Short answer: most personal injury firms spend 10 to 20 percent of gross fee revenue on marketing, and firms building or rebuilding a caseload run 20 to 25 percent. The right number for a specific firm comes from its own economics: the fee a signed case produces after drop-offs, what it costs to sign that case, how many months the fee takes to arrive, and how much cash and case management capacity the firm has while it waits. A firm should keep buying cases only while its cost per signed case stays below the allowable amount those numbers produce.
How personal injury law firm marketing works
Personal injury marketing is the purchase of future attorney fees. A firm spends money today to sign cases that pay, if they pay, months or years later. Every decision in this guide follows from that one fact.
Every channel, from a billboard to a chiropractor relationship, feeds the same sequence. A person is injured and looks for help. They see the firm and make contact: that contact is a lead. Intake qualifies the lead and holds a consultation. A suitable person signs a contract and becomes a signed case. Months later most signed cases resolve and pay a fee; some withdraw, get referred out, or recover nothing.
Marketing budgets go wrong when firms measure the wrong step. A cheap lead that never signs is expensive. A projected settlement that never arrives is not revenue. Five terms keep the steps apart:
| Term | What it measures |
|---|---|
| Lead cost | Marketing spend divided by inquiries. It describes the channel's price, not its value. |
| Consultation cost | Marketing spend divided by consultations held. It shows how many leads were real prospects. |
| Signed case acquisition cost | Marketing spend divided by new signed cases. This is the number to manage. |
| Projected case value | The settlement a case is expected to produce, estimated while it is open. Useful for planning; not money. |
| Realized revenue | Attorney fees actually collected from resolved cases. The only number that pays for marketing. |
The economics of acquiring a personal injury case
A signed case is worth its expected fee: the average settlement, times the attorney fee, times the share of signed cases that actually pay. That figure, not the headline settlement, sets the ceiling on what the firm can pay to acquire a case.
A worked example
Take a firm with these hypothetical averages. They are illustrations, not benchmarks; the calculator at the top of the page uses your own figures.
Example: what one signed case is worth
- Average gross settlement
- $35,000
- Attorney fee (one third)
- $11,667
- Share of signed cases that pay a feeAssumption: the rest withdraw, are referred out or recover nothing
- 85%
- Expected fee per signed case
- $9,917
- Average time from signing to fee
- 10 months
The firm will not see $11,667 per signed case. It will see about $9,917 on average, and it will see it roughly ten months after signing. Firms that plan marketing around the full fee, or around the settled cases they remember, overestimate what each case is worth. Settled-case averages also suffer from survivorship: the cases that dropped out are not in them.
Lead cost, consultation cost and signed case cost
Suppose the same firm buys 100 leads at $300 each. Sixty become consultations and fifteen sign. The figure below follows the same $30,000 down the funnel.
The lead looked like it cost $300. The case the firm can actually bank cost $2,353. The 15 signed cases are expected to produce about $148,750 in fees (15 × $9,917), a projected return of roughly 5 to 1 on the $30,000. That projection becomes realized revenue only as the cases resolve over the following year or more.
Projected case value versus realized revenue
Case management systems are full of projected settlement amounts. They are estimates made while a case is open, usually before treatment ends and before an insurer responds. Treat them as a forecast with an error rate. Track a realization rate for each group of cases signed in the same month: fees actually collected divided by fees projected at signing. A firm whose cases routinely settle below projection, or settle early and low to relieve cash pressure, has less to spend on marketing than its pipeline suggests.
Why time to settlement decides the budget
Marketing is paid this month. The fee arrives after the case resolves. In the example, a firm that starts spending about $14,750 a month to add six signed cases a month sees almost nothing for five months, sees new fees exceed the monthly spend in month 8, and does not recover its cumulative outlay until about month 13. At the low point it has about $91,000 of cash invested in cases that have not paid yet. A budget that the fee math supports can still fail if the firm cannot fund that gap.
How much should a personal injury firm spend on marketing?
