How Does Google Pick the 3 Businesses in the Map Pack?

Google decides which three businesses show up in the map pack using three factors: relevance (how well you match the search), distance (how close you are to the person searching), and prominence (how well-known and trusted Google thinks you are). You can't do much about the first two — but prominence is built from things like reviews, business directory listings, and your website, and that's the one you can actually work on.

Picture a plumber in Ballarat. A pipe's burst under someone's kitchen sink and they grab their phone and type "plumber Ballarat." Three businesses pop up under a little map, each with a star rating, a review count, and a "call now" button. That's the map pack. Most people never scroll past it — they pick from those three, or maybe glance at one more before deciding. If your business isn't one of those three, you've basically gone invisible to that panicked homeowner, no matter how good your work actually is.

Why the map pack matters more than your ranking anywhere else

For a plumber, sparky, hairdresser or café, the map pack is the moment that decides whether the phone rings. Someone searching "plumber Ballarat" isn't researching — they're about to hire someone, usually within the hour. Google knows this, so for these kinds of "near me" searches, it leans hard on local results instead of the regular list of websites further down the page.

That's where relevance, distance and prominence come in. Relevance is Google checking that your business actually does what's being searched — a plumber shows up for "plumber," not "electrician." Distance is roughly how close your business address is to the person searching, or to the suburb they typed. Neither of these is something you can nudge much day to day; your trade is your trade, and your workshop is where it is.

Prominence is different. It's Google's best guess at how well-established and trustworthy a business is — and it's built almost entirely from things you can go and change this week.

What "prominence" actually means, in plain terms

Prominence is Google cross-checking your business against everything it can find about you on the internet. The biggest piece is reviews — both how many you have and how good they are. A plumber with 40 reviews and a 4.8 star average is going to beat one with 3 reviews every time, even if the second plumber is technically closer to the customer. Google treats a wall of reviews as evidence that real people trust you.

The next piece is what's called citations — that's just a fancy word for your business name, address and phone number showing up consistently across the web: on directories like Yellow Pages or Yelp, on trade association listings, on local Ballarat business groups. If your address is listed one way on Google and a different way somewhere else, it makes Google less confident you're a real, stable business — and confidence is exactly what prominence is measuring.

And then there's your website. This is the part that trips people up, because the map pack looks like it's "just Google Maps" — no website in sight. But Google's algorithm looks at your website behind the scenes to work out what you do, how long you've been doing it, and whether other legitimate pages link to you or mention you. A business with a real website, filled with your suburb names, your services, and some proof of past jobs, gives Google far more to work with than a business that only exists as a pin on a map. No website means Google's working with almost nothing — and it shows up as lower prominence, even if your work is excellent.

What good looks like for a trade business

A basic website earns its keep here by doing a few specific things well. It should clearly list the suburbs and areas you cover — Ballarat, Sebastopol, Wendouree, wherever your van actually goes — because Google matches that text against what people search. It should list your services in plain language, not just "plumbing" but "hot water repairs," "blocked drains," "gas fitting," since those are the exact phrases customers type. It should have your phone number and business hours somewhere obvious, and ideally a page or two of finished jobs or customer photos, because that's the kind of thing that makes both Google and a nervous customer trust you're the real deal.

None of this needs to be flashy. It needs to exist, be accurate, and match what your Google Business Profile says.

The excuses, and where they hold up

"It costs too much" — a basic website is a lot cheaper than it used to be, and compare it to what one missed emergency call-out is worth. "I'm not technical" — fair, and you shouldn't need to be; tools exist now that build a website straight from your existing Google listing. "I get enough work from word of mouth" — that might be true today, but word of mouth still ends with someone Googling your name to check you're legit before they call, and if nothing comes up, some of them will quietly ring the next plumber instead.

These objections aren't silly. They're just solvable with less effort than most business owners assume.

What to do this week

Start by checking your Google Business Profile is accurate — right address, right phone number, right hours, right service areas. Then ask three past customers for a review; that alone can shift you into the map pack for searches you're currently missing. If you don't have a website, or yours hasn't been touched in years, that's the other lever worth pulling — it's quietly feeding Google's sense of how prominent you are, even though it never appears on the map itself. You can get a free website preview built straight from your existing Google listing, no technical knowledge required, and see what it'd look like before you commit to anything.
