Syndicated content is content that is posted and re-posted many times on the web, on different pages of different websites. 

The search engines let their algorithm decide which page is the best for listing. This depends on a lot of factors, like how many back-link the page has, or how many social signals the page is receiving. So unique content is important. It needs more time and devotion, provides more value.
If you have similar contents with others, you will have to provide more value than the other pages, such as more feedback from your readers.
