Okay, it doesn’t work perfectly, but ever wondered who is copying your work and what they are doing with it? Even worse, want to know if someone is giving you attribution and know if someone is linking back to your site after taking an excerpt?
Although its not foolproof, Tynt is a start. It’s a service that automatically puts a link at the end of the copied text so if someone puts it in an email or on their website (and don’t delete the link) then you can track it. Tynt puts a tracking code at the end of the url and gives you a dashboard to track.
Cut and paste some text from this article to give it a test.
