Marketing teams are adjusting how they compete for visibility as a growing share of search happens inside AI answer engines rather than traditional results pages. An EMARKETER forecast projects that 31.3 percent of the U.S. population will use generative AI search in 2026, prompting brands to prepare content for platforms such as ChatGPT, Google AI Overviews, and Perplexity alongside conventional search engines.
Two related disciplines have emerged to address the shift. Generative engine optimization, or GEO, focuses on structuring content so AI platforms cite or recommend a brand when users ask questions. Answer engine optimization, or AEO, structures content so it gets extracted and surfaced as a direct answer inside AI interfaces. The two overlap heavily and are often pursued together.
Usage data underlines why the change matters. ChatGPT surpassed 900 million weekly active users by March 2026, and Google AI Overviews now appear in more than a quarter of all searches. Referral traffic arriving from AI tools has shown higher conversion in some measurements, a pattern that has drawn marketer attention to the channel.
Adoption is uneven by company size. Most enterprise marketing teams have started a GEO initiative, while many smaller businesses have not yet begun, a gap that leaves room for early movers among mid-market and local brands. Analysts caution that measurement remains immature, since AI platforms rarely disclose why a given source is cited, which complicates efforts to attribute results to specific optimization tactics.
