Optimizing for AI Search (GEO & LLMO): Ranking in ChatGPT & Claude

By Search & Semantic Intelligence Team · 6 min read

Users are increasingly bypassing traditional Google search results in favour of direct conversational synthesis in Perplexity, ChatGPT Search, and Claude Artifacts. If your brand is not indexed in their semantic knowledge graphs, you simply do not exist.

The Mechanics of Generative Engine Optimization

Generative search engines evaluate web pages using retrieval-augmented generation (RAG) rather than PageRank link equity. To win citations, sites must align with 3 pillars:

  • Entity Clarity: Use unambiguous JSON-LD schema linking your organization to Wikidata, Crunchbase, and government entity registries.
  • Fact Density: LLMs extract high-density tables, direct statistics, and clear definitions over long fluffy introductions.
  • Crawl Accessibility: Ensure your robots.txt allows GPTBot, PerplexityBot, and ClaudeBot to scrape clean semantic HTML without client-side rendering hurdles.
