Foursquare Measures Out-of-Home Ad Impact

Foursquare tracks location of its own panel of 10 million “always on” mobile devices. It has just extended its attribution reporting to include out-of-home media by tracking who comes close enough to an out-of-home display to have seen it. Since Foursquare can already track who visited a store, this new data lets it compare visits among exposed vs non-exposed groups.
