Why are there so many AI search acronyms?
Every major change in discovery creates new language. The terms are useful when they clarify an outcome — and confusing when they repackage the same work.
Search engines now generate answers. AI assistants retrieve information from the web. A source may influence an answer without receiving a click. A brand may be cited without being named, or named without its website being cited. Agents can go further and complete tasks.
Four lenses on the same discovery system.
Each acronym is a useful lens. None of them is a separate system.
| Term | Primary focus | Desired outcome | Main limitation |
|---|---|---|---|
| SEO | Discovery and eligibility | Ranking, visibility and visits | Ranking does not guarantee citation |
| AEO | Directly answering questions | Answer inclusion | Often reduced to FAQ formatting |
| GEO | Generated response visibility | Citation, mention, recommendation | Measurement remains variable |
| LLMO | Representation in LLM experiences | Retrieval and brand representation | The definition is inconsistent |
Use the label that helps your team communicate. Measure the outcome the label is meant to improve.
What Google’s 2026 guidance changes.
Google now explicitly recognises AEO and GEO as common terms for AI-search visibility work. From Google Search’s perspective, however, optimisation for generative features remains part of SEO, because those experiences use established ranking and quality systems.[1]
Do the fundamentals well: make valuable information accessible, trustworthy and useful. Do not build a parallel site for an imagined "AI reader".
The guidance rejects several fashionable shortcuts: no special schema is required; Google does not use llms.txt; prescribed content chunking is unnecessary; and rewriting solely for AI systems is not the goal. Unique, current and expert-led content remains central.
Build one outcome funnel.
Organise the work around what the system — and the buyer — must be able to do next.

Bing’s AI Performance reporting reinforces why these stages should be separated: citation data shows visible source use, not rankings, authority, traffic or engagement.[2] Google’s Search Console generative AI reports similarly expose impressions, pages, countries, devices and dates as visibility data — not a complete business outcome.[4]
One strategy. Different platform controls.
The acronyms do not require four independent teams. They require coordinated ownership across the discovery funnel.
Own retrieval
Indexation, internal linking, feeds, structured data and technical eligibility.
Own the answer
Clear claims, original evidence, current facts and useful explanation.
Own recognition
Consistent positioning, expert participation, reviews and independent coverage.
Own the action
Accessible journeys, reliable forms, clear choices and successful task completion.
The transformation matters more than the terminology. Optimise the connected journey from retrieval to action.
