AI Search Optimisation: GEO, AEO and Google AI Mode Explained

Why AI results now shape discovery and conversion

Search used to point people to a list of blue links; now, assistants and answer engines
write short, confident answers at the top of the page and show a handful of sources beneath.
That change moves the first impression and a lot of intent into the answer itself. If your brand shows
in that block, you set the frame for the click and often for the purchase; if you don’t, someone else does.

Studies from SparkToro and
Similarweb show that “zero-click” searches already account for a large share of queries.
Google’s AI Overviews amplify that effect because they satisfy quick questions and shorten the path from search to purchase.

What this guide will teach you

This guide explains AI search in plain English, separates
Generative Engine Optimisation (GEO) from
Answer Engine Optimisation (AEO) and classic SEO, and shows how
Google AI Mode presents, cites, and rewards clear sources.

You’ll see page patterns that get quoted, an entity-first site structure that reduces confusion,
a digital PR approach that wins mentions, a technical checklist for structured data, an ecommerce playbook,
and a measurement model that tracks inclusion and business impact.

Who this is for

If you run a business or lead marketing, and you want practical steps with proof points you can monitor,
this is for you. The aim is clarity you can act on this month, not a theory piece that gathers dust.

What AI Search Actually Is

From documents to direct answers

Classic search ranked documents and left users to pick. AI search writes a direct answer,
then cites sources next to the claim. That means your page needs statements that can be extracted
with high confidence, plus signals that show the claim is current and credible.

How assistants summarise and cite sources

Modern assistants index and segment pages, compare overlapping claims, and try to produce
a short answer that covers the core of the query. They tend to prefer sentences that name
the thing and the value, small tables with labelled rows and columns, and sections that make
scope explicit.

When the assistant states a fact, it will often show a source tile or inline link
anchored near the relevant claim. This is why definition boxes, feature tables, and numbered
steps help: they reduce ambiguity and shorten the distance between a claim and its evidence.

Where traditional listings still win

AI answers don’t replace everything. Local intent, visual shopping, and deep research still push
users to standard listings, map packs, product grids, and long-form guides. If a user wants to
compare several brands or to read full reviews, the assistant points down the page. Your plan
should cover both: concise, quotable facts for quick answers and rich, navigable pages for
considered decisions.

Where AI answers appear

Google AI Mode

Google’s AI experience, sometimes called
AI Overviews,
sits near the top of the results page for many queries. It typically shows a short paragraph or bullet points,
a set of source tiles, and a row of follow-up prompts. Layouts vary by query type, but the principle is constant:
a compact answer with citations. If your page provides a clear, supported claim that maps to the query, you can
earn those source positions.

Chat assistants and answer engines

Chat-style systems such as Microsoft Copilot, ChatGPT with browsing, and
Perplexity present answers in a conversational flow
with inline links and source previews. They often draw from high-clarity pages, official documentation,
knowledge bases, and news. AEO work focuses on becoming an obvious pick in those pools by reducing entity confusion
and publishing concise, well-scoped content that can stand on its own.

How sources are selected

Clarity, coverage, freshness, reputation

Clarity means short, concrete sentences, explicit labels, and simple structure.
Coverage means the page handles the query scope without drifting.
Freshness means visible dates, updated facts, and current stock or prices.
Reputation comes from author identity, publisher trust, third-party mentions, and reviews.

Structured data
such as Organisation, Product, FAQ, HowTo, and Article schema helps assistants match claims to the right entities.

GEO, AEO and Classic SEO

Clear definitions in one place

Generative Engine Optimisation

GEO
is the practice of making your content easy for generative systems to quote. It focuses on extractable statements,
clean structure, schema, and nearby evidence such as data points, citations, and screenshots.

Answer Engine Optimisation

AEO aims to increase your presence in answer engines and chat assistants. It includes entity clarity across the open web,
prompt coverage, and distribution of concise explainers that answer common questions with sourceable claims.

How these relate to SEO

Classic SEO remains the foundation—crawlability, content quality, links, and UX. GEO and AEO sit on top. If your site is
hard to crawl or vague, AI has little to quote and little reason to trust you.

When to focus on each

Informational, transactional, brand and product use cases

For informational queries, GEO is key: definitions and how-tos.
For transactional, use both: show price, delivery, and returns up top.
For brand, focus on entity clarity: consistent names and profiles.
For product, enrich data: attributes, stock, warranties, delivery.

Shared foundations

Crawlability and site hygiene

Keep navigation simple, fix 404s, use canonicals, submit sitemaps, and keep robots.txt open for public pages.

Quality content and links

Answer questions early, back claims with sources, and earn links from relevant outlets.
BrightLocal’s 2023 survey
found 98% of consumers read reviews, highlighting the value of proof content.

Evidence and credibility signals

Show author names, dates, methods, and policies. These align with
Google’s people-first content guidelines
and the Search Quality Rater Guidelines.

Google AI Mode in Plain English

What changes on the results page?

Layout overview

For eligible queries, the page can open with an AI block: a compact summary, sources, and follow-ups.
Google documentation
shows layouts vary by device, but the principle remains: a concise answer with citations.

Where citations come from

They come from pages that match phrasing and scope, with schema and clear entities.

How to be cited

Page types and evidence blocks

• Definition pages with “What is X” boxes
• Comparison pages with tables
• How-to guides with numbered steps
• Product pages with price, returns, and delivery

Examples of extractable statements

“Generative engine optimisation helps pages appear in AI answers.”

“Free UK returns within 30 days.”

“Warranty: 24 months, parts and labour.”

Implications for paid media and CRO

Shorter paths to purchase

AI answers preload price and policies, so clicks carry high intent. Ensure landing pages match promises.
The Baymard Institute reports
abandonment rates near 70%, so reducing friction matters.

Proof content, reviews and policy clarity

Place ratings and policies in facts boxes. Consistency across site, feeds, and ads increases trust and citation chances.

Measurement and Reporting

Ensure that you are regularly checking in on AI traffic. You can create custom reports in Google Analytics,
such as the one we use for clients.

We use this to track improvements, leads and revenue on a monthly basis.

Conclusion

The takeaway

Make facts easy to quote, define entities clearly, earn credible mentions, and track inclusion and conversions.
