SEO vs AEO vs GEO: Understanding the New Search Landscape

Search is evolving faster than ever.

For years, Search Engine Optimisation (SEO) was the primary way businesses improved online visibility. Today, users increasingly rely on AI-powered tools such as ChatGPT, Google AI Overviews, Gemini, Perplexity, and Claude to find information, compare products, and discover local businesses.

As a result, new optimisation strategies have emerged, including Answer Engine Optimisation (AEO) and Generative Engine Optimisation (GEO).

But what do these terms actually mean, and how do they work together?

Let's take a look at how SEO, AEO, GEO, and other important search visibility disciplines are shaping the future of digital marketing.

What Is SEO?

SEO (Search Engine Optimisation) is the practice of improving a website's visibility in traditional search engine results.

The goal is simple: rank higher for relevant keywords and attract organic traffic.

SEO typically includes:

Keyword research
Technical SEO
On-page optimisation
Link building
Content marketing
User experience improvements

For example, if someone searches:

"best local SEO agency UK"

SEO aims to help your website appear prominently in Google's search results.

What Is AEO?

AEO (Answer Engine Optimisation) focuses on helping content appear within AI-generated answers.

Rather than competing solely for rankings, AEO aims to position your content as a trusted source that answer engines use when generating responses.

AEO platforms include:

ChatGPT
Google AI Overviews
Gemini
Perplexity
Microsoft Copilot
Claude

When a user asks:

"What is the best CRM for small businesses?"

An answer engine may generate a summary using information from multiple websites. AEO helps your content become one of those sources.

What Is GEO?

GEO (Generative Engine Optimisation) is the process of optimising content, brand authority, and digital signals to increase visibility within AI-generated search experiences.

While AEO often focuses on individual answers, GEO takes a broader view of how AI models discover, understand, and reference brands.

GEO strategies include:

Building topical authority
Digital PR
Brand mentions
Entity optimisation
Structured data
Expert-led content
Knowledge graph visibility

Think of GEO as the evolution of SEO for AI-powered search ecosystems.

SEO vs AEO vs GEO

Factor	SEO	AEO	GEO
Primary Goal	Rank webpages	Appear in answers	Increase AI visibility
Focus	Search engines	Answer engines	Generative AI platforms
Success Metric	Rankings and traffic	Citations and mentions	Brand presence across AI systems
Target	Keywords	Questions	Topics, entities, and authority
Platforms	Google, Bing	ChatGPT, Gemini, Perplexity	AI ecosystems broadly

Rather than competing strategies, SEO, AEO, and GEO work best together.

What Is Local SEO?

Local SEO focuses on improving visibility for location-based searches.

Examples include:

Plumber near me
Accountant in Manchester
Local SEO agency London

Local SEO typically involves:

Google Business Profile optimisation
Reviews management
Local citations
Location pages
Local link building

Strong local SEO is increasingly important for AI-generated local recommendations.

What Is Local AEO?

Local AEO extends traditional local SEO into AI-powered search.

Instead of ranking only in Google Maps, businesses aim to appear when users ask AI tools questions such as:

Who is the best solicitor in Leeds?
Which local SEO agency should I hire?
What are the top-rated restaurants near me?

AI systems often rely on signals from local SEO, making both disciplines closely connected.

What Is Entity SEO?

Entity SEO focuses on helping search engines understand who or what your business represents.

Google increasingly relies on entities rather than keywords alone.

Examples of entities include:

Brands
People
Companies
Locations
Products
Organisations

Entity optimisation helps search engines and AI models build confidence in your expertise and authority.

What Is E-E-A-T?

E-E-A-T stands for:

Experience
Expertise
Authoritativeness
Trustworthiness

Although not a ranking factor itself, E-E-A-T heavily influences how Google and AI systems evaluate content quality.

Strong E-E-A-T signals include:

Expert authors
Original insights
Real-world experience
Industry credentials
Trustworthy sources

These signals are becoming increasingly important in both SEO and GEO.

What Is Digital PR?

Digital PR helps businesses earn mentions, links, and authority across the web.

Benefits include:

Brand awareness
Backlinks
Entity recognition
AI visibility
Improved trust signals

Many GEO strategies depend heavily on strong digital PR campaigns because AI systems often reference brands that are discussed across authoritative websites.
