I have suffered from spam bots which appeared in Google Analytics. They are called "Referrer Spams" which distort the Google Analytics statistics.
For example, site-auditor.online appears as a referral on Google Analytics. But the bounce rate of this spam referrer is 100%.
Especially, many referrer spams such as biteg.xyz, boltalko.xyz, brateg.xyz and even Secret.ɢoogle.com (which is different from Secret.google.com or Secret.Google.com) attacked my site. I could see one of such spams every day on my Analytics Dashboard.
I tried to take every step which could be searched in google but I could not prevent them from appearing on the Google Analytics Reports.
I could remove them from Google Analytics with a filter to exclude a region.
As shown above, please go to Admin > All Filters. And then click on "ADD FILTER" to create a new pattern.
- Filter Type: Custom
- Select Exclude
- Filter Filed: Country, Region or City
- Filter Pattern: Samara Oblast
I also added "Russia" (as a Country) and "Saint Petersburg" (as a City). Now annoying spam referrals will not appear in your Google Analytics Reports.
