What Is AEO?
The Complete Guide to Answer Engine Optimisation
Answer Engine Optimisation (AEO) is the practice of making your brand visible, credible, and recommendable across AI search platforms: ChatGPT, Perplexity, Gemini, Google AI Overviews, and what comes next.
Most agencies approach this as a content and links problem. We approach it as a brand systems problem, because AI doesn't just read your content. It evaluates your design, your structure, your experience, your authority. That's why we built the 7 Signals framework: to diagnose exactly where your brand is visible, where it's invisible, and what to fix first.
- Answer Engine Optimisation (AEO)
Also known as generative engine optimisation (GEO) OR AI SEO, is the practice of making your brand discoverable, citable, and recommendable by AI systems, including ChatGPT, Perplexity, Google AI Overview, and other AI-powered answer engines.
The 7 Signals Framework
AI doesn't recommend brands it doesn't understand. To earn AI visibility, your brand needs to send clear, consistent, and structured signals across 7 dimensions, organised in three tiers.
Tier 1 — Strategic Foundation
Brand Signal sits at the top. It defines who you are, who you serve, and what makes you different. Without it, every other signal lacks direction.
Brand Signal
The foundational layer. It defines who you are, what you stand for, who you serve, and what makes you different, articulated in ways AI can parse and repeat.
Tier 2 — Owned Presence
These three signals cover everything on your own site: how it feels (Experience), what it says (Content), and how AI agents can access it (Agent). You have full control here.
Experience Signal
The quality of the on-site experience after AI recommends your brand. It covers your visual identity, the clarity and consistency of your copy, how accessible and usable your site is across devices, and whether key conversion pages are easy to find and act on.
Content Signal
The body of content on your owned properties, structured so AI can extract, understand, and cite it. This is where most AEO advice starts. We believe it's the third signal, not the first.
Search Signal
The bridge between traditional SEO and AI search. It uses your existing keyword data, search rankings, and SERP performance as inputs to strengthen your AEO strategy. Strong SEO feeds AI credibility. Your search data tells you what your audience cares about.
Tier 3 — External Presence
These three signals cover everything beyond your site: your search visibility (Search), your social footprint (Social), and what third parties say about you (Authority). You influence these but don't fully control them.
Social Signal
Your brand's footprint across social platforms. AI systems increasingly source information from social content. Reddit threads, LinkedIn posts, YouTube transcripts, and Substack newsletters all feed into AI training data and real-time retrieval.
Authority Signal
The independent, third-party validation of your brand across the web. It determines whether AI trusts your brand enough to recommend it, not just cite it. Think of it as the difference between a CV (your content) and references (what others say about you).
Agent Signal
This is the technical layer. Your site's ability to be crawled, parsed, and understood by AI agents. This covers structured data, schema markup, crawl accessibility, and emerging AI-agent protocols like WebMCP.
How We Apply the 7 Signals to Projects
Phase 1: Brand Signal Foundation
We start every engagement by defining the Brand Signal. A strategic articulation of who you are, who you serve, and what makes you defensibly different.
Phase 2: Audience-First Prompt Mapping
Using our 4-source methodology (CRM → User Research → SEO Data → Social Listening), we build a prompt list with up to 80% accuracy.
Phase 3: Owned Presence Audit
We assess the three signals you fully control. Experience Signal (site UX and conversion paths), Content Signal (what your site says), and Agent Signal (how AI agents access your site). This produces a prioritised action plan for your owned properties.
Phase 4: External Presence Audit
We assess the three signals beyond your site. Search Signal (your current SEO performance), Social Signal (your platform footprint), and Authority Signal (what third parties say about you). This reveals where external perception gaps exist.
Phase 5: Signal Engineering
We execute across the signals that move the needle fastest, starting with the weakest links identified in Phases 3 and 4.
Phase 6: Measurement
AEO is an awareness and consideration play. ROI shows up as increased bot crawl activity, improved citation metrics, first-time visits from AI referral sources, and overall brand metric uplift.

How to build your prompt for AEO tracking
Most AEO practitioners auto-generate prompt lists from tools, which is essentially guessing what users ask AI. A robust prompt strategy draws from 4 real data sources. With these 4 inputs combined, you can build a prompt list with up to 80% accuracy versus the industry-standard approach of auto-generating from a tool.
Source | Reliability | What to pull |
CRM and sales conversations | Highest | Actual questions prospects ask before buying. Pull from call transcripts, email enquiries, live chat logs. |
User research | High | Customer interviews and surveys about search behaviour. Ask: "What did you type into ChatGPT before finding us?" |
SEO keyword data | Medium | Google keywords reframed as conversational queries. "Best B2B agency Singapore" becomes "What are the best B2B marketing agencies in Singapore?" |
Social listening | Medium | Questions from Reddit threads, LinkedIn comments, Quora answers, forum discussions. |

FAQ
AEO stands for Answer Engine Optimisation. It is the practice of optimising your brand's online presence so AI-powered search tools like ChatGPT, Perplexity, and Google AI Overview can discover, cite, and recommend you. Unlike traditional SEO, which focuses on ranking in search engine results pages, AEO focuses on earning visibility within AI-generated answers. Some practitioners also refer to this as generative engine optimisation (GEO).
No. We typically start with Brand Signal (foundation), then Content Signal and Agent Signal (most controllable), then layer in Social Signal and Authority Signal over time. The priority depends on your current strengths and gaps.
AI models update their knowledge at varying intervals. Some results (like Perplexity citations from real-time retrieval) can appear within weeks. Others (like ChatGPT mentions from training data) take longer. The typical engagement sees measurable citation improvements within 60-90 days.
Conversion is not a direct-attribution metric for AEO. The real measurement includes first-time visit capture ("How did you hear about us?"), UTM tracking from AI citation links, overall brand lift in page views and bot crawl activity, and pipeline attribution from leads that mention AI as a discovery channel.
No. SEO is one of the 7 Signals (Search Signal). Pages that rank well on Google are more likely to be sourced by AI systems. Your existing SEO infrastructure is an asset that feeds into your AEO strategy.
