I recently wrote a Twitter thread
about some mystery traffic I had go to my personal blog. This traffic had no referrals listed so I suspect it was a link shared on some site with noreferrer set. That ruled out someone sharing the post on link aggregators like Reddit.
Also, when I do share posts on Reddit, 70% of the traffic is on mobile. 80% of this traffic was on desktop. That implied the post was shared at either a company's Slack (which sets norferrer) or several companies' Slack channels since the traffic was also global.
This all matters because I promote Dynomantle
from my personal blog. This traffic ended up only getting me 2 signups when the bulk of it occurred, but I also noticed an increase in Dynomantle signups after the traffic bump. I'm going to continue investigation to see if I can capitalize on it or grow it using similar channels.
