When someone in your town searches "plumber near me" or "best roofer in [your city]," Google shows three businesses at the very top of the results, pinned to a map, with stars and phone numbers right there. Those three get most of the calls. Everything below them gets what's left.
That cluster is called the 3-pack. Getting into it isn't luck.
What the 3-Pack Is (and Why It Matters)
The 3-pack pulls from Google's local index: businesses with a Google Business Profile (formerly Google My Business) that Google trusts enough to recommend to the person searching.
Those top three results get about 40% of all local search clicks. The businesses ranked 4th through 10th split the rest. Anything below page one gets almost nothing.
For service businesses (HVAC, plumbing, electrical, landscaping, cleaning, contracting), the 3-pack is where the phone rings.
What Determines Who Shows Up
Google hasn't published a formula, but the signals are well-documented at this point. Four of them matter most.
1. How complete and active your Google Business Profile is
This is the big one. A half-filled profile is treated like a half-credible business.
Google wants to see:
- Accurate name, address, and phone number
- Correct business category (be specific: "Plumber" beats "Contractor")
- Hours, including any after-hours availability
- Photos that look real
- Regular activity like posts or responses to reviews
"Complete" doesn't mean you filled it out once in 2021 and forgot about it. Google tracks whether the profile is active. A monthly post, a response to a review, a new photo from a job site. These are small things that add up fast. The businesses sitting in the 3-pack in your area are almost always the ones keeping their profile current.
The profile is the foundation. Everything else builds on it.
2. Reviews: how many, how recent, and how you respond
Google weighs reviews as a trust signal. Not just the number of them, but how recent they are and whether you respond. A business with 12 reviews from the last six months will usually outrank one with 50 reviews from four years ago.
Responding to reviews, good and bad, signals that a real person is running this business. That matters to Google and to customers reading them.
3. Local signals on your website
Your website backs up your Google Business Profile. If your GBP says you're a plumber in Gadsden and your website never mentions Gadsden or plumbing anywhere in the text, that's a disconnect Google notices.
Your city and services should appear naturally in your page titles, headings, and body text. It doesn't take much. A dedicated service page for each city you work in goes a long way.
4. Proximity to the searcher
Google factors in how close the searcher is to your business address. You can't move your shop, but you can make sure your address is accurate and consistent everywhere it appears online. Inconsistencies confuse Google.
The Most Common Reason Businesses Are Invisible
Most service businesses that don't show up in the 3-pack never claimed their Google Business Profile in the first place. Google often creates a basic profile automatically when it finds a business mentioned online, but unclaimed profiles can't be managed, don't show accurate information, and tell Google nothing about who's running the place.
The ones who did claim it usually filled out the name and phone number and never touched it again. No photos, no reviews, no activity for years.
Either way, it's fixable in a day.
Where to Start
If you haven't claimed your Google Business Profile, go to business.google.com and do that first. It's free and takes about 15 minutes.
Once you're in:
- Fill out every section: category, description, hours, services, attributes
- Upload at least five real photos (your vehicle, your team, a job site, your storefront if applicable)
- Ask your last five customers for a review. Text them the direct link, don't just tell them to "leave a review"
- Post something once a month: a completed job, a seasonal tip, anything that shows the profile is active
Then look at your website. Does it mention your city? Your services? Your service area? Those pages are what your GBP points to, and they need to hold up.
None of this is complicated. The hard part is just sitting down and doing it.
