SEO vs AEO vs GEO: What's the Difference and Where to Start

Business owners keep hearing about AEO and GEO, and a fair question follows: does the SEO we’ve been doing still matter, or do we need to switch to something else?

The short answer: you don’t have to choose. The three aren’t rivals. They’re layers. SEO sits at the bottom, and if that layer is weak, nothing above it holds. Here’s how they differ, point by point, and where to start.

The 3-line summary

SEO (Search Engine Optimization) gets your pages ranked in search results so people click through.
AEO (Answer Engine Optimization) gets your content lifted as the answer: Featured Snippets, Google AI Overviews, voice assistant replies.
GEO (Generative Engine Optimization) gets AI tools like ChatGPT, Gemini and Perplexity to mention or cite your brand when they summarize an answer.

SEO: the foundation you still can’t skip

Google’s AI Overviews and most AI search tools still pull from pages that are indexed and visible in search. If Google can’t find your site, or it’s so slow that crawlers miss content, great writing won’t help. AI never gets to see it.

Get these right first:

All important pages indexed (check Google Search Console)
Speed and mobile usability in good shape
Each page has one clear topic that matches what people search for
Internal links that lead to your service pages

The fundamentals in depth: What is SEO: the definitive guide.

AEO: write so one paragraph answers the question

AEO is mostly about how you write. Answer-extraction systems favor text that answers a question directly and briefly, sitting right under a heading phrased as that question.

What works:

Use headings that are real customer questions, e.g. “How long does it take to build a website?”
Answer fully in the first 2–3 sentences under the heading, then expand.
Use tables, lists and numbered steps. They’re easy to lift and display.
Add schema that matches the content: FAQPage, HowTo, Article.

GEO: make AI know your brand

GEO differs because it doesn’t live only on your site. When AI decides which business to suggest, it draws on many sources: your site, reviews, articles that mention you, business profiles. If those sources disagree, or nobody mentions you at all, AI has little reason to recommend you.

What helps:

Business details (name, services, area, contact) identical everywhere: website, Google Business Profile, social accounts
Content that states clear facts: what you do, for whom, and how you’re different
Real, verifiable work and case studies
Mentions from outside sources: reviews, interviews, sites in your industry
Letting AI crawlers in, plus an llms.txt file that summarizes your site

Which should a small business do first?

Our recommended order is SEO → AEO → GEO, because each step builds on the one before.

First month: fix the SEO basics. Clear technical issues, get core service pages indexed and complete.
Next: reshape content for AEO. Add FAQ sections to service pages, phrase headings as questions, add schema.
Ongoing: build GEO signals. Collect reviews, publish case studies, keep business info consistent across every channel.

Nothing in this order is wasted. Content written to answer questions clearly also helps SEO. Reviews and real case studies built for GEO also help visitors decide.

Common misconceptions

“SEO is dead, do GEO instead.” No. Most AI tools still rely on content they can find through search. SEO remains the front door.

“AEO will kill my clicks.” Some simple questions end at the answer. Complex or purchase-stage questions still get clicks, and being the quoted answer builds brand recall.

“There’s a tool that gets you into AI answers instantly.” Nobody controls what AI says. You can only raise your odds with information that is clear, accurate and trustworthy.

How to tell if it’s working

SEO: clicks and impressions in Google Search Console, month over month
AEO: which questions start winning Featured Snippets or appearing in AI Overviews (check from a logged-out browser)
GEO: keep a list of questions your customers would ask, put them to ChatGPT, Gemini and Perplexity every month, and note whether your brand comes up

FAQ

Do I need to hire for SEO, AEO and GEO separately? Not usually. Most of the work overlaps. Someone who does SEO well and understands content structure and schema covers AEO too. GEO depends on real input from the business owner, such as reviews and past work.

What’s the difference between AEO and GEO? AEO cares about which text on your site gets quoted. GEO cares about whether your brand is mentioned or recommended by AI, even if it doesn’t quote your site directly.

Can a small site get cited by AI? Yes, especially for niche or local questions that big sites don’t answer in detail. Specific, factual content has a real chance of being picked.

How long does it take? SEO basics often show movement within weeks to a few months, depending on the site and competition. GEO is a long-term build. We don’t guarantee rankings or citations, but we do our best on everything within our control.

Bottom line

SEO gets you found. AEO gets you chosen as the answer. GEO gets AI to know and trust your brand. Build the foundation first, then layer up.
