Generative Engine Optimization, explained
Generative Engine Optimization (GEO) is the practice of making your brand visible in AI-powered search engines. When someone asks ChatGPT "what's the best project management tool" or searches Perplexity for "top CRM software," AI engines synthesize answers from across the web 鈥?and GEO ensures your brand is among the sources they cite.
Unlike traditional SEO, which focuses on ranking in blue links, GEO is about influencing how large language models describe and recommend your brand. Brand mentions correlate 3x more strongly with AI visibility than backlinks (Ahrefs study of 75,000 brands). The tools to monitor this are evolving fast 鈥?and we track them all.
