Look for an agency that has specific experience with LSAs for law firms, not just general PPC experience. Legal marketing has different compliance, lead-quality, and client acquisition considerations, so industry experience matters.
A good agency should be able to handle LSA setup and verification, profile optimization, budget management, lead disputes, and ongoing performance tracking. More importantly, they should track what happens after the lead comes in, including qualified consultations and signed cases.
Before hiring one, ask about their experience with your practice area, how they measure results, what access they need to your account, and how often they report performance.
The right agency should be able to show you how its LSA work connects to actual case opportunities, not just impressions and lead counts.
