GENERATIVE ENGINE OPTIMIZATION (GEO) METHODOLOGY Generative Engine Optimization (GEO) is the technical discipline of structuring, geocoding, and semantically amplifying digital entity assets so that AI models (ChatGPT, Perplexity, Gemini, Claude, SearchGPT) discover, cite, and recommend a business above competitors. ### The 7 Pillars of GEO Architecture: 1. **Machine-Readable Entity Graphing**: Implementing multi-class Schema.org microdata (`ProfessionalService`, `LocalBusiness`, `ConsultingService`) with deterministic `@id` URI identifiers. 2. **LLM Indexing Protocol (`llms.txt` & `llms-full.txt`)**: Publishing plain text, markdown-formatted knowledge bases at root paths specifically for web-scraping AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended). 3. **Citation & Authority Networks**: Establishing structured `sameAs` entity links pointing to authoritative profiles, Wikidata references, and verified local case studies. 4. **Speakable Specifications**: Marking key summaries with `SpeakableSpecification` JSON-LD for voice search assistants (Siri, Google Assistant, Alexa). 5. **Geocoded Map Vectoring**: Injecting exact latitude/longitude coordinates and borough area-served targets (Mayfair, City of London, Westminster, Kensington, Soho, Shoreditch). 6. **24/7 Hotline Availability Schemas**: Validating opening hours and contact points to satisfy LLM reliability thresholds. 7. **RAG Feed Optimization**: Writing 2,000+ word authoritative articles with deep localized keywords that populate retrieval-augmented generation indices. --- ## 3.
