How to set up your Google Business Profile service area so you actually rank in the suburbs you serve

If you run a mobile trade, your Google Business Profile probably has a hidden address and a list of suburbs you serve. That setup is correct according to Google’s guidelines, but most trades assume the list is what determines where they rank. It is not. Google still calculates your proximity from your physical address, even when that address is hidden from the public. Listing 50 suburbs does not give you 50 suburbs of visibility. It gives Google a rough boundary for relevance, but proximity from your real address, your category, your reviews and your website authority decide whether you actually appear. A plumber in Epping who lists all of Greater Sydney is not competing equally in Bondi, Parramatta and Campbelltown. They are strongest around Epping and fade from there.

How does Google decide where to show my service area business?

Google uses three ranking factors for local results: relevance, distance and prominence. For a service area business, distance is measured from your registered physical address to the searcher, not from the edges of the suburbs you listed. This means your address is still the centre of gravity for your visibility, even though customers never see it. Relevance comes from your primary category matching the search query, and prominence comes from reviews, website authority and citations. The service area list tells Google which region you operate in, but it does not override proximity. A competitor with a closer address will outrank you in their neighbourhood even if you have stronger reviews and a better website. This is why two businesses offering the same service in the same city can have completely different coverage patterns across the suburbs they both claim to serve.

What is the right number of suburbs to list?

Google lets you add up to 20 service areas, and the sweet spot for most trades is between 10 and 20. List the suburbs where you genuinely work and want to win jobs, with your strongest areas first. Listing every suburb within a 100 kilometre radius does not improve your ranking in any of them. It just tells Google your service area is broad, which actually weakens the relevance signal for individual suburbs. Think of it this way: a search for “electrician Paddington” favours a business that serves Paddington and nearby suburbs over one that claims to serve the entire state. Google cross-references your service area with where your reviews come from, where your website mentions, and where your customers are located. If you list 50 suburbs but all your reviews are from three of them, that inconsistency tells Google the rest of the list is aspirational, not operational.

Why do I rank well near my address but disappear further out?

This is the most common pattern for service area businesses, and it is caused by proximity decay. Google gives the strongest ranking boost to businesses closest to the searcher. If your address is in Capalaba, you will likely rank in the top three across Capalaba, Alexandra Hills and Birkdale. By the time someone searches from Mount Gravatt or Sunnybank, 15 to 20 kilometres away, your proximity advantage is gone and local competitors with closer addresses take your spot. Most business owners never see this because they search from their own office or home, where proximity works in their favour. The only way to see the full picture is to check your ranking from dozens of locations across your service area at the same time, which is what a geo-grid coverage scan does. We regularly see businesses that rank first at their address and fall off the map entirely at grid points 10 kilometres away.

Can I improve my ranking in suburbs far from my address?

Yes, but not by adding more suburbs to your service area list. The levers that work at distance are prominence signals: more reviews (especially from customers in those suburbs), stronger website content targeting those areas, local citations that mention the suburb by name, and backlinks from local sources. A dedicated service page on your website for each key suburb, such as “Deck Builder Bulimba” with genuine local detail, reinforces relevance for that area. Review geography matters too. If you want to rank in Toowoomba but every review mentions Brisbane, Google has no evidence you actually serve Toowoomba. Asking satisfied customers in outer suburbs to mention the suburb in their review helps build that signal over time. None of this is instant. Strengthening your reach into a new suburb typically takes 8 to 12 weeks of consistent signals before you see movement in the Map Pack.

What should I check right now?

Log into your Google Business Profile, go to your service area settings, and audit the list. Remove suburbs you do not actively serve and make sure the suburbs where you want to win jobs are included, starting with your strongest. Then compare your list against where your reviews actually come from. If there is a big gap between the suburbs you claim and the suburbs your customers mention, that is the inconsistency Google sees. Finally, check whether you have service pages on your website for your top five target suburbs. If those pages do not exist, they are the single highest-value content you can add.

If you want to see exactly where your ranking holds and where it drops off, a local heat map shows your position at every grid point across your service area, suburb by suburb, so you know which areas need work.
