Quick answer: Legal services is the most expensive industry on Google Ads: $9.87 per click and $131.63 per lead on average in WordStream’s 2026 US data. Law firms win with tightly themed practice-area campaigns, Local Services Ads where available, fast intake, and tracking cases signed rather than calls.
One signed personal injury, family law or criminal defence matter can be worth more than a year of ads, which is why competition is so fierce. Firms that win treat intake as part of advertising: the call is answered, qualified and followed up within minutes.
What ads cost for law firms
| Benchmark | Avg. cost per click | Conversion rate | Avg. cost per lead |

Attorneys & Legal Services tops WordStream’s 2026 benchmarks for both cost per click ($9.87) and cost per lead ($131.63), with a 5.55% conversion rate. In major US metros, personal injury keywords can cost far more than the average.

Example ads you can adapt
On Meta, don’t imply the viewer is going through a divorce, has been injured or has been charged. That breaches the personal attributes policy.
What the landing page needs
- Practice-area specific page per campaign
- Lawyer profiles and admissions
- Fee structure or how fees work
- Confidential enquiry form and click-to-call
- Reviews where your professional rules allow them
Full list: landing page checklist.
Track the right things
- Qualified calls and forms (intake-screened)
- Consultations booked
- Matters signed and fee value per campaign
Platform rules that apply to law firms
- Professional conduct rules on legal advertising (bar associations, law societies, the SRA) apply on top of platform rules: testimonials, “specialist” claims and outcome claims are often restricted.
- Local Services Ads for lawyers use Google Screened checks (licence, background) where available.
- Meta personal attributes: no copy implying the viewer’s legal situation, finances, or criminal record.
Common mistakes
- Mixing practice areas in one campaign
- No intake process, so expensive calls go to voicemail
- Measuring calls, not signed matters
- Broad match on “lawyer” pulling job seekers and students
How much to spend
Work backwards from the number of enquiries you can handle. Monthly budget ≈ target leads × expected cost per lead. At the Attorneys & Legal Services average of $131.63 per lead, 20 leads a month is roughly $2,633 in ad spend before management fees.
Small firms in competitive cities often need $3,000 to $10,000+ a month per practice area to get enough data. Niche practice areas and smaller markets can start lower.
Frequently asked questions
Why are Google Ads so expensive for lawyers?
Legal matters are high value, so many firms bid on the same terms. Legal has the highest average cost per click and per lead in WordStream’s 2026 report.
Are Local Services Ads good for lawyers?
Often yes: you pay per lead and appear above Search ads with a Google Screened badge. Availability depends on country and practice area.
Can lawyers use Facebook ads?
Yes, for awareness and suitable practice areas, but copy must not imply the viewer’s situation, and your professional rules still apply.
