Ask a few Australian business owners what they pay for a Google Ads lead, and you’ll probably hear very different answers. One might be happy with $30, while another considers $150 perfectly reasonable. Both could be right.

The problem starts when those figures are treated as a benchmark for every business. A number pulled from an article about another industry, another market or another year doesn’t tell you much about what your own advertising should cost.

Think about a cosmetic clinic in Sydney and a plumber handling blocked drains in Toowoomba. Both advertise on Google, but the work they sell is very different. One might bring in thousands of dollars from a treatment package, while the other charges a couple of hundred dollars for a callout. Their advertising costs need to be judged against those differences.

Key Insight:

The real question isn't how cheaply you can generate a lead. It's whether the enquiries you receive turn into enough profitable work to justify what you're spending.

Why the Average Cost Per Lead Figure Can Be Misleading

Industry averages can give you a rough starting point, but they rarely tell the whole story. The figures might combine businesses with different budgets, locations, services and ways of measuring a conversion. Some count phone calls as leads, while others count completed forms or enquiries that have been checked by a sales team.

That makes comparisons difficult.

Your Google Ads account operates in a particular market. The suburbs you cover, the services you offer, the businesses competing against you and the way you handle incoming enquiries all influence the result. An industry average cannot account for every one of those details.

There is another issue worth checking before you judge your costs: what does your account actually count as a lead?

A click on a phone number isn’t necessarily a completed call. A form submission might be spam, a duplicate enquiry or a request for work you don’t offer. If all these actions are counted as conversions, your dashboard can make the campaign look busier than the business really is.

Once you remove those misleading conversions, the cost per lead may increase. That doesn’t automatically mean your campaigns have become less effective. You may simply be measuring genuine enquiries more accurately.

Start by getting that number right. Everything else depends on it.

What Actually Changes Your Cost Per Lead

Several factors influence how much you pay for an enquiry. Some relate to the advertising auction itself, while others come down to what happens on your website and after someone contacts you.

Competition in your service area

A plumber advertising in inner Brisbane may face a different level of competition from one operating in Bundaberg. More businesses bidding for the same searches can push click costs higher, although the actual difference depends on the services and search terms involved.

Your location matters, but so does the area you choose to target. Advertising across a large region can bring in enquiries from people you cannot realistically service.

The searches you're paying for

Someone searching for an emergency hot water repair is probably looking for help now. Someone researching different types of hot water systems may still be comparing options.

Both searches can have a place in an advertising strategy, but they serve different purposes. If your main goal is to book jobs, the campaign needs to attract people whose searches match the services you’re ready to provide.

Your website and landing page

Getting someone to click an ad is only the first step. If the page takes too long to load on a mobile phone, makes the service difficult to understand or asks for too much information, people may leave without enquiring.

A clear page with a working phone number, a straightforward form and relevant service information gives visitors fewer reasons to abandon the process.

Keyword match types and negative keywords

Google Ads can match searches to your keywords in different ways. Without regular checks, your ads may appear for searches that have little to do with the work you want.

Negative keywords help exclude irrelevant searches. A business that only provides residential repairs, for example, may want to exclude searches relating to unrelated services or products it doesn’t supply.

When costs rise, lowering bids is an obvious reaction. Sometimes it is appropriate, but it won’t fix irrelevant traffic, a poor landing page or enquiries that never receive a response.

A Lead Isn't Always an Enquiry Worth Pursuing

A lead tells you that someone has made contact. It doesn’t tell you whether that person needs your service, lives within your coverage area or is prepared to pay your rates.

This is where advertising reports can paint a misleading picture.

Imagine a service business receiving 80 enquiries in a month at less than $40 each. The headline figure looks encouraging. But after reviewing the enquiries, the owner discovers that some came from outside the service area, others related to work the business no longer offers, and several were never followed up.

The campaign may have generated plenty of activity without delivering much useful work.

For a small team, those enquiries still take time. Someone has to answer the phone, return messages, ask questions and decide whether a job is worth quoting. That effort has a cost, even when it doesn’t appear in the Google Ads dashboard.

A better way to assess performance is to follow the enquiry through the sales process.

How many people asked for a quote? How many quotes were accepted? Which jobs were profitable? These details help explain whether your advertising is attracting the right customers.

If you make one change to your reporting this quarter, start recording which enquiries become quotes and which quotes turn into jobs. Our guide to measuring lead quality and return on investment explains how to approach this without making reporting unnecessarily complicated for a small team.

Work Backwards From What a Job Is Worth

Rather than starting with an industry benchmark, work out what your business can reasonably afford to spend to acquire a customer.

You’ll need three figures to begin with:

  • Your average job value.
  • The proportion of enquiries that turn into paying jobs.
  • The amount you can spend on customer acquisition while leaving enough margin to cover your other costs.

Consider a landscaping business where the average completed job is worth $4,000. If one in four qualified enquiries becomes a paying customer, the average revenue per qualified enquiry is approximately $1,000.

That doesn’t mean the business should automatically spend $1,000 to acquire each enquiry. Labour, materials, overheads and profit targets still need to be accounted for. But it gives the owner a more useful starting point than an industry average.

Now compare two campaigns. One generates enquiries for $40, but very few lead to a quote. The other costs $120 per enquiry and regularly produces jobs that suit the business.

