I am attempting to filter out some of the nasty analytics referral traffic. It doesn't touch my site, so htaccess is out. I have to specifically go into Google to create a filter. I have a few setup already, but am looking to try something new that will hopefully make my exclusion list a bit easier to manage. I want to block any referral traffic coming from a domain that has seo, traffic, monitize, etc. in it. This would stop about 90% of the referral traffic and would keep excluding sites. What I currently use is this:
(seomonitizer|trafficseo|seotraffic|trafficmonitizer)\.(com|org|net|рф|eu|co)
It removes each site one by one, but when a new site hits, I have to add it to the list.
I'm not sure what the regex capabilities and limitations are of the Analytics filters, but possibly this may be the foundation, I'm just not sure what goes into the middle.
