AEO vs GEO vs SEO — what each one actually means. Same goal, three layers.
The terms overlap, get used interchangeably, and most explainers muddle them. Here is the precise version: what each optimizes for, where they diverge, and which you should be doing in 2026.

Search Engine Optimization (SEO) optimizes a page to rank in a list of links on a search engine results page. The signal is ranking position; the action is a click through to your site.
Answer Engine Optimization (AEO) optimizes content to be cited inside a single synthesized answer — Google’s AI Overview, featured snippets, voice assistants. The signal is being chosen as the answer; the action is being read or rendered inline, often with no click.
Generative Engine Optimization (GEO) optimizes content to be retrieved, cited, and quoted by generative AI engines — ChatGPT, Claude, Gemini, Perplexity — plus AI Overview. GEO is the superset; AEO is its answer-surface subset. The term was coined by Aggarwal et al. (2023).
The three layers, compared.
All three — they’re layers, not alternatives.
SEO and GEO are not substitutes. AI Overviews are still anchored to the underlying search index: if a page can’t be crawled and ranked, it can’t be cited. The technical fundamentals — clean architecture, fast pages, real authorship, structured data — serve all three layers at once.
What changes between layers is what you write and how you measure it. SEO rewards keyword coverage and links. AEO and GEO reward citable claims: statistics with sources, quotes from named authorities, and a consistent entity layer repeated across enough trusted third-party surfaces that a model treats you as the authority on a concept.
In practice: keep doing technical SEO, and add the AI-citation layer on top. That second layer is exactly what Cite automates — the writing that earns citations, the tracking across all eight surfaces, and the earned-media outreach that builds the third-party density GEO depends on.
