Google Ads cost per lead by industry: click costs and CPL estimates

A useful industry cost per lead carries four labels: market, period, campaign type and lead definition. We label ours, because without them it's a number, not a benchmark.

Our figures divide Keyword Planner bid ranges for Melbourne, in AUD excluding GST, by our standard enquiry rate. Four worked examples then let you test any figure against your own margins, through to a paying customer.

What counts as a lead in these figures?

Cost per lead is ad spend divided by leads. The arguments start with the second word.

A phone number click is not an answered call. A connected call is not a new qualified enquiry. A booking is not an attendance. A form from an existing customer asking for an invoice is not a lead at all.

Before comparing anything, define the lead. The industry table in this guide counts accepted enquiries.

Qualifying those enquiries and setting a target is a bigger job. Our guide to a good cost per lead for Google Ads covers it in full.

Google's reports count what you configured, not people. Google's conversion rate definition divides conversions by ad interactions. The page notes the rate can exceed 100%, because one click can produce several counted conversions. That happens when you track more than one conversion action or count every conversion.

Google's counting options let you count one conversion per click or every conversion, per action. Neither setting deduplicates a person across a call action and a form action. Person level deduplication is your job, in the CRM.

Those three tiles are one example cohort: $3,000 of spend, 30 enquiries, 20 qualified leads and 6 customers. The same spend produces a $100, $150 or $500 figure depending on which stage you divide by.

The stages also overlap. The 6 customers are among the 20 qualified leads, who are among the 30 enquiries. So adding the stages together would count the same people three times.

Where the industry numbers come from

Every industry figure you will read, including ours, comes from one of three places. The three don't mean the same thing.

Observed account data is spend and lead counts from real campaigns over a stated period. It's evidence. The sample, geography, channel mix and lead definition all need disclosing.

Historical bid statistics come from Keyword Planner's top of page bid ranges. The ranges approximate the 20th and 80th percentile of what advertisers paid over the last 30 days. They're neither your account's average CPC nor a forecast. Our guide to Google Ads keyword research covers how to pull and read them.

Assumed scenarios are arithmetic: a CPC input divided by an assumed enquiry rate. Useful for planning, worthless as a benchmark.

Blur the three and you get bad benchmarks. A calculated endpoint is a scenario, not an observed percentile. And the midpoint between two scenarios is not an average of anything. Any industry figure, ours included, should carry this disclosure.

Each line earns its place. An account count alone establishes neither precision nor national coverage. A Melbourne cohort is not Australia by default. Brand searches have to be split from non brand searches. Search partners, Performance Max and other channels have to be disclosed rather than blended in.

The sample should also include the accounts that did not work. The same goes for periods with no leads and accounts excluded for tracking faults. A table built from the winners is a highlights reel.

Weighting changes the answer. Account A spends $1,000 for 10 leads, a $100 CPL. Account B spends $9,000 for 30 leads, a $300 CPL.

Neither figure is a universal industry average. A few large accounts can also dominate a pooled ratio. The statistic has to say which question it answers. For that reason, the industry tables further down name their source and statistic.

For a pooled cohort, CPC is total spend divided by total clicks. The enquiry rate is total comparable enquiries divided by total clicks. Their ratio reconciles to the pooled CPL.

Medians of CPC, enquiry rate and CPL do not reconcile that way. Dividing a median CPC by a median rate does not give you the median CPL. Fractional attributed conversions are not counts of people either.

Timing matters as much as weighting. Google Ads reports conversions against the date of the click, not the date of the conversion. Google's page on how to understand your conversion tracking data explains this. So recent cost per conversion figures can look inflated until the lagging conversions arrive.

Compare mature periods. Say whether a report uses the interaction date or the conversion date. Keep later sales with the acquisition cohort that produced them.

There is no universal rule for when a sample is big enough. It depends on volume, variation and the length of the sales cycle. Then there's the promise to replace assumptions with data after two to four weeks. That's a promise about the calendar, not the evidence.

Foreign benchmarks need the same labels. A foreign figure isn't an Australian Google Ads figure, and converting the currency doesn't make it one. Blending it with local conversion rates produces a number with no sample at all.

Google Ads lead costs by industry

Every cost per lead in this section comes from one sum: the CPC divided by the enquiry rate. The chart below is the whole mechanism. It runs three CPC levels through our standard enquiry rate of 5% to 6%.

The ends of each bar are scenario endpoints, not quotes or observed results. Divide the CPC by the enquiry rate and you have the media CPL for that pair of assumptions. $10 at 6% is about $167. $10 at 5% is $200. And so on up the chart.

A $20 click at a 5% rate costs the same per lead as a $40 click at 10%. That is why the enquiry rate deserves as much attention as the bid.

The four rows below use the same inputs as the worked examples later in this guide. That way the numbers reconcile. Those inputs are examples, deliberately different from the Keyword Planner figures further down.

