Search is evolving rapidly. While traditional search engines like Google are still essential, more users now use AI tools.
They use platforms like ChatGPT, Perplexity, and Claude.
They also use AI-generated search summaries to find information.
Instead of clicking through multiple websites, users can now receive direct answers generated by artificial intelligence.
This shift is reshaping how people discover content online – and it’s changing how businesses need to approach SEO.
The good news is that many of the principles behind strong search visibility remain the same. However, to succeed today, organisations must expand their strategies. They should include both traditional search engines and AI-powered search experiences.
This guide explains how SEO is changing, what still matters, and how to build a content plan. It works well in search engines and AI systems.
What Is AI Search?
AI search is an evolution of search.
It uses artificial intelligence to create answers to user questions.
Examples include:
- AI-generated answers in search engines
- Chat-based AI tools such as ChatGPT and Claude
- AI-powered search platforms like Perplexity
- Search results enhanced by AI summaries
Instead of selecting one webpage, users receive a synthesised answer generated from multiple sources across the internet.
AI systems analyse large amounts of information, identify relevant sources, and combine insights to provide a comprehensive response.
This fundamentally changes how people discover content online.
How AI Search Is Changing SEO
For years, SEO largely followed a consistent framework:
- Identify keywords your audience searches for
- Create content targeting those keywords
- Optimise pages to rank in search results
- Drive traffic from those rankings
While these steps remain important, AI search introduces a dynamic: users may receive answers without visiting websites.
People call these zero-click searches. Users get the information they need from an AI-generated response.
Because of this, the role of SEO is expanding beyond rankings and traffic.
Today, visibility also includes:
- Brand mentions within AI responses
- Citations of your content as a trusted source
In other words, success is no longer only about driving clicks.
This means organisations need to showcase their expertise wherever answers are generated.
What Hasn’t Changed in SEO
Despite the technological shift, many core SEO principles remain unchanged.
Search engines and AI systems still prioritise the same fundamental qualities:
Understanding your audience
Successful content answers real questions your audience is asking.
Understanding their problems, interests, and needs remains the foundation of effective content marketing.
Creating genuinely useful content
High-quality content that provides value will always outperform content created purely for algorithms.
Demonstrating expertise
Authority and credibility continue to be major ranking signals.
Websites that regularly publish helpful, accurate, detailed content are more likely to appear in search results. They are also more likely to appear in AI systems.
Building topical authority
Search engines reward websites that demonstrate deep expertise in specific subject areas.
This concept of topical authority is becoming even more important in AI search.
The Importance of Topical Authority in AI Search
Topical authority refers to how well a website demonstrates expertise on a particular subject.
Instead of publishing isolated articles on unrelated topics, strong content strategies focus on owning a specific subject area.
When search engines and AI systems see a website that often covers related topics, they see it as a trusted source.
This increases the likelihood that your content will:
- rank for related keywords
- be cited by AI platforms
- build trust with users
One of the most effective ways to build topical authority is through content pillars and topic clusters.
Building Content Pillars and Topic Clusters
A pillar-and-cluster structure organises content around key themes that matter to your audience.
Pillar content
A pillar page is a comprehensive guide that covers a broad topic in depth.
Pillar content typically:
- targets broader keywords
- provides a detailed overview
- links to more specific articles
Cluster content
Cluster articles are individual pieces of content that explore specific aspects of the main topic in greater detail.
Cluster content typically:
- targets more specific or long-tail keywords
- focuses on answering particular questions or subtopics
- links back to the pillar page and to related cluster articles
Each cluster article links back to the pillar page and to related content.
This structure helps search engines understand how your content connects and reinforces your expertise on the topic. It also creates a better user experience by helping readers explore related information easily.
Keyword Research in the Age of AI Search
Keyword research is still an essential step in content strategy.
However, the types of queries people search – and how they search – are evolving.
Users increasingly ask conversational questions, especially when interacting with AI tools.
This makes long-tail keywords particularly valuable.
What are long-tail keywords?
Long-tail keywords are longer, more specific search phrases that usually have lower search volume but clearer intent.
For example:
Instead of targeting:
“SEO tools”
You might target:
“best SEO tools for small businesses”
Long-tail keywords often reflect the types of questions users ask AI platforms directly.
They also tend to attract more engaged visitors because the search intent is clearer.
