Magnus – yes: just to be clear, this is not particularly challenging from a technical standpoint (EventLogging could be used for this purpose) and I also expect the volume of events to be low compared to page impressions, as clicks on external links are in general two steps away from a page visit (scroll to the bottom, click on the link).

The main concern is privacy and data retention, we would not be in a position to pipe this data to an external site, not even labs, and before data of this type can be collected, Legal would need to review the actual specifications, given its sensitivity.

FWIW, I once had some JavaScript added to the common JS script on Commons, collecting anonymized clicks to external links on image pages, in an attempt to give some stats to the GLAM community. That would fire off basic data like time, page, and target URL to a toolserver logging script. Volume was low enough, but I had to turn it off due to privacy paranoia soon after.

Cheers,

that’s correct: we do have aggregate entry/exit reports based on panel data from comScore for all Wikimedia properties , but no exit data at the individual article/link level. Raw request logs do not include this information and for this data to be captured we would need to add ad-hoc instrumentation in MediaWiki.

To my knowledge we don't have that data (although I await being corrected). The only reader activity logs we keep are the RequestLogs, which show us how people come in and how they navigate within our ecosystem, but not how people come out.

Subject: [Wikitech-l] Exit stats?
To: Wikimedia developers <wikitech-l@lists.wikimedia.org>


Hi,

Does Wikipedia have any exit or click-through stats, like what links
are the visitors following from an article? If yes, are those public?

Thanks,
  Strainu