The useful unit is service intent, not the industry label. Use the sector guide below to decide what to separate and which lead stage to count. Do that before you compare anything with the tables further down.

Two placements matter. Training courses belong under education, not ecommerce. An online store is assessed on purchase acquisition cost, revenue and contribution rather than a lead cost. That's why no ecommerce row appears in either table. A store enquiry campaign can still use CPL, with a precise lead definition.

Lead definitions cause the most trouble in three sectors. See Google Ads for trades businesses, Google Ads for healthcare practices and Google Ads for professional services.

The tables below show what clicks cost in Melbourne, by service.

Each click range is Google Keyword Planner's top of page bid range for the main search. The ranges were pulled on 19 October 2026. Personal injury, wills and estates, commercial law and finance brokers are Australia wide. Each cost per lead divides that range by our standard enquiry rate of 5% to 6%. It's planning arithmetic, not a forecast for your account.

Trades come first. Emergency work tops the click ranges, because a burst pipe or a power fault can't wait.

Home and property services vary more. Renovation and removals can bid as high as trades, while fencing and landscaping stay low.

Cleaning, handyman work, photography and dental sit lower again. The dental ranges come from our own suburb targeted campaigns, not Keyword Planner. Bidding across a whole city can push a dental click past $19.

Legal searches carry some of the highest bids. Personal injury is the most expensive, and it climbs with the type of injury.

Accounting and finance round it out. Business loan searches bid far higher than general broker searches.

Source: Google Keyword Planner top of page bid ranges, pulled 19 October 2026. Ranges are for Melbourne unless a row says Australia wide. Dental ranges are from our own suburb targeted campaigns.

Statistic: estimated cost per lead divides the low bid by 6% and the high bid by 5%. The results are in AUD excluding GST.

A top of page bid range is wide on purpose. The low end is where the cheaper top of page clicks sit. In our experience, a relevant ad and landing page built for the search pull the cost towards it. Nobody can guarantee a click price, because the market sets it.

One pattern runs through the pairs. Emergency searches cost more per click than standard ones, in plumbing, electrical and dental alike. They often convert better too, because someone with a burst pipe rings the first business that answers. So the gap per lead can be smaller than the gap per click.

The chart lines up seven of those ranges. The spread inside one service is often wider than the gap between services.

Why costs vary within the same industry

The tables give one range per service. Two businesses in the same row and the same city can still have lead costs far apart. That can happen without either account being badly run. Before assigning a cause, match the comparison.

Service intent moves the number most. An emergency search and a general search for the same trade are different auctions with different conversion behaviour. A low value job and a major project share an industry label and nothing else.

Location changes competition and bids. Season changes demand. The only seasonal figure worth planning on is the one in your own account history.

Brand and channel mix can flatter or punish a figure. Brand searches from people who already know the business convert cheaply and belong in their own row. Search partners, Display, Performance Max and Shopping have their own cost profiles. They should be disclosed rather than averaged in.

Device mix, landing page quality, response time and the offer all move the enquiry rate. None of those is in Keyword Planner.

Read an unusual number as a question. An unusually low CPL can mean duplicate conversion actions counting one enquiry twice. Low quality enquiries, existing customers or heavy brand demand can do the same. An unusually high recent CPL can mean delayed conversions that have not arrived yet. It can also mean missed calls that were never counted, or a shift towards a more expensive service.

Check for duplicates before you celebrate a cheap lead. Our audit sample is 180 Google Ads account audits from August 2021 to September 2026. In about 1 in 3 accounts we audited, the Conversions column had a duplicate. It counted at least one enquiry or sale twice.

A zero conversion rate is a reason to investigate, not proof that tracking is broken. If the business takes enquiries by phone, check whether calls are counted at all, and how. Set up properly, call tracking for Google Ads is what puts those phone enquiries in the report.

One correction worth making plainly. Google states that Quality Score is a diagnostic tool and not an input in the ad auction. Google also says not to treat it as a key performance indicator.

Improving the displayed score does not mechanically cut your CPC. Nobody should promise that it does. Our guide to what Google Ads Quality Score actually affects covers what the components do mean for cost.

Four worked examples with the full maths

All four examples are made up. They are not Elev8d results, current prices or forecasts. Each runs the same spend through clicks, enquiries, customers and contribution. That lets you swap any input for your own and follow the working.

Contribution means what is left from the job after the direct costs of delivering it. Advertising, management fees and overheads haven't come out yet.

The multiple the chart shows is contribution against spend, not revenue ROAS and not net return. The $1,000 left after media still has to cover the management fee, the office and the owner's time.

The dental example does not work at a first visit contribution of $120. The tempting fix is to assume a 12 month lifetime value and declare success. That is not analysis. In healthcare, the fix also drifts towards modelling future treatment as the reason for the campaign.

