Across 13,474 US search campaigns, the average cost of one lead from a search ad is $66.69, according to LocaliQ and WordStream’s 2026 Search Advertising Benchmarks, published in May 2026. Sell legal services and it is $131.63, the highest of any category they measured. Run a restaurant and it is $30.57.
Those are the prices. Whether they are worth paying is a separate question, and you can answer it at your kitchen table in ten minutes with a pen.
What a click and a lead cost in 2026
Three numbers drive the rest. In that same LocaliQ and WordStream data, based on US Google Ads and Microsoft Ads search campaigns from April 2025 through March 2026, the average cost per click is $5.42, the average click-through rate is 6.64%, and the average conversion rate is 8.18%.
They chain together. Buy 100 clicks at $5.42 and you have spent $542. If 8.18% of those visitors call or fill out the form, you got about eight leads, near $66 apiece.
Two caveats before you build a budget on this. WordStream and LocaliQ are the same company. WordStream brands itself as WordStream by LocaliQ and both carry the same USA TODAY Co copyright, so most of the benchmark data in this post comes from one advertising platform measuring its own managed accounts. Second, those 13,474 campaigns all ran through that platform, which means they describe businesses already paying somebody to mind the account and leave out the worst-run accounts in the country. Treat them as a center of gravity, not a promise.
The first cost-per-lead drop in five years
Costs moved in two directions at once this year. Cost per click rose to $5.42 from $5.26, while cost per lead fell to $66.69 from $70.11, which LocaliQ and WordStream note is the first cross-industry decrease in five years. Clicks got more expensive while leads got cheaper, so conversion rates improved enough to absorb the increase.
What your industry costs
The all-industry average is close to useless for planning. Here is what LocaliQ and WordStream recorded for a handful of categories in that same 2026 study:
| Category | Cost per click | Cost per lead |
|---|---|---|
| Attorneys and legal services | $9.87 | $131.63 |
| Home and home improvement | $8.33 | $90.92 |
| Dentists | $8.00 | $72.97 |
| Personal services | $7.17 | $54.60 |
| Restaurants and food | $2.05 | $30.57 |
An attorney pays more than four times what a restaurant pays because a case is worth more than a dinner.
A measurement trap sits under these numbers. Ruler Analytics’ Conversion Rate Benchmarks 2026, published in May 2026 and based on more than 110 million sessions across 13 industries, found that 56.3% of legal conversions and 52.6% of professional services conversions arrive as phone calls rather than forms. Count only form fills and you are seeing half your leads, with a cost per lead that looks twice as bad as the truth.
The break-even math, worked out
Do this before you spend anything. What follows is illustrative. The business does not exist.
Take a home improvement contractor. Four inputs, only the first from a study:
- Benchmark cost per lead: $90.92, from LocaliQ and WordStream
- Close rate: 25%, one in four leads becoming a paying job. You supply this.
- Average job value: $3,200. You supply this.
- Gross margin: 40%, what is left after materials and labor. You supply this.
Cost per sale is cost per lead divided by close rate. $90.92 divided by 0.25 is $363.68, which is the four leads you buy to land one job.
Gross profit per job is job value times margin. $3,200 times 0.40 is $1,280.
Subtract, and $1,280 minus $363.68 leaves $916.32 on the job after the advertising is paid for. On those inputs, ads work.
The more useful number is the edge. Divide the cost of one lead by the gross profit on one job: $90.92 divided by $1,280 is 0.071, or 7.1%. That is your break-even close rate. Close one in fourteen leads and the advertising pays for itself. Better is profit. Worse is a subsidy you are paying Google.
In plain words, so you can run it on your own numbers:
Cost per lead divided by your close rate is what one customer costs you. Average sale times gross margin is what one customer is worth. If the second is bigger, ads can work. Cost per lead divided by gross profit per sale is your break-even close rate.
