The Rise of AI Search Engines: How to Optimise for ChatGPT and Beyond

The world of search is undergoing its most significant transformation in decades. For many years, Google dominated as the leading search engine, using algorithms such as PageRank to deliver the most relevant results. Businesses, publishers and marketers built entire strategies around Search Engine Optimisation (SEO), competing for those all-important spots on the first page of Google’s results.

Today, things look very different. A new generation of search engines has emerged, powered by artificial intelligence and large language models (LLMs). Tools such as ChatGPT, Perplexity, Claude and Google’s Gemini are not simply serving a list of links; they are providing fully formed answers, summarised insights and even personalised recommendations. These AI-driven platforms are reshaping how people find information, and in turn, how businesses must think about online visibility.

This shift has introduced a new discipline alongside traditional SEO. It is called Generative Engine Optimisation, or GEO for short. If SEO was about ranking well on Google, GEO is about ensuring your brand and your content feature within AI-generated responses. In this article, we will explore what AI search engines are, why they matter, and how you can prepare your content for this new era of discovery.

What Are AI Search Engines?

Before looking at optimisation strategies, it is important to understand what makes AI search engines different from the traditional ones we are familiar with. Conventional search engines such as Google, Bing and Yahoo work by crawling and indexing billions of pages, ranking them using a combination of factors including relevance, keywords and backlinks. They then present results in a list of clickable links.

AI search engines such as ChatGPT and Perplexity take a very different approach. Instead of presenting a list of sources, they use generative AI models to produce conversational answers. These models draw on vast datasets and sophisticated natural language processing techniques to interpret complex queries and respond in plain language. They are also designed to understand context and user intent rather than relying solely on exact keyword matches.

Consider a simple example. If you search for “best SEO tools 2025” on Google, you will receive a list of links to articles, blogs and product pages. If you ask the same question to ChatGPT, such as “What are the best AI tools for SEO in 2025?”, you are likely to receive a structured, conversational answer summarising several tools, their benefits and why they might suit your needs. This demonstrates how AI search engines focus on delivering answers rather than links, which has major implications for content strategy.

The Rise of Generative Engine Optimisation (GEO)

Just as SEO became essential when Google took over the search landscape, GEO is now emerging as a necessary response to the growth of AI-driven search. Where SEO aims to secure a high position on results pages, GEO aims to make your content appear in AI-generated responses.

The importance of GEO cannot be overstated. AI search engines are reducing the number of clicks to websites because answers are often provided within the interface itself. Voice search and AI-powered assistants are increasingly common, and they also depend on generative models to retrieve information. Brands that fail to adapt may see their visibility decline, while those that embrace GEO early can establish a strong presence within AI-driven answers.

SEO and GEO: Understanding the Differences

Although SEO and GEO share a common goal of improving online visibility, the way they achieve it is quite different. SEO is designed to meet the requirements of search engine algorithms, which rely on signals such as keyword relevance, backlinks and technical performance. GEO, on the other hand, is focused on the preferences of generative models, which prioritise content that is trustworthy, clearly written and easy to interpret.

Traditional SEO strategies often rely on keyword targeting, link building and meta data optimisation. GEO strategies involve creating structured, conversational and highly factual content that an AI model can use to construct accurate answers. Where SEO might emphasise optimising for featured snippets, GEO requires thinking about how your content can be quoted, summarised and referenced by an AI tool without losing clarity or authority.

Feature	SEO (Google)	GEO (AI Search)
Goal	Rank high on SERPs	Appear in AI-generated answers
Optimization Focus	Keywords, backlinks, technical SEO	Context, credibility, structured knowledge
Content Style	Keyword-rich, optimized for snippets	Conversational, factual, easy-to-parse
Ranking Factors	Algorithm-based signals	LLM-based trust and context
User Interaction	Click-through to site	Direct answer delivery (zero-click)

Why AI Search Engines Matter for Businesses

The rise of AI search engines has implications far beyond digital marketing teams. It will influence brand perception, traffic and even customer behaviour. When AI provides direct answers, users may never need to visit a website, which could reduce organic traffic for many businesses. At the same time, brand mentions within AI-generated answers can significantly boost authority and awareness, even if there is no click involved.

Another factor to consider is that AI-driven tools are shaping the future of voice search and conversational commerce. Consumers are increasingly using voice-activated assistants to research products, compare services and make decisions. Many of these assistants rely on generative technology, meaning the principles of GEO will be just as relevant for voice search as they are for text-based queries.

How to Optimise for ChatGPT and Other AI Search Engines

Adapting your content for AI search requires a shift in mindset. It is not about abandoning traditional SEO, but about adding new layers of optimisation that make your content suitable for generative models. Below are key principles that can help you succeed in this evolving environment.

First, create content that is clear, credible and conversational. AI tools favour material that is factually accurate, easy to summarise and written in natural language. Structuring your content around common questions and providing straightforward answers can make it easier for AI to extract and present your information.

Second, incorporate structured data wherever possible. Schema markup helps both traditional search engines and AI models understand the context and purpose of your content. Adding FAQ schema, organisation details and author information not only improves visibility but also supports Google’s E-E-A-T framework, which evaluates content for experience, expertise, authoritativeness and trustworthiness.

Third, optimise for long-tail and conversational queries. People are now asking questions in a more natural style, particularly when interacting with AI. Instead of focusing solely on short keywords, you should target full questions and related topics. Building content around topic clusters and semantic relationships will make it more relevant to generative models.

Another important step is to establish brand authority. AI systems tend to favour sources that are reputable and widely recognised. You can strengthen your position by publishing expert content, obtaining high-quality backlinks and maintaining consistency across digital channels.

Finally, ensure your content is machine-readable and easy to summarise. Use clear headings, short paragraphs and well-structured text. Avoid overly complex coding or layouts that make it difficult for AI to access the main content.

Advanced GEO Strategies

For those ready to take GEO further, consider strategies such as producing source-friendly content designed for citation by AI systems. Offer in-depth, data-driven resources that provide lasting value, and link these to recognised entities to improve trust. Creating evergreen content that answers foundational questions in your field can also help maintain long-term visibility.

The Future of Search: GEO and SEO Together

It is important to note that GEO is not replacing SEO. Instead, it is an additional layer of optimisation that reflects the changing nature of search. Google is incorporating AI-generated summaries through its Search Generative Experience, Bing is integrating AI with its Copilot feature, and other platforms are experimenting with conversational search formats. A hybrid approach that combines traditional SEO techniques with GEO principles is the best way to future-proof your digital strategy.
