According to Google Adwords, their click-through rate averages at only .4%. That is only 4 actual clicks per $1000 spent and not all of them will turn into customers. While getting traffic to your site may not result in income directly, just like marketing, it is still very worth it. This is because of the potential it has to make you money indirectly. Those indirect profits could come your way in the form of purchases or through ad revenue. It all depends on how you have your site set up.
