AEO vs SEO vs GEO: What Each Means and How Founders Should Prioritise
SEO (search engine optimization) helps your pages rank in search results. AEO (answer engine optimization) shapes content so it can be used as a direct answer, for example in featured snippets, voice answers and AI overviews. GEO (generative engine optimization) aims to have AI assistants like ChatGPT, Claude, Perplexity and Gemini mention and cite your product. They overlap heavily: crawlable, clear, trustworthy content with good links serves all three. For a small team, do solid SEO first, write answer-shaped pages, then work on consistency and citations for GEO.
New acronyms appear every year in marketing. Three now matter for anyone building a SaaS: SEO, AEO and GEO. The good news is that you do not need three separate strategies. You need one solid foundation and a few extra habits.
This guide explains each term in plain English, shows where they overlap and differ, and gives a priority list you can follow with limited time.
SEO: search engine optimization
Goal: rank your pages in search engines like Google and Bing so people click through.
What it involves:
- Technical basics: fast, crawlable, indexable pages, sitemaps, clean URLs, mobile-friendly design.
- Content that matches what people search for and satisfies them.
- Links from other reputable sites, which signal trust. See what is Domain Rating.
- Titles and descriptions that earn clicks.
Success looks like: rankings, impressions and organic visitors in Google Search Console.
AEO: answer engine optimization
Goal: have your content used as the direct answer to a question, in featured snippets, "People also ask", voice assistants and AI overviews.
What it involves:
- Pages that answer a specific question in the first paragraph.
- Clear structure: question-style headings, short paragraphs, lists and tables.
- FAQ sections with concise answers, marked up with FAQPage structured data.
- Definitions, steps and comparisons written so they can stand alone.
Success looks like: featured snippets, answer boxes and your text quoted in AI overviews, often with a link.
GEO: generative engine optimization
Goal: have AI assistants mention, recommend and cite your product or content when they generate answers.
What it involves:
- Being findable by AI crawlers and live search tools.
- Consistent product information across your site, directories, reviews and articles.
- Being mentioned on the sources assistants cite: well-ranked articles, reviews, community threads.
- Machine-readable summaries such as structured data and an
llms.txtfile.
Success looks like: your product appearing, described accurately, when people ask assistants for tools in your category. Read how to get your SaaS recommended by ChatGPT.
Side-by-side comparison
| SEO | AEO | GEO | |
|---|---|---|---|
| Where it shows | Search result links | Answer boxes, snippets, voice, AI overviews | Answers inside ChatGPT, Claude, Perplexity, Gemini |
| Main unit | Page | Passage that answers a question | Brand and facts across many sources |
| Key levers | Technical health, relevant content, links | Direct answers, structure, FAQ schema | Consistency, citations, crawlability, llms.txt |
| How you measure | Rankings, clicks, impressions | Snippets won, answer appearances | Mentions and accuracy in AI answers, referral traffic from assistants |
| Maturity | Decades of tools and data | Well understood | New and changing fast |
Where they overlap
Most of the work serves all three:
- Crawlable, fast pages let search engines and AI tools read you.
- Clear, honest content that answers real questions ranks, gets quoted and gets cited.
- Reputable links and mentions build trust with search engines and give assistants sources to cite.
- Structured data helps both search features and machines.
If you do good SEO with answer-shaped writing, you are already doing most of AEO and much of GEO.
Where they differ
- SEO cares about the click. AEO and GEO often answer the question without a click, so brand recognition and accuracy matter more than traffic alone.
- GEO cares about your presence across the web, not just your own pages. Consistent listings and third-party mentions carry more weight.
- Measurement is harder for GEO. You often have to ask assistants directly and track referrals from AI tools in analytics.
A priority list for a small SaaS team
- Fix technical SEO: fast pages, sitemap, titles, descriptions, share images, HTTPS, no accidental noindex. Our SaaS launch checklist covers it.
- Write five answer-shaped pages for the questions your buyers ask: the job you solve, the main alternative, pricing, two use cases. Start each with a direct answer and end with an FAQ.
- Add structured data (Organization, SoftwareApplication, FAQPage) and an
llms.txtfile. - Make your brand consistent across your site and 20 to 30 reputable directories and review sites. See best startup directories.
- Earn mentions and links through useful assets, roundups and communities. See backlinks for a new SaaS.
- Check AI answers monthly for your category and note which sources are cited. Aim to be mentioned there.
- Expose your product to agents if relevant, with a public API or MCP server. Read what is MCP for founders.
One page, optimised for all three: a worked example
Suppose you sell a subscription tracking app and want to be found for "how to cancel unused subscriptions". One page can serve SEO, AEO and GEO at once:
| Element | What to write | Serves |
|---|---|---|
| Title | "How to Find and Cancel Unused Subscriptions (2026 Guide)" | SEO |
| First paragraph | A 50 to 70 word direct answer: check bank statements, list recurring charges, cancel in each app's settings, use a tracker for reminders | AEO, GEO |
| Steps | A numbered list: where to look on iPhone, Android, PayPal and your bank | AEO |
| Table | Common services and where their cancel button lives | AEO, GEO |
| Honest tool section | "Tools that help", including yours and one or two alternatives, with prices | GEO |
| FAQ | Four short questions people ask, marked up with FAQPage schema | AEO |
| Sources and date | "Checked November 2026" plus links to official help pages | GEO trust |
| Internal links | To your pricing and feature pages | SEO |
Then promote the page where people ask the question, and get it cited in a roundup or two. That single page can rank, appear as a snippet, and give assistants a clear, trustworthy passage to cite.
Common mistakes
- Writing for machines instead of people. Keyword-stuffed or robotic text fails on all three.
- Hiding the answer. Long introductions before the answer lose snippets and citations.
- Inconsistent facts. Different prices or descriptions across pages confuse assistants.
- Blocking crawlers by accident. A stray noindex or a blanket robots.txt rule can remove you from search and AI answers.
- Chasing new acronyms instead of basics. Most results still come from crawlable pages, clear answers and real mentions.
How IndieDaddy applies this
We built IndieDaddy with all three in mind: server-rendered pages with structured data, product pages with consistent facts, FAQ sections, a public llms.txt, a REST API and an MCP server that AI agents can use. Every product listed gets a clean, crawlable page with its name, description, category and pricing, which helps search engines and assistants describe it consistently.
Frequently asked questions
Is AEO the same as GEO?
They are related but not identical. AEO focuses on being the direct answer to a question in search features and AI overviews. GEO focuses on being mentioned and cited by generative AI assistants. Many people use the terms loosely and interchangeably.
Is SEO dead because of AI search?
No. AI assistants with web search still rely on pages that search engines can find and rank. SEO is the foundation that AEO and GEO build on.
What should a startup focus on first?
Technical SEO and a handful of answer-shaped pages for buyer questions. Then consistency across directories and earning mentions. These steps help all three.
How do I measure GEO?
Ask assistants the questions your buyers ask, track whether your product appears and is described accurately, and watch analytics for referral traffic from AI tools.
Do I need special tools for AEO and GEO?
Not to start. Good writing, clear structure, structured data and consistent listings go a long way. Specialised tracking tools can help later.
