How to Track Cost Per Acquisition for Legal
Every client costs money to acquire. Whether you’re running Google Ads, sponsoring events, or paying for referrals, knowing your cost per acquisition determines whether you’re growing or just spending. Law firms that don’t track this often waste half their marketing budget.
Why Cost Per Acquisition Matters for Legal
Case values vary wildly. A personal injury case might be worth $50,000 while a simple contract review is $500. Your CPA targets must reflect case value, not just client count.
Marketing channels are expensive. Legal keywords are among the most competitive in advertising. Without tracking CPA, you might be bidding on terms that never convert.
Referrals are golden but need tracking. Many clients come from existing client referrals. Tracking whether your referral program costs less than paid acquisition helps allocate budget.
Client quality matters. Not all clients are worth the same. A client with a strong case generates more revenue than one who ghosts after the consultation.
How to Check in GA4
Set up conversion tracking for “Contact Form Submit,” “Phone Call,” and “Case Inquiry” in GA4. Link your Google Ads account to import cost data automatically. Create unique landing pages for each practice area and campaign.
Calculate CPA by taking your spend on each channel and dividing by the number of cases or consultations booked. For longer sales cycles, track cost per lead first, then calculate downstream CPA.
The Easier Way
ClawAnalytics pulls together data from your ad platforms, website, and intake system. You can see which channels bring cases that actually sign. Questions become simple: “Is our Google Ads spend generating cases?” or “Which practice area should we market more?”
For example, you might find that Google Ads for slip-and-fall cases cost $300 per case while car accident ads cost $200. Or that your newsletter brings referrals at no cost. ClawAnalytics makes this visible.
Quick Wins
-
Use separate intake phone numbers for each channel. This is the easiest way to track which source brings calls.
-
Ask every new client how they found you. Compare their answer to your marketing data to spot discrepancies.
-
Track cost per case, not just cost per lead. A cheap lead that never becomes a case is expensive in the end.
-
Focus on high-value practice areas. If family law cases pay less than personal injury, your CPA targets should differ.
