Answer Engine Optimisation (AEO): How to Get Your Business Cited by ChatGPT and Google AI
For decades, SEO has meant one thing: ranking on Google. But in 2026, the game has fundamentally shifted. A new search channel is growing exponentially—and most businesses haven't even noticed.
This channel isn't Google. It's AI answer engines.
ChatGPT, Google Gemini, Claude, Perplexity, and dozens of other AI systems are becoming primary discovery channels. When someone asks ChatGPT a question about a product, service, or industry insight, they're not seeing a list of ranked websites. They're seeing a synthesised answer that cites sources.
And here's the critical part: if your business isn't cited, you're invisible.
This shift has given rise to a new discipline: Answer Engine Optimisation (AEO). It's the natural evolution of SEO, and it's already reshaping how forward-thinking businesses build their content strategies.
At MattDarm, we're helping UK businesses adapt to this reality. This guide breaks down what AEO is, why it matters, and how to build an AEO strategy that gets your business cited across all major AI answer engines.
What Is Answer Engine Optimisation (AEO)?
Answer Engine Optimisation is the practice of optimising content, structure, and authority signals to increase your visibility in AI answer engines and get cited more frequently.
Unlike traditional SEO—which focuses on keyword rankings and click-through rates—AEO focuses on citation frequency, authority signals, and being selected by AI systems as a trusted source.
Think of it this way:
Traditional SEO: Write content, optimise for keywords, earn backlinks, rank in Google, get clicks.
AEO: Write original, authoritative content, structure it for AI extraction, build entity authority, get cited by AI systems, and drive both direct traffic and authority gains.
The two strategies complement each other. In fact, the best AEO strategy is built on SEO fundamentals—because the authority signals that matter to Google also matter to AI systems.
Why AEO Matters Right Now
Here's the scale of the opportunity: 86% of SEO professionals now use AI in their workflows, according to 2026 research. This includes using AI to research keywords, generate content outlines, and analyse competitors.
But fewer than 20% of businesses have intentional strategies to get cited by AI systems.
The window to build a competitive advantage is closing. The businesses that dominate AEO over the next 12-18 months will own visibility across the fastest-growing information discovery channels.
The AI Answer Engine Ecosystem
Several major platforms are reshaping how people discover information:
ChatGPT & ChatGPT Search OpenAI's flagship product now has a search integration that allows users to ask questions and receive synthesised answers citing web sources. ChatGPT is used by millions daily and is rapidly becoming a primary discovery channel.
Google Gemini Google's AI answer engine is integrated into search results (Google AI Overviews) and also available as a standalone chat interface. If you're not cited in Gemini, you're missing visibility in Google's own AI systems.
Google AI Overviews These purple answer boxes appear at the top of search results, synthesising information from multiple sources. Getting cited in AI Overviews is one of the highest-impact visibility opportunities in search.
Perplexity AI Perplexity is one of the fastest-growing AI search engines and specifically focuses on citing sources. For B2B and knowledge-work industries, Perplexity is a major citation channel.
Claude (Anthropic) Claude's integration with web search means users can ask Claude questions and receive answers citing web sources. Claude has a strong presence in professional and technical communities.
Other Platforms Brave Search, Copilot, DuckDuckGo's AI features, and dozens of smaller AI platforms are all citation channels. Each one represents potential visibility.
How AI Answer Engines Choose What to Cite
To optimise for AEO, you first need to understand how AI systems select sources.
AI answer engines don't rank websites. They synthesise information and choose sources based on several factors:
1. Authority and Trust Signals AI systems use authority signals similar to Google's ranking factors: - Domain authority (overall trust in your domain based on backlinks and mentions) - Entity authority (Google's confidence that you're an expert in a specific topic) - Author expertise (whether the piece is written by a known expert) - Publication credibility (whether the source is from a trustworthy publisher)
2. Content Quality and Originality AI systems strongly prefer: - Original research and data (surveys, studies, proprietary findings) - Factual accuracy (content that can be verified against other sources) - Comprehensiveness (answers that thoroughly address the question) - Current information (recent updates, fresh data)
Thin, generic content gets deprioritised. Original insights get prioritised.
3. Structural Clarity AI systems can better extract and cite content that's: - Well-formatted (clear headings, short paragraphs, bullet points) - Logically organised (main idea first, then supporting details) - Attributed properly (sources are cited within the content) - Schema-marked (structured data that helps AI understand context)
4. Relevance to the Query AI systems match content to the specific question asked. A comprehensive guide on "SEO strategy" is only useful if the user is asking about SEO strategy. Relevance matters.
5. Recency Content published or updated recently gets higher priority. Outdated content—even if authoritative—gets deprioritised.
The AEO Strategy: 5 Core Pillars
Based on our work with UK businesses at MattDarm, we've identified five core pillars of a successful AEO strategy:
Pillar 1: Write in Q&A Format
The most frequently cited content is content that directly answers questions. This is because AI answer engines are designed to answer questions.
