LLM search optimization (AEO)
Optimize your content to appear as a cited source in AI-generated answers from ChatGPT, Perplexity, and Google AI Overviews.
Why this can grow a startup
AI search engines like ChatGPT, Perplexity, and Google AI Overviews synthesize answers from multiple sources rather than ranking pages. Fewer than 10% of sources cited by AI engines overlap with top Google organic results, so traditional SEO alone is insufficient. Brands that earn third-party mentions, maintain fresh content (updated quarterly), and structure pages with clear entity data and citations get cited more often. Zero-click searches now account for 60% of all queries, making AI citation the new front door to discovery. B2B SaaS sites saw AI search traffic grow 127% in just three months in late 2025.
Company example
eMarketer reports fewer than 10% of sources cited in ChatGPT, Gemini, and Copilot rank in top 10 Google organic results — meaning traditional SEO won't guarantee AI visibility. Zero-click searches hit 60% in 2025 (77% on mobile). GEO is now a distinct discipline from SEO.

When to use it
Use this when SEO is relevant to 0-100, 100-1K and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
Founder checklist
- Read forbes.com and identify what is directly supported.
- Choose one channel context: SEO.
- Define the test around 10% of sources cited in ChatGPT.
- Set an owner, evidence window, and stop condition before launch.
