Legal is the most expensive CPC vertical globally. Personal injury keywords hit $20–$50 per click because a single case can generate $50,000–$500,000 in fees. The economics are extreme: a law firm that closes 1 in 50 leads at an average case value of $25,000 can justify paying $500 per lead — making a $6.75 average CPC look cheap.

Legal Services Advertising: What Drives the Numbers
Legal services advertising is the most expensive digital ad vertical by CPC, driven almost entirely by the economics of contingency fee personal injury litigation. A single personal injury case generates $25,000–$500,000 in fees. At a 2% lead-to-case close rate, a firm can pay $500–$5,000 per lead and still achieve strong ROI. This bidding capacity makes Google Search the most competitive and expensive auction outside financial services insurance terms.
Practice area economics vary enormously. Personal injury (car accidents, slip-and-fall, medical malpractice) commands the highest CPCs — $15–$50 for primary terms in major metros like New York, Los Angeles, and Chicago. Corporate and business law CPCs are lower ($3–$8) but still above most other verticals. Family law and criminal defense sit at $4–$12 depending on location.
Geography drives significant CPC variation. New York City and Los Angeles personal injury CPCs can reach $60–$80+ for primary terms. Smaller metros and rural markets run 40–70% below major city rates. Location-specific bidding strategies and local landing pages are essential for cost efficiency in legal advertising.
