When you search something with local intent, like "plumber near me" or "coffee shop Wauwatosa," Google puts a small map at the top and lists three businesses under it with stars, hours, and a call button. That block is the Map Pack. It is the most valuable real estate in local search, because most people pick from those three without ever scrolling.
The three slots are drawn from Google Business Profiles, not from websites directly. Google decides who appears using three things: relevance (does your profile match the search), distance (how close you are to the searcher), and prominence (reviews, activity, and how well-known you are online).
Getting into the Map Pack is a different job from ranking a website. You can have the best site in town and still be invisible here if your Google Business Profile is thin, miscategorized, or short on recent reviews.
Search "barber Wauwatosa" on your phone. The three shops in the box with the little map? Those three are winning the category. Everyone else is fighting for the "More places" link almost nobody taps.
