Tech/News

Later this week, a controlled experiment will begin for editors on the 100 largest Wikipedias who are editing a section in the mobile website Visual editor. 50% of editors will notice a new "Edit full page" button that will enable them to expand their editing session to the whole page. The experiment will last ~4 weeks. This feature is intended to make it easier for people on mobile web to edit any article section, regardless of which section-edit icon they tapped to begin. Please visit T409112 to see more details about the project.

Hypothesis

If we enable people on mobile web to edit any article section, regardless of which edit icon they first tap, then the newcomer mobile edit abandonment rate will decrease by 1% because they will be able to more more easily locate the content they tapped edit seeking to change.

Decision to be made

What – if any – adjustments to the mobile web {nav Edit] button UX need to be made before we can be confident all of the following are true?

  1. .
  2. .

KPIs

The main outcomes we are trying to impact through this feature. These are what we are primarily using for evaluating the hypothesis and deciding whether to deploy an intervention more widely.

HypothesisDecision(s) to be madeMetric description
If we enable people on mobile web to edit any article section, regardless of which edit icon they first tap, then the newcomer mobile edit abandonment rate will decrease by #% because they will be able to more more easily locate the content they tapped edit seeking to change.

Secondary metrics

Used to learn about additional impact of revising the mobile web editing button behavior and are not primary targets of the intervention. They reveal side effects (both positive and negative) of trying to improve the Primary Metric with the intervention.

IDHypothesisMetric description
Curiosity #1Constructive edits by newcomers will increase because more people acting in good faith will have an easier time locating the content they tapped edit seeking to changeProportion of published edits[i] by users with ≤100 cumulative edits that are constructive [i]

ii: "Constructive edits" = edits to pages in any Wikipedia main namespace that are not reverted within 48 hours of being published

Leading indicators

TICKET NEEDED

Guardrails

Used to make sure that the new checks presented are not negatively impacting an editor’s experience completing an edit or causing disruption on the wikis. The scenarios named in the chart below emerged through T325851.

Guardrail NameMetric descriptionNotes
Constructive edits decreaseBy making it easier for people tapping edit on mobile web to change larger portions of the article, we may reduce the friction to publishing destructive edits
Edit quality decreaseProportion of published edits that add new content and are reverted within 48 hours.
Edit completion rate drastically decreasesProportion of edits started (defined as TBD) that are published.
People are blocked at higher rates

A/B Test: Decision Matrix

IDScenarioIndicator(s)Plan of Action
WARNING: Reader Growth will be running an experiment on mobile web at the same time, and on some of the same wikis, that this experiment will be running. Megan and I (Peter) are discussing offline about how/if we ought to account for this in the analysis we have planned.

Event Timeline

Next step
Per this week's offline discussion, assigning this task over to @MNeisler who is going to:

  • 1. Take first pass at drafting the measurement plan for evaluating the impact of the work we are doing in T387175
  • 2. Once a first draft of the measurement plan is in a good place, learn - through a conversation with the Experiment Platform Team – which (if any) aspects of the measurement approach we're proposing is not compatible with what Test Kitchen currently offers

"1." is done (see: measurement plan) and "2" is in progress

Next steps

Tech News draft (WIP):

Later this week, some [Wikipedia? all?] editors using the mobile visualeditor who are editing a section in Visual editor will be shown a button that can expand their editing session to the whole page. This A/B test should enable editors to more easily access the rest of the article mid-edit and lower the edit-abandonment rate. [1]

Thank you, Nick. Some edits reflected in the draft below...

v2

Later this week, a controlled experiment affecting editors [100 Wikipedias] who are editing a section in the mobile Visual editor will begin. The experiment will last ~4 weeks. 50% of the editors in the experiment will not notice any difference in their experience and 50% of editors will notice a new button that will enable them to expand their editing session to the whole page. This interventions is meant to make it easier for people on mobile web to edit any article section, regardless of which edit icon they first tap. Please visit T409112 to see more details about the metrics we will be using to evaluate the impact of this intervention. [1]

Next step
@ppelberg: update task description to include contents of measurement plan

Tech News draft slightly adjusted/simplified, and added to Description. It will be ready for announcement in the 8th December edition.
We still need to get the correct link for the "100 Wikipedias", and potentially find a place onwiki to document the screenshot and a sentence explaining it. [I'll work on those aspects]

ppelberg updated the task description. (Show Details)

Wonderful. All that you described sounds great. Thank you, Nick.

Per offline discussions with @MNeisler, we've settled on targeting a 1% decrease in edit abandonment rate. I've updated the task description in 409112#11449802 to reflect this.

Note: in parallel, we're going to investigate the feasibility of further limiting the population of people we examine through this experiment to people who we assume to be arriving with an edit in mind they are intent on making. This investigation will happen in T412318.
