Client: Riverside Injury Law · Market: Chicago, IL Metro · Timeframe: 75 Days
Legal advertising on Google is among the most expensive paid media in any industry. Average CPCs for personal injury keywords in major metros range from $40 to $120 per click. Riverside Injury Law, a boutique PI firm in Chicago specializing in car accidents, truck accidents, and slip-and-fall cases, knew this. What they didn't know was that a significant portion of their $31,000 monthly Google Ads budget was going to clicks from people searching for criminal defense, DUI attorneys, and general legal advice — none of whom would ever become PI clients.
When David, the managing partner, brought us in, the audit showed a campaign structure that had never been properly scoped to the firm's practice areas. There was one Search campaign, "Injury Lawyers Chicago," running on modified broad match keywords. The search term report was a horror show: "accident lawyer" traffic was mixed with "lawyer jokes," "how to fight a speeding ticket," and "what to do if falsely accused" queries.
David was also not running Google's Local Services Ads (LSA) — the Google Guaranteed placement that appears above all paid search results for legal queries. For personal injury, LSA leads are pay-per-lead (not pay-per-click) and consistently produce the lowest cost per qualified inquiry in the legal vertical.
LSA for law firms requires Google verification including bar number validation, malpractice insurance verification, and background check completion. We managed the full setup process:
One hidden problem: the firm was counting all form submissions as "leads" including clearly non-qualifying inquiries. We built a qualification scoring system that tracked which leads actually made it to a consultation — allowing us to optimize toward qualified case leads, not raw form fills. This changed the optimization signal entirely and gave the algorithm data to learn from that actually predicted firm revenue.
| Metric | Before BZM | After 75 Days |
|---|---|---|
| Cost per case lead | $940 | $218 |
| Qualified case leads/month | 33 | 112 |
| Monthly ad spend | $31,000 | $31,000 (same) |
| LSA running | No | Yes — Google Guaranteed active |
| Negative keywords | ~40 (incomplete) | 580 (comprehensive) |
| Practice area campaign separation | None (1 campaign) | 4 campaigns segmented |
| Qualification tracking | Raw form fills only | Full consultation funnel tracked |
"Legal advertising on Google is brutally expensive if you don't know what you're doing. We were paying almost $1,000 per case lead and couldn't figure out why. BZM identified that a huge chunk of our ad spend was going to people researching DUIs and criminal defense — not PI cases at all. After the restructure and the LSA launch, our cost per qualified case lead dropped to the $200s. That's transformational for our firm's economics. We can now take more cases and build the practice the way we always wanted to." — David R., Managing Partner, Riverside Injury Law · Chicago, IL
Personal injury is one of the most competitive paid media verticals in existence. The firms winning on Google are not necessarily spending more — they're spending smarter. LSA is the most underutilized tool in the legal advertising stack. Most PI firms either don't know it exists or haven't completed the verification process. The 30 days of setup work pays for itself in the first month of leads.
We will audit your current legal advertising account free of charge and show you the true cost per qualified case lead, where spend is leaking, and whether LSA is the right addition to your strategy.
