SEO vs AEO vs GEO: how to get found when customers ask AI instead of Google

For twenty years, being found online meant one thing: ranking on Google. That era isn't over — but it's no longer the whole story. Your next customer might find you through a classic search result, a featured snippet read aloud by a voice assistant, or a recommendation written by ChatGPT or Perplexity. Three channels, three disciplines.

SEO: being ranked

Search Engine Optimization is the foundation everything else builds on. Google still drives the majority of discovery, and its fundamentals haven't changed: useful content that answers real questions, descriptive titles and headings, fast pages, mobile-friendly layouts, and links from reputable sites. If your SEO is weak, AEO and GEO can't save you — both feed on the same signals.

AEO: being the answer

Answer Engine Optimization targets the moments when a search engine answers the question directly — featured snippets, "People Also Ask" boxes, voice assistant replies. To win those positions:

• Phrase headings as the actual questions customers ask.
• Answer the question in the first sentence or two below the heading — then elaborate.
• Use structured formats: lists, tables, step-by-step instructions.
• Add FAQ schema markup so machines can parse your questions and answers cleanly.

GEO: being cited

Generative Engine Optimization is the newest discipline: making your business findable, understandable and quotable by AI systems — ChatGPT, Perplexity, Google's AI Overviews, Bing Copilot. AI engines don't return ten blue links; they synthesise an answer and cite a handful of sources. Being one of those sources is the new first page. What helps:

• Clear, factual, well-structured content. AI models quote passages that stand alone — self-contained paragraphs that make one clear point.
• Entity clarity. Spell out your business name, your services and your service area in plain sentences. Schema markup (Organization, Service, LocalBusiness) reinforces this.
• Crawlability. Your robots.txt must allow AI crawlers; a growing convention is an llms.txt file that gives AI systems a guided tour of your site.
• Consistency across the web. AI cross-references. Your name, services and location should match everywhere they appear.

The practical takeaway

You don't need three separate strategies. One well-built site serves all three channels: solid technical SEO as the base, question-and-answer content structure for AEO, and clear entity information plus schema for GEO. The businesses that set this up now will compound their advantage while competitors are still asking what GEO stands for.
