Super GEO Agent Readiness

A Claude Skill that covers Generative Engine Optimization (GEO) and agent readiness in one place. SEO targeted blue links. This skill targets the answers AI engines produce, and the agents that fetch and act on your content.

Latest update

Integrated 14 Ahrefs studies published between October 2025 and May 2026 (roughly 1 billion data points across ChatGPT, Google AI Overviews, and AI Mode) into a new evidence base at references/ahrefs-2026-studies.md, with the findings threaded through the content, platform, structured-data, measurement, and audit references.

Three findings reorder the playbook:

1. Schema markup does not move AI citations. A controlled difference-in-differences study of 1,885 pages found no meaningful citation lift on any platform (AI Overviews -4.6%, AI Mode +2.4%, ChatGPT +2.2%, with the last two indistinguishable from zero). The naive 3x correlation between schema and citation turned out to be selection, not cause. Schema is now framed as hygiene for rich results and entity clarity, not as an AI-citation lever, and the audit was recalibrated to match (schema severity dropped from High to Medium).
2. Off-site signals dominate. Across 75,000 brands, YouTube mentions were the strongest correlate of AI visibility (~0.737), ahead of every conventional SEO metric, with off-site brand mentions close behind (0.66 to 0.71). Site page count barely correlated (~0.194). The skill now treats video and earned mentions as the highest-leverage work, with a new off-site presence check added to the audit.
3. "Best X" lists are the most-cited format. Comparison lists made up 43.8% of cited page types across assistants, and a high placement on credible third-party lists correlated with being recommended. The format wins when executed as a primary source, not as thin affiliate filler.

Other updates in this pass: a retrieval-gate section (ChatGPT cites only about half the URLs it retrieves, deciding from the title, snippet, and URL before it opens a page), refreshed Google AI Overview behavior (citations now 38% from the top 10, down from 76% a year earlier; 99.9% on informational queries; clicks to the top result down 58%), the finding that AI Overviews and AI Mode agree 86% of the time but share only 13.7% of their citations (so track them separately), and current market sizing (ChatGPT at ~12% of Google's search volume, while Google still sends ~190x more website traffic and 96.98% of clicks stay in the top 10).

These are single-vendor studies and mostly correlational. Verify against a second source before quoting any figure in client-facing work.

What it covers

Four optimization surfaces, one routing layer:

• Content. Authority, quotability, comprehensiveness, structure, primary-source signaling, and the retrieval gate. The patterns that get a page cited by ChatGPT, Perplexity, Claude, and Google AI Overviews, plus the off-site presence (video, earned mentions, third-party lists) that the data shows matters most.
• Technical site. FAST framework, Schema.org JSON-LD, robots.txt for AI crawlers, llms.txt and llms-full.txt at small-site, large-site, and per-directory scales.
• Platform tactics. Per-engine optimization for ChatGPT, Perplexity, Google AI Overviews, AI Mode, Claude, Gemini, Copilot, and Grok, with current traffic-share and citation-behavior numbers so you know where to spend effort.
• Agent readiness. MCP Server Cards, A2A Agent Cards, OpenAPI, API Catalog (RFC 9727), OAuth metadata (RFC 8414/9728), Web Bot Auth, x402, ACP, UCP, Markdown content negotiation. Compiled from Cloudflare's agent-readiness work and the agentready.org open specification.

Per-engine calibration: policy vs engineering

Google publishes its own AI optimization guide and classifies several common GEO tactics as "myths" for Google AI features. The skill treats Google's guide as a policy document, not as engineering reality. Concrete signals undercut the "myths" framing: Google's own Lighthouse tool checks for llms.txt, two senior Googlers (John Mueller and Addy Osmani) have publicly given opposite advice on markdown pages, Anthropic's published Claude system prompt contains explicit source-quality filters that target SEO-pattern content, and modern retrieval architecture operates on chunks regardless of what the policy document says.

One item on that myths list has since been confirmed by controlled evidence: schema added for AI. The difference-in-differences study above found no AI-citation lift from JSON-LD, so on schema the skill sides with Google and keeps markup for rich results and entity clarity. The llms.txt and chunking items remain contested. Calibrate item by item rather than treating the whole list as right or wrong.

Operational conclusion: for Google AI Overviews and AI Mode, classic SEO at peak quality is the foundation. For ChatGPT, Perplexity, Claude, and training corpora, the additional surfaces in this skill apply. See references/content-strategy.md for the three-layer arbitration model (latent knowledge / active retrieval / arbitration) that explains the mechanism.

When Claude triggers it

Any of these signals fire the skill: GEO, AEO, LLMO, AI SEO, "rank in ChatGPT", "show up in Perplexity", "appear in AI Overviews", llms.txt, agent readiness, MCP server discovery, Web Bot Auth, OAuth for agents, x402, or asking Claude to audit a site for AI visibility.
