Google says its will "begin to charge for clicks on directions in the same manner as clicks on your ad's headline or phone number." For AdWords campaigns with location extensions enabled, a "Directions" link can appear in advertisers' ads, as well as sponsored Google Maps info windows on desktops. On mobile search ads, a "Get directions using Google Maps?" pop-up will appear when users click on the expandable map. Clicking on "OK" in the pop-up allows users to get directions to advertisers' businesses.
