{"slug":"ad-spend-vs-signed-retainers","title":"Why Programmatic Ad Spend Doesn't Predict Signed Retainers","description":"Mass tort and PI marketing agencies lead with cumulative ad-spend figures — $250M, $500M, $1B+ deployed. The metric makes for great pitch decks and explains almost nothing about whether a specific firm will sign retainers. The math behind why, the five variables ad spend is silent on, and the procurement-grade metrics to demand instead.","url":"https://www.masstortmarketingagency.com/blogs/ad-spend-vs-signed-retainers","published":"2026-05-20","modified":"2026-05-20","author":{"name":"Tarun","role":"Founder, Mass Tort Marketing Agency"},"keywords":["ad spend vs signed retainers","cost per signed retainer","mass tort marketing metrics","plaintiff acquisition procurement","MVA lead vendor vetting","state-specific CPSR"],"blocks":[{"type":"quote","text":"**Quick answer.** Run the category's own headline math: $250M deployed ÷ 2M leads generated = $125 average cost per lead.
