Marketing Attribution for Legal
DIRECT ANSWER
Marketing attribution is the process of assigning credit for a sale or conversion to one or more marketing touchpoints a customer encountered before converting. Models range from single-touch (first or last click) to algorithmic multi-touch, with accuracy improving as data volume and measurement sophistication increase. For Legal companies, this matters because Google CPCs for personal injury and mass tort keywords routinely hit $200–$500 per click, making paid search uneconomical without precise intake funnel optimization.
What marketing attribution means for Legal
Legal marketing is bifurcated between high-volume consumer litigation (PI, immigration, criminal defense — where paid search dominates and intake speed is the primary conversion variable) and sophisticated B2B practice groups (M&A, IP, employment — where thought leadership, speaking engagements, and relationship CRM drive originations). These two motions require completely different teams, budgets, and measurement frameworks.
For Legal teams the relevant marketing pains are: Google CPCs for personal injury and mass tort keywords routinely hit $200–$500 per click, making paid search uneconomical without precise intake funnel optimization; State bar advertising rules prohibit testimonials, superlatives, and certain guarantees — creative that converts in other verticals is non-compliant in legal; Intake-to-retainer conversion tracking requires CRM integration most small firms lack, making true CAC invisible; Reputation management is critical but attorney review solicitation is ethically constrained in many states. State Rules of Professional Conduct (Model Rules 7.1–7.3) restrict advertising claims, solicitation, and referral fees; vary significantly by state; some states require prior submission of ads to bar for review.
Attribution Models and Their Trade-offs
The six core attribution models are: last-touch (100% credit to the final touchpoint), first-touch (100% to the first), linear (credit split evenly), time-decay (more credit to recent touches), position-based (U-shaped: 40% first, 40% last, 20% middle), and data-driven (algorithmic, trained on your actual conversion paths). Last-touch is the default in most ad platforms and consistently overstates the role of bottom-funnel paid search.
Data-driven attribution requires a minimum conversion volume — Google Ads needs roughly 3,000 conversions per month across the conversion action for its model to stabilize. Below that threshold, position-based is usually the most defensible manual model. B2B companies with long sales cycles (60–180 days) often need account-level multi-touch attribution layered over CRM data because session-based models break on multi-session, multi-stakeholder journeys.

FAQ
Marketing Attribution for Legal — common questions
Which attribution model should I use?
Start with position-based (U-shaped) if you lack the volume for data-driven. If you run high-volume paid campaigns, switch to data-driven attribution inside your ad platform. For strategic budget decisions, layer in a media mix model — platform attribution systematically overclaims for channels it can measure directly.
How does marketing attribution differ for Legal companies?
The fundamentals are the same, but Legal marketing carries specific constraints — Google CPCs for personal injury and mass tort keywords routinely hit $200–$500 per click, making paid search uneconomical without precise intake funnel optimization and State Rules of Professional Conduct (Model Rules 7.1–7.3) restrict advertising claims, solicitation, and referral fees; vary significantly by state; some states require prior submission of ads to bar for review.. CoMo adapts execution to that context automatically.
