Cost per lead is one of the most useful numbers in your Google Ads account, and one of the most misunderstood. Business owners see a figure and ask whether it is good or bad, when the real question is whether it is good or bad for their specific industry, location, and the value of a customer.
This article breaks down what a realistic cost per lead looks like across common Australian industries, what drives that number up or down, and how to know whether yours is working for you or against you.
What is cost per lead?
Cost per lead (CPL) is simply how much you pay in ad spend for each enquiry your campaign generates. The formula is straightforward:
Cost Per Lead = Total Ad Spend / Number of Leads
If you spent $2,000 last month and received 20 enquiries, your cost per lead is $100. Whether that is acceptable depends entirely on what those leads are worth to your business. A tradie converting one lead into a $5,000 job has a very different equation to a retailer selling $40 products.
Average cost per lead in Australia by industry
Most global benchmark data is published in USD and based on US market conditions. Australian costs differ due to lower search volumes in many categories, different competitive landscapes, and geographic spread across major cities.
The figures below are drawn from WordStream’s 2025 analysis of over 16,000 campaigns and Studio Slate’s 2026 Australian market report, which cross-references Perth Digital Edge, Rocking Web, and MetricNexus data. USD figures have been converted at approximately $1.55 AUD.
| Industry | Cost Per Lead (USD) | Cost Per Lead (AUD approx.) | Conversion Rate |
| Automotive repair & service | $28.50 | ~$44 | 14.67% |
| Health & fitness | $62.80 | ~$97 | 6.80% |
| Dental services | $83.93 | ~$130 | 9.08% |
| Finance & insurance | $83.93 | ~$130 | 2.55% |
| Home services (trades) | $90.92 | ~$141 | 5.2%–7.33% |
| Real estate | $100.48 | ~$156 | 3.28% |
| E-commerce | $101.49 | ~$157 | 3.99% |
| Legal services | $131.63 | ~$204 | 4.2%–5.09% |
| Education & training | ~$55–$80 | ~$85–$124 | 11.38% |
| All industries (average) | $70.11 | ~$108 | 7.52% |

A few things stand out in this data. Automotive repair has the lowest cost per lead of any category, not because the clicks are especially cheap, but because the conversion rate is extraordinary. Nearly one in seven clicks becomes a lead, which is what happens when someone searching for a mechanic is already committed to booking.
Legal services sit at the other end. High cost per click driven by fierce competition, combined with longer consideration cycles, pushes the cost per lead above $200 AUD. But a single converted client in personal injury or family law can be worth tens of thousands of dollars, so the maths still works.
Why cost per lead varies so much
The CPL benchmarks above are averages. Your actual number will depend on several factors specific to your situation.
Your industry and keyword competition
High-value industries attract more advertisers bidding on the same keywords. More competition means higher cost per click, which directly raises your cost per lead unless your conversion rate compensates. According to WordStream’s 2025 data, legal services CPCs averaged $8.58 USD, while automotive repair averaged just $3.90 USD.
Your location
Australian costs vary significantly by city. Perth Digital Edge’s 2026 data shows average service industry CPCs ranging from $4.80 to $7.50 AUD in Sydney and Melbourne, down to $3.00 to $5.20 in Adelaide. A Geelong business will typically pay less per click than the same business in Melbourne CBD, which can be a genuine competitive advantage.
Your conversion rate
This is the variable most within your control. Two businesses in the same industry can pay identical CPCs but end up with very different costs per lead based on how well their landing page converts visitors. A page that converts at 10% produces leads at half the cost of a page converting at 5%, for the same ad spend.
Campaign structure and quality score
Google rewards relevance. A well-structured campaign with tightly themed ad groups, strong ad copy, and landing pages that match the search intent will achieve a higher Quality Score. According to data cited by Studio Slate from Adalysis and WordStream, a Quality Score of 10 can cut your cost per click by up to 50%, while a score of 1 to 3 can increase it by up to 400%. That directly flows through to your cost per lead.
So what is actually a good cost per lead?
There is no universal answer, but there is a framework that works for any business. The question to ask is not whether your CPL is low, but whether it is profitable.
Start with your customer lifetime value. How much revenue does a typical client generate over the course of the relationship? Then look at your lead-to-client conversion rate. What percentage of enquiries become paying customers?
From there, the maximum CPL you can afford becomes clear. If a client is worth $3,000 in gross profit, you close 1 in 5 leads, and you want Google Ads to account for no more than 20% of that revenue as acquisition cost, your maximum sustainable CPL is $120.
Here is how that plays out across three common Australian business types:
| Business type | Client value | Close rate | Max viable CPL |
| Geelong tradie (plumbing, electrical) | $1,500–$4,000 per job | 30–40% | $150–$400 |
| Allied health (physio, chiro) | $800–$2,500 (initial + ongoing) | 50–60% | $80–$250 |
| Professional services (accounting, legal) | $3,000–$20,000+ | 20–35% | $200–$1,400+ |
Most Geelong and regional Victorian businesses will find their industry CPL benchmarks sit well within a profitable range, particularly because local competition is lower than in Melbourne or Sydney. The benchmark averages above are largely driven by major metro markets.
How to bring your cost per lead down
If your cost per lead is higher than you want it to be, there are generally three levers to pull.
Fix the landing page first
This is the highest-impact change most businesses can make. An ad sending traffic to a generic homepage will almost always underperform compared to a dedicated landing page built around the specific search query. Clear headline, relevant content, fast load speed, and a single obvious call to action. If your page is converting at 2%, getting it to 5% halves your cost per lead without touching your bids.
Tighten your keyword targeting
Broad match keywords and poor negative keyword lists are the most common cause of wasted spend. If your ads are showing for irrelevant searches, you are paying for clicks that will never convert. Regular search term report reviews and an aggressive negative keyword list can significantly improve your conversion rate and reduce wasted spend.
Use retargeting
Most visitors do not convert on the first visit. Retargeting campaigns that follow up with people who have already shown interest in your business, at a much lower cost per click than search, can reduce your blended cost per lead substantially over time. It is one of the best returns available in paid advertising.
A note for Geelong businesses
The benchmark figures in this article reflect averages weighted heavily toward Sydney, Melbourne, and other major markets. Geelong businesses will typically see lower costs per click than these averages suggest, because fewer competitors are bidding on local terms.
That is a meaningful opportunity. A well-managed Google Ads campaign in Geelong can often deliver cost per lead figures well below the national benchmarks, while still reaching a high-intent local audience that is ready to act.
The key is making sure your campaigns are structured for local intent, your landing pages are built to convert, and someone is actively managing the account rather than leaving it on autopilot.
