AIEO.
SEO wins the click.
We win the sentence.

AI Engine Optimisation — also called GEO or AEO. The discipline of getting your brand cited and well-described inside ChatGPT, Claude, Gemini, Perplexity and Grok.

AIEO (AI Engine Optimisation) is the practice of monitoring and shaping how a brand appears across LLM-based answer engines. Where SEO optimises ten blue links on a results page, AIEO optimises the sentence the model produces when the user never clicks.

Practitioners call the same discipline GEO (Generative Engine Optimisation) or AEO (Answer Engine Optimisation). The acronym varies. The workflow is identical.

Roughly 40% of B2B research queries are resolved without a click in 2026. If your brand isn't in the sentence the model produces, you aren't in the consideration set — no matter where you rank on Google.

The Prompt & Pencil AIEO platform tracks, diagnoses and ships updates against five engines weekly.

§ 01 / Defined

What AIEO actually is.

AIEO is one of three names for the same discipline. The acronyms collided as the field formed in 2024–2025.

Acronym Stands for Most common in
AIEOAI Engine OptimisationAPAC practitioners, our preferred term
GEOGenerative Engine OptimisationUS academic and enterprise contexts
AEOAnswer Engine OptimisationOlder term, dating to featured-snippet work in 2019

All three describe the same job: get your brand cited and well-described in AI answer engines. We use AIEO because it travels better in mixed APAC-Western teams and doesn't get confused with geographic SEO.

§ 03 / How we work

Track. Diagnose. Ship.

Three loops. Weekly cadence. Same four numbers on the dashboard every Monday.

01 / TRACK

A prompt panel of 50–200 queries, asked weekly to all five engines.

We co-design the panel with your team — competitor framings, category questions, brand-defence prompts, hostile probes. Every prompt is asked weekly to ChatGPT, Claude, Gemini, Perplexity and Grok. Outputs feed the four-KPI dashboard.

02 / DIAGNOSE

What does each model know — and what does it get wrong?

We compare answers across engines, flag factual drift, surface competitor framings the model has internalised, and map citation provenance: which URLs (yours and others') are feeding the answers right now.

03 / SHIP

Structured updates that move the needle in days.

Each cycle produces a punch list: schema deltas, FAQ additions, off-site placements (Reddit, Wikipedia, Quora), data-asset publishing. Most clients see measurable Mention Rate movement within 6–8 weeks of consistent execution.

§ 04 / The new dashboard

Four numbers replace 'rank #1'.

These four metrics are what we report to clients every Monday morning. Tracked across all five engines and the full prompt panel.

KPI / 01
M%
Mention Rate
% of prompts in which your brand appears in the answer at all. The first hurdle. If you're not mentioned, nothing else matters.
KPI / 02
C%
Citation Rate
% of answers that link to your URL. Mentions without citations are weaker — they don't drive any traffic.
KPI / 03
P
Position
Average paragraph at which your brand appears. Top of answer beats footnote. Roughly the AI equivalent of organic position.
KPI / 04
±
Sentiment
Directional read of how the model describes you. Positive, neutral, hedged or critical. Drives the rewriting work in the next cycle.
§ 05 / Coverage

Five engines, one weekly cycle.

Coverage expands quarterly as new answer engines pass a usage threshold.

ChatGPT
CONSUMER · LARGEST
Largest share of consumer AI traffic. ChatGPT Search retrieves via Bing's index — clean SEO foundation feeds both.
Perplexity
COMMERCIAL · HIGH-INTENT
Smaller user base but the highest commercial intent. Cites sources by default. The fastest engine to move with structured content.
Claude
B2B · ENTERPRISE
Enterprise and developer audiences. Strong long-form reasoning. Critical for B2B SaaS, consulting, infrastructure brands.
Gemini
GOOGLE · OVERVIEWS
Tied into Google's AI Overviews. The crossover layer where SEO and AIEO meet. If you rank in Google, you have a head start here.
Grok
X-NATIVE · FAST CYCLE
X-native audience and the fastest news cycle of the five. Disproportionately important for consumer launches and reputation events.
§ 06 / Frequently asked

The questions buyers ask AI
before they ask us.

Q—01

What is AIEO (AI Engine Optimisation)?

AIEO is the practice of monitoring and shaping how a brand is described inside AI answer engines — ChatGPT, Claude, Perplexity, Gemini and Grok. Where SEO optimises ten blue links, AIEO optimises the sentence the model produces when the user never clicks. Same discipline is also called GEO (Generative Engine Optimisation) or AEO (Answer Engine Optimisation).
Q—02

Is AIEO the same as GEO or AEO?

Yes — same discipline, three acronyms. AIEO (used in APAC), GEO (US academic / enterprise), AEO (older term from featured-snippet work). All three describe the work of getting your brand cited and well-described inside AI answer engines.
Q—03

How is AIEO different from SEO?

SEO ranks pages. AIEO shapes answers. SEO is page-level (one URL, one query). AIEO is sentence-level (one prompt, one answer, citing 2–5 URLs invisibly). Both reward schema, freshness and authority. AIEO additionally rewards factual density, citation-friendly structure, recency under 90 days, and off-site presence on Reddit, Wikipedia and YouTube.
Q—04

How do I get cited by ChatGPT, Claude and Perplexity?

Six moves, in order. (1) Allow GPTBot, OAI-SearchBot, ClaudeBot, anthropic-ai, PerplexityBot and Google-Extended in robots.txt and on Cloudflare. (2) Add JSON-LD schema (Organization, Article, FAQPage, Product). (3) Publish original data no one else has. (4) Restructure pages with question-format H2s and inverted-pyramid answers in the first 40–60 words. (5) Build off-site authority on Reddit, Quora and Wikipedia. (6) Update important pages every 7–14 days.
Q—05

What KPIs measure AIEO success?

Four numbers. (1) Mention Rate — % of prompts where you appear. (2) Citation Rate — % of answers that link to your URL. (3) Position — average paragraph you land in. (4) Sentiment — how the model describes you. Tracked weekly across 5 engines and 50–200 prompts. These four replace 'rank #1' as the AIEO scorecard.
Q—06

How fast does AIEO show results?

Retrieval-based engines: 2–4 weeks. Parametric knowledge: 6–12 months. ChatGPT Search, Perplexity and Google AI Overviews can cite a new page within a single index cycle. The model's underlying knowledge only updates on the next training run. AIEO programmes usually show measurable Mention/Citation Rate movement within 6–8 weeks of consistent execution.
Q—07

Which AI engines should I monitor first?

ChatGPT first, then Perplexity, then add Claude for B2B. For most B2C brands ChatGPT + Perplexity + Google AI Overviews covers 80% of meaningful traffic. For B2B add Claude. Grok and Gemini fill in the picture but rarely lead the priority list unless you have an X-native audience or a Google AI Overviews exposure.