When you write in Q&A format, you're meeting the AI halfway. You're structuring content in the format that AI systems expect to extract.
- How to implement:
- Start blog posts with a clear question (in the H2)
- Provide a 2-3 sentence direct answer immediately after
- Then dive into supporting detail and context
For example:
Q: What is topical authority in SEO? A: Topical authority is the practice of creating comprehensive content clusters around a single topic, establishing Google's confidence that your website is an expert on that subject. Instead of writing scattered blog posts, you build a network of interconnected content that thoroughly covers every aspect of the topic.
Then expand with detail, examples, and research.
Pillar 2: Use Schema Markup and Structured Data
Schema markup (structured data) helps AI systems understand your content's context and structure. It directly impacts citation frequency.
Key schema types for AEO:
FAQ Schema Mark up your FAQ sections with FAQ schema. This signals to AI systems that your content contains question-answer pairs worth extracting.
Article Schema Mark up your blog posts with Article schema. This helps AI systems understand authorship, publication date, and content type.
How-To Schema If your content explains processes or procedures, use How-To schema. This is frequently cited by AI systems answering procedural questions.
Organization Schema Include Organization schema on your homepage with accurate company information, credentials, and contact details. This builds entity authority.
Expert/Author Schema If you have a dedicated author profile, mark it up with Person schema. AI systems prioritise content by known experts.
Implementation is straightforward. Most modern CMS platforms (including WordPress, Webflow, and Next.js) support schema markup through plugins or code.
Pillar 3: Build Entity Authority
Entity authority is Google's (and increasingly, AI systems') confidence that you are an expert in a specific field.
- Google builds entity authority through several signals:
- How often you're mentioned across the web (linked, cited, referenced)
- Whether those mentions use consistent language and terminology
- Your own consistent use of keywords, topics, and brand messaging
- Your demonstrated expertise (credentials, awards, case studies)
How to build entity authority:
Be consistently identifiable Use the same business name, spelling, and terminology everywhere. If you're "MattDarm" on your website, don't be "Matt Darm Web Design" on LinkedIn. Consistency signals authority.
Develop a core topic Don't write about everything. Own a specific domain. If you're a digital marketing agency, dominate content about digital marketing, SEO, content strategy, and paid advertising—not about accounting or tax law.
Earn authoritative citations Get mentioned on high-authority websites, in industry publications, and by recognised experts. Each citation builds entity authority.
Publish original research Surveys, case studies, and data that only you have access to are incredibly valuable for entity authority. AI systems treat original research as an authority signal.
Get credentials and badges If applicable to your industry, earn certifications, awards, or recognitions. These are authority signals AI systems respect.
Pillar 4: Create Original Research and Data
This is one of the highest-impact AEO tactics: original research that no other business can replicate.
Original research gets cited because it's unique. When you publish original findings, other content creators cite you. AI systems then cite your research when answering questions related to that topic.
Types of original research:
Surveys and polls Survey your audience or industry about trends, pain points, or preferences. Publish the results. This is immediately citable.
Case studies Publish detailed case studies with specific results. "We improved client website traffic by 340%" is more citable than generic tips.
Data analysis If you have access to proprietary data (client results, usage patterns, etc.), analyse and publish insights. This becomes a reference point.
Industry benchmarks Compile benchmarks for your industry. "Average WordPress site speed: 2.8 seconds in 2026" becomes a citation reference.
Testing and experimentation Publish results from A/B tests, experiments, or analyses. "We tested 47 landing page variations. Here are the patterns that won" is highly citable.
The businesses we work with at MattDarm that invest in original research see 3-5x higher citation rates in AI answer engines compared to those publishing generic content.
Pillar 5: Build Quality Backlinks (With Purpose)
Backlinks are still crucial for AEO, but the strategy is different. You're not chasing links for SEO juice. You're building citations from authoritative sources that will signal to AI systems that you're trustworthy.
Quality over quantity One link from a major industry publication is worth more than ten links from obscure directories. Focus on high-authority, relevant sources.
Contextual links Links that appear in relevant context (within related content) are more valuable than sidebar or footer links. A link from a blog post about your topic carries more weight than a footer link.
Link building through value Instead of outreach campaigns, create something worth linking to. Original research, comprehensive guides, and unique data naturally attract links.
Brand mentions Unlinked brand mentions are increasingly important. When people mention your business without linking, AI systems note that. Build brand visibility and mentions will follow.
Our digital marketing services include strategic link building focused on authority and relevance, not just quantity.
Technical AEO: Implementation Best Practices
Beyond content strategy, several technical factors impact AEO performance:
1. Ensure Content is Crawlable AI systems' citation abilities depend on being able to crawl and understand your content. - Avoid heavy JavaScript that hides content - Don't gate important content behind logins - Ensure content is publicly accessible - Use clean, semantic HTML
2. Implement Proper Canonicalisation If you have duplicate or similar content across your website, use canonical tags to clarify which version should be cited. AI systems won't cite both versions—they'll choose the canonical.
