暫定日本語訳:GEO, AEO, と SEO share その same foundation — quality コンテンツ, authority, technical eligibility — but differ in one structural inversion: unlinked brと mentions (0,664 correlation) outper向けm backlinks (0,326 DR) 向け AI visibility, その opposite of traditional SEO.

暫定日本語案: Google explicitly frames AI-feature eligibility through existing Search requirements raそのr than a new technical discipline. Evidence for this claim Google says established SEO fundamentals continue to apply to AI Overviews and AI Mode, without additional technical requirements. Scope: Google Search AI features; not a statement about every generative or answer engine. Confidence: high · Verified: Google: AI features and your website The original GEO paper measured generative-answer visibility under its own benchmark, so its tactics should not be treated as permanent plat向けm rules. Evidence for this claim GEO was formalized in a 2023 research paper that measured source visibility within generative-engine responses. Scope: Origin and experimental framing of GEO; subsequent marketing uses of the term vary. Confidence: high · Verified: Aggarwal et al.: GEO paper

暫定日本語案: TL;DR — GEO, AEO, と SEO sit on その same foundation: quality コンテンツ, 暫定日本語案: authority, E-E-A-T, と technical eligibility — と AI search runs RAG over その 暫定日本語案: same web indexes traditional search uses, so most SEO carries over 向け free. 暫定日本語案: Google と Bing both frame AI optimization as “still SEO.” The genuinely 暫定日本語案: different part is one structural inversion: in Ahrefs’ 75 000-brと correlation 暫定日本語案: study, brとed web mentions correlate 暫定日本語案: 0,664 とともに AI Overview brと visibility versus Domain Rating’s 0,326 — unlinked 暫定日本語案: mentions, near-worthless in classic SEO, are その strongest AI signal. Everything 暫定日本語案: else that’s “different” (citation vs. rank as その metric, passage-level 暫定日本語案: retrieval, rank-5 beating rank-1, keyword stuffing hurting, 23x conversion at 暫定日本語案: 190x less traffic) follows from how AI answers are assembled. Caveat: その 暫定日本語案: correlation is descriptive, not causal, と none of そのse labels guarantee 暫定日本語案: ranking, citation, traffic, or conversion lift. Priority: do SEO, そのn layer その 暫定日本語案: AI signals on top.

暫定日本語案: First, その definitions that matter

暫定日本語案: None of そのse three labels are stとardized その way SEO is. SEO carries decades 暫定日本語案: of shared search-industry usage; GEO と AEO definitions vary by author, product, 暫定日本語案: surface, と date — treat any GEO/AEO claim (including mine) as scoped to whoever 暫定日本語案: is using その term, not an industry consensus.

暫定日本語案: Three acronyms, one job, three vantage points:

  • 暫定日本語案: SEO wins ranked link placement 向け a URL.
  • 暫定日本語案: AEO makes you be その answer — その engine extracts your text 向け a featured 暫定日本語案: snippet, a voice reply, or an AI answer. Coined by Jason Barnard in a January 暫定日本語案: 2018 Trustpilot white paper, originally a voice-search と featured-snippet 暫定日本語案: idea, そのn revived 向け その LLM era.
  • 暫定日本語案: GEO gets you cited as a source inside a synそのsized AI response. Coined 暫定日本語案: academically by Aggarwal et al. (KDD 2024).

暫定日本語案: The pedagogically useful split is you ARE その answer (AEO) vs. you’re CITED 暫定日本語案: in その answer (GEO) — distinct origins, but その 2025–26 tactics overlap ~90%, so 暫定日本語案: I’ll mostly treat GEO/AEO as one thing against SEO below.

暫定日本語案: What’s その same across all three

暫定日本語案: This is most of その surface area, と it’s why I keep calling this evolution, not 暫定日本語案: revolution.

  • 暫定日本語案: Quality コンテンツ is その foundation. The same helpful, people-first コンテンツ 暫定日本語案: that ranks also gets cited.
  • 暫定日本語案: Authority still matters — it’s just measured differently (next section). The 暫定日本語案: concept “trusted sources win” is unchanged.
  • 暫定日本語案: Technical eligibility is a shared gate. A ページ that can’t be crawled と 暫定日本語案: indexed can’t be cited. Crawlability, indexability, HTTPS, と structure are 暫定日本語案: prerequisites 向け both.
  • 暫定日本語案: AI search reads その same indexes. Google AI Overviews, ChatGPT Search, Bing 暫定日本語案: Copilot, と Perplexity ground answers とともに retrieval-augmented generation 暫定日本語案: (RAG) — pulling from その same web indexes traditional search uses. Microsoft 暫定日本語案: says it outright: getting cited “comes down to two things: first, make sure Bing 暫定日本語案: has indexed your コンテンツ so it appears in result sets, と second, make sure your 暫定日本語案: コンテンツ is clear, structured, と trustworthy enough to win その citation.”

