In other words, if you have 100 clicks, how many of those clicks should turn into buyers?

Going to depend on your site. I have just started my site and have had 40 hits and 2 sells. However, my clicks and impressions have stopped and they havent responded to my emails. If they dont respond I am going to cancel my service.http://www.tbirdsonline.com
