Most articles about criminal defense Google Ads costs stop at cost per click. That number tells you almost nothing. A $40 click that turns into a $12,000 felony retainer is cheap. A $9 click from someone whose case is in another state is expensive. The number that matters to a defense firm is what you spend to sign a client, and what that client pays you.
This article uses real numbers from eleven months of Google Ads and Local Services Ads for Amari Law Firm, a two-attorney, flat-fee criminal defense practice in Birmingham, Alabama. Revenue is the signed fee from the firm’s case management system, not Google’s conversion count.
The short answer
| Metric | Google Ads | Local Services Ads |
|---|---|---|
| Period | Sep 2025 – Aug 2026 | Jan – Aug 2026 |
| Ad spend | $146,851 | $61,094 |
| Signed-case fees | $496,700 | $336,950 |
| Signed cases | 140 | — |
| Ad spend per signed case | $1,049 | — |
| Return on ad spend | 3.4× | 5.5× |
The average signed case brought in about $3,500 in fees. So the firm spent roughly $1 for every $3.40 it signed through Google Ads, and $1 for every $5.50 through Local Services Ads. Those are good numbers for criminal defense, but the averages hide the part that actually decides whether a month is profitable.
Why cost per click is the wrong place to start
Criminal defense clicks are among the most expensive in legal advertising, and they vary a lot by city, charge and time of day. Firms compare click prices because it’s the number Google shows first. But two firms paying the same price per click can have completely different results, because:
- Not every call is a case you can take. Out-of-state charges, people looking for a different firm by name, and matters you don’t handle all cost the same as a real lead.
- Not every case is worth the same. A misdemeanor flat fee and a felony retainer can differ by $10,000 or more.
- Intake decides what a lead is worth. A caller who isn’t reached quickly after an arrest usually calls the next firm.
That’s why the numbers below are built around signed cases and fees, not clicks or calls.
What criminal defense keywords cost per click in 2026
Here is what Google itself reports. These are top-of-page bid ranges from Google Ads Keyword Planner for the United States, covering October 2025 to September 2026. The low number is roughly what the cheaper advertisers paid to appear above the organic results; the high number is what the most aggressive advertisers paid. Your city can sit well above or below these ranges.
| Search | Monthly searches (US) | Top-of-page bid, low | Top-of-page bid, high |
|---|---|---|---|
| dui lawyer | 100K – 1M | $15.63 | $131.88 |
| dwi lawyer | 100K – 1M | $15.63 | $131.88 |
| dui attorney | 10K – 100K | $14.24 | $127.30 |
| dui lawyer near me | 10K – 100K | $8.12 | $102.19 |
| criminal defense lawyer | 100K – 1M | $7.35 | $86.00 |
| federal criminal defense attorney | 1K – 10K | $8.01 | $85.00 |
| assault lawyer | 1K – 10K | $8.52 | $82.88 |
| criminal defense attorney | 10K – 100K | $6.47 | $77.63 |
| domestic violence lawyer | 1K – 10K | $6.83 | $69.35 |
| criminal lawyer | 10K – 100K | $6.97 | $66.92 |
| criminal lawyer near me | 10K – 100K | $4.45 | $66.15 |
| drug possession lawyer | 1K – 10K | $5.59 | $53.56 |
| theft lawyer | 1K – 10K | $4.88 | $34.08 |
| expungement lawyer | 10K – 100K | $3.08 | $27.50 |
Three patterns stand out. DUI and DWI searches are the most expensive in criminal defense, often twice the price of a general “criminal defense attorney” search, because the case is common, the fee is predictable and every firm bids on it. Charge-specific searches like assault and federal defense cost about as much as the general terms but tell you far more about the caller. And lower-fee matters like expungement are cheap to click for a reason: the case is worth less. For DUI specifically, see Google Ads for DUI lawyers.
That is why the price of a click on its own decides very little. A $120 DUI click is fine if one in eight of those callers signs a $4,000 fee. A $30 expungement click is expensive if the case pays $750 and the caller wanted free information.
What drove cost per case up or down
1. A few big cases decide the month
The strongest month brought in $89,500, and 53% of it came from three matters worth $10,000 or more. Weak months signed about as many cases, but at $2,000 to $3,000 each. Months with at least one case over $10,000 averaged a 5.3× return; the other seven months averaged 3.0×.
The lesson for budgeting is that cost per case alone can mislead you. A month with a higher cost per case can still be the best month of the year if it signed one serious felony.