暫定日本語案: What’s genuinely different — その signal inversion

暫定日本語案: If you remember one thing, remember this. In Ahrefs’ 75 000-brと correlation 暫定日本語案: study by Louise Linehan と Xibeijia Guan, 暫定日本語案: which I presented と interpreted at Ahrefs Evolve 2025, 暫定日本語案: その signals predicting Google AI Overview inclusion line up like this:

| 暫定日本語案: Signal | Correlation とともに AI Overview inclusion | | 暫定日本語案: --- | --- | | 暫定日本語案: Brとed web mentions | 0,664 | | 暫定日本語案: Brとed anchor text | 0,527 | | 暫定日本語案: Brとed search volume | 0,392 | | 暫定日本語案: Domain Rating | 0,326 |

暫定日本語案: Read that top-to-bottom: unlinked brと mentions — which pass no ページRank と 暫定日本語案: contribute almost nothing in traditional SEO — are その single strongest predictor, 暫定日本語案: と そのy beat Domain Rating, その classic link-based authority proxy. That is a 暫定日本語案: structural inversion, not a marginal difference. It means PR, social, と 暫定日本語案: brと-構築ing teams now own a direct AI-visibility lever, not just an indirect one. 暫定日本語案: My one-line framing of その whole shift: “From ‘Optimize Your Site’ → ‘Optimize How 暫定日本語案: The Internet Talks About You’.”

暫定日本語案: That table is a dated correlation from one dataset, not a causal test. It doesn’t 暫定日本語案: control 向け confounders — an established brと may earn both more mentions と 暫定日本語案: more AI Overview inclusion because it’s simply bigger と better-known, not 暫定日本語案: because その mentions caused その inclusion — と no controlled experiment here 暫定日本語案: isolates wheそのr adding mentions moves inclusion 向け a given site. Read it as a 暫定日本語案: descriptive predictor worth tracking, not a guaranteed lever.

暫定日本語案: The oそのr differences (そのy follow from how answers are built)

暫定日本語案: These are real, but そのy’re downstream of “an AI assembles an answer from passages” 暫定日本語案: raそのr than “a SERP ranks URLs”:

  • 暫定日本語案: Citation, not rank, is その success metric. SEO gives you a position number 暫定日本語案: (average position 2,3). AI search gives you cited / not-cited — と even that is 暫定日本語案: hard to measure consistently. There’s no “outranking” anyone; you’re in その 暫定日本語案: citation set or you’re not.
  • 暫定日本語案: Passage-level retrieval, not URL-level ranking. AI systems extract specific 暫定日本語案: passages と can synそのsize across several ページ. So a rank-5 ページ can be cited 暫定日本語案: over その rank-1 ページ if it has その better paragraph 向け その sub-question — which 暫定日本語案: is structurally impossible in a traditional SERP. The Princeton GEO paper found 暫定日本語案: rank-5 ページ gained +115,1% in citation frequency from GEO tactics, while その 暫定日本語案: rank-1 ページ actually lost ~30,3%.
  • 暫定日本語案: Keyword stuffing inverts. The same GEO paper measured keyword stuffing at 暫定日本語案: -9% 向け AI citation. In limited exact-match SEO cases it can still scrape a 暫定日本語案: marginal benefit; in AI answers it degrades fluency と hurts you.
  • 暫定日本語案: A different traffic profile. AI search sends far less traffic — in my 暫定日本語案: analysis of 76 000 sites, Google sent 暫定日本語案: roughly 190x more Webサイト traffic than ChatGPT, と ChatGPT’s estimated click-through rate was about 暫定日本語案: 96% lower than Google’s (1,3% vs. 29,2%). But that trickle converts: in my 暫定日本語案: analysis of Ahrefs’ June 2025 internal data, I found AI search visitors converted at about 23x その rate of traditional 暫定日本語案: organic search 向け Ahrefs. Tiny channel, disproportionately valuable.

暫定日本語案: The AEO-specific angle

暫定日本語案: AEO predates GEO と came from a different place — voice search と featured 暫定日本語案: snippets, where そのre is exactly one spoken or boxed answer. That origin is why 暫定日本語案: その AEO mental model is “be その extractable answer”: front-load a direct one-to-two 暫定日本語案: sentence answer under a clear heading, use tables と lists, keep it simple. GEO’s 暫定日本語案: origin is その LLM citation. In 2025–26 そのy’ve converged — その same structured, 暫定日本語案: front-loaded, citable コンテンツ wins both — but その distinction is worth keeping 暫定日本語案: because it tells you what you’re optimizing toward: extraction (AEO) vs. inclusion 暫定日本語案: as a cited source (GEO).

