Hello, I'm looking for a URL shortener that allows you to buy traffic that is targetted for specific interests or niches. Adfly only offers geo targetting. Clk.im may have sophisticated targetting capabilities but I haven't figured out how to use it as an advertiser. Do you know of such services? Thanks.
AdFoc.us offers the "capability to target regular expression matches *string* for referring URLs, operating systems, and browser names". It may be worth a try.
