If you ever see a major spike in the traffic to the website and your Google Analytics account shows spam or low-quality websites, your site may have been trapped by ghost referrals or referrer spam. As this form of spam leaves a significant impact on the account and traffic information you receive, it's essential to check your Google Analytics account and observe what changes should be made... Referrer spam is the traffic of your website that comes from crawlers and bots and impersonates the referral links or referral visits, while ghost spam does not visit your site and leaves an impression in your Google Analytics account.
