Description

Background

Because the mobile web version of the reading list has already been released to production, let's add instrumentation so that we can collect usage data and compare it to the desktop data.

The main flows that need to be logged are captured here in these slides. The following actions should be logged:

  • User clicks/taps on the bookmark icon to save an article
  • User clicks on the bookmark icon to unsave an article
  • When a toast appears to notify user that the article has been saved or unsaved, they click the link in the toast that takes them to the saved articles page
  • User clicks on "Saved pages" link (Note that this currently can be found in two different places; for non-AMC users, this is in the left sidebar menu. See first slide in appendix. For AMC users, this is in the user menu in the top right)
  • User clicks on any of their saved articles from their saved pages

NOT in scope:

  • User clicks on watch star (in the expanded menu of an article) -- we will do this in a future task
  • User views onboarding dialogue on mobile (this tour has not been implemented yet in production)

Design requirements

Note that these images are based on updated designs for the mobile flow. The current design may not look 100% like these.

That doesn't feel right - let's follow up on this in the new year

@Etonkovidova I think these are general web instrumentation events and not for our experiment. There should be specific events for the experiment, assuming you are correctly in the experiment (vs have reading lists as a beta feature)

@Etonkovidova Which wiki are you testing mobile instrumentation and which user account?

To override enrollment and I have the user preference set for my account:

mw.xLab.overrideExperimentGroup('we-3-3-4-reading-list-test1', 'treatment');

On test.wikipedia, when I add a page to my reading list:

we-3-3-4-reading-list-test1: The enrolment for this experiment has been overridden. The following event will not be sent:
 click {
  "action_subtype": "save_article_to_reading_list",
  "action_source": "toolbar",
  "action_context": "{\"article_count\":7}"
}

remove a page:

 click {
  "action_subtype": "remove_article_from_reading_list",
  "action_source": "toolbar",
  "action_context": "{\"article_count\":6}"
}

Click on the "saved pages" link in the notification:

 click {
  "action_subtype": "view_reading_list",

}

Click on item in my reading list on https://test.wikipedia.org/wiki/Special:ReadingLists/KFilbert-WMF

With AMC mode, click "Saved pages" in the menu on the upper right:

@Etonkovidova I think these are general web instrumentation events and not for our experiment. There should be specific events for the experiment, assuming you are correctly in the experiment (vs have reading lists as a beta feature)

Thank you, @aude! For some reason, I thought that for the events would be shown for users who enabled Reading lists via Preferences-Beta beta features.

@Etonkovidova Which wiki are you testing mobile instrumentation and which user account?

To override enrollment and I have the user preference set for my account:

mw.xLab.overrideExperimentGroup('we-3-3-4-reading-list-test1', 'treatment');

Yes, I re-checked and I saw exactly the same events as you listed. No questions left!

Questions:

  • the event are not differentiated between add an article to the Saved or to remove?
  • clicking on a saved article seems to produce only init event - is it expected?
