Your profile is the storefront. Your website is the back office.
On a phone, the profile is the whole decision. Name, stars, photos, hours, call button — most customers never reach your website at all.
Google picks which profile to show on relevance, distance and prominence. Categories and services drive relevance. Reviews and consistency drive prominence. Both are yours to control.
A profile set up once goes stale. Hours drift, categories go unused, and the competitor posting photos every week quietly takes the top slot. We run it as a channel, not a checkbox.
