Duplicate content is a thorny issue but one thing you can be sure of, the more unique your content is, the better. For this reason, you need a way to check your text against what’s already out there on the net.

The reigning king of plagiarism checkers is Copyscape at You enter an URL and the software retrieves information about any duplicates out there. The free version limits you to ten results.
