User agent

Requests from Yahoo Gemini carry a user agent like this:

Mozilla/5.0 (compatible; Yahoo Ad monitoring; https://help.yahoo.com/kb/yahoo-ad-monitoring-SLN24857.html)

Device Detector identifies it with this pattern (a case-insensitive regular expression):

Yahoo Ad monitoring.*yahoo-ad-monitoring-SLN24857

Anyone can put any name in a user agent. Where the operator publishes IP ranges, checking the request's address against them is the way to confirm a visit is genuine.

How Vireo counts Yahoo Gemini

Vireo keeps requests from Yahoo Gemini out of your pageviews and visitors and counts them on its bot report under Uptime monitors, so you can see how much it left out rather than wonder why your server logs show more traffic.

Checked by running Vireo Analytics' own bot filter over Yahoo Gemini's user agents.