The cheaper campaign isn’t necessarily the better investment.

The figures become more useful when you include the revenue and costs associated with the jobs won. A campaign that costs more to generate an enquiry may still deliver a stronger return if those enquiries turn into worthwhile work.

Why Cheap Leads Can Cost More Than You Think

Low cost per lead figures can be tempting, especially when advertising spend is already putting pressure on the budget. But the cost of a lead doesn’t stop at the amount recorded in Google Ads.

Someone still needs to deal with the enquiry. If your office manager spends hours responding to people who aren’t suitable customers, that time could have been spent arranging jobs, helping existing clients or following up genuine sales opportunities.

There can also be a mismatch between the work advertised and the work your team does best. A business might attract plenty of enquiries by offering a broad range of services, only to discover that many requests fall outside its experience, preferred job size or service area.

That creates extra quoting work without necessarily improving revenue.

Timing can make a difference, too. For Australian service businesses preparing for the busy pre-Christmas period, demand can rise alongside competition. Depending on the industry and location, that can put pressure on click costs and make it more important to focus on the enquiries that are likely to convert.

Instead of chasing the lowest possible cost per lead, look at the cost of winning a customer and the profit that customer brings in. That’s a much better basis for deciding whether your advertising is doing its job.

What to Check Before Cutting Your Budget

When the cost per lead goes up, reducing the advertising budget can seem like the quickest solution. Before making that decision, check where the extra cost is coming from.

Start with conversion tracking. Make sure the account is recording genuine enquiries rather than every click, page view or form interaction. If the underlying data is unreliable, decisions based on it will be unreliable as well.

Next, look through the search terms report. Are people searching for the services you provide, or are your ads appearing for unrelated queries? Add negative keywords where appropriate and review whether the targeting reflects the work you want.

Then test the website experience on a mobile phone. Does the page load properly? Can visitors see what you offer without scrolling through several screens? Is the contact form easy to complete?

You should also check how quickly enquiries are handled. A potential customer who calls three businesses may book with whichever one responds first. Paying for a good lead and then leaving it unanswered is an expensive mistake.

Once those areas have been reviewed, look at your bids, budgets and campaign performance. You may find that some services deserve more investment while others need tighter targeting or a different approach.

Campaign structure is part of that decision. If every service sits inside one campaign, it can be difficult to see which areas are using the budget and which are producing worthwhile work.

Our guide to the best Google Ads campaign structure for lead generation explains how to organise campaigns around the services you offer. If you’d prefer help managing the process, our PPC and Google Ads management services outline how we approach campaign setup, tracking and ongoing optimisation.

Key Takeaways

  • Industry averages are a starting point, not a target every business should follow.
  • Check that your conversion tracking records genuine enquiries.
  • Measure lead quality by following enquiries through to quotes and completed jobs.
  • Calculate an affordable acquisition cost using job value, conversion rates and business margins.
  • Consider the time spent handling unsuitable enquiries, not just the advertising cost.
  • Review search terms, landing pages and follow-up processes before cutting your budget.

FAQs

Q: Is a high cost per lead always a bad sign?

Not necessarily. A business that sells high-value services may be able to justify several hundred dollars for a qualified enquiry if enough enquiries turn into profitable jobs.

The important question is whether the cost makes sense for your business. If leads are becoming more expensive but the quality and value of the resulting work remain strong, the campaign may still be performing well.

Q: How long should I run Google Ads before judging the cost per lead?

There isn’t one timeframe that works for every business. You need enough reliable conversion data to identify a pattern rather than react to a handful of enquiries.

For some accounts, 30 to 50 recorded conversions can provide a more useful basis for reviewing performance than a very small sample. However, the number alone doesn’t guarantee a reliable conclusion. Conversion quality, sales cycles, seasonal demand and the type of service all matter.

If your business receives only a few enquiries each month, it may take longer to understand which changes are making a difference.

Q: Why did my cost per lead increase after we improved tracking?

Your previous figures may have included actions that weren’t genuine enquiries. Once duplicate submissions, accidental clicks and other misleading conversions are removed, the number of recorded leads may fall.

Your cost per lead can then rise even if your advertising spend and actual business results haven’t changed.

This is why consistent, accurate tracking matters. A higher figure based on genuine enquiries is more useful than a lower figure that overstates results.

Work Out What a Lead Is Worth to Your Business

Knowing what other businesses pay for Google Ads can be interesting, but it won’t tell you what your own campaigns should cost.

The more useful questions are how much revenue your enquiries generate, how many become paying customers and what remains after the costs of delivering the work are covered.

Once you understand those figures, decisions about advertising become easier. You can identify which services are worth promoting, where the budget is producing results and when a higher cost per lead is justified by better customers.

At XDesigns Advertising, we build and manage Google Ads campaigns for Australian service businesses, with a focus on meaningful tracking and results that connect back to real enquiries and jobs.

If you’re unsure whether your current advertising costs are reasonable, start with the last three months of data. Compare your ad spend with the enquiries received, the quotes accepted and the jobs actually won.

Those figures will give you a much clearer starting point for working out whether the issue lies with the cost of attracting customers, the quality of the enquiries or what happens after someone gets in touch.
