When generative AI describes your company, what appears in the answer as citations is neither the corporate website that communications teams control most tightly, nor the news coverage they have worked hardest to earn. It is a far wider set of sources that contains both — and whose composition differs from one AI service to another.
In Japan, generative AI adoption inside corporate communications departments rose from 37.2% (2024) to 77.0% (2025) across two surveys by the Study Group on Generative AI in Public Relations at the Japan Society for Corporate Communication Studies (121 and 104 valid responses). The uses reported, however, are concentrated in producing, summarizing, and supporting planning.
The supply structure, meanwhile, does not match the assumptions communications work has been built on. McKinsey's analysis estimates that a brand's own website typically accounts for around 5–10% of the sources AI search draws on (a reference figure, as the calculation method is not disclosed). And of the URLs cited in AI Overviews, 37.9% were within the first 10 SERP blocks for the same query (Ahrefs; 863,000 SERPs and 4 million AI Overviews URLs). The cast of cited sources also differed substantially between services within the datasets examined.
Then, in May 2026, AMEC — the international body for communication measurement and evaluation — published the AMEC GEO Principles. This article maps that supply structure from a PR and communications perspective and checks it against AMEC's principles. It is not about responding to errors; it is about where accurate information is drawn from, and how it is handled, in normal times.
The observation scope of this article (important)
What this article treats as measurable is the citation links and supporting links displayed in an AI answer. These are publicly visible clues to what an answer rests on. They are not the full set of sources the model consulted or weighed internally, nor do they show the causal contribution of any individual page. Google uses the term "supporting links" for these in its own official documentation.
AMEC's GEO Principles take the same position: observed AI outputs are directional indicators, to be validated transparently across tools, prompts, markets, languages, and time. The question in this article's title — what AI cites — should be read under that limitation.
Who this is for
Communications and PR departments at operating companies, PR agencies, and heads of corporate communications. Recruitment communications are out of scope (see Candidates research your company with AI).
A note on terminology
This article treats labels such as AIO, GEO, and LLMO as practitioner terms rather than official standards. Google Search states in its official documentation that no additional requirements and no special optimization are needed to appear in generative AI features, and that optimizing for generative AI search is optimizing for the search experience — which is still SEO. For the terms themselves, see What AIO is and What LLMO is.
"AIPM (AI Perception Management)," used in the second half of this article, is likewise not an industry-standard term; it is how Vaipm frames this area. It stands on the same footing as AIO, GEO, and LLMO.
