What Law Firms actually pay
| Metric | Typical range | What "good" looks like | Source |
|---|---|---|---|
| Cost per lead | $18.17 on Meta lead ads (LocaliQ 2025 edition) · $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. The 2026 Facebook edition no longer publishes a legal lead row, so the Meta figure is the 2025 edition's. | LocaliQ / WordStream, 2025 |
| Cost per 1,000 impressions (CPM) | About $12.21 on Meta | $10–$15 — at the more expensive end of this set, because legal advertisers bid hard for attention. | LocaliQ / WordStream, 2026Derived: $0.69 traffic CPC × 1.77% 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 (LocaliQ 2025 edition) · 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 (LocaliQ 2025 edition) · $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 (LocaliQ 2025 edition) · 5.55% on Google Search | Above 10% on Meta — the second-highest lead-ad conversion rate in LocaliQ's 2025 edition, against that edition's 7.72% all-industry average. | 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× at the 2025-edition lead cost 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 (LocaliQ 2025 edition) that is 15.4×. 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. An $18.17 Meta lead (LocaliQ 2025 edition) against a $131.63 search lead is one of the largest published gaps 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?
$131.63 on Google Search and $18.17 on Meta lead ads — the Meta figure from LocaliQ's 2025 edition, because the 2026 edition no longer publishes a legal lead row. Legal is the most expensive category LocaliQ publishes for search, at $9.87 per click against a $5.42 all-industry average, while on Meta it sat among the cheapest in 2025.
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× on LocaliQ's 2025-edition lead cost 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 (LocaliQ 2025 edition) against $131.63 — and it converted nearly 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 $12.21 per 1,000 impressions, derived from the $0.69 traffic cost per click and 1.77% traffic click-through rate in LocaliQ's 2026 edition. That is above the roughly $11.58 the all-industry traffic averages imply, reflecting how hard legal advertisers compete for attention.