Short answer
Most personal injury firms spend 10 to 20 percent of gross fee revenue on marketing. Established firms with strong referral flow often sit near 10 percent, growth-stage firms at 15 to 20 percent, and firms building or rebuilding a caseload at 20 to 25 percent for a period. The largest advertising-driven firms have been documented at 19 to 35 percent. Treat these as orientation, then set the actual number with three tests: the fee math, the cash the firm can tie up, and the caseload its team can absorb.
Published benchmarks agree on the range and disagree on the average. One agency places personal injury firms at 10 to 20 percent of gross revenue with new or rebuilding firms at 20 to 25 percent.1 A legal finance firm's survey of published sources puts competitive injury firms at 10 to 20 percent and the largest advertising-driven firms at 19 to 35 percent.2 Another agency estimates the industry average at 9.3 percent.3 No bar association publishes a standard. These figures come from marketing and finance vendors and should be read that way.
| Stage | Typical share | What it usually funds |
|---|---|---|
| Maintain | 8 to 12% | Search presence, reviews, referral relationships, enough paid search to keep intake steady |
| Grow | 15 to 20% | The above plus Local Services Ads, case-type Google Ads campaigns and a content program |
| Aggressive or rebuilding | 20 to 30% | Heavier paid acquisition, new markets, brand advertising, often with outside capital or reserves |
Bands compiled from the published sources cited above. They describe common practice, not a rule.
What percentage of revenue should a law firm spend on marketing?
Short answer
It depends on the practice area. A common small-business guideline is 7 to 8 percent of revenue for companies under $5 million, consumer practices such as family and criminal law often spend 5 to 10 percent, and personal injury firms typically spend 10 to 20 percent or more, because each case is worth more and competitors bid those economics into every channel.2
The three tests every budget has to pass
- The fee test. The cost per signed case has to sit below the allowable amount the next section calculates. If it does not, more spend loses money on every case.
- The cash test. The firm has to fund spend for six to twelve months before the new cases pay. Cash on hand, less a reserve for payroll and rent, caps the sustainable budget.
- The capacity test. Every new signed case stays open for most of a year. Ten extra cases a month at a ten-month average adds about a hundred open files. If the team cannot carry them, service slips, cases slow down and more clients leave.
A percentage of revenue is a sanity check. The three tests are the decision. The calculator runs all three at once.
How to calculate your allowable cost per signed case
The allowable cost per signed case is the most a firm can pay to sign one case and still cover the work that case requires and leave the margin the firm needs. It is the single most useful number in personal injury marketing, and very few firms know theirs.
Cost per signed caseTotal marketing spend ÷ New signed cases
Expected fee per signed caseAverage gross settlement × Attorney fee % × Recovery rate
Break-even cost per signed caseExpected fee per signed case − Cost to work the case
Allowable cost per signed caseExpected fee − Cost to work the case − Target contribution to overhead and profit
Maximum sustainable monthly budgetAllowable cost per signed case × Signed cases a month the team can absorb
Marketing ROIFee revenue attributable to marketing ÷ Marketing spend
"Cost to work the case" is the direct cost of handling one file: case manager and paralegal time, intake, unreimbursed costs and software. "Target contribution" is what each case needs to leave behind for rent, attorney compensation and profit. Firms that skip it often find a channel "profitable" on paper while the firm itself is not.
Example: allowable cost per signed case
- Expected fee per signed case
- $9,917
- Cost to work the caseHypothetical direct cost per file
- −$2,500
- Break-even cost per signed case
- $7,417
- Target contribution (50% of the expected fee)
- −$4,958
- Allowable cost per signed case
- $2,459
- Cases a month the team can absorb
- 6
- Maximum sustainable monthly budget6 × $2,459
- $14,754
Two numbers matter here. At $7,417 a case the firm breaks even on the file and contributes nothing to overhead. At $2,459 it keeps its target margin. A channel that signs cases at $4,000 is not a failure for this firm, but it is not a reason to double the budget either.
What is a good cost per signed personal injury case?
Short answer
A good cost per signed personal injury case is any figure below the firm's own allowable cost, which for a typical auto case often lands between $2,000 and $4,000. Published paid-channel benchmarks run from about $1,000 for strong Local Services Ads campaigns to $5,000 or more for competitive Google Ads, and Atlanta paid search is quoted at $1,800 to $5,500 per signed case. Higher case values justify higher acquisition costs.
