Clickstream: mobile vs. desktop, empty referrers - Analytics

9 Jun 2020

Hi Analytics team,

Quick question:
Does the Clickstream data
<https://dumps.wikimedia.org/other/clickstream/readme.html> lump
together *mobile
and desktop?*
It seems to be hinted at here
<https://meta.wikimedia.org/wiki/Research:Wikipedia_clickstream>, but it's
not mentioned explicitly. It just says that the 2015 data is for desktop
only, which seems to imply that after that it's desktop + mobile.

Also, I was wondering if anyone has any insights into what might cause
*referrers
to be empty?* I tried googling, but the issue is clouded in mystery and
seems to depend a lot on browser and website specificities. Any insights
(small or big) would be appreciated!

Thanks a lot!
Bob
