The complete guide to Google Ads for local businesses

Google Ads has one enormous advantage over every other channel available to a local business: the people clicking have already decided they want the thing. Nobody types "emergency electrician Adelaide" idly.

It also has a talent for spending money quickly and quietly on searches you never wanted. This is the plain-English version — what to run, what to skip, and what will actually decide whether it works.

Why it suits local service businesses

Most marketing has to create demand. Google Ads captures demand that already exists. If your business solves an urgent, searchable problem — a blocked drain, a cracked windscreen, a dentist on a Sunday — you're advertising to people at the exact moment they're ready to pay.

That's why cost per click looks expensive and often still works out cheap. A $12 click that converts one time in five gives you a $60 customer acquisition cost. Whether that's brilliant or terrible depends entirely on what a customer is worth to you, which is the number to work out before you open the account.

The campaign types, and the two that matter

Type	What it is	Verdict for a local business
Search	Text ads on results pages	Start here. Almost always the best money you'll spend.
Performance Max	Automated across all Google surfaces	Later, once you have conversion data. Not first.
Display	Banners across websites	Usually skip. Cheap clicks, weak intent.
Video	YouTube	Skip unless you have good video and a brand goal.
Demand Gen	Discovery-style placements	Not a starting point for a local service business.

Start with one Search campaign. Add anything else only when Search is working and you know what a conversion costs you.

Keywords and match types, in plain English

You're bidding on what people type. How loosely Google interprets that is the match type:

• Broad match — Google decides what's related. Widest reach, loosest interpretation, fastest way to spend money on the wrong searches.
• Phrase match — the meaning of your phrase has to be in the search. A sensible default for most local businesses.
• Exact match — that search, or a very close variant. Tightest control, smallest volume.

Start with phrase and exact. Add broad only when you've got a solid negative keyword list and conversion data to protect you.

Which keywords? The ones your customers actually type, which is rarely the language you use internally. That's a research job rather than a guessing job, and it's the same exercise as keyword research for SEO — the words are the same, you're just paying for these ones.

Negative keywords: the setting that saves the most money

Negatives tell Google what you don't want. Without them, a "plumber Adelaide" campaign will happily pay for "plumber apprenticeship", "plumber salary", "plumber near me free" and "how to fix a tap yourself".

Before launch, add the obvious ones: free, cheap, DIY, jobs, salary, course, apprenticeship, training, wholesale, second hand, and any competitor names you don't want to pay for. Then check your search terms report weekly for the first couple of months and add whatever nonsense you find. This single habit is the difference between an account that improves and one that just spends.

Nobody's first keyword list is right. The search terms report is where the real one gets written.

Budget, and how to think about it

Google spends to a daily budget and may exceed it on any given day, balancing out over the month. Set it at monthly total divided by roughly thirty.

The rule that matters: don't spread. One campaign with a workable daily budget will out-perform four campaigns on scraps, for the same reason a small Meta budget shouldn't be sliced up — the same logic as running Meta ads on a small budget. If your budget only covers one service, advertise the most profitable one and let SEO carry the rest.

Also use the settings that stop obvious waste: set your location targeting to "presence" rather than "presence or interest" so you're not paying for people in Perth reading about Adelaide, and run ad schedules if you only answer the phone during business hours.

Writing the ad

Responsive search ads take multiple headlines and descriptions, and Google mixes them. Give it fifteen headlines that are genuinely different from each other rather than fifteen variations of your business name.

Cover these angles: the service and the suburb, the proof (years, licences, reviews), the differentiator (same-day, after hours, fixed price), the objection (no call-out fee, free quote), and the action (call now, book online). Put your main keyword in a couple of headlines, because relevance affects both rank and cost.

And be specific. "Quality service, great prices" is what every competitor says. "Fixed-price quotes, same day in the eastern suburbs" is worth clicking.

Where the click lands

This is where most local accounts are actually lost. The ad is doing its job; the page it lands on isn't.

