If you’re a personal injury attorney considering Google Ads, the honest answer up front is: it’s the single most expensive advertising category on the platform. Real numbers help more than vague warnings, so here’s what firms actually pay in 2026.

Average Cost Per Click for Legal Keywords

Attorneys and legal services carry the highest average cost-per-click of any industry tracked, coming in at $9.87 according to WordStream’s 2026 Google Ads Benchmarks report, up 15% from the prior year. That figure blends every type of legal search, including low-competition and informational queries, so it understates what personal injury specifically costs.

What Personal Injury Keywords Actually Cost

Once you narrow to high-intent personal injury terms in competitive markets, costs climb sharply:

Google Ads Cost Per Click for Legal Keywords (2026)

Keyword Type	Typical Cost Per Click
Blended legal industry average	$9.87
Personal injury (national average)	$9.30
High-intent personal injury (competitive metros)	$150 – $500+
Mass tort / catastrophic injury terms	$250 – $1,000+

Generic phrases like “car accident lawyer” regularly exceed $150 per click in competitive metro areas, and some high-value terms tied to catastrophic injury cases have reached $300 to $500 per click.

Cost Per Lead, Not Just Cost Per Click

Click cost only tells part of the story. According to LocaliQ’s legal industry benchmarks, personal injury campaigns convert at an average rate of 5.45%, producing an average cost per lead of $159.17. That number varies widely by market and campaign quality, but it’s a more useful planning figure than CPC alone, since it accounts for how many clicks actually turn into a case inquiry.

What Actually Drives the Cost

A few factors explain why personal injury sits at the top of every cost benchmark:

• Case value justifies the spend. A single signed case can be worth tens of thousands of dollars in fees, so firms are willing to bid aggressively for a click that might become a client.
• Market competition. Dense attorney populations push costs far above national averages, since firms are bidding against each other for the same searches.
• Keyword intent. A specific, ready-to-hire search costs more than a broad informational query, because it converts at a much higher rate.
• Quality Score. Google rewards well-structured campaigns and relevant landing pages with lower costs per click, meaning two firms bidding on the same keyword can pay very different amounts.

Typical Monthly Budgets by Firm Size

Most firms don’t run a single keyword in isolation; they budget across a campaign. General ranges reported across the industry: solo and small firms typically budget $2,000 to $5,000 per month, mid-size firms $5,000 to $15,000 per month, and multi-market practices $25,000 to $100,000 or more per month. Budget size alone doesn’t determine results; campaign structure and bid strategy matter as much as the dollar amount behind them.

Making the Math Work

High CPC isn’t a reason to avoid Google Ads; it’s a reason to run campaigns with more precision than a lower-cost industry would require. Firms that focus spend on tightly matched keywords, strong Quality Scores, and conversion tracking can compete profitably even at $150+ per click, while firms treating it as a set-and-forget channel tend to overpay for the same results. You can see how we approach Google Ads and PPC management for law firms here.

Google Ads costs for personal injury attorneys are genuinely the highest in the industry, but the number that matters most isn’t the cost per click, it’s the cost per signed case, which is a function of strategy as much as budget. Firms weighing PPC against organic growth may also want to look at our law firm SEO approach as a complementary channel.
