You would have to locate the IP address of the referrer spam and get it blocked in your Google Analytics account. A referrer is useful in the statistical web analysis and determines which websites generate the most traffic. Moreover, it plays a significant role in formulating effective and powerful marketing strategies and helps you ensure your site's security on the internet.

How the spammers use it?

The HTTP referrer is always open to modifications and can be edited easily, which makes it suspicious for webmasters and beneficial for spammers. The hackers and spammers usually change the referrer property to a web page they want to promote. There are two main reasons why they choose to do such things.

To increase traffic

The spammers develop automated scripts which generate visits to hundreds to thousands of sites with fake referral URLs, usually more than ten visits per day. The webmasters and bloggers can notice an increase in the traffic and the impressions are generated in their Google Analytics accounts in a large number. These fake URLs are often used to trick with your AdSense account and to edit your log files. You can filter them out in your Google Analytics account so that the spammers' sites receive no traffic on your behalf.

To increase external links

Some of the blogs and sites may publish a large number of refers and may include the links back to their sites. This would let the spammers and hackers generate lots of backlinks for their own websites, which would ultimately improve their search engine ranking.
