What we measured
Between August 4–5, 2026, Mass Tort Ad Agency measured the homepage of every personal injury law firm in the BrandTerritory index that operates a working website — 627 firms across 205 U.S. markets — using the public engine at seo.mtaa.ai under one published weighting: GEO 35%, content 25%, technical 20%, schema 15%, on-page 5%. The same engine, weights, and method used in our August 2026 audit of 18 legal SEO agencies.

The failure is trust, not plumbing
Every high-severity finding was classified into a fixed ten-theme taxonomy, with passing and unmeasurable checks excluded and results spot-verified against live pages. Two failures are near-universal: 98% of firms make claims a machine cannot verify — superlatives and verdict figures with no case, court, date, or source — and 74% publish legal content with no named, credentialed attorney attached. An answer engine that cannot verify a claim will not repeat it, so the firm's chosen differentiator is precisely what gets dropped from every AI answer.


How the study checked itself
A 1-in-4 systematic sample (158 firms, measured twice each; pass-to-pass repeatability 1.53 points mean absolute difference) predicted a market mean of 69.0 (95% CI 68.0–69.9). The number was bad enough that we ran the full census rather than publish an estimate. The census answered 69.4. Three errors were caught by our own verification chain before publication — a keyword-based taxonomy replaced by model classification, an extraction bug that counted unmeasurable checks as failures, and a mis-attribution during live-site hand-verification — and all three corrections are documented in the report.
