The Yardstick Broke
You ranked first for a query last quarter. That does not guarantee that an AI answer will mention your brand when someone asks a related question. Search rankings and generated answers are different experiences, and neither alone captures every way a buyer discovers information.
The shift is worth measuring, but it is easy to overstate. Search engines, chatbots, and other answer tools change over time, and their responses can vary by product, query, and context. The practical task is to understand where your audience looks for information and test whether your brand is visible there.
What Is SEO Now? A Working Definition
Generative Engine Optimization (GEO) is a term used for efforts to make information more discoverable and usable in generative AI experiences. It overlaps with established SEO practices, such as publishing helpful content and making pages accessible to search systems, but it is not a standardized discipline with one agreed definition or set of ranking factors. A 2023 research paper introduced GEO as a framework for improving visibility in generative engine responses; its findings should be read in the context of the systems and experiments studied, not as a universal formula. (sourceRefs: Aggarwal et al., “GEO: Generative Engine Optimization,” 2023)
Traditional search results and generated answers are not interchangeable. Google describes AI Overviews and AI Mode as features that may show links to supporting web pages, while OpenAI says ChatGPT search responses can include links to sources. Those descriptions do not establish that all products use the same retrieval process, or that every answer is based on the same sources. (sourceRefs: Google Search Central, “AI features and your website”; sourceRefs: OpenAI Help Center, “ChatGPT search”)
Measure Visibility, Not a Made-Up Universal Share
There is no single, independently established “share of model” metric that applies across all AI products and queries. A team can define its own measurement: for a specified set of prompts, products, and dates, record how often the brand appears, whether it is recommended, and which sources are cited. Report the method and sample alongside the result; do not treat a small prompt set as a market-wide measure.
A useful measurement plan separates observed outcomes from interpretation:
- Mention rate: In a defined prompt set, how often does the brand appear in the response?
- Citation inclusion: When the product provides sources, how often does it link to the brand’s pages or other relevant sources?
- Recommendation context: Is the brand presented positively, neutrally, or negatively, and in what context? Use a consistent coding method and preserve examples for review.
- Referral and conversion measurement: Where analytics tools identify traffic from an AI product, track those visits separately when feasible. Attribution may be incomplete, and observed conversion differences do not by themselves show that the referral source caused the difference.
These are proposed operational measures, not standardized industry KPIs. Treat changes as signals to investigate, not proof that a particular optimization caused an outcome.
How AI Search Can Differ
Some search and answer products retrieve web pages and show citations; others may also use information learned during model training. The details vary by product and can change. For example, Google documents that its AI search features rely on its existing Search systems and may display links to supporting pages. That documentation does not justify the broader claim that every generative model continuously ingests the whole web, uses the same sources, or weighs mentions in a predictable way. (sourceRefs: Google Search Central, “AI features and your website”)
A brand’s presence on third-party sites may matter when those sites are surfaced or cited, but there is no basis for assuming that any particular forum, directory, or encyclopedia always influences an answer. Check the sources shown in the products and queries relevant to your audience. Keep factual business information consistent, maintain useful pages, and address inaccurate public information where you can.
The Surface Is Fragmenting
People can encounter AI-generated answers in multiple products and interfaces, including search features and standalone chat tools. Product availability, functionality, and usage change over time. Avoid comparing headline user counts unless the figures use comparable definitions, periods, and methods; a monthly figure for one service is not directly comparable to a weekly figure for another.
Likewise, a reported increase in AI-referred visits or sales in one dataset should not be presented as a general conversion lift or a market-wide trend without the underlying source, timeframe, and methodology. Track your own results with clear definitions and note the limitations of referral attribution.
What You Control
You cannot directly set the behavior or ranking logic of an external AI product. You can make your own information accurate, accessible, and clear; maintain consistent descriptions of your organization; and monitor when and how your material appears in the products your audience uses.
Crawler access is not one universal switch. Google documents controls such as Googlebot for Search crawling and Google-Extended for certain uses of content in Google’s generative AI systems. Other providers have their own crawlers and policies. Review each provider’s current documentation before changing robots rules: blocking a crawler can affect access for the specific service, but it does not establish what that service learned from other sources or previously accessed content. (sourceRefs: Google Search Central, “Overview of Google crawlers”; sourceRefs: Google Search Central, “Google-Extended”)
GEO can be a useful label for this work, but claims about how many marketing leaders have adopted it, how much it improves conversions, or how often AI systems recommend a brand require specific, dated evidence. Without that evidence, treat such figures as unverified rather than as benchmarks.
Winning visibility is not simply a matter of chasing rankings or trying to reverse-engineer a model. Publish useful, accurate information, make it accessible, and measure what happens in a defined set of products and queries. Distinguish what you observed from what you infer—and update the strategy as the systems change.
