TL;DR: Legal keywords average $9.87 per click, nearly double the $5.42 all-industry average (LocalIQ, June 2026). DUI defense is not a restricted Google Ads category, but bail bond bans, criminal-offense audience limits, and Local Services Ads screening all constrain the build. Here is the campaign structure that survives them.
What “restricted category” actually means for DUI advertising
Start with the honest version. DUI defense is not on Google’s restricted business list. There is no certification to apply for and no verification queue to wait in.
Ads still get disapproved, limited, and throttled. The pressure comes from three policies that sit next to criminal defense rather than on top of it.
Bail bond services are banned outright
Google’s Other restricted businesses policy is blunt about it. “Promotion of bail bonds services that offer to act as surety in order to secure bail for a defendant is not allowed,” per Google’s Advertising Policies Help documentation (accessed September 2026). The prohibited list names commercial bail bond agents, bail bondsmen, bail bonds financing services, bounty hunters, immigration bail services, and detention bail services.
That matters if your firm cross-sells bail help. A single “how to post bail” page on the advertised domain can pull a review. Move bail content to a separate domain, or keep it off every page your ads touch.
You cannot build audiences around criminal offenses
Google’s personalized advertising policy lists “Commission of a crime” as a restricted sensitive interest category. Advertiser-curated audiences cannot be built on it. Predefined Google audiences stay available.
This kills the obvious retargeting plan. You cannot upload a Customer Match list of former DUI clients and call it an audience. You cannot build a remarketing segment out of everyone who read your arrest guide and treat it as criminal-offense intent.
Firms that ignore this get audience rejections at the account level, not a polite warning.
Local Services Ads add a license and background gate
LSAs sit above the text ads on legal queries, and they run on a different rulebook. Google requires background checks, license checks, business registration, and insurance verification before the Google Screened badge appears, per Local Services Help documentation for the United States. For a DUI practice that means an active bar license in good standing, verified before a single lead arrives.
Verification is not instant. Start it before you plan the launch date. Our Local Service Ads for Law Firms: The 2026 Management Guide covers the submission sequence and the lead dispute process.
One more policy lands in October 2026
Google is tightening its Government documents and services policy, with enforcement beginning October 5, 2026. Only certified governments and authorized providers may run ads promoting direct acquisition of specific government documents and services. To qualify as an authorized provider, your domain has to be linked from an official government website and named there as authorized.
DUI firms advertising license reinstatement or DMV record retrieval as a standalone service should read that policy now. A “get your license back” offer written like a records service reads very differently to a policy reviewer than a legal representation offer does.
The cost math you are actually signing up for
Legal is the most expensive category in paid search, and it is not close.
LocalIQ’s 2026 Search Advertising Benchmarks report, published June 1, 2026, puts the Attorneys and Legal Services average cost per click at $9.87. The all-industry average is $5.42. Average cost per lead in legal is $131.63 against $66.69 across all industries. Legal conversion rate lands at 5.55%.
Why so high? Every DUI query has a small set of firms bidding on it, in the same county, each chasing a case worth thousands of dollars. That auction pressure is local and permanent. You cannot out-wait it. You can only out-structure it.
Our own managed accounts run tighter. Across iClick-managed accounts in 2024 and 2025, personal injury search sits at $6.75 CPC with a 6.98% conversion rate, and our portfolio-wide Google Search average is $2.32 CPC. Those are well-optimised accounts, not market medians.
Public benchmark reports group DUI defense inside one broad Attorneys and Legal Services bucket. No major benchmark report breaks out DUI as its own category, but LocaliQ’s Legal Search Advertising Benchmarks report puts the average cost per click for the Criminal Law category (the bucket DUI campaigns fall into) at $12.30, the highest of any legal practice area it measured and well above the $9.21 legal-wide average (data covering April 2022 through March 2023).
Run the arithmetic before you commit. At $9.87 per click and a 5.55% conversion rate, one lead takes about 18 clicks, or roughly $178. If four leads produce one signed case, your cost per signed case is near $712 before intake staffing. That is the number that decides whether the channel works for you. Our breakdown of how much a personal injury firm should spend on Google Ads applies the same model to a larger practice area.
Targeting when the audience layer is off limits
Put the intent in the query, not the audience
With criminal-offense audiences unavailable, keyword control carries the campaign. Build tight exact and phrase match groups around hiring language: dui lawyer near me, dui attorney plus city name, arrested for dui, dmv hearing attorney, first offense dui lawyer.
Then spend real time on negatives. Block free, pro bono, public defender, salary, how to become, law school, checkpoint, penalties for, and jail time for. Research queries drain a DUI budget faster than your competitors do.
Segment by charge, not by geography alone
A first offense misdemeanor, a felony DUI, a commercial license DUI, and a refusal case are four different buyers with four different fee ranges. One campaign averaging them together hides which one actually pays.
Split them. Give each its own ad group, its own landing page, and its own conversion value. Radius targeting around the courthouses you appear in beats state-level targeting every time.
Keep Performance Max on a short leash
Performance Max will spend a DUI budget on cheap, unqualified volume if you let it. It has broad inventory and thin keyword-level visibility, which is the opposite of what a policy-adjacent vertical needs.
If you run it at all, run it after Search is profitable, with brand excluded, a tight geo, and signed-case values feeding the bidding. Check the placement and search themes reports weekly. Pull the plug fast when lead quality drops.
Ad copy and landing pages that clear review
Write to the charge, not to the practice
Google’s misrepresentation rules and your state bar’s advertising rules point the same direction: no promised outcomes. “Charges dropped, guaranteed” is a disapproval and a bar complaint in one line.
