Comparing (SEO) Search Engine Optimisation and (AEO) Answer Engine Optimisation

SEO focuses on page ranking in traditional search engines like Google, while AEO aims to get your content cited in AI-generated answers from platforms like ChatGPT, Copilot, and Google Gemini. Both strategies improve visibility, but they differ in format, audience behaviour, and technical approach.
Note that SEO is likely in decline while AEO is in ascendancy.

Here’s a detailed comparison to help you navigate both worlds:

Implications for you
SEO is about discoverability through links, while AEO is about direct answers and brand visibility without requiring a click.
AEO is rising fast due to the shift in user behaviour – most ChatGPT users treat it like a search engine.
Combining both strategies ensures your content is visible across traditional and AI-powered platforms.
How to Optimise for Both
Use structured content: FAQs, how-to guides, and concise definitions help with AEO.
Maintain depth and authority: Long-form content with backlinks still matters for SEO.
Implement Schema.org markup: This benefits both SEO and AEO by making content machine-readable.
Track new metrics: Monitor AI citations, voice search performance, and featured snippet appearances.
