Referral spam is nothing new. In fact, this type of annoying spam has been used by spammers from quite some time now; however, it has gone through a bit of evolution over the years. The classic referral spam, where spammers use bots and crawlers to create fake visits to your website, was widely distributed a few years ago. Fortunately, Google managed to restrict this type of spam effectively and now it is a less encountered problem. However, its new evolved form – Ghost spam – is the burden of many website owners nowadays. Addons.Mozilla.Org is one such form spam, which uses advanced methods to target websites and mess up their traffic and unfortunately, Google is still struggling to find an effective solution for it. Ghost spam creates absolutely fake visits without the need of bots or crawlers. It directly pollutes your Google Analytic by manipulating it statistics with unreal traffic. This way, you may see thousands of visits from the spamming site in your data, without actually having any.

What is referral spam used for?

Creating fake traffic is one sure way to make people curious and gain clicks and site visits back. Spammers use this method to make site owners visit the spamming page and in this way generate traffic and better ranking for themselves. By targeting thousands of websites and creating fake visits, the spammers effectively intrigue the website owners to personally click and check what this page that visits them so much is. This single action of curiosity is enough to create a huge traffic and promote the spamming site and boost up its ranking. This is a pretty unfair method to climb up in the ratings and Google is trying to restrict it as much as possible.

Does the Referral Exclusion List work for blocking Addons.Mozilla.Org?

A handy tool that probably most website owners have heard about is the Referral Exclusion List. Most people turn to it as a solution to the annoying referral spam and indeed it is, but only for the classic spam, which uses bots and crawlers. Handling Ghost spam, however, requires a different approach. In fact, using the Referral Exclusion List for handling Ghost spam is a terrible mistake and here is why. If you put Addons.Mozilla.Org in the list, the system will automatically try to trace back its visits. But the thing is that such visits have never happened since they are not real, but fake. That’s why the system will get confused and will mark them as real visits, this way counting them as traffic. Of course, this will pollute your statistics more, so we don’t recommend you use the exclusion list if you want to effectively solve the problem with Addons.Mozilla.Org. The removal guide below contains a different solution, which will offer you a better way to get rid of the spam. Give it a try and let us know about the outcome.
