I am operating a website in China. In order to promote this site to our desired customers, we have taken the compagin of google adwords about 11 months. However, the effects of this seems not so good. We are puzzled why we don't achieve good effects.

Our website is selling dancewear/dance shoes. Our target customers are in Australia, UK, the USA, and singapore. Most of our customers are dancewear store owners or dance school owners. We just like kind of wholesale website.

I would very much interested to know when we should set the time for those countries? Is good to set 4 - 10 pm for Australia,UK, and USA in working days? How about a whole day for weekends?
