Criminal lawyer advertising is the paid side of criminal defense marketing: the search ads, feed ads and listings a firm buys to be the one that gets the call after an arrest.
It runs under two constraints injury advertising does not have: fees come up front, not out of a recovery, and the rules around records and open cases are tighter.
Is it illegal for lawyers to advertise?
The starting point is the Supreme Court: in Florida Bar v. Went For It (1995), the Court described Bates v. State Bar of Arizona (1977) and later cases as treating lawyer advertising as commercial speech, which carries limited First Amendment protection.
So the answer is no: advertising is regulated, not banned, and the regulation comes from the states.
ABA Model Rule 7.2(a) lets a lawyer communicate about their services through any media, and the version your state adopts supplies the content rules and filing requirements that bind the firm.
The general rulebook behind all of it is covered rule by rule in lawyer advertising rules.
Which criminal defense lawyer advertising channels work
The demand side shapes the answer: a defense client often has days rather than weeks, and the searcher is just as often a spouse or parent calling for someone else.
Channels at the moment of search win that call more often than channels that interrupt, the split law firm advertising draws between demand capture and demand generation.
Local search and the map pack
Where arrest-driven searches land, earned with profile work, reviews and practice-area pages.
Google search ads
Bids on the search the moment it happens, with narrower targeting tools than other industries get.
Meta ads
Facebook and Instagram placements that reach people who were not searching; copy rules below.
Local Services Ads
Google's pay-per-lead product for verified firms; explained here, not managed by More Booked Cases.
Google's policies touch criminal defense twice, both as of October 2026: the Commission of a crime sensitive-interest category names criminal defense lawyers as an example, which limits audience-targeting tools, not the ads themselves, and a separate policy does not allow promoting bail bond services.

DUI is the largest single demand pocket inside the practice, with its own plan in DUI lawyer marketing.
What the fee rule does to the ad budget
ABA Model Rule 1.5(d)(2) bars a contingent fee for representing a defendant in a criminal case, and your state's version of the rule controls.
Defense fees are therefore flat or hourly, with the retainer collected up front or on a plan, and no verified source publishes typical flat-fee amounts.
The model rule bars them in domestic-relations matters where payment depends on the divorce outcome, which shapes divorce lawyer advertising the same way.
That rewrites the ad math: instead of a contingency recovery repaying months of mass reach, every signed case is worth a knowable fee, so a channel only pays if cost per signed case stays small.

A channel priced for injury economics can be unsalvageable in defense, and the way to tell is in cost per signed case.
What the numbers say about criminal defense leads
In MyCase's 2024 Benchmark Report, built on 2023 data from its own customers, consultations logged equaled 8% of leads logged in criminal law, 11,337 consultations against 138,379 leads, compared with 14% across all practice areas.
The ratio counts records entered in one company's software, many firms never log consultations, and MyCase itself says consultations are more common where clients shop around, so it is a reason to measure your own funnel, not a target.
Converted criminal law leads went from lead intake to conversion in an average of 5 days in the same report, against 3 days in personal injury and 16 in immigration and employment, averages for converted leads in one software base.
Five days is longer than a fresh arrest wants to wait, which is why answered phones and fast follow-up do as much for a defense firm as the ads; the metric is in consultation to signed case rate.
What criminal defense attorney advertising can say
Two rulebooks govern the copy: your state's adopted advertising rules and the ad platforms' own policies.
ABA Model Rule 3.6(a) bars a lawyer in a matter from making public statements the lawyer knows or should know have a substantial likelihood of materially prejudicing the proceeding, and Rule 3.6(d) reaches the firm's other lawyers.
Rule 3.6(b) permits a specific list: the claim or defense, public-record information, the scheduling or results of litigation steps and, in criminal cases, the fact, time and place of an arrest.
Anything outside the public record stays confidential under Rule 1.6, and the press-facing version of the rule is in law firm PR.
On the platform side, Meta's personal-attributes policy bars ads that assert or imply the viewer has a criminal record, and Meta's own not-allowed example asks the reader "Are you a convicted felon?" (policy last updated June 26, 2024).
Meta's policy describes the acceptable pattern as describing the service, not the viewer, and applies it case by case, so no headline is pre-approved.
Describes the service
- Practice areas, availability, an arrest line answered around the clock, a consultation, a fee quoted up front: copy about the firm, addressed to no one's record.
- Meta's own example of the pattern states that a service is available rather than asking about the reader.
Implies a personal attribute
- "Are you a convicted felon?" is Meta's not-allowed example, because it asserts the viewer's criminal record.
- Without Meta's prior written permission, lead forms may not ask whether a person was charged with or convicted of a crime, has declared bankruptcy, or about health or insurance details (as of October 2026).
The practical read: the screening questions, charged or convicted, which court, when is arraignment, belong on your own intake form after the click, an inference from the policy rather than a ruling; the form detail is in Meta lead forms for law firms.
Judge the ads by cost per signed case
No published benchmark gives a criminal defense firm a target cost per lead or per signed case, so the numbers that matter are the firm's own.
A worked example, illustrative throughout: $3,000 in Meta fees plus $3,000 in spend produces 40 inquiries, 10 consultations and 4 signed cases at a $2,500 flat fee, which is $1,500 per signed case against $10,000 in signed fees.
If the same spend signs 6 instead of 4 because the landing page holds more of the funnel, cost per signed case drops to $1,000, which is why conversion work and advertising get judged together here.
The rules here are model rules and platform policies as of October 2026, your state's adopted versions control, and the last step before a campaign runs is a read-through with your state bar's ethics counsel or an ethics lawyer.
Frequently asked questions
Is it illegal for lawyers to advertise?
No. The Supreme Court described lawyer advertising as commercial speech in Florida Bar v. Went For It (1995), citing Bates v. State Bar of Arizona (1977) and later cases, which means it carries First Amendment protection, though a limited one. States still regulate what an ad may say, so your state's adopted rules control.
Can a criminal defense ad mention a criminal record?
Not as a statement about the viewer. Meta's personal-attributes policy bars ads that assert or imply the reader has a criminal record, and Meta's own not-allowed example asks the reader whether they are a convicted felon. Meta's example of an acceptable pattern describes the service instead, and Meta applies the policy case by case.
Can a Facebook lead form ask if someone was arrested?
Not without Meta's prior written permission: Meta's lead ad rules say forms may not ask whether a person has been charged with or convicted of a crime. The practical read is that those questions belong on the firm's own intake form after the click, which is an inference from the policy, not a ruling.
How much do criminal defense lawyers charge per hour?
Clio's 2025 Legal Trends Report records a $217 average hourly rate for criminal matters among Clio users, against $335 for personal injury and $343 for family. These are rates recorded in one software base, including on flat-fee and contingency matters, not a price list.
How fast do criminal defense leads decide?
In MyCase's 2024 Benchmark Report, converted criminal law leads went from lead intake to conversion in an average of 5 days, against 3 days in personal injury and 16 in immigration and employment. Those are averages for converted leads in one software base, not a deadline.
