Checking Plagiarism, Copyscape

Copyscape, Website Plagiarism is something which you need to check, I could find an excellent site. This information was given to me by one of HomeJob Member, Mr Anirban roy. I needed to check my members submission before approval. 50% of the submissions which I get, are either copies from other websites or from any magazines. If you publish such contents, google marks those pages as supplemental results, because it could find similar pages on other websites

You can do 20 free checks a day or you can sign-up for an account and charge your account. They just charge, 5 cents for a check and its worth.

Use this if you need. I have an account with that and its really great

The other best method is to copy some text from the contents and paste it to Google Search Box and search, you will get the list of websites
