My website is similar to news.google.com. news.goole.com link's to original source, and shows some of the content from the target page. My website copies the content of the original source and shows users the copied content with a link to original source.
My question is will Google penalize my website as duplicate content? For SEO, what way is better: link to original source or show copied content to user?
My website language is Persian (Farsi), ca Google detect duplicate content in Persian language?
