Ways to earn money on product review website

I am stunning with your answer here. I have a review website and will change into tutorial website after read your suggestion.
the site still less than 4 months old and still struggling promoting it.
concentrate on generating traffic first/website promotion, money will follow when you have enough visitor (more than 1000 UV per day).

Thanks to all who’ve contributed.

It’s been over a month since the OP was here, so I think we can safely close the thread.