2. More budget did not mean more revenue
| Monthly ad spend | Signed fees | Return |
|---|---|---|
| $4,979 | $37,500 | 7.5× |
| $24,085 | $53,250 | 2.2× |
Spend went up almost fivefold. Signed fees went up 42%. The extra budget went to broader searches and less likely callers. In criminal defense, the first dollars buy the most urgent, local, high-intent searches. Later dollars buy everything else.
3. Broad keywords returned half as much
Broad searches like “criminal attorney” produced plenty of conversions but returned about 2×, against about 4× for charge-specific, high-intent searches. Moving budget from the first group to the second was one of the biggest improvements in the account.
4. One campaign had never signed a case
The DUI campaign generated conversions every month, so it looked healthy in Google Ads. When calls were matched to signed matters, it had zero signed cases in its history. It was rebuilt around the DUI searches that actually produced clients. Without signed-case tracking, that campaign would still be running.
5. Waste you can see in the search terms
- Searches for other firms by name: fixed with more than 100 competitor names as negative keywords.
- Callers whose charges were in another state: fixed with tighter location targeting and ZIP code exclusions.
- A paused brand campaign that had spent $2,714 with little to show for it since March.
- Domestic violence searches landing on the expungement page: fixed by sending each charge to its own page.
Merging four overlapping campaigns and moving to exact match cut weekly spend 38% and cost per conversion 65% in the first week.
How much do lawyers pay for leads in criminal defense?
“Cost per lead” means different things depending on where the lead comes from, which is why the numbers you see quoted online vary so much.
- Google Ads charges per click. Your cost per lead is your spend divided by the calls and forms you got, so it depends on your website and how many clicks turn into calls.
- Local Services Ads charge per lead: you pay when someone calls or messages you through the ad, and you can dispute leads that were not real prospects.
- Lead sellers and directories charge per lead or a flat monthly fee, and the same lead is often sold to more than one firm.
For a defense firm, cost per lead is only the middle of the calculation. What matters is how many of those leads sign and what they pay. In the Amari Law Firm account, every figure in this article is measured at the signed case, because a cheap lead that never retains is the most expensive lead you can buy.
Is Google Ads worth it for criminal defense lawyers?
It is worth it when the fee you sign is comfortably larger than what it costs to sign the case. You can work out your own break-even before spending a dollar:
- Take your average signed fee. In the Birmingham account it was about $3,500.
- Decide what share of that fee you can spend to win the case. Many firms are comfortable spending a quarter to a third of the fee.
- That gives you a maximum cost per signed case. At $3,500 and one third, it is about $1,150.
- Compare it with what you actually pay. The Amari account spent $1,049 per signed case on Google Ads, which is why it was profitable at a 3.4× return.
Google Ads usually is not worth it yet if any of these are true:
- Nobody answers the phone nights and weekends, when many arrests happen.
- You cannot tell which signed clients came from ads, so you can never tell good keywords from bad ones.
- Your budget is too small to buy enough clicks for the account to learn (see below).
- Your average fee is low and your market is crowded, so the math above does not close.
Is $20 a day, or $500 a month, enough for criminal defense Google Ads?
Usually not for search ads. At the top-of-page bids above, $20 a day ($600 a month) buys somewhere around five to fifteen clicks a month on general criminal defense searches, and fewer on DUI. That is not enough traffic to sign cases reliably, and nowhere near enough for Google’s automated bidding to learn which callers are worth paying for.
With a small budget you have better options:
- Start with Local Services Ads, where you pay per lead instead of per click.
- Run search ads only for your highest-value charge in your home county, at the hours your office can answer.
- Fix your call tracking first, so the money you do spend teaches you something.
| Monthly Google Ads budget | What it can realistically do for a defense firm |
|---|---|
| Under $2,000 | Too little for broad search. Use Local Services Ads and a tightly limited search campaign for one charge. |
| $2,000 – $5,000 | Enough for one or two charge-specific campaigns in one county. Bidding should stay simple. |
| $5,000 – $15,000 | The range where, in my experience, most single-office defense firms find their efficient spend. |
| $15,000+ | Growth depends on bidding for case value and on separate campaigns by charge and area. |
How much should a criminal defense firm spend on Google Ads?
There’s no universal number, but there is a useful way to think about it. Start with the minimum that lets the account learn, then grow only while signed fees grow with it.
- Below about $5,000 a month, most defense firms can’t buy enough clicks for Google’s bidding to learn which callers sign. Local Services Ads is often the better first step at small budgets.