Use only a retention period and a collected contribution the practice has actually evidenced. Keep bookings, attendance and appropriate care as the different outcomes they are.

High billings are not profitability. A big matter fee is not a big margin either. What counts is the contribution actually collected per matter, after the cost of the lawyer's time. The close rate from consultation to signed client counts too. This example sets it at two in ten.

The cleaner has the cheapest leads of the four and loses money. That's the point. A $60 CPL looks like a bargain until the job is a one off at a $100 contribution. And only three in ten quotes become jobs.

Cheap leads are not the goal. Affordable customers are.

The affordability test is one line.

Run the same test on the other three. The dentist's ceiling is $54 against a $150 CPL. The law firm's is $500 against $600. The cleaner's is $30 against $60. Only the plumber's leads cost less than the business can afford to pay.

Two corrections to the old examples, made explicitly because they were published. The old cleaner sanity check multiplied a $250 job by a 30% close rate. It called the $75 result gross profit. That figure is expected revenue per lead. Against an $80 CPL it is a $5 shortfall before a single job cost.

The old plumber had an $800 job at a 50% margin: $400 contribution before advertising. The same paragraph quoted a 60% to 80% close rate. At that rate, the media only break even CPL is $240 to $320. It isn't the $400 to $500 the article suggested. Those close rates are examples, not proven industry performance.

Revenue ROAS and contribution multiples are not net return on investment. Our guide to Google Ads ROI works through that in full.

Build a budget from your own figures

Once a campaign has run, replace every assumption above with your own observed CPC and enquiry rate. Then add the two numbers no platform report contains: the qualification rate and the close rate. Run a low, base and high scenario without attaching probabilities to them. That's because three chosen points are not a confidence interval.

Keep GST treatment consistent across spend, fees and contribution. Remember that media CPL excludes management, setup and other acquisition costs unless the label says otherwise.

Capacity belongs in the model. A budget that produces 40 qualified enquiries for a team that can serve 25 buys 15 disappointed prospects.

For growth, look at the cost of the additional customers. Don't assume the historical average holds when the spend rises. The next tranche of clicks tends to cost more and convert worse than the first. The same logic runs in reverse when a business cuts spend and keeps its best keywords.

Use the estimator's section for your own acquisition numbers, not its industry presets. The presets are planning assumptions, not measurements. Nothing on that page is a source for the table in this guide.

It estimates outcomes from the assumptions you give it. It is not a media quote or a market average.

For the wider cost picture, see our guide to how much Google Ads costs. It covers management fees and what a monthly budget buys.

Diagnose a gap before changing your ads

Say your CPL sits well above a figure you trust. The temptation is to start cutting bids and rewriting ads the same afternoon. Check the comparison and the tracking first.

The first branch catches false alarms. A figure for general searches compared against your emergency campaign. A cost per form compared against your cost per qualified enquiry. A 30 day window compared against a mature quarter.

The second catches tracking: duplicate conversion actions, uncounted phone enquiries and conversions still arriving for recent clicks. In the same audits, about 7 in 10 accounts had at least one fault in their conversion actions. That figure counts only the actions used for bidding or reporting. Not sure the counts are real? Check your Google Ads conversion tracking before you touch a bid.

The third is lead quality and follow up. No bid change fixes those. Only after all three do CPC and conversion rate become the question. Even then the service mix has to match before a difference means anything.

The optimisation itself is a bigger job. Our guides to a good cost per lead and to Quality Score cover it.

Handle data and regulated services carefully

Check Privacy Act coverage for your own business rather than assuming the small business exemption applies. The OAIC's small business guidance lists the exceptions.

Google's customer data policies also keep sensitive categories out of enhanced conversions and conversion uploads. Those categories include health, alleged crimes and divorce. So uploading patient records, criminal matter enquiries or separation enquiries to improve attribution is wrong. That goes for a dentist, a defence lawyer and a family law firm alike.

In health advertising, the TGA's guidance on advertising health services and cosmetic injections applies. It treats references to prescription only substances as advertising those medicines. Brand names count as references. Nicknames, acronyms and hashtags can too. The guidance judges the advertisement as a whole.

The ACCC's false or misleading claims guidance applies to benchmark and forecast claims in any industry. It covers an agency's claims about its own results too.

How the figures are reviewed and updated

Three dates belong on a benchmark page. They are not the same date. The data period is the span the figures cover. The extraction date is when the figures were pulled. The editorial review date is when someone last checked the page.

In this guide's tables, the click ranges are Keyword Planner's top of page bids for Melbourne. Their extraction date is 19 October 2026. The dental ranges come from our own campaigns. The UPDATED box at the top records editorial changes, not a new extraction.

Every refresh of the table runs the same loop, so one period can be compared with the next.

A change of search, location or rate breaks that comparability. When that happens, the page will say so rather than present the new figures as a trend.
