When someone searches “plumber near me” or “electrician in [your town]”, Google shows a map with three businesses at the top. Those three spots — called the local pack or map pack — generate more enquiries than the rest of page one combined.
Google uses three core factors to decide who appears there: relevance, distance, and prominence. Most tradespeople have no idea this is how it works, which means they’re optimising the wrong things.
This article explains what each factor means, what signals feed into it, and the exact actions that move you up the rankings.
Key Takeaways
- Google ranks local businesses using three factors: relevance, distance, and prominence — understanding all three is how you beat competitors with more experience
- Prominence is the most actionable factor — reviews, website quality, citations, and posting frequency all feed into it
- Review velocity matters as much as total count — getting 3 reviews a month consistently beats getting 20 all at once and stopping
- Your website is a ranking signal for Google Maps, even if you’re not trying to rank organically — a weak or missing site pulls down your map pack position
- You can’t control distance, but you can influence which searches Google sees you as relevant for
How Google Decides Who Ranks in the Map Pack
Google’s local ranking documentation confirms the three factors:
| Factor | What It Means | Can You Influence It? |
|---|---|---|
| Relevance | How well your business matches what was searched | Yes — via profile completeness and category |
| Distance | How far you are from the searcher (or the location they specified) | Partially — service area settings |
| Prominence | How well-known and trusted your business is | Yes — this is the main battlefield |
None of these factors alone determines your ranking. Google combines all three. A highly prominent business that’s further away might outrank a closer one with fewer reviews and a thin profile.
Factor 1: Relevance
Relevance is how closely your Google Business Profile matches what the person searched for. If someone types “emergency boiler repair Glasgow” and your profile says “plumber” with no mention of boilers or emergency callouts, Google may not show you.
What feeds relevance
Primary and secondary categories
Your primary category is the biggest relevance signal. Choose it carefully:
| Trade | Correct Primary Category | What to Avoid |
|---|---|---|
| Plumber | Plumber | ”Plumbing supply store” |
| Electrician | Electrician | ”Electrical supply store” |
| Gas engineer | HVAC contractor | ”Heating contractor” |
| Roofer | Roofing contractor | ”Building contractor” |
| General builder | General contractor | ”Handyman” |
Add up to 9 secondary categories for everything else you do. A heating engineer who also does plumbing should add “Plumber”. A builder doing loft conversions and extensions should add both as separate categories.
Services section
The services you list on your profile are read by Google. If you offer bathroom installations, boiler servicing, and emergency callouts — list all three as individual services with 2–3 sentence descriptions each. Use the words your customers would type into Google.
Business description
You get 750 characters. Use them. Include your main trade, the areas you cover, any accreditations (Gas Safe registered, NICEIC approved, FMB member), and the types of work you specialise in. Don’t stuff keywords — write it naturally but make sure the key terms are in there.
Factor 2: Distance
Distance is the only factor you can’t fully control. Google calculates how far your business location (or service area) is from where the person searched.
What you can do
Set a specific service area
Tradespeople without a physical shopfront should hide their home address and set a service area instead. Go to your Business Profile → Location → Service area, and add every town, city, and postcode area you actually work in.
Don’t add areas just to expand your reach — Google is getting better at detecting this and it can hurt you. Set the area you genuinely work in, even if that’s just one city and the surrounding towns.
Use your location in your profile
Mention the towns you serve in your business description and in your service listings. If you’re a plumber covering Glasgow, Paisley, and East Kilbride, include those place names naturally in your content. This helps Google understand where you’re relevant.
Factor 3: Prominence
Prominence measures how well-known and trusted your business is — both online and offline. It’s the most complex factor, and the one with the most actions you can take.
According to Google, prominence is based on information gathered about a business from across the web: links, articles, directories, and reviews. A business with a well-established online presence will rank higher than an identical business that exists only as a bare GBP listing.
Reviews: the most visible prominence signal
Reviews are the clearest, most direct prominence signal available to a tradesperson. According to BrightLocal’s 2024 Local Consumer Review Survey, 87% of consumers read online reviews for local businesses — and businesses with more recent reviews rank higher in the local pack.
What matters about reviews:
| Signal | Why It Matters |
|---|---|
| Total number of reviews | More reviews = stronger prominence signal |
| Average star rating | 4.0+ is the threshold most customers trust |
| Review recency | A review from last week counts more than one from 2022 |
| Review velocity | Consistent new reviews beat a one-time burst |
| Owner responses | Responding to reviews is itself a ranking signal |
Review velocity is underrated. Getting 30 reviews in January then nothing for the rest of the year sends a weaker signal than getting 3 reviews every month consistently. Ask every happy customer — right after the job while you’re still on site. That’s when they’re most likely to do it.
How to ask without being awkward
Say: “If you were happy with the work, a Google review makes a massive difference to a small business like mine. Takes less than a minute.” Then send a follow-up message with a direct link to your review page. You can get this link from your Google Business Profile dashboard under “Ask for reviews”.
