Yes. Google Maps Ads can generate phone calls when the ad or promoted business profile gives customers a call option. Google Ads can also track calls as conversions, allowing you to measure how many calls your Maps advertising generates.
The important thing is that a phone call from Maps Ads is not automatically the same as a qualified lead. You should track whether the calls were relevant, whether the customer booked a job, and how much revenue they generated. That gives you a better picture of whether your Maps Ads are actually producing customers, not just calls.
