I have a application which is based on Google Maps API. I would like to offer this application to other websites in iframe. Those other websites are all offering the same services like excavation and blasting works. My websites has also content about those same services. Now I would like to add Adsense into this application which is in iframe and are located in other websites. Is this allowed or its against TOS? Adsense which i would use is specially for made Google Map, its name Maps Ad Unit you can read more about it here https://developers.google.com/maps/documentation/javascript/advertising