NAP consistency: the citation network
NAP stands for Name, Address, Phone number. Every time your business appears online — on Yell, FreeIndex, Checkatrade, your website — the details need to match exactly what’s on your Google Business Profile.
A plumber listed as “J. Smith Plumbing” on Yell and “J Smith Plumbing Ltd” on Google looks like two different businesses to Google’s algorithm. That inconsistency weakens the trust signal.
The minimum citation base for a UK tradesperson:
| Directory | Why It Matters |
|---|---|
| Yell.com (DA 78) | High domain authority, prominent in Google results |
| FreeIndex.co.uk | Trade-specific, do-follow link |
| Checkatrade.com | Industry-trusted, used by insurance companies |
| Thomson Local | Long-established UK directory |
| Bing Places | Powers Bing, DuckDuckGo, and some Apple Maps data |
Getting listed on 20–30 directories with consistent NAP is worth more for map pack ranking than most tradespeople realise. Each listing is a vote of confidence that your business is real and active.
Your website is a map pack ranking signal
Here’s something most tradespeople don’t expect: your website directly affects your Google Maps ranking.
Google crawls your website and uses what it finds to assess your business’s prominence. A well-built website with your services, service area, and trade body accreditations clearly stated tells Google more about your business. A missing website — or one that loads slowly and has no real content — is a gap in your prominence profile.
According to Moz’s Local Search Ranking Factors study, website signals account for roughly 16% of local pack ranking factors. For a new tradesperson trying to break into the top three, this is significant — a professional website can give you an edge over competitors who are relying on their GBP alone.
This is part of why services like Digital Tradies exist — a trade-specific website starting from £49/month, built and maintained for you, that does the technical groundwork to support your Google Maps ranking.
Google Posts: the activity signal
Google Posts are short updates you publish directly on your Business Profile — similar to social media posts but they appear in Google Search and Maps.
Posting consistently signals to Google that your business is active. A profile with a post from yesterday ranks higher than one last updated in 2023, all else being equal.
What to post:
- Photos of recently completed jobs (before and after)
- Seasonal availability (“taking bookings for central heating servicing this October”)
- Service reminders (“gas safety certificate season — book early”)
Aim for one post every week or two. It takes five minutes and the ranking benefit is real.
Photos: more than aesthetics
Profiles with more photos consistently outrank those with few. According to Google, businesses with photos receive 42% more requests for directions and 35% more clicks than those without.
For tradespeople, the most effective photos are:
- Before/after shots of completed work
- You and your van — establishes you as a real person
- Your equipment and certifications — builds trust
- The exterior of where you work from (if you have a workshop or yard)
Add a few new photos every month. Not because there’s a magic number, but because recency matters — it shows Google your business is active.
How to Check Your Google Maps Ranking
You can’t see your map pack position from inside your own GBP — Google shows you a customised result based on your location.
To see where you actually rank:
- Use a private/incognito browser window and search from a different device or location
- Use a VPN set to your target city to simulate a local search
- Try a rank tracking tool — BrightLocal’s Grid Tracker and Whitespark’s Local Rank Tracker both show how you appear across different points within your service area
The local pack results vary significantly by postcode. You might rank first for searches from one part of a city and not appear at all for searches from another part. This is normal — and it’s why getting your service area and website citations right matters.
Frequently Asked Questions
How long does it take to rank higher on Google Maps? Most improvements start showing within 4–8 weeks of consistent action — more reviews, updated photos, a complete profile. Getting into the top three map pack results from scratch typically takes 3–6 months, depending on competition and how active your competitors are.
Does having more reviews automatically rank you higher? More reviews help, but they’re one signal among many. A profile with 50 reviews, consistent Google Posts, full services listed, and a good website will often outrank a profile with 200 reviews and nothing else. The algorithm balances all three factors.
Can I rank on Google Maps without a website? Yes, but it’s harder. Google uses your website to verify and enrich information about your business. Tradespeople without a website are relying entirely on their GBP content and off-page signals (reviews, citations). A professional website fills a significant gap in your prominence score.
Why am I not showing up in the map pack at all? Common reasons: unverified GBP, wrong primary category, hiding your location without setting a service area, or operating in a highly competitive market with established competitors. Start with verification and category — these are the most common blockers.
Does paying for Google Ads help my map pack ranking? No. Google’s paid ads (Google Ads) and organic map pack rankings are separate systems. Running ads doesn’t improve your organic local ranking.
Where to Start
If you want to improve your Google Maps ranking this week, focus on these in order:
- Verify your profile is complete — every field filled in, correct primary category, services listed with descriptions
- Set your service area accurately — the towns and cities you actually work in
- Ask your last five customers for a review — with a direct link to your review page
- Add 5 new photos — recent job photos work best
- Publish a Google Post about your current availability or a recent job
- Check your NAP consistency — does your name, address, and phone match on Yell, Checkatrade, and your website?
