What problem does it solve? A site can be visible in Perplexity yet invisible in ChatGPT because each AI search platform has different crawlers, source preferences, citation formats, and freshness requirements. This Skill diagnoses platform-specific visibility gaps and produces targeted optimization playbooks instead of generic GEO advice. ## Core Features & Use Cases - Platform Profiles: Documents crawler behavior, source preferences, and required checks for Google AI Overviews, ChatGPT, Perplexity, Gemini, and Bing Copilot. - Cross-Platform Test Matrix: Runs 5-10 target queries (brand, product, category, comparison, pricing) across all platforms and scores visibility 0-100 per platform. - Platform-Specific Playbooks: Provides step-by-step remediation for each platform, such as unblocking PerplexityBot, publishing llms.txt for ChatGPT, or submitting sitemaps to Bing Webmaster Tools. - Use Case: A brand appears in Google AI Overviews but never in Perplexity answers. Run the test matrix, discover PerplexityBot is blocked in robots.txt, unblock it, and rewrite top pages with 134-167 word quotable passages. ## Quick Start Test my brand's visibility across Google AI Overviews, ChatGPT, Perplexity, Gemini, and Bing Copilot using these target queries and produce a platform optimization report.
