Why create a fake duplicate / clone website?

...what is the reason for doing such a nonsense thing?

They might...

  • be associated with a competitor and want to take traffic away from your site. An exact clone of your site on another domain can only be detrimental to your sites SEO.

  • be trying to increase the value of their domain (an established site that receives lots of traffic), which they can then later sell on for a profit. Your site is just an unfortunate pawn in the process, selected because of its popularity.

  • be trying to serve malware to unsuspecting visitors by injecting malicious links/code into the cloned site. (Since the cloned site is relatively easy to setup and appears to be attracting a large number of visitors.)

It can also depend on the website, how it is being cloned and modified. They might also:

  • profit from changing the advertising network to one of their own.

The first thing you should do is report that website to google and other authorities secondly you should create a filter in google analytics that includes hits from only your hostname

Hope this helps,
