As our search engine rankings have climbed, so has the amount of non-US traffic we receive. While we appeal to a worldwide audience, it's really just the US traffic that can be best monetized. Without giving away numbers, I really feel I need to do something drastic, and asap, to increase the percentage of US visitors. Any ideas?
I know Google Webmaster Tools has the ability to specify a geolocation to target traffic to, but we're a worldwide audience, and so it would be silly to be giving up free traffic for no reason.
