For more than two decades, SEO has been the foundation of digital visibility.

The formula was relatively straightforward. If your website ranked highly in Google, potential customers could discover your business, compare your products or services and eventually convert. Higher rankings generally meant more traffic, more leads and more revenue.

That model still works today. Google remains the dominant search engine globally, and organic search continues to be one of the most valuable acquisition channels available to businesses.

However, something important is changing.

AI-powered search experiences such as ChatGPT, Google AI Overviews, Gemini and Perplexity are rapidly becoming part of how people research products, services and brands. Instead of clicking through multiple search results, users increasingly receive a single generated answer that summarises information from numerous sources.

That shift is creating a new visibility challenge.

Because ranking highly in Google does not necessarily mean you'll be recommended by AI.

SEO built the internet we know today

To understand why GEO is becoming important, it helps to understand what SEO was designed to achieve.

Traditional SEO focuses on helping search engines discover, understand and rank content. The goal is to demonstrate that a page is the most relevant and authoritative result for a particular search query.

For years, businesses invested heavily in:

  • Keyword research

  • Content creation

  • Backlink building

  • Technical optimisation

  • Site speed improvements

  • Internal linking

  • User experience

When those elements aligned, websites earned better rankings and increased organic traffic.

The relationship between search engines and websites was relatively simple. Search engines provided links, users clicked those links and businesses competed for visibility within search results.

Today, that journey is becoming more complicated.

AI is changing how search works

The rise of generative AI has introduced a new layer between users and websites.

Instead of displaying a list of links and asking users to find the answer themselves, AI systems increasingly generate responses directly. Users can ask complex questions, receive summarised information and continue the conversation through follow-up prompts.

This behaviour is becoming increasingly common across major platforms.

Google has expanded AI Overviews to more than 200 countries and territories and over 40 languages, signalling just how central AI-generated responses have become to its search strategy. At the same time, OpenAI continues expanding ChatGPT Search, while Perplexity has built its entire product around AI-generated answers.

The result is a significant change in how people discover information.

Users are no longer simply choosing between websites. They are increasingly choosing between answers.

The rise of the zero-click internet

One of the biggest implications of AI search is the decline of clicks.

Research published by Bain & Company found that around 80% of consumers now rely on AI-generated summaries for at least 40% of their searches. The same report found that roughly 60% of searches end without users progressing to another website.

That doesn't mean people have stopped searching.

It means they're finding answers before they click.

For brands, this creates a new challenge. Traditional SEO success was largely measured by traffic. But if users are getting answers directly within search experiences, traffic alone becomes an incomplete measure of visibility.

A business may influence a customer's decision without ever receiving a visit to its website.

That's where GEO enters the conversation.

What is GEO?

Generative Engine Optimisation, or GEO, refers to the practice of improving visibility within AI-generated responses.

Instead of focusing solely on rankings, GEO focuses on recommendations, citations and mentions.

The goal is not simply to appear in search results. The goal is to appear in the answer itself.

This distinction matters because AI systems increasingly act as intermediaries between users and information. They decide which sources to reference, which brands to mention and which products to recommend.

In many cases, users may never see the underlying websites that contributed to an answer.

They only see the AI's interpretation.

SEO and GEO solve different problems

Although they are closely related, SEO and GEO are not the same discipline.

SEO asks:

"How do we rank higher?"

GEO asks:

"How do we get included in AI-generated answers?"

Those objectives often overlap, but they don't always produce the same outcomes.

A website might rank highly in Google while receiving very little visibility inside ChatGPT or Google AI Overviews. Conversely, a brand with strong authority signals, media coverage and structured information may appear frequently in AI responses despite not dominating traditional rankings.

Research from Princeton University, which introduced one of the first formal GEO frameworks, found that certain optimisation techniques improved visibility in AI-generated responses by up to 40%.

The implication is clear.

AI systems are making independent decisions about which sources to surface.

Why ranking number one may not be enough

For years, marketers assumed that ranking highly was the ultimate goal.

Increasingly, that's no longer the whole story.

A major 2026 study analysing more than 55,000 Google AI Overview results found that nearly 30% of domains cited by AI Overviews did not appear in the accompanying first-page search results.

In other words, AI systems are not simply copying Google's rankings.

They are selecting information based on factors such as:

  • Relevance

  • Authority

  • Context

  • Clarity

  • Citation quality

  • Source trustworthiness

This creates an entirely new competitive landscape.

Businesses are no longer competing solely for rankings. They are competing for representation.

GEO depends on machine understanding

One of the biggest differences between SEO and GEO is how AI systems process information.

Traditional search engines have historically relied heavily on keywords, links and technical signals. AI systems still use many of those inputs, but they also attempt to understand entities, relationships and context.

That means businesses need to become easier for machines to understand.

Key GEO signals increasingly include:

Entity consistency

AI systems need confidence that they understand who your organisation is.

Consistent brand information across websites, directories, social platforms and third-party publications helps reinforce those signals.

Structured data

Schema markup, FAQs, product information and clear content structures help machines interpret information accurately.

Authoritative references

AI systems frequently rely on trusted sources when generating answers. Media mentions, industry recognition and expert citations all contribute to how a brand is perceived.

Original insights

Research, proprietary data and expert commentary provide information that AI systems can reference when answering questions.

The easier your business is to understand, the easier it becomes to recommend.

SEO and GEO work better together

The most important thing to understand is that GEO does not replace SEO.

In reality, the two disciplines complement one another.

Strong SEO helps search engines and AI systems discover your content. GEO helps ensure that content is represented accurately and consistently within AI-generated answers.

Businesses that ignore SEO risk becoming difficult to discover. Businesses that ignore GEO risk becoming invisible within the fastest-growing layer of digital discovery.

The strongest strategy combines both.

Build a technically sound website. Create authoritative content. Establish strong brand signals. Earn third-party mentions. Structure information clearly.

Then measure how AI platforms actually talk about your business.

Visibility is becoming more complex

For years, digital visibility was largely a ranking problem.

Today, it is increasingly a recommendation problem.

Customers are discovering brands through ChatGPT, Google AI Overviews, Perplexity and other AI-powered experiences long before they reach a company website. In many cases, the recommendation itself becomes the first interaction a customer has with a brand.

That doesn't make SEO less important.

It simply means visibility now extends beyond traditional search results.

The businesses that succeed over the next few years won't be those choosing between SEO and GEO. They'll be the organisations that understand how both work together.

Because in the age of AI search, being found is only the beginning.

Being recommended is what matters next.
