What is a good cost per lead from Google Ads?
A good cost per lead is one that leaves you profit once you know what a lead is worth to you. US benchmarks put the 2025 average at $70.11, but your own maths decides what is good for you.
A good cost per lead is one that leaves you profit once you know what a lead is worth to you. Across more than 16,000 mostly US campaigns, WordStream’s 2025 benchmark puts the average at $70.11, with industries running from about $28 to $132. Use those as a sense check, not a target. Your maths decides what is good for you.
Most owners ask us this question after a few months of spend, when the invoice is real but the enquiries feel vague. The honest answer has two parts: what other businesses pay, and what you can afford to pay. The second matters far more than the first.
What a cost per lead actually is
Cost per lead is simple: what you spent, divided by the leads you got. Spend £600 in a month and get 10 enquiries, your cost per lead is £60. It only makes sense against your advertising objectives: if the objective is enquiries, the lead is the unit that matters, not clicks or impressions.
The catch is what Google counts as a lead. Google Ads only knows what you tell it to track. If your conversion tracking counts a button click, a page view or a 10-second phone call as a “lead”, your reported cost per lead looks lovely and means nothing. Before you judge the number, check what sits underneath it. A lead should be a real enquiry: a phone call from a person, a completed form, a booking. Google’s own conversion tracking setup is where that gets defined, and getting it right is the first job.
What other businesses actually pay
The most useful public benchmark is WordStream’s 2025 Google Ads data, built from over 16,000 campaigns. It is mostly US data in US dollars, so treat it as a shape, not a tariff for your business.
| Industry group | Average cost per lead (2025) |
|---|---|
| Automotive repair, service and parts | $28.50 |
| Restaurants and food | $30.27 |
| Arts and entertainment | $30.27 |
| All-industry average | $70.11 |
| Business services | $103.54 |
| Furniture | $121.51 |
| Attorneys and legal services | $131.63 |
Two things to take from that. First, the spread is enormous: a legal lead costs four times a car repair lead, because one signed client is worth thousands. Second, costs have risen for five years running, though 2025’s rise was modest at around 5% after the previous year’s 25%. If your cost per lead has crept up, you are not imagining it, and it is not automatically your agency’s fault. WordStream updates the benchmark every year, so check the latest edition before you quote these numbers back at anyone.
The only maths that matters
Forget the averages for a moment and work out your number. Take your average job value, multiply by the share of leads you turn into paying customers, and you have what a lead is worth before costs.
Say your average job is £1,000 and you win one in four enquiries. Each lead is worth £250 of work. A £60 cost per lead is fine: you spend £240 on ads to win £1,000 of work, and your margin decides whether that is healthy. Now picture a £150 job with the same one-in-four close rate. A lead is worth £37.50, and a £60 cost per lead loses you money on every enquiry. Same number, opposite verdict.
This is why “what is a good cost per lead?” has no single answer. A £120 lead is brilliant for a solicitor and a disaster for a dog groomer. Anyone who quotes you a universal figure is guessing.
Why your cost per lead might be high
When we audit accounts that feel expensive, the same handful of causes turn up again and again:
Tracking is flattering the account. Junk conversions (button clicks, page views) hide the real figure, or genuine phone leads are not counted at all, which makes the cost per lead look worse than it is.
One blended number hides the detail. Read campaign performance campaign by campaign in Ads Manager, not as one account average. Whatever the campaign type – Search, Performance Max, Display – each earns its own cost per lead, and the expensive one is usually obvious once you look.
The targeting is too broad. Broad keywords match searches that were never going to buy. The search terms report shows what you actually paid for, and it is often an eye-opener.
The landing page wastes the click. A slow page, no clear phone number, or a form buried three scrolls down turns paid clicks into nothing. Doubling the page’s conversion rate halves your cost per lead without touching the ads. If you are not sure what your page should be achieving, see what is a good conversion rate and what is a landing page, and does my small business need one.
The market is genuinely expensive. Some sectors simply cost more, and costs have risen across the board. In that case the answer is better conversion, not cheaper clicks.
