Here is an interesting site that I just discovered. http://www.copyscape.com You enter your website name in the site and it will let you know if there are duplicates of your website out there. I actually did not expect it to come up with anything. It did however pick up several sites, that I have duplicated my own content, as part of a promotional exposure.
Though interestingly I have found another consultant has duplicated part of my website. 22 words to be exact. She is not based in Queensland, so I am not to stressed, and I will take it as a form of flattery.
