Direct Answer
A Google Business Profile (GBP) is the free Google listing that controls how a business appears in Google Search, Google Maps, and the local map pack. Service businesses need one because 46% of all Google searches are local (Search Engine Land), and GBP is the single largest local-ranking factor.

“A Google Business Profile is the free Google listing that controls how you appear in Search and Maps. Every service business needs one.”
GBP is free; the only cost is the time to optimize it (categories, services, photos, posts, Q&A) and respond to reviews.
Service-area businesses (no walk-in storefront) can hide their address while still showing up in nearby map-pack results — set up service areas instead of a public address.
