The distinction is worth understanding because it explains a lot of confusion. Search results that list web pages are built from crawling websites. Map results are built from a database of businesses, and that database is populated by business profiles, licensing records, and data aggregators. Improving your website affects the first and has almost no direct effect on the second.
Start with your Google Business Profile, which is the largest source of map placement by a wide margin and the one most businesses have at least partially set up. Claim it if a listing already exists, which happens automatically for many businesses, and verify ownership through whichever method is offered. Verification is what converts a listing into something you control, and an unverified entry can be edited by other people.
Then do Apple Maps through Apple Business Connect, which many businesses never claim at all. Anybody using a phone that is not Android is using Apple Maps by default, and that is a substantial share of your local market receiving whatever information was assembled without your input. It is free and takes the same few minutes.
Bing Places matters more than its search share suggests, because that data feeds into several other surfaces and into some AI systems. Setting it up frequently allows importing from your existing profile rather than entering everything again, which both saves time and guarantees the two match.
Get the details identical across all of them, in exactly the same format. Name, address, and phone number appearing consistently is a signal these systems use to build confidence that you are one real business, and disagreement forces a guess. Write down the exact string you will use before starting, because the drift happens through retyping rather than through decisions.
Choose the primary category carefully, since it does more for relevance than anything else in the profile. Pick the most specific accurate option rather than the broadest one, and add secondary categories only for things you genuinely do. A business categorised generally competes with everybody in that general category.
Decide whether you are a business with a location customers visit or a service area business, because they behave differently. If customers do not come to you, hiding the address and defining the areas you serve is the correct setup, and it lets somebody working from home appear in local results without publishing a home address.
Then keep it current, which is where most listings decay. Hours including holidays, photographs added regularly rather than once, and any change to services or phone number reflected the day it happens. A listing with wrong hours costs you the customer who drove to a closed business, and that is the single most damaging ordinary error in this area.
Check what appears after a fortnight rather than immediately, since processing is not instant. Search for your business from a browser you are not signed into, and from a phone, because what you see while logged into your own account is not what a stranger sees.
Add the map to your own site as well, since somebody on your contact page is frequently about to travel to you and a working map removes a step. Link the address so it opens directions rather than only displaying a pin, because on a phone that single tap is the difference between somebody arriving and somebody copying an address into another application.
