What Law Firms actually pay
| Metric | Typical range | What "good" looks like | Source |
|---|---|---|---|
| Cost per lead | $18.17 on Meta lead ads · $131.63 on Google Search | Under $20 on Meta, under $135 on search. Search is the priciest category LocaliQ measures — that is the category, not your account. | LocaliQ / WordStream, 2025 |
| Cost per 1,000 impressions (CPM) | About $15.14 on Meta | $12–$18 — one of the more expensive reaches in this set, because legal advertisers bid hard for attention. | LocaliQ / WordStream, 2025Derived: $0.86 traffic CPC × 1.76% traffic CTR × 1,000. LocaliQ publishes no CPM column. This figure is derived from its traffic-campaign CPC and CTR for the category, because CPM is exactly CPC × CTR × 1,000. |
| Click-through rate | 2.11% on Meta lead ads · 5.87% on Google Search | Above 2% on Meta. Practice-area-specific creative materially outperforms firm-brand creative here. | LocaliQ / WordStream, 2025 |
| Cost per click | $4.10 on Meta lead ads · $9.87 on Google Search | Search under $10. Legal has the highest search cost per click of any category LocaliQ publishes, against a $5.42 all-industry average. | LocaliQ / WordStream, 2026 |
| Landing-page / form conversion rate | 10.53% on Meta lead ads · 5.55% on Google Search | Above 10% on Meta — the highest Meta lead-gen conversion rate of the ten industries here. | LocaliQ / WordStream, 2025 |
Break-even ROAS for Law Firms
1.82× is 1 ÷ a 55% gross margin. On the assumptions below Meta returns 15.4× and Google Search 2.13× — just 17% above break-even. Because average matter value varies more in legal than in any other category here, treat the multiple as a method rather than an answer and substitute your own numbers.
The assumptions behind those two numbers
| Input | Assumed value | Basis |
|---|---|---|
| Average ticket | $3,500 per signed matter | Assumption, and a crude one. Matter values in this category span a $750 will and a six-figure personal-injury settlement, and no credible published average exists across that range. A PI firm should use a far larger number and a much lower close rate. |
| Gross margin | 55% | Assumption. Attorney and paralegal time is the dominant cost. A contingency practice carries case costs that make this materially worse before a settlement lands. |
| Repeat rate | 1 matter per client | Assumption. Most consumer legal matters are one-and-done; referrals from satisfied clients are real but are not repeat purchases and should be counted separately. |
| Close rate | 8% of leads become signed matters | Assumption. Legal intake volume is dominated by people outside the firm's practice area or jurisdiction, so the gap between an inquiry and a signed matter is unusually wide. |
Worked example
- Assumptions: $3,500 per signed matter, a 55% gross margin, one matter per client, and 8% of leads signing.
- Break-even ROAS is 1 ÷ 0.55 = 1.82×.
- One lead is worth 0.08 × $3,500 = $280.
- Against the $18.17 Meta lead that is 15.4× — the widest margin of any industry on this site. Against the $131.63 Google Search lead it is 2.13×, only 17% above break-even.
- Break-even cost per lead is $280 × 0.55 = $154. Meta uses 12% of that headroom; search uses 85% of it.
- Now change one assumption. At a 5% close rate instead of 8%, break-even cost per lead falls to $96 — below what Google Search actually costs, so search goes underwater while Meta still returns 9.6×. Intake quality, not bidding, is what decides whether legal search advertising works.
What moves these numbers
- State bar advertising rules, which are the binding constraint and differ by state. In Florida, Rule 4-7.19(a) requires most advertisements to be filed with the Bar at least 20 days before first use, with a $250 fee rising to $750 when filed late, while Rule 4-7.20 exempts a firm's own website. Check the rules of every state you are licensed in before writing a single ad.
- Practice-area separation. A family-law lead and a personal-injury lead cost similar amounts and are worth wildly different sums.
- Intake. An 8% close rate on inquiries is generous in most firms, and the difference between 5% and 8% flips whether search is profitable at all.
- Jurisdiction targeting. Legal leads from outside the states you are licensed in are pure waste, and they arrive constantly.
- The Meta-to-search gap itself. A $18.17 lead against a $131.63 lead is the largest published arbitrage in this set, and most firms still spend the majority of their budget on the expensive side.
Frequently asked
How much does a law firm lead cost in 2026?
$18.17 on Meta lead ads and $131.63 on Google Search. Legal is the most expensive category LocaliQ publishes for search, at $9.87 per click against a $5.42 all-industry average, while Meta sits among the cheapest.
What is a good ROAS for a law firm?
Break-even on a 55% gross margin is 1 ÷ 0.55 = 1.82×. At a $3,500 matter and an 8% close rate, Meta returns about 15.4× and Google Search about 2.13×. Target 3.6×, and substitute your own matter value — legal case values vary more than any other category here.
What is the break-even cost per lead for a law firm?
About $154 at an 8% close rate on a $3,500 matter with a 55% margin. At a 5% close rate it falls to $96 — below the $131.63 that Google Search costs, which is how a firm can run a technically healthy search account at a loss.
Do state bar rules affect how a law firm can run ads?
Yes, and they are the real constraint. Rules are state-specific. Florida's Rule 4-7.19(a), for example, requires most advertisements to be filed with the Bar at least 20 days before first use for $250, rising to $750 if filed late, while Rule 4-7.20 exempts the firm's own website. Verify the rules in every state you practise in.
Is Facebook or Google better for a law firm?
On cost, Meta by a factor of seven — $18.17 against $131.63 — and it converts twice as well at 10.53% versus 5.55%. Search still matters because someone typing 'DUI lawyer near me' has immediate intent, but most firms over-weight it relative to what the numbers support.
What CPM should a law firm expect on Meta?
About $15.14 per 1,000 impressions, derived from the $0.86 traffic cost per click and 1.76% traffic click-through rate LocaliQ publishes. That is at the expensive end for a local category, reflecting how hard legal advertisers compete for attention.
