ok these tactics does not work in Thailand i am asking to you Thailand forums.

It basically depends on what people are looking for. I would suggest you to keep on updating your blog with both , don't just stick to duplicate content. Keep on varying. If you find some good article or news that would attract more number of people then post else add original informative contnet.

I prefer to have an original and unique content rather than go for duplicate content. Ofcourse original is always better than fake.

unique content is best but if we use duplicate content traffic comes to us but ranking of our site will be less than original site where from you copy the content.

original content will definitely bring content to ur site and love from google too..