Write what you can prove instead. Years in practice. Number of DUI trials. Same-day consultations. Bar admissions. Named court experience.
On the landing page, keep four things above the fold: the charge you handle, the county you handle it in, a tap-to-call number, and a form under five fields. Someone searching at 3 a.m. after a booking is not reading your firm history. Add the disclaimers your jurisdiction requires. A compliant page that runs beats an aggressive page that gets the account suspended.
Track the call, not the click
Most DUI conversions are phone calls, and plenty of those calls are junk. Set a minimum call duration before a call counts as a conversion, usually 60 seconds or more, so hang-ups and wrong numbers stop training your bidding.
Use Google forwarding numbers on ads and a call tracking platform such as CallRail or CallTrackingMetrics on the site. Record calls where your state allows it. Then listen to 10 of them a month. No keyword report will tell you that your best converting query brings in people who cannot pay a retainer.
Intake decides whether the spend was worth it
The 2024 Clio Legal Trends Report ran a secret shopper study on law firms. Only 40% of firms answered the phone, down from 56% in 2019. Just 33% responded to email, down from 40% in 2019. And 48% were essentially unreachable by phone.
Put that against a $131.63 cost per lead. Roughly half the market is buying expensive clicks and dropping the calls those clicks generate.
DUI intake is harder than most practice areas. The call comes overnight, from a jail phone or a panicked family member, and it does not wait for business hours. Answer live, 24/7, or route to a service that does.
The lift is measurable. At McEldrew Purtell, a catastrophic injury firm, iClick drove a 697% increase in conversions and a 53% reduction in cost per acquisition inside 90 days, with call volume doubling. Kevin Wittner, their Head of Marketing, described cost per lead coming “down by over 40%” while call volume climbed.
Measure cost per signed case, not cost per lead
Cost per lead flatters bad accounts. A DUI campaign can cut CPL by 30% and sign fewer cases, because the cheap leads are people shopping for free advice.
Feed signed cases back into the account instead. That means offline conversion imports from your case management system, values assigned by charge type, and Smart Bidding optimising against fee revenue rather than form fills.
At Georgia Probate Law Group, that shift produced a 40% reduction in cost per signed case and an 85% increase in qualified intakes across two states. Across our portfolio, the average conversion goal lift is 41%.
The weekly numbers that matter
- Cost per signed case, broken out by charge type
- Qualified intake rate, meaning intakes that met your fee minimum
- Answer rate on ad-driven calls, with after-hours measured separately
- Search term waste, the share of spend on queries you would never bid on manually
- Impression share lost to budget in your top two counties
Our deeper piece on cost per signed case, the only law firm PPC metric that matters covers the tracking setup, including how to value a case before it closes.
What to look for in a DUI lawyer Google Ads agency
Most agencies pitching criminal defense have never had an account suspended, because they have never run anything policy-adjacent. That is not a qualification.
Five questions worth asking
- Which restricted or policy-sensitive categories have you run, and did the accounts stay alive?
- Do you report cost per signed case or cost per lead?
- Who owns Local Services Ads verification and lead disputes?
- How do you structure campaigns when criminal-offense audiences are unavailable?
- What happens to my budget in the first 30 days?
iClick has managed more than $61M in ad spend since 2017 across 250+ clients, and has held Google Premier Partner status (top 3% of partners) for more than five years. Restricted-category work is a real part of that. On Lynk Pleasure, a restricted-category eCommerce account, we hold 4.7x ROAS with zero account suspensions. The policy discipline transfers.
Our legal work spans law firm PPC management, including criminal defense, personal injury, family law, and probate. The full framework sits in our Law Firm PPC Playbook.
Two practical notes. We work with firms spending $20K or more per month on media. And we open with a 47-point written audit, delivered as a PDF in five business days, with no sales call attached.

Frequently asked questions
Is DUI defense a restricted category in Google Ads?
No. DUI defense has no certification requirement and does not appear on Google’s restricted business list. Three adjacent policies still apply: bail bond services are banned outright, “Commission of a crime” is a restricted sensitive interest category for personalized advertising, and Local Services Ads require license and background verification before the Google Screened badge appears.
Can I retarget people who visited my DUI landing page?
Not with an audience defined by criminal-offense interest. Google’s personalized advertising policy blocks advertiser-curated audiences built on “Commission of a crime.” Predefined Google audiences remain available. In practice, put your targeting into exact and phrase match keywords, tight geo radiuses around the courthouses you appear in, and charge-level ad groups instead.
How much should a DUI firm budget for Google Ads?
Work backwards from cost per signed case. At the LocalIQ 2026 legal benchmark of $9.87 CPC and a 5.55% conversion rate, one lead costs about $178. If four leads sign one case, that is roughly $712 per case before intake staffing. Multiply by your monthly case target, then add 20% for testing.
Do Local Services Ads work for DUI lawyers?
They sit above text ads and charge per lead, so they usually deserve a place in the mix. The cost is process. Google requires background checks, license checks, business registration, and insurance verification for United States providers before the Google Screened badge appears. Start verification early, and staff someone to dispute unqualified leads weekly.
Why do my DUI ads get disapproved when competitors run fine?
Check three things first. Bail bond content anywhere on the advertised domain, outcome guarantees in ad copy or on the landing page, and audience lists built on criminal-offense interest. Each triggers a different policy. Competitors running clean usually keep bail content on a separate domain and never promise a result in the ad.
