Observation coverage. Two missing answers reduce coverage; they are not negative brand answers.
SEO & AI visibility
SEO improves search discovery. AEO focuses on useful direct answers. GEO focuses on visibility and representation in generated answers. AIO is used more broadly for AI optimisation; some people also use it for AI Overviews, so always name the actual surface. These labels overlap. They do not require four copies of the same page.
| Term | The question | Evidence to inspect |
|---|---|---|
| SEO · Search engine optimisation | Can the right searcher discover a useful page? | Crawl access and page evidence; actual indexing, queries, impressions and clicks from the relevant search account. |
| AEO · Answer engine optimisation | Does the page answer the user's question clearly? | Visible answers, context, semantics and applicable structured data. Readiness does not prove an answer was displayed. |
| GEO · Generative engine optimisation | Does a recorded AI answer mention, cite or recommend the business accurately? | The original answer, prompt, provider, interface, model when known, market, sources and collection time. |
| AIO · AI optimisation | Which AI-mediated discovery or task are we improving? | Name the actual product and measurement surface. Write “Google AI Overviews” in full when that is what you mean. |
Illustrative calculation, not a customer result: you plan 10 AI runs, receive 8 usable answers, find 2 brand mentions and 1 explicit recommendation.
Observation coverage. Two missing answers reduce coverage; they are not negative brand answers.
Brand presence among observed answers. A mention is not automatically a recommendation.
Overall recommendation coverage. The conditional 1 / 2 rate is 50%, but reporting only that would hide the wider gap.
This small illustration cannot establish a market share or a durable improvement. Preserve counts, collection failures and a consistent panel when comparing periods. If no answers were observed, the rate is not measurable; it is not zero.
Google's current guidance builds generative Search visibility on SEO foundations: useful original content, accessible pages and appropriate technical eligibility. It also documents a Search Console inclusion setting and a Generative AI Performance report. Confirm the actual property and report availability. Native impression data is separate from your own sampled AI answers and cannot be relabelled as recommendations or revenue.
Google does not require llms.txt, special AI markup, tiny text chunks or a separate page for every query variation. Useful content and truthful structured data still need a real audience purpose.
If a public page cannot be retrieved, investigate access first. If the page works but a useful answer is missing, improve that existing resource. If the business is cited without being recommended, inspect what the answer actually says rather than assuming a citation means a sale. If the evidence does not justify an edit, keep the page and gather the missing data.
