SEO VS AEO VS GEO

The Way Users Search Is Changing

Search is evolving. For years, Search Engine Optimisation (SEO) has been at the heart of digital marketing, helping businesses improve their visibility on traditional search engines such as Google and Bing. But the way people find information online is changing rapidly.

Users are no longer simply typing keywords into a search bar and choosing a website from a list of results. They are asking questions, using voice search, interacting with AI assistants and increasingly turning to generative AI tools such as ChatGPT, Gemini, Claude and Perplexity for direct answers. At Icarus, we are changing the way we advise original content to be written to reflect this evolving search landscape.

SEO is still important, but businesses now need to consider SEO, AEO and GEO together if they want their content to remain visible as search continues to develop.

So, what is the difference between SEO, AEO and GEO?

SEO – Search Engine Optimisation

Search Engine Optimisation (SEO) is the practice of improving a website and its content so that it can rank higher in traditional search engine results.

SEO focuses on helping search engines understand what a webpage is about and determining how relevant and useful it is for a particular search query.

While search has evolved significantly, SEO remains an important foundation for digital visibility. Strong keyword research, technical performance, useful content, internal linking and authoritative backlinks can all contribute to improved organic search rankings.

Goal

Rank on Search Engines

The traditional objective of SEO is to help your website appear prominently in search engine results and attract organic traffic.

Where It Shows Up

• Google
• Bing

Focus Areas

• Keywords – Identifying and naturally incorporating the terms and phrases your target audience searches for.
• Backlinks – Building links from other reputable websites to strengthen your website’s authority.
• Technical SEO – Improving the technical foundations of a website so that search engines can crawl, understand and index it effectively.
• Core Web Vitals – Improving aspects of website performance such as loading speed, responsiveness and visual stability.
• Internal Linking – Connecting relevant pages across your website to help users and search engines discover related content.

Outcome

Higher Rankings & Organic Traffic

Effective SEO can help a business achieve stronger rankings in traditional search results, increasing visibility and driving more organic visitors to its website.

AEO – Answer Engine Optimisation

Answer Engine Optimisation (AEO) takes SEO a step further by focusing on providing clear, useful answers to the questions users are asking.

Rather than simply trying to rank a webpage for a keyword, AEO aims to make your content the best answer to a specific question or search query.

This is particularly important as search engines increasingly provide answers directly within the search results, while users are also turning to voice search and AI-powered assistants for information.

Goal

Become the Best Answer

AEO focuses on creating content that directly and clearly answers the questions your audience is asking.

Where It Shows Up

• Google AI Overviews
• Voice Search
• Featured Snippets
• AI Assistants

Focus Areas

• Question-based Content – Creating content around the questions your customers and audiences are actually asking.
• Structured Answers – Providing concise, clearly structured information that makes it easy for search engines and users to understand.
• FAQs – Answering common questions in a straightforward and useful format.
• Schema Markup – Using structured data to help search engines better understand the information and context on a webpage.
• Entity Optimisation – Helping search engines understand the people, businesses, products, places and concepts associated with your content.

Outcome

AI Citations & Direct Answers

A successful AEO strategy can increase the likelihood of your content being surfaced when search engines, voice assistants and AI-powered systems provide answers to users.

GEO – Generative Engine Optimisation

Generative Engine Optimisation (GEO) is focused on visibility within generative AI platforms.

As users increasingly ask AI tools questions instead of traditional search engines, businesses need to think about how their brand and content can be discovered, understood and referenced by generative AI.

GEO is not simply about ranking a webpage. It is about establishing your business as a credible and authoritative source that generative AI systems can recognise and reference when producing answers.

Goal

Be Referenced by Generative AI

The aim of GEO is to increase the likelihood that your business, website, expertise and content will be referenced or mentioned within AI-generated responses.

Where It Shows Up

• ChatGPT
• Gemini
• Claude
• Perplexity

Focus Areas

• Topical Authority – Demonstrating comprehensive knowledge and expertise within your area of specialism.
• EEAT (Experience, Expertise, Authoritativeness, Trust) – Building credible content and demonstrating why your business is a trustworthy source of information.
• Original Research – Providing unique insights, research, statistics and information that offer genuine value beyond what is already available online.
• Brand Mentions – Building awareness and recognition of your brand across relevant online sources.
• Semantic Relationships – Creating meaningful connections between topics, entities, concepts and information so that AI systems can better understand your expertise and relevance.

Outcome

AI Visibility & Brand Authority

The goal of GEO is to increase your visibility within generative AI and strengthen your brand’s authority across the increasingly important AI search landscape.

SEO vs AEO vs GEO: What’s the Difference?

Although SEO, AEO and GEO have different focuses, they shouldn’t be viewed as completely separate strategies.

Instead, they work together.

SEO helps your website rank in traditional search engines.

AEO helps your content become a useful and direct answer to the questions people are asking.

GEO focuses on helping your brand and content become visible and referenced within generative AI platforms.

The future of search isn’t necessarily about choosing one over another. It is about creating content that works across all three.

The Future of Search

The way people search will continue to evolve.

Traditional search engines aren’t disappearing, but they are becoming part of a much broader search ecosystem that includes AI Overviews, voice search, AI assistants and generative AI platforms.

This means businesses need to think beyond simply asking:

“What keyword should we rank for?”

Instead, content strategies should consider:

• What questions are our customers asking?
• What information does our audience actually need?
• Can we provide the best answer?
• Are we demonstrating genuine expertise?
• Is our content authoritative and trustworthy?
• Are we creating original information and insights?
• Is our brand being mentioned across relevant sources?
• Can search engines and AI systems easily understand our content?

At Icarus, this is influencing the way we approach original content. The aim isn’t simply to produce content for the sake of having more pages on a website. Content needs to be useful, authoritative, structured and genuinely valuable to the people searching for it.

From Rankings to Real Impact

SEO, AEO and GEO all have slightly different objectives, but they ultimately contribute to the same bigger goal: being found by the right people at the right time.

The future belongs to marketers who optimise for Search Engines, Answer Engines and Generative AI — together.

Search is evolving.

The businesses that adapt their content strategies today will be better positioned to build visibility, authority and trust tomorrow.