The ranges vary because the inputs vary: market, case type, intake quality and how each source defines a "signed case." One 49-firm analysis found auto accident leads averaging $391 and Southeast leads $382.4 A 13-firm analysis of paid search found $2,971 per signed case on Google Ads and $2,485 on Local Services Ads.8 A Georgia-focused agency quotes $95 to $280 per click on high-intent Atlanta terms.7
| Average settlement | Expected fee | Break-even | Allowable |
|---|---|---|---|
| $20,000 | $5,667 | $3,167 | $333 |
| $35,000 | $9,917 | $7,417 | $2,459 |
| $60,000 | $17,000 | $14,500 | $6,000 |
The first row is the warning. A firm whose average case settles near $20,000 cannot buy paid search cases at market prices and keep its margin. It needs referrals, reviews and search visibility that cost less per case, or a case mix with more value.
Personal injury marketing channels compared
No single channel wins personal injury marketing. Referrals and reviews are cheapest per case but slow to scale. Paid search is fast and scalable but expensive. SEO is slow to start and cheapest over time. Most firms that grow predictably run three or more channels and judge each one by cost per signed case.
| Channel | How you pay | Cost per signed case | Time to results | Best use | Main risk |
|---|---|---|---|---|---|
| Attorney referrals | Fee division with the referring lawyer | Little cash; a share of the fee | Months | Higher-value cases | Concentration in a few sources |
| Medical provider relationships | Time and service quality | Little cash | Months | Auto cases with treatment | Ethics rules on paid referrals |
| Past clients and reviews | Staff time | $0 to about $700 | Ongoing | Every firm | Slow to scale |
| Google Business Profile | Free; management time | Low | 2 to 4 months | "Near me" and city searches | Ranking volatility |
| Local Services Ads | Per lead, about $140 to $344 | About $1,000 to $4,700 | Days to weeks | Fast, verified visibility | Lead quality, limited control |
| Google Ads | Per click, $95 to $280 in Atlanta | About $2,900 to $8,800 | Days | Scale and case-type targeting | Waste without close management |
| SEO and content | Monthly program, often $2,000 to $10,000+ | About $900 to $1,200 once mature | 6 to 12+ months | Lowest long-run cost | Slow; competitive metros take longer |
| Social media | Per impression or lead form | Varies widely | Weeks | Awareness, retargeting, Spanish-language audiences | Lower intent |
| Software and time | Retention, not acquisition | Ongoing | Past-client referrals | Consent and frequency | |
| Directories and marketplaces | Listing fee or per lead | Varies | Weeks | Visibility, citations | Shared leads; rules on paid leads |
| Community marketing | Sponsorships and time | Hard to measure | Years | Brand and referral networks | No direct attribution |
| TV, radio, billboards, CTV | Media buys | About $2,000 to $6,000 (TV) | Months | Brand at scale | Cash-heavy, hard to attribute |

What marketing channel works best for personal injury lawyers?
Short answer
For most personal injury firms, the lowest cost per signed case comes from referrals (past clients, other attorneys and treating providers) and from local search visibility through Google Business Profile and reviews. The fastest paid channel is usually Google Local Services Ads, which charge per lead rather than per click. Google Ads scale furthest but cost the most per case. The best channel for a given firm is the one whose measured cost per signed case sits furthest below that firm's allowable cost.
Referrals from other attorneys
Family, criminal, estate and immigration lawyers regularly meet clients with injury claims they do not handle. A handful of reciprocal relationships can produce steady, higher-value cases at almost no cash cost. Fee division between lawyers in different firms is generally permitted when it is proportional to the work or each lawyer assumes joint responsibility, the client agrees in writing, and the total fee is reasonable (ABA Model Rule 1.5(e); confirm Georgia's version). The real cost is the fee share, so include it when comparing referral cases with marketed ones.
