As you write content in the Article Insights text editor or add research from the panel, the app keeps track of the uniqueness of the content.
It is important that the content you write is as unique as can be, to avoid search penalties.
In Article Insights this tracking is done for you automatically.
Check out the duplicates tab!
Any duplicate content in your article is highlighted in red.
Underneath you will also see a list of urls linking to the matched original content.
To make the content unique you need to re-write every 3 to 4 words.
