【2026年最新】AI Marketing Mix Modeling(MMM)完全ガイド｜Recast/Lifesight/Meta Robyn/Nielsen MTA徹底比較

<h2>AI Marketing Mix Modeling市場規模と2026年トレンド</h2> <p>Marketing Mix Modeling(MMM)市場はCookie廃止・iOS ATT・GDPR/CCPA規制でMTA(Multi-Touch Attribution)からMMMへ回帰、2024年$3B→2030年$10B(年率22%)に再加速。Forrester Marketing Measurement調査ではFortune 500 CMOの68%が「MMM導入済or導入予定」、平均Marketing ROI+25%・Budget Reallocation Efficiency+40%・Channel Mix Optimization+15%が報告されています。AI MMMはBayesian MMM(階層モデル・Prior知識活用)・Saturation Curve(Channel飽和点)・Adstock Decay(広告残存効果)・Geo-Lift Test(地理実験・Causal Inference)・Incrementality Test(Holdout)・Scenario Planning(Budget Reallocation)・Daily/Weekly Refresh(従来Quarterly→Daily)・Privacy-Safe(Cookie/IDFA不要)を統合実現します。</p>
