Classic referral spam and ghost spam are forms of the same thing.These we employed by spammers with the intention of generating traffic for their websites by means of tricking other website owners into visiting them.
Over time, Google was able to put a stop to this but this led to the birth of a new and improved version of referral spam, to which Audit-seo.net belongs to – ghost spam. With this method the spammers go straight for your stats in Google Analytics and enter data in them. This creates the impression that you have been visited by the spamming website and in the end, you are prompted to see why this mysterious website is behaving in this odd way.
The activity of referral spam isn’t harmful to you; it doesn’t really affect you. The only thing it influences is your stats, and not your actual traffic count. However, if you think it important to keep a close track of your data, then the presence of things like Audit-seo.net can really mess that up for you.