Creating Content for Humans, Search Engines and AI
Today’s content must satisfy three audiences simultaneously:
- human readers
- search engines
- AI systems
Fortunately, the principles behind strong content remain the same.
A widely recognised SEO framework is E-E-A-T.
What is E-E-A-T?
E-E-A-T stands for:
- Experience
- Expertise
- Authoritativeness
- Trustworthiness
These signals help search engines and AI systems determine which sources are reliable.
- Experience
Content should reflect real-world experience or practical insight.
- Expertise
Demonstrating subject knowledge builds credibility.
- Authoritativeness
Authority is built through consistent publication of high-quality content and recognition from other trusted websites.
- Trustworthiness
Accurate information, secure websites, and transparent authorship all contribute to trust.
AI platforms rely on similar signals when deciding which sources to cite.
Structuring Content for SEO and AI Discoverability
Beyond writing great content, structure and optimisation play an important role in discoverability.
Use clear heading structures
Organise content using:
- H1 for the page title
- H2 for main sections
- H3 for subsections
Clear structure makes it easier for both readers and algorithms to understand the content.
Question-based headings are particularly useful because they mirror how users phrase search queries.
Use keywords naturally
Target keywords should appear in:
- titles
- headings
- introductions
- body content
However, avoid keyword stuffing. Modern search algorithms prioritise natural language and context.
Internal linking
Internal links connect related content across your website.
Benefits include:
- helping users navigate related topics
- improving search engine understanding of your site structure
- reinforcing topical authority
Structured data
Structured data (also known as schema markup) helps search engines understand the type of content on your page.
Common schema types include:
- article schema
- FAQ schema
- how-to schema
- review schema
Content freshness
Regularly updating content signals that your information remains current and relevant.
Search engines and AI platforms favour up-to-date sources.
Why AI Visibility Extends Beyond Your Website
One of the most significant changes introduced by AI search is how information is gathered.
Traditional search engines rely on indexed web pages.
AI platforms often use query fan-out. This process collects information from many internet sources to generate an answer.
These sources may include:
- news websites
- discussion forums
- Q&A platforms
- industry blogs
- review sites
- social communities
Because of this, businesses should think beyond their own websites when building authority.
A strong presence on trusted platforms makes it more likely that AI will mention or cite your brand.
The Future of SEO and AI Search
AI search is reshaping how people find information, but it doesn’t replace SEO.
Instead, it expands the scope of what SEO involves.
The organisations that succeed will focus on:
- creating genuinely valuable content
- building authority within specific topics
- structuring information clearly
- maintaining visibility across the wider web
Ultimately, the goal remains unchanged: provide helpful, credible answers to the questions your audience is asking.
The difference today is that those answers may appear not only in search results, but also in AI chats.
Turning AI Search Strategy into Action
Understanding how AI search and SEO work together is the first step. The next challenge is turning that knowledge into a practical strategy that delivers real results.

Frequently Asked Questions
What is AI search and how does it work?
AI search is an advanced form of search that uses artificial intelligence to generate direct answers to user queries. Instead of showing a list of links, platforms like ChatGPT, Perplexity, and Google AI summaries analyse multiple sources and provide a single, synthesised response. This means users can find information faster without needing to visit multiple websites.
How is AI search changing traditional SEO?
AI search is changing SEO by reducing reliance on clicks and increasing the importance of visibility within AI-generated responses. While rankings still matter, businesses now need to focus on brand mentions, citations, and authority across the web. ExtraDigital helps organisations develop strategies that improve both search rankings and visibility in AI-generated answers.
What is topical authority and why is it important?
Topical authority refers to how well a website demonstrates expertise in a specific subject area. Search engines and AI platforms prioritise sources that consistently publish high-quality, relevant content on a topic. Building topical authority increases the chances of ranking well and being cited in AI responses.
Are keywords still important in the age of AI search?
Yes, keywords remain important, but the focus has shifted toward conversational and long-tail queries. Users increasingly ask detailed, question-based searches when using AI tools. Targeting these queries helps attract more relevant traffic and improves the likelihood of appearing in both search results and AI-generated answers.
How can businesses optimise content for both search engines and AI platforms?
Businesses should create high-quality, well-structured content that follows E-E-A-T principles (Experience, Expertise, Authoritativeness, Trustworthiness). Clear headings, internal linking, and structured data all improve discoverability. ExtraDigital supports organisations by building content strategies designed to perform across both traditional search engines and AI platforms.
