So you’ve got a website set up and you’re tracking traffic data with Google Analytics. After a couple of months, you start noticing increased traffic in your Google Analytics, so you go and check out your referral sources and notice some sites you’ve never heard of sending you a lot of traffic. You tell yourself traffic is a good thing, right?
Well, I hate to break the bad news to you, but you might be seeing what is known as Referrer Spam. Those sites you’ve never heard of are likely spam sites sending you bogus traffic. Other names for this are Ghost Spam and Referral Spam.
