Referral Spam
Referral Spam
Referral spam is the placement of domain names into the referral list in Google Analytics and other web analytics tools. There are two types of referral spam:
- Crawler-based, where a robot crawls your site and passes the spammers referrer. In this case there was a visit to your site, but not by a real person.
- Spoof-based where the spammer calls Google Analytics and passes the Site ID for your web site. The site ID can be randomly generated or obtained by crawling your site.