3. Use Clean, Descriptive URLs URLs like `/blog/how-to-improve-seo/` are better than `/blog/?p=2847`. Descriptive URLs help AI systems understand content context.
4. Optimise Core Web Vitals Site speed and mobile performance matter for AEO. AI systems crawl faster sites more frequently and completely.
5. Maintain an Updated Sitemap An up-to-date XML sitemap helps AI systems discover and crawl your latest content.
6. Use Consistent Heading Structure Proper H1, H2, and H3 hierarchy helps AI systems understand content structure and importance.
Tracking AEO Performance: New Metrics
Traditional SEO metrics—rankings and traffic—don't tell the whole AEO story. We recommend tracking:
1. AI Citation Frequency How often does your content appear in ChatGPT responses, Google AI Overviews, and other AI answer engine outputs? Tools like Semrush, Ahrefs, and emerging AEO-specific tools can track this.
2. Citation Rate by Topic Which topics generate the most AI citations? Double down on those.
3. Featured Snippet Rate Featured snippets are frequently cited by AI systems. Track what percentage of your target keywords have snippets, and how many are yours.
4. Domain Authority Trend Are backlinks and citations increasing? This affects both SEO and AEO performance.
5. Search Visibility (Not Just Rankings) Are you visible in search results, even if you're not in position one? SERP visibility is more important than ranking position.
6. Entity Authority Indicators Track mentions of your brand across the web. Increase in mentions = increase in entity authority = increase in AEO visibility.
7. Branded Search Volume More direct searches for your business indicate growing brand authority, which benefits both SEO and AEO.
Why AEO Favours Small Businesses
Here's something that might surprise you: AEO strategy actually favours small and medium-sized businesses over large corporations.
Why? Because large enterprises often publish low-quality, bloated content. They prioritise quantity over quality. Meanwhile, smaller businesses like our clients can publish thoughtful, well-researched, original content that AI systems prefer.
A one-person consultancy that publishes one exceptional, well-researched piece of content per month will get more AI citations than a large publisher that cranks out five mediocre posts per day.
This is where we focus heavily in our content marketing services—helping SMEs create citation-worthy content that competes with larger competitors on visibility and authority.
AEO and SEO: A Unified Strategy
The best news: AEO and SEO strategies work together. The authority signals that help you rank in Google also help you get cited by AI.
In fact, our recommended approach is unified:
- Research keywords and questions (traditional SEO)
- Identify citation opportunities (new AEO thinking)
- Create original, authoritative content (both SEO and AEO)
- Optimise for both clicks and citations (unified approach)
- Build authority through links and mentions (both SEO and AEO)
- Track both rankings and citation frequency (unified metrics)
The days of pure "SEO strategy" are ending. The businesses winning in 2026 are those with unified "search visibility strategy" that includes both Google rankings and AI citations.

The Future of Search is Citation
If you take one thing from this guide, let it be this: the future of search is citation, not ranking.
Google will continue to evolve. AI answer engines will continue to proliferate. But the fundamental shift is clear: being cited by trusted sources is becoming more important than ranking in positions.
The businesses that adapt their strategy from "how do I rank?" to "how do I become the trusted source that gets cited?" will own visibility in search for the next decade.
That's AEO. And it's the most important SEO evolution since mobile-first indexing.
If you're ready to build an AEO strategy for your UK business, our team at MattDarm specialises in helping SMEs compete on authority and citation frequency. Get in touch to discuss your AEO strategy.
FAQs: Answer Engine Optimisation
Q1: Is AEO replacing traditional SEO? No. AEO is complementary to SEO. The authority signals that help you rank in Google also help you get cited by AI. We recommend a unified "search visibility strategy" that optimises for both clicks and citations. Traditional SEO isn't dead—it's evolving.
Q2: How long does it take to see AEO results? Initial results (first citations in AI systems) typically appear within 3-4 months. Significant citation growth usually takes 6-12 months. This timeline is similar to SEO, with one difference: original research can drive citations much faster (2-4 weeks).
Q3: Should I create separate content for AEO? No. The best approach is to create content that works for both traditional Google search and AI answer engines. Write original, authoritative content in Q&A format, optimise structure, build authority, and you'll naturally perform well in both channels.
Q4: Which AI platforms should I focus on? Start with Google AI Overviews (integrated with search) and ChatGPT (fastest-growing). Then expand to Perplexity, Claude, and others. Our recommendation: monitor citation frequency across all platforms, then focus budget on the ones driving the most citations in your industry.
Q5: Can I pay for citations in AI answer engines? No. Unlike Google Ads, there's no paid way to guarantee citations in AI answer engines. Citations are earned through authority, quality, and relevance. This actually favours businesses with genuine expertise over those with big advertising budgets.
Q6: How do I know if AEO is working for my business? Track these metrics: (1) AI citation frequency (how often you appear in ChatGPT, Gemini, etc.), (2) branded search volume (direct searches for your business), (3) referral traffic from AI platforms, (4) entity authority indicators (brand mentions across the web). If all four are increasing, your AEO strategy is working.
