**User Story**
As the **WMF Growth Team**, I want to measure the impact of the Add a Link structured task rollout on English Wikipedia, so that we can understand whether it influenced the volume of constructive edits made by newer volunteers (the WE1.1 Key Result).
As an **experienced English Wikipedia editor**, I want to assess the impact of the Add a Link structured task rollout, so that I can determine whether the additional burden on patrollers is justified.
**Hypothesis: **
Given we scale “Add a Link” to 100% of newer volunteers at English Wikipedia, then newcomer constructive activation and retention will improve, which will boost constructive edits made by newer volunteers.
**Details**
- The analysis should use the methods defined in {T389404}.
- "Constructive edits by newer volunteers" are defined as:
- Edits in the main namespace on Wikipedia.
- Made by contributors with ≤100 cumulative edits (including logged-out users).
- Not reverted within 48 hours of publication.
- Note: "Add a Link" is not available to logged-out/IP editors or temporary accounts.
- The Add a Link task was scaled from a 20% rollout to 100% on September 3, 2025, at ~16:30 UTC.

{T389404}
**Acceptance Criteria:**
- Analyze constructive edits on English Wikipedia for ~1 month before and ~1 month after the September 3, 2025 rollout.
- Identify whether there is a meaningful change in the constructive edits metric that informs WE1.1.
- Provide a data visualization of the findings.
- If possible, segment results by platform (Mobile vs. Desktop).
NOTE: the hope is that this is a fairly quick Product Analysis "check", //a full report is not needed//. We previously completed a full A/B test while partially rolled out at English Wikipedia: https://analytics.wikimedia.org/published/reports/growth/add_a_link_enwiki_ab_test_report.html
