As The Next Web notes, Google believes the new ads will be "more attractive for users and more effective for advertisers".
Relevant ads on the Google Maps app can now appear at the bottom of the screen after a user performs a search. They include a title, ad text, and a link to get directions. Users can tap or swipe upward to see more information — this is a new click type known as “Get location details” and results in a standard CPC charge.Google Maps is a free download from the App Store.

When users click on an ad to get location details, they’ll see additional information such as the business’s address, phone number, photos, reviews and more. From here, there are a number of paid and free click actions they can take. Free actions include saving business information for later, sharing a business with a friend, or starting navigation. Aggregated reporting for these free clicks is available in your account.
