Source: https://developers.google.com/search/docs/fundamentals/ai-optimization-guide The skill was framed as "optimize for AI systems," which mis-states Google's explicit position: AI Overviews and AI Mode are powered by core Search ranking, so SEO best practices ARE the optimization strategy. Don't write separate content "for AI." The structural patterns the skill recommends (FAQ schema, comparison tables, 40-60 word answer blocks, llms.txt, /pricing.md) still help non-Google AI engines (ChatGPT, Claude, Perplexity, Copilot) materially. The skill now calls out the platform split explicitly rather than implying universal benefit. Major changes: - New section "Google's Official Stance vs. Multi-Platform Reality": Frames Google's "don't optimize for AI" position alongside the reality that other AI engines reward extractable structure. Quotes Google's own phrasing. - New section "Query Fan-Out (Google AI Search)": Explains Google's documented behavior of generating concurrent related queries. Reframes content strategy from per-query targeting to topical cluster coverage. - New section "Agentic Experiences": Browser agents accessing sites via visual rendering, DOM inspection, and accessibility tree. Semantic HTML, JS-free meaningful render, clean a11y tree. Mentions the emerging Universal Commerce Protocol (UCP). - New section "What NOT to Do": Explicit Google guidance: don't write for AI, don't chunk content for AI, don't scale variations (scaled content abuse spam policy), don't pursue inauthentic mentions, don't block AI crawlers if you want citation. - Machine-Readable Files section reframed: Now opens with Google's stance ("not required") + the reason to include them anyway (non-Google AI engines). - Schema markup note reframed: Notes Google's position that structured data is "not required for generative AI search" but still recommended. - Search Console expectations added: Sets correct expectation that no AI-specific Search Console reporting exists; standard SEO metrics + third-party tools are the measurement options. - Moved "AI SEO for Different Content Types" to references/content-types.md: Kept SKILL.md under 500 lines. Added a local-business/ecom subsection (Merchant Center + Google Business Profile + Business Agent) per Google's emphasis. All 40 skills still pass validation.