Send traffic to a page about the specific service you advertised, not your homepage. That page needs the same promise the ad made, above the fold, plus a phone number that's tappable, proof, and one obvious next step. Everything about what makes a small business website convert applies here, only more so, because you're paying for every visitor.

Page speed matters too — a slow page loses paid clicks you've already bought, which is the most annoying way to waste money there is.

Tracking, or you're just guessing

Set up conversion tracking before you spend anything. At minimum: form submissions, phone-call clicks, and booking completions. Without it you'll be optimising towards clicks, which is optimising towards nothing.

Link the account to Google Analytics, and while you're in that part of the world, make sure Search Console is set up too — it's the free view of what you're earning organically, which tells you where paid is genuinely adding something and where it's buying clicks you'd have had anyway.

Assets: the free real estate

Assets (Google still half-calls them extensions) attach extra lines to your ad at no additional cost per click, and they make your listing physically larger on the page. Skipping them is leaving space on the table.

The ones worth setting up on day one for a local business:

• Call assets — a tappable number, scheduled to your opening hours so nobody rings a dead phone.
• Location assets — linked to your Google Business Profile, which is worth having in order anyway.
• Sitelinks — four links to specific service pages, not "About" and "Contact".
• Callouts — short phrases: licensed, same day, fixed price, no call-out fee.
• Structured snippets — a list of your service types.

Twenty minutes of work, permanently applied to every impression you buy.

Bidding without overthinking it

Google will offer you a shelf of bid strategies. For a new local account the useful sequence is short.

Start on Maximise clicks with a sensible maximum CPC so nothing runs away from you, purely to gather data. Once you've accumulated a reasonable number of tracked conversions, switch to Maximise conversions, and only add a target cost per action once you know from your own data what a realistic target is.

The order matters. Setting a target CPA on day one, based on a number you invented, is how accounts end up throttled to almost no impressions while you wonder why nothing is spending.

The mistakes that cost the most

1. Using Smart campaigns. The simplified version hides the controls that make Google Ads work. Use the standard interface.
2. No negative keywords. Covered above, and it's the big one.
3. Sending everyone to the homepage. Also covered, also the big one.
4. Judging it in a week. Give it a month of data before big decisions.
5. Bidding on everything. Your most profitable service, done well, beats all six services done thinly.
6. Ignoring the search terms report. It's the only place the truth lives.

A sensible first 90 days

Month one: one Search campaign, one service, phrase and exact keywords, a decent negative list, conversion tracking live, a dedicated landing page. Change nothing for the first two weeks.

Month two: weekly search terms review, add negatives, pause keywords that spend without converting, write two more ad variations.

Month three: you should now know your cost per enquiry. If it's workable, add a second service or raise the budget gradually. If it isn't, the problem is usually the offer or the page, not the account.

What a healthy account looks like at six months

Useful to know what you're aiming at, because it's less impressive than people expect.

One or two Search campaigns. A handful of tightly themed ad groups, each with a small number of closely related keywords and its own landing page. A negative keyword list that's grown to a few hundred entries, most of them added one at a time from the search terms report. Conversion tracking that you trust. Two or three ads per ad group, refreshed occasionally. And a known cost per enquiry that you can quote from memory.

That's it. No sprawling structure, no hundreds of keywords, no clever hacks. Accounts that look complicated are usually accounts nobody has pruned.

Should you run it yourself?

Honestly, yes, if you'll give it an hour a week and you're comfortable in a spreadsheet. Google Ads rewards attention more than it rewards expertise, at least at local-business scale.

Where it goes wrong is the set-and-forget account: launched enthusiastically, never opened again, quietly spending on "plumber salary" for eight months. If that's the likelier outcome, either commit to the weekly habit or hand it over — the DIY versus agency question is really a question about which one you'll actually keep doing.

And remember paid is rented attention. It stops the day you stop paying. It works best alongside the slower, compounding work of local SEO — ads for the demand you need today, SEO for the demand you'd like to stop paying for.
