I am not familiar with this site so I looked at it.
From what I see it is like many sites. If you aren't paying for ads to have people visit you then your only hope is selecting good KEY WORDS, the ones MOST LIKELY someone would use TO SEARCH for whatever it is you are offering.
also adding words like:
bargain, cheap, exclusive
can catch a person's eye. Capital letters sometimes help. All these kinds of sites have a lot of competition so there is no easy answer.
