Why This Comparison Exists
Houston legal is one of the highest-stakes advertising markets in the United States. Mass tort and personal injury firms spend eight- and sometimes nine-figure annual media budgets. TV, radio, billboards and Google Ads are saturated. Yet a growing share of clients in 2026 — especially in mass tort recruitment and complex injury matters — start with ChatGPT, Perplexity or Gemini. Those surfaces deliver one or two named firms per query, not a page of ads. If your firm is not in that answer, the lead is not yours.
The agencies below do strong work in traditional digital. None has yet productised AEO. That is where we come in.

Why AEO Is The Missing Layer For Houston Legal
Houston mass tort specifically has a client-acquisition profile that rewards AEO more than almost any vertical. A claimant researching a potential Camp Lejeune or PFAS or paraquat matter is reading forums, asking LLMs about symptoms and eligibility, and then asking directly "which lawyers handle these cases in Houston". The LLMs currently cite a mix of national aggregators, directories and a handful of firm domains. The firm domains that get cited are the ones publishing extraction-grade content on the relevant matter — entity-dense, schema-rich, authoritative and specific.
Personal injury and general litigation work similarly. The queries are narrower (auto, 18-wheeler, maritime, refinery, construction) but the dynamic is identical. None of the five agencies above is currently productising this work.
