GSO (Global Search Optimization) is a global optimization approach covering all search surfaces: classic SEO (Google, Bing), AEO (featured snippets, AI Overviews), GEO (ChatGPT, Perplexity, Claude) and specialized platforms (YouTube, Amazon, etc.).
GSO is an umbrella term covering all forms of search optimization. GEO is a specific component, focused on generative AI engines. At PingPrime, we focus on GEO because that's where the biggest paradigm shift and the greatest opportunity for brands lies in 2026. SEO remains the foundation, but GEO is the new differentiator.
