How Do I Know If My Google Ads Are Working?

Your Google Ads are working if your cost per lead or cost per sale sits below what that customer is actually worth to you, and that number holds up over enough volume to trust it. Impressions, clicks and engagement do not answer this question. Across the accounts we manage, most businesses asking "is this working?" are looking at the wrong numbers entirely.

We have managed Google Ads accounts across dozens of Australian industries, and the pattern is consistent. Businesses feel like their ads are failing when the real issue is that nobody set up the right numbers to check in the first place. This guide walks through exactly what to look at, what to ignore, and how long to wait before you judge anything.

Stop Looking at These Numbers

Impressions Don't Mean Anything on Their Own

Impressions tell you Google showed your ad to someone. That's the entire story. A campaign can rack up 50,000 impressions in a month and still produce zero leads. It's a visibility number, not a performance number.

Engagement metrics and "all clicks" are just as hollow. They measure activity, not outcomes. None of these numbers touch your bank account, so none of them should decide whether you keep spending.

High Impression Share With No Conversions Is a Warning, Not a Win

If Rank Math or your Google Ads dashboard is showing you dominating the auction with nothing to show for it, that's not success. It usually means you're showing up for the wrong searches, to the wrong audience, at the wrong stage of intent.

We've seen this exact pattern more than once. Ads showing constantly, budget disappearing daily, and a business owner assuming things must be working because "we're always on top." Read our guide to Google Ad Rank for more on what actually drives that top position and whether it's the right one to chase.

The Numbers That Actually Answer the Question

Cost per lead, or cost per sale if you're eCommerce, is the number that matters. Compare it against what a customer is genuinely worth to you. Not what feels like a "good" benchmark in general, but your actual margin and lifetime value.

Conversion rate tells you whether the people clicking through are the right people. A high click-through rate paired with a low conversion rate usually points to one of two problems: the ad is attracting the wrong audience, or the landing page is losing them once they arrive.

Volume Matters as Much as the Number Itself

One of our appliance repair clients in north-west Sydney generated 123 additional leads over five months at roughly $63 per lead, with 80% of those leads converting into actual jobs. That's a big enough sample to trust the number.

Five leads over five months at any cost per lead isn't a result. It's a data point that hasn't had the chance to become a trend yet. Don't make big decisions off small samples.

Read the Right Data at the Right Level

Never read Google Ads performance blended together with Meta Ads performance. The two channels behave completely differently, and blending them hides which one is actually doing the work.

Read by campaign, not just account-wide. A strong campaign can be quietly masking a weak one sitting right next to it in the same account.

If you serve multiple suburbs or regions, read the data geographically as well. We've seen accounts where one location was converting well while another was draining budget the entire time, invisible in the blended view.

  • Read by channel. Google intent-based searches behave differently to Meta's interruption-based feed.
  • Read by campaign. Account-wide averages hide underperformers.
  • Read by geography. One strong region can mask a weak one.

You generally need somewhere around $100 a day in spend before the numbers become statistically reliable enough to act on. Below that, you're often reacting to normal variation rather than a genuine signal. If you're still working out what a reasonable spend looks like, our guide to Google Ads costs in Australia breaks that down properly.

Give It Enough Time Before You Judge It

Search campaigns usually need 2 to 4 weeks of consistent spend before the data means anything, and longer again if your industry has a slower sales cycle. Google's algorithm also needs time to learn which searches convert.

Pulling the plug after four days because cost per lead looks high is one of the most common mistakes we see Australian businesses make. It's worth reading our guide on how long Google Ads actually takes to work if this is where you're at right now.

What "Working" Actually Looks Like

A Sydney carpet cleaning client we manage brought their cost per lead down from $108 to $70. Not through a clever targeting trick, but by methodically clearing out irrelevant search terms every single week.

That's what working actually looks like in practice. A number moving in the right direction over time, backed by enough volume that you can trust it wasn't luck.

A home renovation client in Adelaide came to us after 18 months of underperforming campaigns with a previous agency. Once we fixed their conversion tracking, which had never been set up correctly, leads increased 41% and cost per acquisition dropped 43% within three months. Sometimes "not working" isn't a strategy problem. It's that nobody could actually see what was happening in the first place. Our step-by-step guide to setting up Google Ads conversion tracking covers exactly what to check.

Frequently Asked Questions About Google Ads Performance

How long should I wait before judging if Google Ads is working?

Give it 2 to 4 weeks of consistent daily spend before drawing conclusions. Google's algorithm needs that runway to learn which searches actually convert for your business, and shorter windows are usually just noise.

What's a good cost per lead for Google Ads in Australia?

It depends entirely on your industry and what a customer is worth to you. A local service business might be comfortable at $60 to $100 per lead, while a higher-ticket service can absorb more. The number only means something when you compare it against your own margins.

Why are my Google Ads getting clicks but no leads?

This usually comes down to one of two things: the ad is attracting the wrong audience, so people click but were never going to convert, or the landing page is losing them after the click. Check your conversion rate alongside your click-through rate to see which one it is.

Can Google Ads work if I have a small budget?

Yes, but the data will take longer to become reliable. Around $100 a day is generally the point where results become statistically meaningful. Below that, focus on tight targeting and be patient with the timeline rather than judging results too early.

Not Sure If Your Google Ads Are Actually Working?

Reading Google Ads data properly is the difference between a campaign that's quietly failing and one that just needs another few weeks. We've helped Australian businesses go from guessing to knowing, including a north-west Sydney appliance repairer who landed 123 leads in five months at $63 per lead once the account was read correctly.