Medical provider relationships
Chiropractors, physical therapists and urgent care clinics see accident patients daily. The relationship that lasts is operational: reliable communication, organized records requests and prompt payment of the bills the firm is responsible for. It must never become paid referral. Paying anyone for recommending the firm is generally prohibited (see advertising rules). Track provider-sourced cases like any other channel; a single dominant provider is a concentration risk.
Past clients and reviews
A satisfied former client is the cheapest marketing a firm will ever have. Two habits make it systematic. First, ask for a review at the moment of greatest satisfaction, usually when the client receives the disbursement, with a direct link sent by text. Second, keep in touch: a short note at the anniversary of the case, a useful article, a holiday card. Reviews also feed the map pack and Local Services Ads ranking, so this channel improves two others.
Google Business Profile and the map pack
When someone searches "car accident lawyer near me," Google usually shows a map with three firms above the organic results. Those positions are driven by relevance, distance and prominence, and prominence leans heavily on review count, rating and recency. Choose "Personal Injury Attorney" as the primary category, add the case types you handle, keep name, address and phone identical everywhere they appear, post real photos, and answer every review. It costs nothing but attention and often produces the best-qualified calls a firm receives.
Local Services Ads for personal injury lawyers
Google's Local Services Ads appear above the regular ads with a "Google Screened" badge, and they charge per lead rather than per click. Published personal injury lead costs run from about $140 to $344 depending on market.6 Because the firm pays for contacts instead of clicks, LSAs are usually the fastest efficient paid channel for a smaller firm. Ranking depends partly on reviews and responsiveness, and leads that are not legitimate inquiries can be disputed for credit, so someone has to review them weekly.
Google Ads (PPC) for personal injury lawyers
Paid search reaches people the moment they search, at scale, and at a price. High-intent Atlanta terms are quoted at $95 to $280 per click.7 Run campaigns by case type, send each to a page about that case type rather than the home page, review search terms weekly, exclude work the firm does not take, and track calls, which make up most personal injury inquiries. Do not judge Google Ads by cost per lead; judge it by cost per signed case against your allowable number.
Personal injury lawyer SEO
Search engine optimization earns visibility in the organic results and the map pack without paying per click. It is slow, often six to twelve months in a competitive metro, and it compounds. The work falls into four areas:
- Local: Google Business Profile, reviews, and consistent listings in legal and general directories.
- Pages: one strong page per case type and location the firm actually serves, written for the injured person, not for the firm.
- Technical: fast mobile pages, working click-to-call, clean site structure, and structured data that describes the firm.
- Authority: links and mentions from local news, bar associations, legal publications and genuinely useful resources.
The same signals increasingly decide which firms appear in AI answers from Google, ChatGPT, Perplexity and Claude. Pages that answer a question directly, cite sources and use clear structure are easier for those systems to quote.
Content marketing
Content earns trust before the first call. The pages that bring in cases answer the questions injured people ask: what to do after a crash, how long a claim takes, how fees work, what happens if they were partly at fault, and how long they have to file. Publish fewer, better pieces, have an attorney review legal statements, and reuse each piece in email, social media and intake follow-ups.
Social media marketing for personal injury lawyers
Social platforms reach people before they need a lawyer, which makes them better at awareness and retargeting than at catching someone the day after a crash. They can work well for underserved audiences, including Spanish-speaking communities, when the firm can serve those clients in their language from the first call. Short videos that explain one useful thing outperform promotional posts. Measure social by signed cases, not followers.
Email marketing
Email is a retention channel. A quarterly note to past clients and referral partners keeps the firm in mind when a friend or patient needs a lawyer. Send only with permission, keep it useful, and never send case results that could identify a client.
Directories and legal marketplaces
Avvo, Justia, FindLaw, Martindale-Hubbell and Super Lawyers profiles add credibility, consistent citations and sometimes links. Paid lead marketplaces are different: many sell the same lead to several firms, and lawyer rules restrict paying for recommendations. A lawyer may generally pay the reasonable cost of advertising, but a lead service that recommends the lawyer or is paid per retained case raises rule questions that should be checked before signing.
