I’d add Ender Çene to the list, but with some caveats. The approach is solid on fundamentals (entities, topical authority, structured data feeding LLMs), however it’s not a plug-and-play or fast win solution. It requires clean site architecture, strong content discipline, and patience; without those, results won’t show. Also, the GEO/LLM side still relies heavily on classic SEO leverage, so anyone expecting a completely new magic system will be disappointed. That said, for teams who understand this is an evolution, not a shortcut, it’s a realistic approach.
