I'm facing very strange situation with a few of my sites. I recently discovered that a few of my sites have been completely de-indexed by Google. When I went to check why this could happen, I discovered that quite a few other sites have stolen the content from my website (unique and written by me, sometimes with whole title and pictures included) and posted it to their sites which are still in Google's index.
I'm using a few different checking tools for duplicates, mostly CopyScape, Plagium and Plagiarisma. Do you have any other suggestion ? What tools do you use?
What can I do in general to prevent such situations happening in the future? I can't be 24/7 awake and checking duplicate content for all my sites, I hope you understand that.
Thanks for your time reading this and helping me out.