Community marketing
Sponsorships, school safety programs, helmet giveaways and local charity work rarely show up in a cost-per-case report next month. Over years they build the name recognition that lowers the cost of every other channel, and they introduce the firm to future referral partners. Budget them as brand, cap them, and pick causes the firm's people will actually show up for.
Billboards, radio, television and connected TV
Mass media builds the recognition that makes people click the familiar name in search results and remember the firm when a friend is hurt. It is also the most cash-intensive and least attributable channel. It makes sense once search and intake already convert well and the firm can sustain a schedule for months. Connected TV and streaming offer market-targeted spots at a fraction of broadcast cost and a way to test before committing.
Intake and conversion: where marketing ROI is won or lost
Intake is the multiplier on every marketing dollar. Improving the share of leads that sign lowers the cost per signed case across every channel at once, without buying a single extra lead.
Using the funnel above: if intake lifts the lead-to-consultation rate from 60 to 70 percent and the consultation-to-signed rate from 25 to 30 percent, the same 100 leads produce 21 signed cases instead of 15. The cost per signed case falls from $2,000 to about $1,430, a 29 percent improvement with no change in marketing.
Why faster response times improve marketing ROI
Short answer
Injured people usually contact more than one firm, and the first firm that reaches them with a competent, caring conversation has the advantage. In a Harvard Business Review study of 1.25 million sales leads across industries, companies that contacted a lead within an hour were nearly seven times as likely to qualify it as those that waited longer, and more than 60 times as likely as those that waited a day or more. Faster response lowers the cost per signed case without raising spend.
That study covered sales leads generally, not law firms specifically,9 but law firm data points the same way. In Clio's 2024 secret shopper research, only 40 percent of firms answered prospective clients' calls and only 33 percent responded to emails.10 Every missed call is marketing money spent on a competitor's intake.
An intake checklist
- Answer live, every hour, including nights and weekends, or route to a trained answering service that books consultations.
- Measure speed to lead: minutes from inquiry to first real conversation. Aim for under five minutes during business hours.
- Follow up on every unconverted lead the same day and twice more that week.
- Offer intake in the languages your market speaks, from the first call.
- Use a short, consistent qualification script; leave detailed medical questions for after the firm is engaged.
- Explain fees, costs and liens plainly at signing. Confusion about money is a common reason clients leave mid-case.
- Record the source of every lead in the case management system so cost per signed case can be measured by channel.
How to measure personal injury marketing performance
Measure marketing at the level of signed cases and collected fees, by source, in groups signed in the same month. Clicks, impressions and leads are useful diagnostics but poor scorekeepers.
How do personal injury firms calculate marketing ROI?
Short answer
Marketing ROI is fee revenue attributable to marketing divided by the marketing spend that produced it. Because fees arrive months after cases sign, personal injury firms measure it two ways: projected ROI, which multiplies new signed cases by the expected fee per signed case as soon as they sign, and realized ROI, which counts fees actually collected from the cases signed in a given month once they resolve. A channel that looks strong on projected ROI and weak on realized ROI is signing cases that do not pay.
Attribution makes the calculation possible. Use call tracking with a distinct number per channel, keep form submissions tied to their source, and make "lead source" a required field in the case management system so every signed case and every fee carries its origin. Without that link, a firm is choosing channels by impression.
