You've optimized your ads, advertised to drive traffic to your site, and still no one's clicking. What's wrong?
If you find yourself asking that question, it's time you analyze your audience and understand why and how they come to your site and what they do there. You should start searching for keywords that lead to your site, pages visitors usually go to, amount of time they spend on the site, and other information that will help you understand who's clicking on the ads in your site and who's not and why.
