Now I am well aware that WA has site content and that when you publish content through site content that it checks for plagiarism.
However there are times when I personally need to check that content is unique before attempting to publish it.
Two good examples of this is when people send me guest posts to publish and when I hire a content writer.
For guest posts I need to ensure the content is unique before I approve it for publishing and request payment from the writer.
When I hire a content writer I need to check the content is unique before I make payment to the writer.
It is quick and easy to use and best of all it is free. I am a registered member on their site because I like to receive news and updates from them, however you don't have to register on their site to use their tools!
If you have any questions please leave them in the comments and I will come back to you soonest.
