–45, at least college educatedNew sign-up page : 1 contructive activation (control) -> 10 constructive activations (test) (Numbers too low to establish statistical significance); Welcome emails: No effect; 0.5% increase (19.8% → 19.9%; 0.1 pp)Newcomer Experience Marketing Report
Thank you pages and thank you bannersProject undertaken as an experiment, as a collaboration by the Growth and Fundraising teams at the Wikimedia Foundation. During this project, we leveraged existing fundraising activities to ask readers and donors to create accounts.May 2022 through July 2022Thank you page (desktop); Thank you banner (mobile web)Targeted donors in Latin America, India, and South Africa; Invitation to edit sent via emails and banners on enwiki, eswiki, and ptwikiThank you page: Only 4.6% of accounts created started editing within 24 hours of creating their account. Per region activation rates range from 2.1% in Latin America (enwiki) to 8.2% in Brazil (ptwiki); Thank you banner: 16.8% of accounts were constructively activated. Per region activation rates range from 7.3% Latin America (enwiki) to 25.3% in Brazil (ptwiki) ; Organic activation rate was estimated to be between 26-36% on these wikis.Newcomer Experience Pilot Project/Thank you emails and banners
Newcomer Homepage with Newcomers Taks moduleExperiment evaluated the impact of providing a central place where newcomers can learn how peer production works and find opportunities to contribute, as a solution for attracting and retaining newcomersFebruary 2021 - May 2021Desktop and mobile web244,060 accounts registered on 27 non-English Wikipedia wikisOverall: 1% increase in the odds of activation but depends on newcomer context. Some insights: Users that were editing at time of registration saw a significant decrease in constructive article activation if they were also in the treatment group. For ssers who said they registered to read wikipedia, there was a significant increase in activation for respondents who said they created their account to read Wikipedia.Increasing Participation in Peer Production Communities with the Newcomer Homepage
2019 Growth Help PanelThe help panel was first deployed to newcomers in January 2019. The goal of the Help Panel is to provide users with easier ways to get help without them having to leave the editing context. Activation rate (not constructive activation) was identified as a target metric for the project.January 2019 - February 2019Desktop and mobile web3,848 accounts in Czech Wikipedia, 3,690 accounts in Korean Wikipedia, and 5,283 accounts in Vietnamese Wikipedia.As part of the analysis, the team used historical data to calculate an estimate of what the average activation rate for each wiki has been and the effect size we would be able to detect based on the number of users in our dataset.

ii. Where "past interventions" is relatively open-ended and includes all interventions that sought to cause a change in a metric that is similar enough to how we've defined "constructive activation" in the context of the WE 1.2 KR: "Newcomers making their first edit to an article in the main namespace of a Wikipedia projects on a mobile device (mobile web, Android, or iOS app) within 24 hours of registration, and that edit not being reverted within 48 hours of being published.

Event Timeline

MNeisler triaged this task as Medium priority.

I've completed a review of all identified past interventions that have sought to impact constructive activation. Some insights and limitations of these past interventions are noted below:

Some insights:

  • Past interventions that were able to positively impact constructive activation increased rates by 6% to 26.7% depending on intervention and platform:
    • Most of the reviewed interventions included users that registered on either desktop or mobile web but the 2022 Add an image analysis provided the following mobile web-specific results:
      • 17% increase for newcomers who registered on mobile and got the Add an Image structured task
      • 13.5% increase for the newcomers who registered on mobile and got the Add a Link structured task
  • No impacts on constructive activation were observed for the following interventions: 2022 add an image experiment on desktop (this structured task was more impactful on mobile), the 2022 Newcomer marketing pilot experiments, which included a thank you page and banner, new sign-up page, and welcome emails sent to encourage donors readers to create accounts, or the 2019 Help Panel Experiment. Some of these were because the numbers were too low to establish statistical significance.
  • There was typically a more significant impact on constructive activation rates (excludes reverted edits) compared to activation rates (includes all edits) in the growth interventions.
  • Degree of impact appears to be influenced by the following:
    • The type of task. There was a 16.9% increase for users that received access to the Add a link structured task and 5.4% increase for users that received the unstructured "add links" task.
    • Newcomer context (i.e. is the user editing at the time of registration). Users that were editing at time of registration saw a significant decrease in constructive article activation if they were in the treatment group (provided newcomer tasks on newcomer homepage).
    • Platform. On the desktop platform, there was no change in activation between users in the Add an Image and control groups, but there was an increase in activation for those who received the Add a Link structured task. On mobile web, there were increases in activation for both the Add a link and Add an image tasks.
  • There have been no significant fluctuations in baseline constructive activation rates over the last few years for users that register on either mobile web or desktop. Mobile web rates have been stable with slight YoY increases. Constructive activation rates for users that register on mobile web were about 16% in 2021, 16.6% in 2022 and 17.6% in 2024 (recent baseline calculation). I further reviewed how mobile web rates have changed over time T370726, with the removal of edits completed on Talk Pages and extended the review to all wikis.

Limitations:
The majority of interventions identified so far have been completed by the Growth team. The definition used by the Growth team in these interventions aligns with the current proposed definition[i] with the following exceptions:

  • Activation included edits completed both on Main and Talk namespaces (0 and 1). We are limiting to just edits completed on the main namespace;
  • Mobile apps has not completed any direct analysis on increases in new account activations but has measured edit volume increases, which are documented in the "mobile_app_past_inteventions" tab of the doc. While not constructive activation was not measured in these interventions, the results do help confirm the overall success of structured tasks on mobile. Note: These results were not limited to newcomers.
  • Most of the published rates include users that created accounts on either desktop or mobile web. We are reviewing registrations and edits on a mobile device (including mobile web and apps).
  • The activation rates are limited to a specific subset of pilot wikis.

i. Where "constructive activation" refers to the percentage of brand new editors who publish ≥1 edit in the main namespace on a mobile device that is not reverted within 48 hours, as measured by controlled experiments.

I've updated the task to include data from interventions @HNordeenWMF shared offline.

@SNowick_WMF, if the links are handy, might you be able up to share links to the analyses y'all completed for the following interventions so that I can document them in the task description and close out this task?

  • Image recommendations (iOS + Android)
  • Introduction of the native editor (iOS)
