SEO, AEO and GEO are often confused. All three help you become visible when someone searches, but the landscape, signals and evidence of success differ. Here is the framework we use internally to decide where to invest.
SEO (Search Engine Optimization). The goal is to appear in organic results on Google and Bing. The levers: clean indexing, a strong response to search intent, solid on-page optimization, mobile performance, internal linking and authority (backlinks). Measurement: rankings, clicks and impressions in Google Search Console.
AEO (Answer Engine Optimization). The goal is to be the answer — a Google featured snippet, People Also Ask, Google AI Overviews and, more broadly, any answer engine. The levers: self-contained paragraphs of 40 to 60 words immediately after an H2 phrased as a question, structured data (FAQPage, HowTo, Article), inline definitions, scannable lists and tables. Measurement: citations, position 0 and presence in AI Overviews.
GEO (Generative Engine Optimization). The goal is to be cited by generative engines: ChatGPT, Perplexity, Claude, Gemini and Mistral. The levers: entity authority (consistent brand mentions across the open web), coverage of entities present in the SERP top 10, numerical data with sources, a stated methodology, visible update dates and Person/Organization schema with sameAs. Measurement: citation presence in generated answers across a panel of target prompts.
The major change from traditional SEO: a backlink remains a vote of authority for Google, but a citation in an LLM answer rests on something else. The engine does not refer users to you because another site linked to you — it cites you because your page contains a precise, sourced, dated fact attributable to a recognized entity. Factual structure carries more weight than PageRank.
Shared technical requirements. Server rendering (AI crawlers often ignore JavaScript executed on the client), semantic HTML, reasonable speed, robots.txt allowing GPTBot, ClaudeBot, PerplexityBot and Google-Extended if visibility is the goal, rich schema.org markup, llms.txt at the root and a clean sitemap.
Strategic overlap. The technical foundation (indexing, performance, schema and HTML semantics) serves all three. Content, however, takes different forms: one topic can produce an in-depth SEO page (broad intent, authority), a compact AEO answer (a citable snippet) and a GEO entity profile (numerical facts, sources, a dated update). The same editorial material, three formats.
Where to start. First, the SEO foundations — without clean indexing, neither AEO nor GEO works. Then AEO on pages that answer explicit questions. GEO in parallel on topics where the brand needs to exist as a reference source. This sequence avoids chasing AI while running a site that Google itself cannot read.
The common mistake: treating AEO and GEO as a separate channel managed by a tool. They are editorial and technical disciplines connected to the same content. Agencies selling ‘GEO autopilot’ are selling nothing of substance — what can be measured is real citations on target prompts, not a tool score.
