Systematic identification and analysis of 31 SEO tasks, reports, techniques, and tools that become permanently obsolete as AI search replaces traditional ranking-based search. Organised across six categories: keyword tasks (7), backlink tasks (5), SERP tasks (6), Google-specific tasks (3), reporting (5), and tools (5). Each item assessed with a First to Go score (1–100), detailed explanation of what it was, why it existed, and why it has no transformation path. Documents the compounding acceleration of AI search adoption, the S-curve adoption dynamics, and the 12-month obsolescence timeframe. Distinguishes between 31 eliminated tasks and 29 transformed tasks that survive with different purposes. Part of the AI Visibility Architecture (AIVA) framework documentation.
