The Maps versus App Store distinction is the whole post and it will be misread all week, because both live under the same brand and the same billing account.
Quick way to tell which one somebody is talking about: if the metric is taps to an app product page, it is App Store search. If it is a place card, directions or a call, it is Maps. The credits here are the second kind.
A shop, a clinic, a restaurant, a gym should look at this properly. An app with no address should close the tab.
