The Background
A Strong Local Firm Ready for a Bigger Market
A personal injury firm based in Myrtle Beach, South Carolina — covering car accidents, truck accidents, catastrophic injuries, and wrongful death across the Grand Strand and surrounding coastal markets. The firm had deep roots in the community and a strong local reputation built over years of practice.
When LawSHIFT began the engagement, the firm was starting from a 14% AI visibility baseline — present in some responses, but inconsistently, and only locally. Seven of their tracked prompts showed zero visibility. South Carolina statewide queries — the ones that reach clients anywhere in the state — were completely out of reach.
The Challenge
Local Visibility, Statewide Ceiling
An Inconsistent Starting Point
At 14% baseline visibility, the firm was appearing in AI responses — but inconsistently. Seven tracked prompts showed zero mentions. The presence that existed was fragile, not systematically built, and could disappear at the next AI model update.
Competitors Owned Statewide
South Carolina statewide PI queries — 'best car accident law firm in South Carolina for serious injury' — were dominated by firms in Columbia and Charleston. A Myrtle Beach firm showing up in statewide results required a fundamentally different kind of authority signal than local queries.
The 100% SOV Opportunity
Myrtle Beach's PI market is competitive but not saturated at the AI layer. The firm that built comprehensive, systematic AI authority first would lock the market. The window for that was open — but not indefinitely.
The Solution
SignalStack 200™ — Local Dominance, Statewide Expansion
LawSHIFT deployed the SignalStack 200™ authority architecture with a two-phase strategy: first establish complete local dominance in the Myrtle Beach market, then expand authority signals to earn rankings on South Carolina statewide queries.
The local phase targeted every relevant Myrtle Beach PI prompt — car accidents, truck accidents, catastrophic injuries, and wrongful death — with systematic authority signals across all five pillars. The statewide phase introduced purpose-built content and citation infrastructure designed to rank in AI responses for queries that reach injury victims anywhere in South Carolina.
Within four months: 100% Share of Voice in Myrtle Beach. Three new statewide SC prompts unlocked.
