AEO vs GEO vs SEO — what actually changes in 2026

Three acronyms, one shift

SEO is what you already know: optimise pages so a search engine ranks them.

AEO (Answer Engine Optimization) focuses on getting your brand named inside an AI-generated answer. The unit of value is a mention, not a click.

GEO (Generative Engine Optimization) is the broader practice of shaping how generative engines synthesise answers about your category — including which sources they cite, how often, and with what sentiment.

What stays the same

• Authoritative content still wins. The engines are reading the same web you optimised for.
• E-E-A-T signals (experience, expertise, authoritativeness, trust) still matter — arguably more.
• Structured data still helps engines parse your pages reliably.

What changes

• Citations beat clicks. Earning a citation in a high-volume answer is worth more than a top-10 SERP ranking on a low-CTR query.
• Source diversity matters. Engines pull from review sites, forums, YouTube, and niche category sites. SEO's "win one link" mindset doesn't cover the citation surface.
• Confidence labels are non-optional. AI visibility changes more day-to-day than SERP rank. Without a confidence label every shift gets over-read.

Where to start

Measure first. Pick the 20 prompts that actually drive your buying decisions and track them across all four engines. The implementation pack should fall out of the gaps.
