How Google Decides Which Tradespeople to Show in Local Search Results

When someone types 'plumber near me' into Google, three businesses show up at the top. How does Google pick those three? It's not random, and it's not about who's been around longest. Here's how it actually works.

The three factors Google uses

Google has publicly confirmed that local search results are determined by three main factors:

Relevance: does your business match what they searched for?
Distance: how close are you to the searcher?
Prominence: how well-known and trusted is your business online?

Google has confirmed these are the three factors. Everything else is detail.

Understanding these three factors (and which one you can actually control) is the key to getting more local work through Google.

Factor 1: Relevance (does your profile match what they searched?)

Relevance is straightforward: Google checks whether your business category, description, and content match what the customer searched for.

If someone searches "emergency plumber" and your Google Business Profile lists your category as "Plumber" with "emergency callouts" mentioned in your description, Google considers you relevant.

If your category is "General Contractor" and your description mentions "building work", you won't show up for that "emergency plumber" search, even if you do plumbing work.

How to optimise for relevance:

Choose the right primary category. Pick the most specific one available (e.g. "Plumber", not "Home Services")
Add all relevant secondary categories. If you're an electrician who also does rewires, add both "Electrician" and "Electrical Installation Service"
Write a detailed business description. Include the services you offer and areas you cover, naturally worked into readable sentences
List all your services clearly. If you do boiler repairs, bathroom installations, and emergency callouts, make sure all three are mentioned

The goal is to help Google understand exactly what you do so it can show you to the right customers at the right time.

Factor 2: Distance (how close are you?)

Google prioritises businesses near the person searching. If someone in Manchester searches for a plumber, Google will show Manchester plumbers first, not ones in London.

You can't fake this. Geography is geography.

But here's what you can control: your service area settings.

Most tradespeople travel to their customers rather than having customers come to them. For service-based businesses like yours, Google cares more about your service area than your exact office address.

How to optimise for distance:

Set your service area correctly. List every town and postcode area you cover
Be specific about travel distance. If you cover 20 miles from your base, make sure Google knows this
Include neighbouring areas in your description: "Serving Birmingham, Solihull, Sutton Coldfield and surrounding areas"
Don't use a fake address. Google will penalise you if they discover you're using an address where you don't actually operate from

The broader your legitimate service area, the more searches you'll be eligible for. But don't claim areas you don't actually serve because customers will notice, and Google might too.

Factor 3: Prominence (how well-known and trusted is your business?)

This is the big one. This is where you have the most control, and where most of your effort should go.

Prominence is Google's measure of how established and trustworthy your business appears online. It's influenced by several factors, but reviews are by far the most important.

What affects your prominence:

Number of Google reviews: more reviews = more prominent
Average star rating: higher rating = more prominent
Recency of reviews: fresh reviews count more than old ones
Review velocity: a steady stream of reviews beats a one-time burst
Whether you respond to reviews: Google rewards businesses that engage with customers
Activity on your profile: posting photos, updates, and keeping information current
Your website and online mentions: backlinks, directory listings, and other websites mentioning your business

Reviews are the single biggest lever you can pull for prominence. Everything else is secondary.

A business with 60 recent reviews and a 4.7 rating will almost always outrank a business with 12 old reviews and a 4.3 rating, even if the second business has been around longer or has a better website.

This is why getting more Google reviews consistently is the most important thing you can do for local SEO.

The Map Pack: the only thing that matters

When someone searches for your trade locally, Google shows something called the "Map Pack": the top three local results with a map.

These three spots get the vast majority of clicks. Studies show that 75-80% of people click on one of these three results.

Below the Map Pack, there are more local results, but most people don't scroll down. If you're result number 4, you might as well be result number 400.

This is why local SEO for tradespeople is really about one thing: getting into those top three Map Pack results for searches in your area.

What you can do about it (practical action plan)

Now you understand how Google's local search algorithm works, here's your priority order:

Priority 1: Get more reviews, consistently

This has the biggest impact on your prominence ranking. Set up a system to request reviews after every job. Whether that's manual reminders or automated requests, consistency is key.

Aim for 2-4 new reviews per month, every month. This steady stream signals to Google that you're an active, current business.

Priority 2: Respond to every review

Google rewards engagement. When someone leaves a review, respond within 24-48 hours. A simple "Thanks for the review, John! Glad we got your boiler sorted" shows Google you care about customers.

Priority 3: Complete your Google Business Profile fully

Fill in every field. Add photos of your work, your van, your team. Write a proper business description. List all your services and service areas. The more complete your profile, the better it performs.

Priority 4: Add photos regularly

Google favours active profiles. Upload photos of recent jobs, your van, your tools, your team. Aim for 2-3 new photos per month.

Priority 5: Post updates to your profile

Google Posts let you share updates, offers, or recent work directly on your Business Profile. Use this feature monthly to show you're active.

Focus 80% of your effort on reviews. That's the highest-impact thing you can do for local search.

Frequently Asked Questions

How long does it take to rank in the Map Pack?

Typically 2-6 months with consistent effort, depending on competition in your area. If you're in a smaller town with fewer tradespeople, you might see results faster. In competitive cities, it takes longer.

The key is consistency. A few reviews every month for six months beats 20 reviews in one month and then nothing.

Can I rank in the Map Pack without a website?

Yes. Your Google Business Profile is what ranks in the Map Pack, not your website. Many successful tradespeople rank well with just a complete Google Business Profile and no separate website.

A website can help your overall online presence, but it's not essential for local search visibility.

Does paying for Google Ads help my local ranking?

No. Paid Google Ads and organic local search results are completely separate systems. You can't buy your way into the Map Pack.

Google Ads can get you immediate visibility while you build your organic presence, but they won't directly improve your Map Pack ranking.

What if there are already 3 strong businesses in my area?

The Map Pack isn't fixed. If you build more reviews and a stronger profile than the current #3 result, you can overtake them.

Businesses that stop collecting reviews eventually lose ground. Many established tradespeople rest on their old reviews while newer, hungrier competitors build fresh momentum.

Focus on consistent review collection and profile optimisation. Rankings change constantly as businesses get more or fewer reviews.

The bottom line

Google's local search algorithm isn't mysterious. It's based on three clear factors: relevance, distance, and prominence.

You can't change your location (distance), and optimising for relevance is a one-time setup task.

But prominence (driven primarily by Google reviews) is something you can improve every month for the rest of your business life.

Every review you collect makes you more prominent. Every response you write shows Google you're engaged. Every photo you upload signals that you're active.

Your competitors who understand this are already doing it. The question is: will you?
