What is a referrer?
A referrer is anything online that directs visitors to your website. These could be search engines, links on other websites, banner adverts, emails or anything else that redirects users to your website.
Referrer is a property of the HTTP request object sent by the browser to a web server identifying either the URL, IP Address or name of the website used to direct users to a Web page.
Referrer spam is unique that is designed to show up in a analytics dashboard to be visible to the website administrator. It shows up as traffic referral, search term or a direct visit.
Spammers often change this to a site url they want to promote, and send multiple requests to your site. The intention is for the URL to show up in your your reports. Enticing the Website Administrator to go visit the site to find out more about it. This is what they are counting on, this is designed to increase site traffic to the site in question. The truly cunning ones will direct you to an online store or filter you through an affiliate link that installs a cookie and nets them a cut of revenue when you purchase something. The really malicious ones will direct you to a site that could potentially try to install malware on your system.
Why does it affect you?
