How to run Google Ads without setting money on fire

The default settings are designed for Google, not you

When you click "Create campaign" in Google Ads, the wizard cheerfully nudges you toward broad match keywords, automated bidding, "maximise clicks," display network on by default, and a daily budget that quietly multiplies during the month. That setup is fantastic for Google's revenue. It's how small business budgets get drained in two weeks on searches that were never going to convert.

Google Ads can be one of the best growth channels a small business has — when it's set up by someone who knows where the trapdoors are. It can also be the single fastest way to lose R20,000 with nothing to show for it. The difference is mostly about defaults.

What you're actually buying

You're not buying clicks. You're not buying traffic. You're buying intent at the moment of decision. Someone who types "emergency electrician Bellville" is hours, not weeks, away from spending money. Your job is to put a credible, obvious answer in front of them at the moment they ask. That's it.

This framing changes everything. You stop caring about CPM, impressions, "engagement," and start caring about one number: cost per qualified lead (or cost per sale, if you can measure that far down the funnel).

A safer starting structure

If you're setting up an account from scratch — or auditing one that's bleeding — start here:

Match types: phrase or exact only

Broad match is Google's default. It's also the single biggest reason small accounts burn cash. Broad match for "plumber Cape Town" will happily show your ad for "plumber jobs", "DIY plumbing", "plumber salary", "plumbing courses" and dozens of other searches that will never call you. Stick to phrase and exact match until you have at least 30 conversions and real data to expand from.

A real negative keyword list, from day one

Before you spend a cent, build a starter negative list: free, jobs, salary, course, training, DIY, how to, cheap, second hand, reviews, complaints. Add to it weekly based on the search terms report. This is the single highest-ROI 15 minutes you'll spend on the account each week.

One landing page per ad group

Sending every click to your homepage is wasted spend. If the ad promises "Emergency Geyser Repair, Northern Suburbs," the click should land on a page that says exactly that — not a generic homepage with a tiny "services" menu the visitor has to hunt through. Quality Score improves, cost per click drops, conversion rate rises. Triple win.

Manual or "Maximise conversions" bidding — not "Maximise clicks"

"Maximise clicks" is a polite way of saying "spend my entire budget on whatever traffic is cheapest." Until you have conversion data, use manual CPC with sensible caps. Once you have 30+ conversions, switch to Maximise Conversions or Target CPA.

Search network only at first

Turn off the Display Network, YouTube and Search Partners until you know exactly what each is costing and contributing. They're on by default. They shouldn't be.

Track real conversions, not page visits

A conversion is not a click, not a page view, not a "session of more than 30 seconds." A conversion is a form fill, a phone call from the ad, an actual purchase. Set up:

• Phone call tracking (Google can dynamically swap your phone number on-site to track which calls came from ads).
• Form submission tracking via Google Tag Manager.
• Offline conversion import if your sales close on the phone or in person — this is the cheat code most SMBs never enable.

Without proper conversion tracking, you're guessing. Google's bidding algorithms are guessing too, and they default to optimising for clicks because that's all you've given them.

The 30-minute weekly audit

Block 30 minutes every Monday. Open three tabs:

1. Search terms report. Scan the last 7 days. Anything irrelevant → negative keyword.
2. Conversion column. Anything spending money with zero conversions over 14+ days → pause and investigate.
3. Top of page bid simulator. Are you over-paying for positions that don't convert better than position 3?

That's the whole audit. Do it religiously for two months and your cost per lead will roughly halve.

Set a tripwire before you start

Give every new campaign a strict daily cap, a clearly defined "this counts as a win" number (e.g. "under R350 per qualified lead"), and a 14-day review date in your calendar. If the unit economics aren't there at day 14, pause and rethink — don't let it bleed for "another month to gather data". That month rarely fixes the underlying problem and almost always doubles your loss.

Common mistakes that drain budgets

• Letting Google "recommend" auto-applied changes. Turn auto-apply off. Every single recommendation is reviewable, and most are wrong for small accounts.
• Geo-targeting "people in or interested in" your area (the default) instead of "people in your area." The default shows your ads to people researching your city from anywhere on the planet.
• Running ads to a homepage that loads in 6 seconds. Page speed isn't just SEO — it's a Quality Score input.
• No ad extensions. Sitelinks, callouts, structured snippets, call extension, location extension. Free real estate, higher click-through, lower CPC.

What to do this week

1. Pause every broad match keyword in your account.
2. Build your starter negative keyword list and apply it account-wide.
3. Turn off Display Network, YouTube and Search Partners on every Search campaign.
4. Confirm conversion tracking is actually firing — submit a test form and check it shows up.