- $5,000 to $15,000 a month is where, in my experience, most single-office defense firms find their efficient spend: urgent, local, charge-specific searches.
- Above $15,000 a month, growth depends on bidding for case value, because the cheap, obvious searches are already covered.
Watch for the point where more spend stops adding signed fees. In the Birmingham account, that point arrived well before the budget did. Raising the Jefferson County budget made sense because the firm was losing 47.5% of possible impressions to budget; after the increase, impression share went from 44.5% to 86.2%. Raising budget in areas that didn’t sign cases would not have.
What Local Services Ads cost compared with search ads
Local Services Ads charge per lead instead of per click, and they appear above regular search ads with a Google Screened badge. In this account they were the most efficient paid channel: $336,950 in signed fees on $61,094 over eight months.
Two things kept the cost per case down. A monthly review disputed invalid leads, recovering roughly $850 to $1,300 a month in credits, about 15% of charged leads in June. And low-value categories like minor traffic tickets were turned off, so the budget went to higher-fee matters. Read more in Local Services Ads for criminal defense lawyers.
How to calculate your own cost per signed case
- Pick a period that has matured. Cases often sign one to three months after the first call, so last month will always look worse than it ends up.
- Add up ad spend for that period, net of any invalid-click refunds.
- Count signed matters that came from ads, using call tracking to match each new client to the call or form that brought them in.
- Add up their fees, using what was actually signed, not quoted. In this account, quoted-but-unpaid matters turned into only about a quarter to a third of their quoted value.
- Divide spend by signed cases, then fees by spend. Those two numbers are your cost per case and your return.
If you can’t do step 3, that’s the first thing to fix. Here’s how to connect calls to signed cases in Clio and send them back to Google Ads.
What a healthy criminal defense account looks like
- You know your cost per signed case by campaign and by charge, not just by month.
- Keywords are judged on fees per lead, so a $90 click that signs felonies beats a $15 click that never signs.
- Calls are answered fast, nights and weekends included, because that’s when arrests happen.
- Budget increases follow signed fees, judged on months that have had time to mature.
How much does Google Ads cost for criminal defense lawyers?
Clicks on criminal defense searches typically cost from about $5 to over $130 at the top of the page, according to Google’s Keyword Planner, with DUI and DWI searches the most expensive. What matters more is cost per signed case: in one Birmingham firm’s account it was $1,049, with an average fee of about $3,500.
How much do criminal defense lawyers spend on Google Ads per month?
In my experience, single-office criminal defense firms that advertise seriously spend somewhere between $5,000 and $15,000 a month. Over eleven months, one Birmingham firm spent $146,851 and signed $496,700 in fees across 140 cases.
What is a good cost per signed case for criminal defense?
It depends on your average fee. A useful ceiling is a quarter to a third of the fee. In the Amari Law Firm account, Google Ads cost about $1,049 per signed case against an average fee of about $3,500, a 3.4× return.
How much do lawyers pay for leads?
It depends on the source. Google Ads charges per click, so cost per lead depends on how many clicks call you. Local Services Ads charge per lead and let you dispute invalid ones. Lead sellers charge per lead and often sell the same lead to several firms. For criminal defense, judge every source on cost per signed case, not cost per lead.
Is Google Ads worth it for lawyers?
Yes, when your cost per signed case is comfortably below your average fee and you can answer calls quickly, including nights and weekends. It is usually not worth it if you cannot track which clients came from ads or your budget is too small for the account to learn.
Is $20 a day enough for Google Ads for a law firm?
Rarely, for criminal defense search ads. At typical top-of-page bids, $20 a day buys only a handful of clicks a month. Local Services Ads, or one tightly targeted campaign for your highest-value charge, are better uses of a small budget.
Why are DUI clicks more expensive than other criminal defense searches?
DUI cases are common, the fees are predictable and nearly every defense firm bids on them, so the auction is crowded. Keyword Planner shows top-of-page bids for “dui lawyer” up to about $132, against about $86 for “criminal defense lawyer.”
Are Local Services Ads cheaper than Google Ads for criminal defense?
They were more efficient in the Amari Law Firm account: a 5.5× return compared with 3.4× for search ads. LSA charges per lead, and disputing invalid leads recovered about 15% of charged leads in one month.
How long before I know if Google Ads is profitable?
About 90 days. Cases often sign one to three months after the first call, so judge results on months that have had time to mature.