Run it again at a close rate you would be embarrassed by. At 10%, our illustrative contractor pays $909.20 per job against $1,280 of gross profit, still positive but thin enough that a slow month erases it.
Where a third of the money goes
The same WordStream account study, based on 251,236 Google Ads Grader reports run by 15,666 accounts between January and November 2025, found the average business wastes $1,127.54 a month in Google Ads, or $3,383 over 90 days. Against average monthly spend of $3,127.38, roughly a third of the budget buys nothing.
Put that back into the contractor math. At $90.92 per lead, $1,127.54 is twelve leads a month, spent instead on searches from people who were never going to hire anybody. Further down the distribution, that study found 29% of accounts recorded zero conversions over a 90-day period while still averaging 12,667 impressions a month, and 36% have a Quality Score below 4. Those accounts were live and somebody was paying the invoice.
So the honest planning number is the benchmark plus a margin for waste, unless someone is minding the account week to week.
The negative keyword problem
A negative keyword tells Google which searches to keep you out of. A plumber wants to block “plumber salary,” “plumber school,” and “plumber jobs.” Those clicks cost the same as a real customer and none will ever hire you.
In that WordStream account study, 25% of businesses had never added a single negative keyword. Accounts with at least one averaged a 13% monthly conversion rate. Accounts with none averaged 4.6%.
That gap is wider than negative keywords alone can explain, so do not read it as cause and effect. An account with negatives in it is an account somebody is watching. Either way, a quarter of advertisers have never done the cheapest maintenance available.
When not to run ads at all
Start with whether advertising is your problem at all. The NFIB Research Center’s Small Business Problems and Priorities, 11th edition, published in July 2024, mailed 40,000 surveys and got 2,873 usable responses, asking owners to rate 75 problems on a scale from 1, critical, to 7, not a problem. “Ability to cost-effectively advertise” landed 46th of the 75. Only 6.8% of owners called it a critical problem. That is a trade association asking its own members rather than an ad platform asking its customers, and it says plainly that most small business owners are kept awake by something else.
LocaliQ’s Big Small Business Marketing Trends Report for 2026, a survey of more than 300 small business owners published in October 2025, found that 52% have monthly marketing budgets under $1,000 and half have nobody on staff dedicated to marketing. WordStream found 24% of ad accounts spend under $1,000 a month.
Set that beside the waste figure. The average account throws away $1,127.54 a month, more than many small businesses have to spend on everything. If your budget is $800, the average of $66.69 buys twelve leads a month, and at attorney rates it buys six. That is not enough to learn from, and not enough volume for Google’s bidding to optimize against.
A few other situations where we would tell you to wait. When one sale cannot carry the cost of a lead, ads only work on repeat business. A restaurant paying $30.57 per lead does not recover it on one dinner.
When nobody answers the phone, do not start. With 56.3% of legal conversions arriving as calls in the Ruler Analytics data, voicemail is where a lead you already paid for goes to die.
And when the site does not convert, fix the site first. The 8.18% average conversion rate in the LocaliQ and WordStream benchmarks turns $5.42 clicks into $66 leads. At 2%, the same clicks produce a $271 lead, and no bidding strategy rescues that.
Run the number first
Ads are a lever, not a strategy. They pull harder on something already working and pull nothing out of something that is not. The calculation comes before the campaign, and it costs nothing to run.
Done right, none of this is dramatic. Someone reads the search terms report and adds negatives before the money is spent. Someone knows your close rate and average job value well enough to say whether last month paid for itself, and says so plainly when it did not. That is most of what our PPC work is, and why we ask for those numbers before we talk about budget.
So here is the next step, and you can take all of it without talking to anybody. Write down three numbers: your close rate on the leads you already get, your average sale, and your gross margin. Find your industry in the table above and run the arithmetic from the break-even section. If it comes out negative, you just saved yourself a year of ad spend. If it comes out positive, open the search terms report in whatever account you already have and read the last 30 days of it. Whatever you find there is the honest opening bid on how much attention this needs.
