Are you spending money on Google Ads but not getting enough calls?
You are not alone. The average tradie wastes 30 to 40 percent of their ad budget. Those clicks never turn into jobs. That is real money leaving your account every day. And it is usually caused by a handful of settings.
This guide covers the most common Google Ads mistakes for service businesses in Australia. You will learn what each mistake costs you. You will learn how to spot it. And you will see what to do instead. The result? More jobs from every dollar you spend on digital marketing for tradies.
Mistake 1: Sending Ad Traffic to Your Homepage
This is the most expensive mistake in Google Ads for tradies.
Someone searches "emergency electrician Parramatta." They click your ad. They land on your homepage. It talks about your history, values, and six services. There is no clear next step.
That person hits the back button. You just paid $5 for nothing.
The fix: Build a dedicated landing page for each campaign. That page should match the exact search. If the ad says "emergency electrician," the page headline should say the same. One phone number. One form. One action.
A good landing page has four things:
- A headline that matches the ad
- Your phone number above the fold
- Three to five reviews from real customers
- One clear button: "Call Now" or "Get a Quote"
Your website speed matters here too. If the page takes three seconds to load, half your visitors leave. A fast, mobile-friendly site is not optional when you pay per click.
Why this works: Google also rewards good landing pages. It gives each keyword a Quality Score from 1 to 10. A higher score means you pay less per click. Landing page quality is one of the three factors in that score.
Mistake 2: Running Without Negative Keywords
Negative keywords tell Google what searches to ignore. Without them, your plumbing ad shows for the wrong searches. Think "plumber salary" or "how to become a plumber."
These clicks cost you money. Those people are not hiring anyone. They are students, job seekers, or DIY researchers.
The fix: Add a negative keyword list on day one. Here is a starter list for Australian tradies:
- Job-related: job, jobs, career, hiring, salary, apprenticeship, TAFE, course
- DIY intent: how to, DIY, tutorial, free, cheap, yourself
- Wrong location: add every city and suburb you do not service
- Wrong service type: add services you do not offer (e.g., "commercial" if you only do residential)
Check your Search Terms Report every week. It shows what people typed before clicking your ad. Every irrelevant search should become a negative keyword. This one habit can cut wasted spend by 30 percent or more.
Real example: A Sydney carpet cleaner was paying $8 per click. Half those clicks came from "carpet cleaning DIY tips." Adding "DIY" and "tips" as negatives saved $400 per month instantly.
Mistake 3: Using Broad Match Keywords Without Limits
Google Ads has three keyword match types. Broad, phrase, and exact. Broad match gives Google the most freedom. It shows your ad to anyone it thinks is relevant.
The problem? Google's idea of "relevant" is generous.
A Melbourne removalist using the broad keyword "removalist" triggers all sorts. "Removalist jobs Melbourne." "Cheap removalist tips." "Removalist insurance." None of those bring paying customers.
The fix: Start with phrase match or exact match. These give you more control over who sees your ads.
- Exact match: [removalist Melbourne CBD] shows ads only for that search
- Phrase match: "removalist Melbourne" shows ads for searches with those words in order
Only use broad match with a solid negative keyword list. Check the Search Terms Report daily for the first two weeks.
When broad match works: Once you have 30 or more conversions tracked, Google gets smarter. Its algorithm learns which searches convert for you. At that point, broad match paired with smart bidding can find new customers you missed. But never start there.
How Much Should You Spend? (Realistic AUD Ranges)
Here is what tradies in Australia should expect. These numbers come from real campaign data.
Cost per click (CPC): $3 to $12. It depends on your trade and city. Emergency plumbing and electrical cost more. Removalists and cleaners sit lower.
Monthly budget to start: $600 to $1,500 per month is sensible. That gives Google enough data to learn what converts. Below $600, you will not get enough clicks to measure.
Cost per lead: A well-run campaign gets leads for $20 to $60 each. If you pay more than $80 per lead, something needs fixing.
Break-even check: Work out what one new job is worth. Say the average job pays $500. You close one in four leads. That means you can spend up to $125 per lead and still profit.
Timeline: Give a new campaign at least four weeks before judging results. Google needs time to learn. Week one is always the most expensive. Costs drop as you add negatives and pause bad keywords.
If your numbers are worse than these ranges, the mistakes above are likely the cause.
Mistake 4: Targeting Too Wide an Area
A mobile mechanic in Brisbane does not need ads in Toowoomba. But if your location settings are on default, that happens.
Google's default shows ads to people "in, or interested in" your area. Someone in Perth searching "mechanic Brisbane" for a mate sees your ad. That click costs money and brings zero jobs.
The fix: Open your campaign location settings. Change "Presence or interest" to "Presence only." This stops ads showing to people outside your area.
Then set your radius tight. Most tradies service a 20 to 40 kilometre radius. There is no point advertising statewide. Target the postcodes where your customers actually live.
Bonus tip: If you service multiple suburbs, create separate ad groups. Write ad copy that names each suburb. "Electrician Cronulla" converts better than "Electrician Sydney." Locals trust local.
Mistake 5: No Conversion Tracking
This mistake makes all the others invisible.
Without conversion tracking, you cannot tell which keywords bring enquiries. You cannot tell which ads work. You are spending blind.
The fix: Track two things at minimum:
- Phone calls from your ad or landing page
- Form submissions on your landing page
Google tracks calls automatically with call extensions. Once tracking is live, give it two weeks. Then pause any keyword that spent $50 with zero conversions. Move that budget to keywords that bring leads.
A CRM that tracks lead sources makes this even clearer. You see which ad brought each call. You see if that call became a paying job.
Are You Checking the Right Numbers?
Most tradies look at clicks and impressions. Those numbers feel good but tell you very little.
The numbers that actually matter:
- Cost per lead: How much did one real enquiry cost?
- Conversion rate: What percent of clicks became enquiries?
- Quality Score: Google rates your ad relevance from 1 to 10. Higher scores mean lower costs.
- Search Terms Report: The actual words typed before the click
If conversion rate is below 5 percent, your landing page likely needs work. If cost per lead is too high, check negative keywords and location first.
Key Takeaways
- Never send ad traffic to your homepage. Use a dedicated landing page.
- Add negative keywords on day one. Check the Search Terms Report weekly.
- Start with phrase match or exact match. Broad match burns budgets fast.
- Set location targeting to "Presence only." Keep your radius tight.
- Track conversions from day one. You cannot fix what you cannot measure.
- Budget $600 to $1,500 per month for a proper test. Less is too thin.
- Check cost per lead, not clicks. Cheap clicks that never convert are not cheap.
- Give campaigns four weeks before judging. Week one is always expensive.
