2. 23.05.2018 Bad bots and referral spam Bad information, click fraud on legal advertisements, and mess up reports generated by Google Analytics. The last item on this list has many implications for a website. It results from the different malicious applications of referral spam. For example, they distort traf?c data from the in?ation they create, trick users to visiting the sites that appear on Google Analytics reports, which allow them to create back links. Since they come concealed as legitimate traf?c, they bots plagiarize website content, steal user manage to hide the referrers. Referral spam has 100% bounce rates, and limited on-page times, which tends to skew data on the reports. Consequently, the end product of these reports is mostly invalid.

It becomes dif?cult to protect a website when they use the Distributed Denial of Service. When one uproots or blocks one, several others grow in place. Ghost Referrals Most websites currently have the Google Analytics code hard-coded into them. Referral bots can scrape the unique UA code from the source code and use it to track the site. From then on, it becomes possible to send information to GA, without having to visit. They take advantage of the Google Analytics Measurement Protocol, which does not discriminate any data coming to it. Stopping Ghost Referral Spam Users can ignore ghost referrals and restore the integrity of the data used in traf?c reports. A Hostname Filter is one way to about this, as it ensures that it only takes into account information from valid websites. With such a measure in place, all ghost referrals, going forward, do not re?ect in the analytic report. It is not a permanent solution, as hackers get wind of the counter measures put in place. https://rankexperience.com/articles/article1089.html 2/3
