TL;DR: The buzz around AIO, GEO, and AEO sounds exciting, but most of it is just old SEO dressed up in new acronyms. Google’s been powered by AI, NLP, and machine learning since RankBrain and BERT. While generative search, LLMs, and AI Overviews change traffic patterns, they don’t redefine the fundamentals. It’s still about search, intent, structure, and authority — the same game, just another layer to master.
This article started as part of a short Q&A with Igor Buyseech (orig. Igor Bajsić), a warm-up before the upcoming Chiang Mai SEO Conference, where both Igor and I will be speaking. Igor asked:
“What’s your take on the whole AIO/GEO/AEO movement? Do you consider it beyond SEO?”
It’s a fair question — and one that perfectly captures the current industry mood. Everyone’s talking about AI-powered search, new models, “answer engines,” and the supposed end of SEO. After years of seeing the field reinvented, rebranded, and “killed” in headlines, I can’t help but smile.
So let’s take a closer look at these acronyms — and why they’re not new paradigms but just new packaging for what SEO already does (and still does better than ever).

When new acronyms help (and when they don’t)
There’s nothing wrong with introducing new terms — as long as they clarify communication. Otherwise they would be just buzzwords (and often they become ones). For example, technical SEO has a shared definition: crawling, indexing, rendering, site architecture, speed, and structured data. It’s a useful label because it builds consensus.
The problem starts when new labels like AIO or GEO pop up without clear meaning or methodology. Without consensus, they turn communication into noise instead of knowledge.
They confuse clients, who already find SEO abstract. They confuse learners, who are still trying to understand the fundamentals. And they distract practitioners from the bigger picture: SEO isn’t a narrow tactic — it’s an adaptive system.
When we rename core principles every two years, we don’t move forward; we just fragment understanding.
The illusion of something new
Facebook, Amazon, YouTube, TikTok, LinkedIn — all of them run on search engines. Different platforms, same principle: matching intent to indexed information.
If you know how to optimize for that, you’re doing SEO — Search Engine Optimization. The name still fits.
Remember AltaVista or Yahoo? Those “prehistoric” search engines ran on lexical matching. Then semantic search arrived — focusing on intent, not just strings. It didn’t kill SEO; it evolved it. The same is happening now with AI-powered search.
Every leap in search technology — semantic, entity-based, generative — reinforces SEO’s role, not replaces it. Because the more complex the system, the more it needs structured, optimized, and authoritative data to rely on.
There’s no need to reinvent the acronym wheel every time a new layer appears. The AIO/GEO/AEO trend just rebrands what SEO already does: help machines understand human intent.
AI vs. layers of classical SEO
AI prompting to find answers, products, or inspiration is still search — just expressed differently. Being referenced in ChatGPT, Gemini, Perplexity, Claude or Copilot still depends on three classical SEO layers:
- Technical SEO: correct rendering, crawlability, and data structure that make content accessible and learnable for both search engines and AI retrievers.
- Offsite SEO: backlinks, mentions, co-occurrence, and reputation signals — the connective tissue that LLMs and search algorithms alike use to assess reliability.
- Content + on-page optimization: semantically organized, well-linked content architecture that reduces the cost of retrieval for any search or AI system.
They all overlap and are simplifying terms – but here’s the thing, it’s for clarity and usability, for discussion. Not to sell you a next shiny thing by using buzzwords.
This brings us to that meme I used for my SEO Estonia talk in July 2025:
Here is the full story: https://www.szymonslowik.com/redefining-seo-in-the-new-era-of-traffic-generation-seo-estonia-talk/ (you’ll find slides there too).
If an LLM or search crawler can’t parse, categorize, and relate your content, it simply won’t appear — whether in a SERP, an AI Overview, or an AI chat answer.
This is also where entity SEO and structured data play a key role. Schema markup, consistent NAP data, and contextual relationships between pages help both classical algorithms and LLM retrievers understand meaning.
In other words: the better your site’s semantic foundation, the more visible you are — across both search and AI ecosystems.
Generative AI and the changing shape of search
Let’s be fair — Generative AI and Agentic AI introduce something new. These systems don’t just retrieve answers; they compose them. They can execute multi-step tasks: “plan my trip,” “compare providers,” “write my outline.”
Under the hood, though, they still rely on retrieval-augmented generation (RAG) — a process that retrieves information from indexes or embeddings and blends it with LLM-generated language.
That means:
- the retriever still works like a search engine,
- the generator is just an interface layer, and
- your content still needs to be indexed, relevant, and authoritative to be retrieved in the first place.
Sound familiar? It’s SEO.
This is why AI optimization isn’t something “beyond SEO.” It’s just SEO applied to new retrieval and ranking systems.
It’s still inbound marketing at its core:
- People express intent (queries or prompts).
- Systems match that intent to indexed knowledge (training data, embeddings, and search results).
- The system provides answers that trigger further actions or conversions.
The interface changes — the principle doesn’t.
Google and AI: this isn’t new at all
Every time someone says, “Now Google is using AI,” an SEO somewhere quietly laughs. AI has been embedded in Google Search for over a decade.
Let’s recap the timeline:
- RankBrain (2015) brought machine learning to ranking decisions.
- Neural matching, embeddings, and NLP evolved semantic understanding.
- BERT refined contextual interpretation of queries.
- Passage indexing, Knowledge Graph combined entity-level and behavioral data.
- Add featured snippets, especially direct answers, spice it up with Navboost/Glue systems that help the engine to understand the true users’ intent and confirm satisfaction, and here we are.
