Two Different Games
SEO and AEO are often discussed as if one is replacing the other. That's the wrong frame. They're complementary practices targeting different user behaviours — and brands that excel at both will have a significant advantage.
What is AEO?
Answer Engine Optimization (AEO) is the practice of optimising your content and brand presence to appear in direct answer responses from AI engines — including ChatGPT, Perplexity, Google AI Overviews, Gemini, and Copilot.
The key distinction: AEO targets answers, not links. When a user asks an AI a question, the goal is to be mentioned in the response — not just to be a result they might click.
What is SEO?
Search Engine Optimization is the established practice of improving your visibility in traditional search engine results pages. Rank higher for relevant queries, earn more clicks, drive more traffic.
How They Differ
Intent stage
- SEO: Best for users who are researching, comparing, or are near purchase
- AEO: Best for users who want a quick, direct recommendation — often at the top of the funnel
Measurement
- SEO: Rankings, click-through rates, organic traffic
- AEO: Citation rate, mention frequency, share of voice in AI responses
Content format
- SEO: Keyword-optimised pages, meta tags, structured data
- AEO: Authoritative long-form content, brand facts, third-party validation
Timeline
- SEO: Weeks to months to see ranking movement
- AEO: AI models update their knowledge continuously; improvements can show up faster
Why You Need Both
Here's the counterintuitive truth: strong SEO helps AEO.
Many AI platforms — especially those doing real-time retrieval like Perplexity — pull heavily from search indexes. Brands with strong backlink profiles and topical authority in Google tend to appear more in AI responses.
But SEO alone isn't enough. AI answer engines introduce new ranking signals that traditional SEO doesn't capture: how your brand is discussed in community forums, how frequently you're cited by other authoritative sources, whether your content directly and clearly answers common questions.
Building an Integrated Strategy
The most effective approach treats SEO and AEO as a unified practice:
- 1Build topical authority — comprehensive content that establishes your brand as the expert in your category
- 2Earn third-party mentions — press, reviews, community discussion
- 3Structure your brand facts — clear, consistent, machine-readable information about what you do and who you serve
- 4Measure both — track keyword rankings *and* AI citation rates
