Ok, so basically i am interested in following. What if i create a website with some totally unique content, and some articles that are surly duplicated from word to word. How will search engines, especially Google, react to that site ? Is there some kind of percent, like if 50% of your site is unique then it is ok.. or something like that ? Will the whole site get penalized or only the pages that are duplicated. I am sorry if this is noob question, but i do not know exact answer to this question.
