User agent

Requests from Presearch carry user agents like these:

presearch_com Spider/Nutch-1.20

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3/Nutch-1.20 (Crawling agent for presearch.com index)

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

presearch[._]com

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 Presearch

Vireo keeps requests from Presearch out of your pageviews and visitors and counts them on its bot report under Search engines, 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 Presearch's user agents.
