How brands appear
in ChatGPT, Perplexity,
and Google AI Overviews.

A practical guide to AEO, GEO, and LLM visibility. What it is, why it matters now, and what your brand needs to do to be cited — instead of skipped — when buyers ask AI for recommendations.

In brief

By 2026, more than half of buyer research will start in an AI engine — not Google. Brands cited by ChatGPT, Perplexity, and Gemini will own that traffic. Brands that aren't, won't.

This is not theoretical. The rules of AI search are different from SEO. They're learnable, but most brands haven't started yet. The window to be early is now.

Glossary

Three terms worth knowing.

AEO
Answer Engine Optimisation

Structuring your content so AI engines can extract direct answers from it. Used when someone asks ChatGPT or Perplexity a question your brand could answer.

GEO
Generative Engine Optimisation

Making your brand cite-able by generative AI — not just findable. The difference between being mentioned in an answer and being the source the answer is built from.

LLM Visibility
Large Language Model Visibility

Whether your brand exists in the training data and live retrieval systems of GPT, Claude, Gemini, and others. Different from search rankings entirely.

Section 01 · Context

Why this matters right now.

Buyer behaviour has changed faster than most brands have adapted. A senior executive researching a vendor used to open Google, search a few queries, and land on a website. Today, that same executive opens ChatGPT and asks a direct question.

The query has changed. The expectation has changed. And the brands cited in the answer are the only ones that exist in that moment. Everyone else is invisible.

A real query, today
"Who are the best digital growth consultants in India for D2C brands? I need someone who can fix attribution, not just run campaigns."
What the AI returns
A list of 5–7 brands. Each one with a one-line description. Each one linked. The user clicks one — maybe two. Everyone else might as well not exist.

This is happening across every industry, in every market, every day. The question is not whether your buyers are using AI search — they are. The question is whether your brand is in the answer.

Figure 01

The new buyer journey. Why being cited matters more than ranking.

Buyer asks ChatGPT "Best [your category]?" AI returns 3-5 brands cited by name User clicks one maybe two Revenue earned or lost No second page. If you're not cited here → you're invisible here → and here.

In AI search, you compete to exist in the answer — not for position on a page.

Section 02 · Comparison

How AI search is different from SEO.

AEO is not a renamed version of SEO. The mechanics are different, the signals are different, and the optimisation work is different. Pretending otherwise is why so many brands are getting it wrong.

Dimension
Traditional SEO
AI Search (AEO / GEO)
User behaviour
Searches keywords. Browses results.
Asks full questions. Reads one answer.
Visibility unit
Page rankings on a SERP.
Citations inside a generated answer.
What gets rewarded
Backlinks, content depth, on-page signals.
Clarity, structure, citability, real authority.
Click-through
Multiple results, competing for clicks.
Often zero clicks. Brand mention is the win.
Time to impact
3–6 months for new content.
Faster — but compounds only if you're early.

The most important shift: in traditional SEO, you compete for position. In AI search, you compete to exist in the answer at all. If you're not cited, the user doesn't see a list of options — they see a confident recommendation. And it's not yours.

Section 03 · Frequently Asked

The questions CEOs are actually asking.

Will my existing SEO work transfer to AI search?

Partially. Strong domain authority and clean technical SEO help. But the on-page work that ranks well on Google does not automatically make you cited by AI. AEO requires its own structural rewrites — Q&A formatting, schema markup, clear definitions, and content built to be extracted as direct answers.

How do I know if my brand currently appears in AI search?

Test it directly. Open ChatGPT, Perplexity, Gemini, and Google AI Overviews. Ask the questions your buyers would ask — "best [your category] in [your market]," "alternatives to [your competitor]," "how to solve [the problem you fix]." If your brand isn't named in the answer or the citations, you're invisible. We do this audit as part of every engagement.

Which AI engines should I prioritise?

Different engines have different mechanics. ChatGPT primarily cites web sources during its browsing/retrieval calls. Perplexity aggressively cites — every answer comes with sources, making it the highest-leverage engine right now. Google AI Overviews (formerly SGE) are showing up at the top of Google searches and pulling from a different signal set. Gemini uses Google's index but with its own re-ranking. Optimising for one helps the others, but not equally.

Is this just a fad? Should I wait?

No, and no. The behavioural shift is already irreversible — anyone you know under 35 has used ChatGPT for product research in the last week. The brands that wait will arrive when AI citation is competitive and expensive. Right now, in most categories, almost no one is doing this work. The window to be early is short, and short windows are how compounding advantages get built.

How long before we see results?

Faster than traditional SEO, slower than paid media. We've seen brands appear in Perplexity citations within 30–60 days of structural rewrites and authority signals. ChatGPT browsing-based citations move faster. Training-data inclusion takes longer and is harder to control. The honest answer: it depends on your starting point and the competitiveness of your category.

Can I just hire an SEO agency to do this?

AEO requires a different skill set — content architecture, schema engineering, citation tracking, and an understanding of how LLMs retrieve and weight sources. Many SEO agencies are adding "AEO" to their offering without changing their methodology. Ask anyone you're considering to show you brands they've made cite-able in ChatGPT or Perplexity in the last 90 days. If they can't, they're learning on your time — and you're paying for it.

Section 04 · Methodology

How we make brands cite-able.

There is no shortcut. AEO is a structural discipline — it works when the underlying architecture supports it, and it fails when the foundation is off. Here is the four-step framework we use on every engagement:

The AEO Framework
4-step process
01
Citation audit — where you stand today

Run 30–50 buyer-intent queries across ChatGPT, Perplexity, Gemini, and Google AI Overviews. Map where you appear, where you don't, and where competitors are owning the answer.

02
Content rewrites for extractability

Rewrite product, category, and reference pages so AI engines can cleanly extract direct answers. Q&A formatting, defined terms, structured data, and clear authority signals throughout.

03
Schema, structure, and citation infrastructure

Deploy FAQ schema, HowTo schema, Article schema, and organisation markup. Ensure crawl-ability for AI bots. Build internal linking that reinforces topical authority.

04
Authority building outside your site

AI engines weight third-party citations heavily. We build presence in directories, comparison sites, industry publications, and review platforms — the secondary signals that make AI engines confident enough to cite you.

This is not a one-time project. AI engines update their retrieval and ranking constantly. The brands that stay visible are the ones treating AEO as an ongoing discipline — not a campaign.

Section 05 · Engagement

Where GB Digital Hub fits in.

We've been watching this shift for 18 months and building the playbook in parallel. Most of the work we do for clients now includes AEO from day one — not as a separate service, but woven into the same growth system that handles SEO, paid, analytics, and conversion.

The integration matters. AEO done in isolation produces citations without conversion. AEO done as part of an integrated growth system produces citations that lead to revenue. That's the difference.
