i find article in my language and translate it into English language using google translator or other translator service, does this google we see as duplicate content if google check article Using their language translator i wonder this will effect SERP
Google won't bother translating the article so you are fine, unless someone else has already done the same thing as you. For the sake of anyone reading the article, just make sure it makes sense to read it in English.
no way will it hit the duplicate content filter. Google doesn't have its spiders reading pages the way a human does, it is simply looking at the words as basically a giant list. Your translated article is in good shape.
I want to know about article marketing and at the same time posting the articles to my own site. Is it possible that google takes my site with unique content?
