I'm not sure I can give much advice, but it might help for people to know what you think your target audience is and also what keywords you were using and what your ad text was. To me it seems like you just aren't reaching the people who have a use for your site. I think you need to reach people who have a need that is met by your site and will instantly realize the value. For instance, just an idea, but maybe you can find hard to pronounce names and use those as a keyword and have the ad be something like 'tired of people mispronouncing your name?'
