Do not copy content that is already published on your site or published on any other sites. Search engines may penalize your site or not rank your page if it has content that is copied or duplicated from other sites.
We will use each proposition and check all over the internet indexed website pages to see if that specific proposition already exists on any indexed page. You will get a list back with the found proposition and it’s first source we find, so you can rewrite it. This will help you be original in the eyes of google, and might give you a boost in rankings.
