If all or the majority of your content is word-for-word from someone else’s website, it is stealing if you don’t have permission and it IS duplicate content and even if you do not get punished for it, it still will not help you. It won’t count as added content. Those keyphrases someone else wrote won’t help you get ranked in the search engines. At best it’s a 0. At worst, you get banned by the search engines.

At least take the time to write some original content to go with it even if you do have permission to use the content. If you use 100 words of text, write at least 150 words of original content to go with it. That is bare minimum and necessary if you want to use content from somewhere else.

That’s my opinion and I’m sticking to it.
