Referral spammers have been making their way into our Google Analytics (GA) data without ever actually visiting our websites since around 2013.
Referral spam may show up to administrators as either a fake traffic referral, a search term, or a direct visit.
Referral spambots hijack the referrer that displays in your GA referral traffic, indicating a page visit from their preferred site even though a user has not viewed the page.
Referral spam can’t actually harm your site by triggering a fake visit (as long as you don’t click on the spam link).
