Google Ads is a lead-generation machine if used correctly, and a casino if not. Most service businesses click “Next” through Google's default setup wizard and wonder why they're getting calls for jobs they don't do.

The Short Answer

To set up Google Ads without wasting your budget, choose Expert Mode (not Express mode), build a Search campaign rather than accepting Google's default Performance Max wizard, and set up conversion tracking before you spend a single dollar. Then target high-intent local keywords with tight match types, layer in a strong negative keyword list, and review your search terms weekly. That combination is what separates ads that book jobs from ads that just burn cash.

The Fatal Flaw: Letting Google Auto-Configure Everything

When you first sign up for Google Ads, they'll try to push you into “Express” mode and then nudge you toward a default “Performance Max” campaign. Don't take the default path.

These default flows are designed to make Google money, not you. Express mode and an auto-configured Performance Max campaign give you almost no control over your keywords, almost no control over where your ads appear, and almost no visibility into what people are actually searching for before they click. Performance Max has its place once you have proven conversion data, but it is not where a service business should start.

Always use “Expert Mode.” It gives you the granularity needed to target high-intent customers while excluding the tyre kickers and DIY searchers.

Step-by-Step Lead Generation Setup

Step 1: Conversion Tracking First

Never spend a dollar until you can track where it's going. Set up conversions for form submissions, phone calls, and button clicks using Google Tag Manager (GTM).

Step 2: Target Intent, Not Keywords

Target “electrician Toowoomba” (high intent) rather than “how to fix a light” (informational). Use [Exact Match] and “Phrase Match” to keep things tight.

Step 3: Negative Keyword Lists

Exclude words like “free,” “cheap,” “jobs,” “salary,” and “DIY.” This prevents your ads from showing to people who will never pay your rates.

The Math That Matters

Target CPA

“What am I willing to pay for a lead?” If a $2,000 job has a 50% margin, you can afford a $200 lead.

Landing Page CTR

“What happens after the click?” Your landing page needs to load fast and have a clear CTA. No distractions.

It's Not Set and Forget

Google Ads isn't a “set and forget” system. It requires weekly optimisation: checking search terms, adjusting bids, and testing new ad copy.

If you don't have the time to manage it, don't do it yourself. You'll spend more in “learning tax” than you would in agency fees.

Frequently Asked Questions

Should I use Performance Max for my service business?

Not as your starting point. Performance Max spreads your budget across Search, Display, YouTube, Gmail, and Maps with very little visibility into where it's actually going. For a tradie or local service business, start with a tightly controlled Search campaign in Expert Mode so you can see exactly which search terms convert. Once you have real conversion data flowing in, you can test Performance Max as an addition, not a replacement.

How much should I spend on Google Ads to start?

Enough to gather meaningful data, which usually means a budget that can generate at least 15 to 30 clicks a day in your area. For most service businesses that lands somewhere between $1,500 and $3,000 a month. Spending less than that often means you never collect enough data to optimise, and you end up concluding “ads don't work” when the real problem was an underfunded test.

Why am I getting calls for jobs I don't do?

Almost always a negative keyword problem, or the result of letting Google auto-expand your targeting. Tighten your match types, build out a proper negative keyword list, and check your search terms report weekly to add new negatives as the junk shows up. Within a few weeks the irrelevant calls drop off sharply.