How to bring it down
Work through them in order. First, fix tracking so every real enquiry is counted and nothing fake is. Second, read the search terms report and add negative keywords for the searches you would never want to pay for – a negative keyword simply tells Google “never show my ad for this”, and a handful of them usually cuts wasted spend within days. Third, tighten the landing page: one page, one service, one obvious way to enquire. Fourth, review bids and budgets only after the first three are done, because bidding harder on a leaky funnel just buys leaks faster.
If someone manages the account for you, these are exactly the questions to ask them. A good manager welcomes them and shows you the search terms without being asked twice.
Where to start, in one table
| What you see | Most likely cause | First fix |
|---|---|---|
| Lots of conversions, few real enquiries | Tracking counts junk actions | Redefine conversions around calls and forms |
| High spend, irrelevant enquiries | Broad keywords, weak negatives | Search terms report, add negatives |
| Good click numbers, poor lead numbers | Landing page losing people | Speed, phone number, simpler form |
| Steady lead flow, rising cost per lead | Market costs climbing | Improve conversion rate before cutting budget |
| No idea which number is real | No call or form tracking | Proper tracking before anything else |
Is Google Ads even the right place for the money?
Worth asking before you obsess over the number. If most of your cost per lead problem is that nobody searches for what you sell, cheaper clicks will not save you. A few neighbouring questions worth an honest answer: are competitors bidding on your name and inflating your brand clicks (should I bid on my own brand name on Google Ads)? Would Bing’s quieter auction suit your margins (should I advertise on Bing as well as Google)? And if you are in a trade where Google’s Local Services Ads operate, their pay-per-lead model gives you a fixed cost per lead by design (what are Google Local Services Ads). Google Ads is often the right channel. It is rarely the only one.

Frequently asked questions
What is the average cost per lead on Google Ads in 2025?
WordStream’s 2025 benchmark, from over 16,000 mostly US campaigns, puts the all-industry average at $70.11. Industries range from about $28.50 for automotive repair to $131.63 for legal services. Treat it as a sense check: whether your figure is good depends on what a lead is worth to you.
What is a good cost per lead for a small business in the UK?
There is no published UK benchmark worth trusting, which is why the maths matters more than the average. Work out what a lead is worth from your own job values and close rate, then hold your cost per lead well inside that. Most healthy small-business accounts we see land between £20 and £80 per genuine enquiry, but your numbers outrank any rule of thumb.
How do I work out what I can afford to pay per lead?
Multiply your average job value by the share of leads you close. A £1,000 average job with a one-in-four close rate makes a lead worth £250 before costs. Your cost per lead needs to sit well inside that, leaving room for your margin and the time spent quoting the leads you do not win.
Why did my cost per lead suddenly go up?
Check three things in order: whether tracking changed and is counting differently, whether new broad keywords are matching irrelevant searches, and whether competition pushed click prices up. Google Ads costs have risen for five consecutive years, so some upward drift is normal, but a sudden jump usually has a findable cause in the account.
Does a bigger budget lower my cost per lead?
Usually the opposite past a point. A bigger budget forces Google to spend it somewhere, which often means broader keywords and weaker searches. Cost per lead falls when targeting, tracking and the landing page improve, and budget simply feeds a machine that already works. Raise the budget after the cost per lead is healthy, not to fix it.
Is a low cost per lead always good?
No. A £10 lead that never answers the phone is more expensive than a £60 lead who books. Judge cost per lead alongside lead quality: how many turn into quotes, and how many quotes turn into paid work. That is why call tracking and honest lead records matter as much as the ad account.
Should I use Google’s Target CPA bidding to control my cost per lead?
Only once your tracking is trustworthy. Target CPA tells Google to chase a cost per conversion you set, but it optimises for whatever you count as a conversion. Point it at junk actions and it will find you cheaper junk faster. With clean call and form tracking and a few months of real data, it can be a sensible tool. Treat automated bidding as an optimization tool, not a strategy: it tunes towards the number you give it, so give it a number built on real leads.
