Before citing any number from this page, understand where it comes from and what it does not tell you. The benchmarks here draw on three sources: publicly available keyword research tools (Google Keyword Planner and third-party SEO platforms), legal industry marketing reports published by organizations including the Legal Marketing Association and industry trade press, and patterns observed across campaigns AuthoritySpecialist has managed for defense-focused law firms. Where a figure comes from those campaign observations, the text says so, without attaching client counts or invented precision to it.
Read the figures as orientation for budget and intake planning. They show the scale of auction costs, search behavior, and conversion rates a DUI defense practice is working with, and each section below explains how to compare the relevant numbers with the firm's own market, campaign, and intake data.
Geographic variation is large. A DUI keyword that costs $60 per click in a mid-size Midwestern city may exceed $180 in Los Angeles or New York. No single number applies everywhere, so collect current geo-specific auction data before a firm commits budget.
Firm-level variables matter. Intake speed, brand recognition, attorney reviews, and landing page quality all affect conversion rates independent of traffic source. Phrases such as conversion rate, cost per lead, retained client, local visibility, and organic performance can also be calculated differently across firms, so a defense practice should define a qualified inquiry, consultation, retained matter, attribution window, duplicate lead, and channel source before comparing its own results with any benchmark.
Data freshness shifts. CPC benchmarks move with advertiser competition, and search volumes fluctuate seasonally and with legislative changes affecting DUI enforcement. Paid auction costs, search demand, local results, and conversion behavior can change, so this page is updated periodically; pull current keyword data, paid-search reports, and first-party intake data before making live budget decisions.
Regulatory boundary: this is educational content, not legal or accounting advice. Marketing analysis should remain separate from legal or ethics approval, and responsible legal or regulatory reviewers remain required where their review is relevant; no benchmark page can certify compliance.
With that context in place, the figures below provide a useful orientation for budgeting, prioritizing keywords, and setting acquisition expectations, not a guarantee of what a firm will experience.