These systems laid the foundation for AI Overviews, which use retrieval, context ranking, and natural language generation to synthesize responses.
In other words: RAG didn’t start in 2024. It’s the culmination of everything Google’s been building since RankBrain.
Even behavioral signals like CTR, dwell time, and satisfaction — measured through systems like Navboost — are part of this same learning feedback loop. And Google has been using those for longer than you can say. Pandu Nayak from Google said the click-based system “dates back at least to 2005” as part of his testimony to the DOJ.
So yes, AI Overviews changed traffic patterns, but the principle remains. Google still retrieves, interprets, ranks, and presents information — it just does so more conversationally.
What’s actually changing: user behavior and traffic distribution
AI Overviews and generative systems didn’t erase SEO — they shifted visibility and expectations.
Traffic redistribution isn’t new.
- Mobilegeddon forced mobile-first optimization.
- Featured snippets created zero-click answers.
- Knowledge Graph emphasized entities over pages.
- Now AI Overviews consolidate information into conversational summaries.
The pattern is consistent: every new format favors structured, clear, and authoritative data.
That means the best-performing strategies now blend semantic SEO, entity optimization, user-intent mapping, and link-driven authority.
And yes — link building still matters. It’s not about quantity but about control and curation — selecting referring domains, context, anchors, and relationships in a way that builds a coherent authority signal.
If your name or brand consistently appears in trusted, contextually relevant spaces, both Google’s algorithms and LLMs will “trust” you more.
That’s why offsite SEO and authority control — the theme of my Chiang Mai SEO Conference talk — are more important than ever in the AI era.
It’s still search. It’s still SEO.
Whether it’s traditional search, social discovery, or generative engines — the goal is the same: Help people find relevant, trustworthy answers through systems that interpret intent.
So no, AIO, GEO, or AEO aren’t revolutions. They’re evolutions — natural extensions of SEO principles adapted to new environments.
The more AI integrates with search, the more SEO expertise matters — because machines now depend even more on human-curated, structured, and optimized data. We need to feed the system in some way. Our expertise should help us to excel in getting results for the clients.
Final thoughts: same game, new layer
If you’ve been in this industry long enough, you know the pattern. Every “revolution” in search is really another iteration.
AI reshapes interfaces, diversifies traffic, and challenges content formats — but it doesn’t replace the strategic layer that connects human intent with machine interpretation.
SEO remains the bridge between what people need and how systems find it. And as those systems become smarter, the need for precise, structured, and credible content only grows.
So next time you hear about the “next big thing beyond SEO,” remember: you don’t need a new acronym. You just need to understand the next layer — and control it.
What to do next?
If you already learned about the true nature of SEO, GEO, LLMEO etc. now you know, it’s just a matter of layering concepts that cannot live one without another.

This article is part of my ongoing reflections leading up to my session at Chiang Mai SEO Conference 2025. My talk, “Offsite SEO In The AI Era: Links, Authority & Control Over Chaos,” explores how link building and authority signals remain the key leverage points in a world increasingly mediated by LLMs and AI-driven search.
If you’re attending CMSEO, come say hi — I’d love to continue this conversation about the real future of SEO.
Glossary + FAQ
Structured answered to all your questions:
What is AIO in SEO?
AIO stands for AI Optimization — a term used to describe adapting content and websites for AI-driven search experiences, like ChatGPT, Gemini, or Perplexity. In practice, it overlaps heavily with traditional SEO because AI tools still rely on indexed data, quality content, and strong authority signals.
What does GEO mean in SEO?
GEO, or Generative Engine Optimization, refers to optimizing content for generative search engines — such as Google’s AI Overviews or other answer-generation systems. While the idea sounds fresh, it’s largely an extension of established SEO practices focused on intent, entity relationships, and structured information.
Is AEO (Answer Engine Optimization) really different from SEO?
Not really. AEO focuses on optimizing content to appear in answer boxes, featured snippets, or conversational responses — all of which have existed in Google for years. It’s still SEO, just with a narrower focus on direct answers.
What’s the difference between SEO and AIO/GEO/AEO?
Mostly branding (which is related also to SERM). These acronyms describe slightly different aspects of search and AI evolution, but they don’t redefine the fundamentals. SEO already includes optimizing for visibility, intent, and authority — whether the answer comes from Google, YouTube, or a generative model.
When did Google start using AI in search?
AI has powered Google Search for years. RankBrain (2015) introduced machine learning to ranking. Then came BERT, neural matching, embeddings, and passage indexing. What’s new today are AI Overviews, which change how information is presented — not how ranking fundamentally works. But there are ways to optimize specifically for AI Overview snippet as well.
Do AI Overviews mean SEO is dead?
Not at all. AI Overviews may change how users interact with results and shift traffic patterns, but they don’t replace SEO. They simply reward clearer information architecture, entity-based content, and trustworthy sources — all core principles of SEO.
What is Agentic AI and how does it affect search?
Agentic AI refers to systems that can perform multi-step actions, not just generate text. For example, planning a trip or writing code. While this expands how users find information, it still relies on optimized, structured data — so SEO principles remain relevant.
How should marketers adapt to AI-driven search?
Focus on clarity, authority, and structure. Optimize for entities, context, and user intent. Build strong link profiles and content ecosystems that signal expertise. The tools and outputs evolve, but the fundamentals stay the same.
Is SEO still worth investing in?
Absolutely. As AI systems grow, they depend even more on structured, high-quality information. SEO provides that structure — it’s the foundation of discoverability for both traditional search and generative engines. AI needs grounding, query augmentation and authority signals and this is why SEO is your foundation for AI driven future.