KPIs a personal injury firm should track
| KPI | Formula | Why it matters | Review |
|---|---|---|---|
| Leads by source | Count of inquiries per channel | Volume and mix | Weekly |
| Answer rate | Calls answered live ÷ inbound calls | Missed calls are lost spend | Weekly |
| Speed to lead | Median minutes from inquiry to first conversation | Drives conversion | Weekly |
| Cost per lead | Channel spend ÷ leads | Channel price, not value | Monthly |
| Lead-to-consultation rate | Consultations ÷ leads | Lead quality and intake reach | Monthly |
| Consultation-to-signed rate | Signed cases ÷ consultations | Case fit and intake skill | Monthly |
| Cost per signed case, by channel | Channel spend ÷ signed cases from that channel | The core efficiency number | Monthly |
| Signed cases per month | New signed cases | Growth and capacity planning | Monthly |
| Expected fee per signed case | Average settlement × fee % × recovery rate | Sets the allowable cost | Quarterly |
| Recovery rate | Resolved cases that paid a fee ÷ resolved cases | Corrects survivorship bias | Quarterly |
| Realization rate | Fees collected ÷ fees projected at signing, by month signed | Tests the pipeline's honesty | Quarterly |
| Signing-to-fee time | Median months from signing to fee received | Cash planning | Quarterly |
| Marketing as % of fees | Trailing 12-month spend ÷ trailing 12-month fees | Budget discipline | Quarterly |
| Realized ROI by month signed | Fees from a month's signed cases ÷ that month's spend | True profitability by channel | Quarterly |
| Open cases per case manager | Open cases ÷ case managers | Capacity before adding spend | Monthly |
How marketing strategy changes with firm size
The right mix depends less on ambition than on what constrains the firm: attorney time for a solo practice, intake coverage for a small team, capacity and attribution for a growing firm, and rising marginal cost per case for an established one.
| Firm | Signed cases a month | Fees a year | Monthly budget | Lead channels | Binding constraint |
|---|---|---|---|---|---|
| Solo attorney | About 2 | About $255,000 | $2,000 to $4,000 | Attorney and provider referrals, Google Business Profile, reviews, a small Local Services Ads budget | Attorney time and cash |
| Attorney and a case manager | About 5 | About $740,000 | $6,000 to $12,000 | Local Services Ads, one or two case-type Google Ads campaigns, SEO foundation | After-hours intake |
| Small team | About 12 | About $1.8 million | $15,000 to $30,000 | Diversified paid search, a content program, a structured referral program | Attribution and intake staffing |
| Established firm | About 30 | About $4.8 million | $40,000 to $80,000+ | All of the above plus brand: connected TV, radio, outdoor | Rising marginal cost per case; capacity |
A practical marketing budget framework
Set the budget from the bottom up, in this order, and revisit it monthly.
- Find your expected fee per signed case. Use resolved cases from the last 12 to 24 months, including the ones that paid nothing.
- Set the allowable cost per signed case. Subtract the cost to work a case and the contribution each case must leave behind.
- Decide how many added cases a month the team can absorb. Multiply by your signing-to-fee time to see how many extra open files that creates.
- Multiply to get the ceiling. Allowable cost per signed case × absorbable cases a month = maximum sustainable budget.
- Check the cash. Make sure cash on hand, less a reserve, covers the months of spend before the new fees arrive.
- Check the percentage. Compare the result with the 10 to 20 percent band. Far outside it is a reason to recheck the inputs.
- Allocate across channels and measure each by cost per signed case for at least three months before moving money.
| Layer | Monthly | What it buys |
|---|---|---|
| Foundation | $3,000 | Website, SEO and content, Google Business Profile, reviews, call tracking |
| Paid acquisition | $5,000 | Local Services Ads ($3,000) and one case-type Google Ads campaign ($2,000) |
| Relationships and community | $1,250 | Referral partner events, client appreciation, one local sponsorship |
An example, not a prescription. The split should follow measured cost per signed case once three months of data exist.
How to decide when to increase marketing spend
Increase spend when the next dollar is likely to sign a case below the allowable cost and the firm can carry and fund the result. All five conditions below should hold.
- Cost per signed case has stayed at or below the allowable figure for three consecutive months in the channel you plan to grow.
- Intake is not the bottleneck: answer rate above 90 percent and stable consultation-to-signed rates.
- The team has room for the added open files the new intake creates over the next year, or the hire is already planned.
- Cash covers the lag: the cash rule in the calculator stays above your reserve at the higher budget.
- Realized fees are tracking projections for cases signed six to twelve months ago.
Raise budgets in steps of 20 to 25 percent and watch the cost per signed case of the added spend, not the blended average. In most paid channels each additional case costs more than the last. When the marginal cost crosses the allowable cost, stop and put the next dollar into intake, reviews or a cheaper channel.
Common personal injury marketing mistakes
- Judging channels by cost per lead. A $50 lead that signs 2 percent of the time costs $2,500 per case; a $400 lead that signs 25 percent of the time costs $1,600.
