What GEO / AEO practitioners can learn from Eric Siu
- **Third-party mentions are fuel**: an LLM’s world model comes from web-scale text, so consistent mentions on Reddit, media and communities reinforce how AI sees you. - **Create once, distribute everywhere**: reshape core ideas for each platform to widen the surface area that gets crawled and cited. - **Narrative consistency**: keep the same facts and positioning across channels so AI is not left unsure of you.
**GEOly angle**: A growth-marketing operator's take on where SEO meets AI search, packaged for founders and marketers scaling demand.
What it means for brands going global
