Duplicate content is the worst enemy for any site, and if Google founds duplicate content on your page, it can cost you a fortune. When the search engine indexes a website, it searches the content of the page and then compares the content to other websites that have been indexed.
The consequences of having duplicate content in your blog or your website are that it can be removed from the search engine, or its ranking can be disabled by the search engine for all the keywords you choose.
In view of the severe penalties in which your site may end up if its content is plagiarized, it is strongly recommended that you search for duplication of your current contents and any content you intend to post.
