GEO: AI visibility as a discipline of its own
Search is changing: people increasingly ask their questions to ChatGPT, Perplexity, Gemini and Google's AI Overviews. GEO (Generative Engine Optimization) makes sure your brand is mentioned, cited and recommended in these AI answers. At Semtrix, GEO is not a subcategory of SEO but a fully-fledged discipline in its own right – with its own methods and a dedicated GEO/LLM tracking tool that makes AI visibility measurable.
We took GEO seriously before it became an industry trend.
