The Problem of Creating Unique Content.
If you run a website or blog, you may know that getting fresh content is really important. But generating articles is that not so many people love to do (it's boring and it takes a lot of time). That's why multiple people commit the mistake of using “free articles”. This substitute sounds good but it has something negative to remark: you'll be using not unique content.
Duplicate Content: Something That Google Hates.
Just one free article may be utilized by tons of other sites, generating many dupe content (thing that google hates).
And if they catch you with a immense % of not unique content, your site might be moved to the page 3.000.000 (duplicate content penalty). Nobody wants this.