暫定日本語案: The “still SEO” case

暫定日本語案: The official positions are unambiguous. Google: “From Google Search’s perspective, 暫定日本語案: optimizing 向け generative AI search is optimizing 向け その search experience, と 暫定日本語案: thus still SEO,” とともに “no additional requirements to appear in AI Overviews or AI 暫定日本語案: Mode.” Danny Sullivan’s compression of it: “Good SEO is good GEO.” Ryan Law’s 暫定日本語案: Ahrefs piece is titled, accurately, GEO, LLMO, AEO… It’s All Just SEO. The 暫定日本語案: practitioner data agrees — most companies run AI search through そのir existing SEO 暫定日本語案: teams raそのr than a separate specialty.

暫定日本語案: That guidance is scoped to Google’s own AI features. AI Overviews と AI Mode run 暫定日本語案: on Google’s crawl, index, と eligibility systems, so Google’s “still SEO” framing 暫定日本語案: doesn’t automatically extend to ChatGPT, Perplexity, or oそのr generative products 暫定日本語案: — those run そのir own retrieval と source-selection systems outside Google’s 暫定日本語案: control, even where その underlying tactics overlap in practice.

暫定日本語案: The “actually different” case

暫定日本語案: The honest counterweight: その brと-mention inversion is not cosmetic. A site とともに 暫定日本語案: many mentions but mediocre backlinks can out-cite a high-DR site とともに fewer 暫定日本語案: mentions — something that doesn’t happen in a traditional SERP. Combine that とともに 暫定日本語案: passage-level retrieval (ページ authority no longer guarantees その citation), 暫定日本語案: citation-not-rank measurement, と a fundamentally different traffic/conversion 暫定日本語案: profile, と you have enough divergence to warrant attention even if it doesn’t 暫定日本語案: warrant a separate team. “Evolution” doesn’t mean “no change” — it means その 暫定日本語案: foundation holds while その execution layer expとs.

暫定日本語案: Keep outcomes と measurement scoped

暫定日本語案: Two guardrails be向けe you act on any of this:

  • 暫定日本語案: Don’t collapse outcomes into one score. Ranking, retrieval, context 暫定日本語案: inclusion, extraction, mention, citation, prominence, clicks, conversions, と 暫定日本語案: revenue are separate things. A tactic that moves one doesn’t necessarily move 暫定日本語案: その oそのrs — その GEO paper’s rank-5/rank-1 numbers above are about citation 暫定日本語案: frequency inside its own benchmark, not clicks or revenue. None of その SEO, 暫定日本語案: AEO, or GEO labels or tactics guarantee ranking, extraction, mention, citation, 暫定日本語案: traffic, or conversion lift; そのy’re a description of what tends to correlate, 暫定日本語案: not a promise.
  • 暫定日本語案: Scope every measurement. Google Search Console reports clicks, impressions, 暫定日本語案: CTR, と position 向け Google Search under its own documented dimensions — it 暫定日本語案: doesn’t observe ChatGPT, Perplexity, or oそのr generative products. Treat any 暫定日本語案: GEO/AEO visibility claim (including その numbers on this ページ) as tied to a 暫定日本語案: specific provider, prompt, model, market, と date; an unscoped “AI visibility” 暫定日本語案: figure isn’t measuring anything specific.

暫定日本語案: Practical priority

暫定日本語案: Do SEO first; it’s その foundation と it’s where その volume still is. Then layer 暫定日本語案: その incremental AI signals on top — none of そのm conflict とともに SEO (except keyword 暫定日本語案: stuffing, which already hurt both):

  1. 暫定日本語案: Earn brと mentions across credible third-party sites, podcasts, と 暫定日本語案: publications — その 0,664 signal.
  2. 暫定日本語案: Write passage-quality answers — every section should answer its question in 暫定日本語案: その first two or three sentences.
  3. 暫定日本語案: Establish entity clarity — consistent brと/author identity, Wikipedia/ 暫定日本語案: Wikidata, sameAs.
  4. 暫定日本語案: Keep key ページ fresh — AI assistants lean toward recently updated material.

暫定日本語案: Weight その AI signals more heavily when your audience is high-converting (B2B, 暫定日本語案: research と in向けmational intent) — that’s where その 23x conversion makes a tiny 暫定日本語案: channel worth real ef向けt. For a deeper hub on その whole topic, see 暫定日本語案: AI search optimization.
