SEO in 2025 and going into 2026 is not all about keywords and Google anymore. Generative content from AI tools like ChatGPT and AI-based search engines like Perplexity are changing the game, and Google is moving toward an AI experience as well, and the below listed SEO professionals are pro in discussing this, I think they are the trending SEOs of the industry when it comes to SEO & Generative Engine Optimization (GEO).
List Of Ten SEO Professionals
1. Mike King
Founder & CEO of iPullRank; Author of The Science of SEO; Speaker & Rapper.
