What is the regulatory frame?
In most United States jurisdictions, lawyer advertising is governed by state rules patterned on the ABA Model Rules of Professional Conduct: the prohibition on false or misleading communications about the lawyer or services (the 7.1 family), rules on advertising and identification (the 7.2 family, including specialization claims), and limits on direct solicitation of specific persons (the 7.3 family). States vary meaningfully - some add filing or review requirements, disclaimers, and stricter testimonial rules - so the operating rule for any campaign is: the state bar's version controls, and marketing decisions that touch these families get checked against it, not against the model rule from memory.
Where does the measurement stack touch these rules?
| Stack element | Rule family it touches | The review question |
|---|---|---|
| Landing page claims and dynamic copy | False or misleading (7.1) | Can every results-flavored statement be substantiated, including variants a test tool generates? |
| Retargeting audiences | Solicitation boundaries (7.3) | Does the targeting approach a specific person known to need legal services in a particular matter, or advertise generally? |
| Reviews and testimonial widgets | 7.1 plus state testimonial rules | Are endorsements presented per the state's disclaimer and authenticity requirements? |
| Call recordings and transcripts | Confidentiality duties | Prospective-client communications are protected - who holds them, and under what agreement and retention? |
| Intake and CRM records | Confidentiality duties | Does prospective-client information leak into marketing tools via integrations and pixels? |
Is retargeting solicitation?
The line the rule families draw is between advertising to the world and targeting a specific person the lawyer knows needs representation in a particular matter. General retargeting of practice-area page visitors sits on the advertising side in most analyses; the posture sharpens as targeting narrows toward identified individuals with known legal needs - custom audiences built from intake lists being the clearest case to review with ethics counsel before launch. The measurement-layer discipline that keeps this defensible: know exactly which audiences exist, from what data, refreshed how - which is an inventory question your stack should be able to answer on demand.
The confidentiality sleeper: firms review ad copy carefully and then pipe intake form contents into marketing automation, load client lists into ad platforms for lookalikes, and let session tools record intake conversations - each a disclosure of prospective-client information to a vendor. The ethics review that covers the billboard should cover the data flows; in audits, the flows are where the surprises live.
What review posture keeps campaigns defensible?
- A claims register: every marketing statement that asserts results, specialization, or superiority, with its substantiation and its state-rule check, dated.
- An audience register: every retargeting and custom audience, its source data, and its ethics review status.
- A data-flow inventory: what the site and intake stack transmit to which vendors - the runtime capture, read jointly by marketing and ethics counsel.
- State-rule mapping: for each state where the firm advertises, the local deltas from the model rules that bind these registers.
None of this slows a competent campaign; all of it shortens the conversation when a bar inquiry, a competitor grievance, or a new managing partner asks how the machine works.