- Setting the budget as a percentage alone. Ten percent of revenue can be too much for a firm with low case values and too little for one with spare capacity.
- Ignoring the lag. Growth that the fee math supports can still run the firm out of cash in months four through nine.
- Buying more cases than the team can work. Overloaded case managers slow every file, lose clients and depress settlement values.
- Missing calls. After-hours and weekend gaps waste the most expensive leads a firm buys.
- No lead source in the case management system. Without it, cost per signed case by channel cannot be measured.
- Treating projected values as revenue. Pipelines are often dominated by one or two large cases; plan on realized averages.
- Depending on one channel. A policy change, an algorithm update or one lost referral source can halve intake.
- Sending paid traffic to the home page. Each case type needs its own page and message.
- Quitting SEO at month four. The investment pays in months six through eighteen.
- Advertising cases the firm does not want. Every unwanted case type in a campaign raises the cost of the wanted ones.
- Paying for referrals. It risks bar discipline.
Advertising and referral rules for Georgia personal injury firms
Marketing rules for lawyers are set by each state. Georgia's Rules of Professional Conduct follow the ABA Model Rules in structure but differ in detail and numbering, so confirm current text with the State Bar of Georgia before launching a campaign.
- No false or misleading communications. ABA Model Rule 7.1 and its Georgia counterpart prohibit misleading claims, including unqualified past results presented as predictions.
- No paying for recommendations. ABA Model Rule 7.2(b) generally prohibits giving anything of value for recommending a lawyer, with exceptions for the reasonable cost of advertising, qualified referral services, nominal thank-you gifts and certain non-exclusive reciprocal referral arrangements disclosed to the client.11
- A 30-day window for written solicitation. Georgia's Rule 7.3 restricts written communications to accident victims or their relatives about a personal injury or wrongful death within 30 days of the accident, and prohibits in-person and live telephone solicitation of people who have not sought advice.13
- Fee division between lawyers is governed by Rule 1.5(e) and requires written client consent.

Frequently asked questions
How much should a personal injury law firm spend on marketing?
Most personal injury firms spend 10 to 20 percent of gross fee revenue, with growth-stage and rebuilding firms at 20 to 25 percent. The right figure is the lower of what the fee math allows (allowable cost per signed case × cases the team can absorb) and what the firm's cash can sustain until the new cases pay.
What is a good cost per signed personal injury case?
Any cost below your allowable cost per signed case. For a typical one-third fee on a $35,000 average settlement, that often lands between $2,000 and $4,000. Published paid-channel benchmarks range from about $1,000 to more than $5,000.
How long does personal injury marketing take to pay back?
Paid channels produce signed cases within weeks, but fees arrive when cases resolve, often six to twelve months later. A firm that starts a new budget should expect cumulative payback in roughly the second year, and plan cash for the gap.
How do I get more personal injury cases without spending more?
Convert more of the leads you already have: answer every call live, respond within minutes, follow up the same day, and offer intake in your clients' languages. Then ask every satisfied client for a review and a referral, and build reciprocal relationships with attorneys who see injury cases they do not handle.
Should a small personal injury firm start with Google Ads or Local Services Ads?
Most small firms start with Local Services Ads because they charge per lead, appear above other ads and are simpler to manage. Google Ads come next, usually one case type at a time, once intake converts well and the firm knows its allowable cost per signed case.
How long does SEO take for a personal injury firm?
Typically six to twelve months for meaningful results in a competitive metro, sometimes longer, with local map visibility often improving sooner. SEO is an ongoing investment whose cost per case keeps falling as rankings mature.
Is it legal to pay for personal injury leads or referrals in Georgia?
Lawyers may generally pay the reasonable cost of advertising, but paying someone to recommend the firm is generally prohibited under the rules of professional conduct. Lead services should be reviewed against the current Georgia rules before the firm signs up.
What KPIs matter most for personal injury marketing?
Cost per signed case by channel, consultation-to-signed rate, speed to lead, recovery rate and realized ROI by month signed. Together they show what a case costs, whether intake converts it, and whether it actually pays.
