I had written in the past about discovering the Samara Oblast bots. For those of you who are unaware, just quickly check in your Google Analytics, in the Audience reports section the Location report.
If you are receiving a bunch of traffic from Russia, then it’s most likely spammy traffic. This traffic will never convert and will always be a small set of users, however with a decently large number of sessions.
I had blogged about getting traffic through bots leaving referral signatures, and it seemed as if the whole internet saw this happening on their sites. After I blogged this post, Moz.com came out with suggestions on putting filters on Google Analytics to clear our your analytics data.
