Start with the diagnosis, not the service menu

A credible partner should be able to explain why a channel or rebuild is appropriate for the firm’s practice mix, markets, economics, capacity, and current constraints. If the recommendation appears before those conditions are understood, the proposal may reflect what the agency sells rather than what the firm needs.

Ask what evidence would cause the agency to recommend against its own service. The answer reveals whether the strategy includes suitability criteria or whether every conversation is expected to reach the same scope.

Interrogate the measurement model

Request the exact definitions used for lead, qualified opportunity, consultation, and signed matter. Ask which systems hold each stage, how calls and forms are attributed, how duplicate or spam contacts are handled, and what the agency needs from intake. A report can look precise while hiding inconsistent definitions.

No partner should imply that attribution is perfect. A stronger answer explains what can be observed directly, what is modeled, what is missing, and how decisions will be made despite uncertainty.

Verify proof and the limits of that proof

Case studies should identify the starting condition, market, practice area, time period, scope, implementation dependencies, and the metric being reported. A percentage without the denominator or a revenue figure without attribution context may be more persuasive than informative.

Ask whether the client can be named, whether results were independently verified, and which conditions were unusual. The agency should be equally clear about what it cannot promise. Guarantees of rankings, leads, or cases are a warning sign in a market controlled by competitors, platforms, prospects, courts, and the firm’s own operations.

Understand ownership, access, and exit conditions

The firm should know who owns ad accounts, analytics, domains, profiles, creative, code, content, call numbers, and historical data. It should also know what happens to each asset at the end of the engagement. Operational dependence can become expensive when access is unclear.

Ask who performs the work, who reviews legal content, how changes are approved, how incidents are escalated, and what the communication cadence includes. A polished strategist in the sales process does not prove that the operating team has the same expertise.

Evaluate commercial alignment

Pricing should be understood in relation to scope, risk, market complexity, and ownership. Low cost can indicate narrow execution, while high cost does not guarantee senior attention or commercial insight. Ask what is included, what depends on the firm, what creates additional fees, and how priorities change when evidence changes.

The right partner should make the engagement easier to evaluate over time. That means explicit objectives, clear responsibilities, useful leading indicators, downstream feedback, and decision points that allow the firm to expand, correct, or stop work without relying on narrative alone.
