Guide · SEO, AEO & GEO

geo vs seo vs aeo, explained plainly

geo vs seo vs aeo comes down to where you want to show up. SEO (Search Engine Optimisation) is about ranking in the classic list of blue links. AEO (Answer Engine Optimisation) is about being the source an answer engine quotes when it replies directly. GEO (Generative Engine Optimisation) is about being surfaced and recommended inside what a generative engine writes. They are three layers of the same shelf, and they stack.

The short version

  • SEO (Search Engine Optimisation) is ranking in the classic list of links, so a person scanning results clicks through to you.
  • AEO (Answer Engine Optimisation) is being the source an answer engine cites when it replies directly.
  • GEO (Generative Engine Optimisation) is being surfaced and recommended inside what a generative engine writes.
  • They stack rather than compete. The same honest, useful work feeds all three layers.
  • Reddit feeds AEO and GEO in particular, because the engines read it. subding is the awareness layer for that, and it never posts for you.

geo vs seo vs aeo in one line

All three are ways of showing up when someone is looking for something. The difference is where that showing-up happens: in the list of links, in the cited source under an answer, or in the words a generative engine chooses. Same shelf, three heights.

SEO earns the click from the list. AEO earns the citation inside the answer. GEO earns the mention in the reply.

SEO: ranking in the list of links

SEO stands for Search Engine Optimisation, and it is the oldest of the three. The job is to earn a high position in the ranked list a search engine returns, so a person scanning the page clicks through to you. You influence it with useful pages, the words on them, the links pointing at them and the technical health of the site.

  • Content that matches what people are actually searching for
  • Internal and external links that vouch for a page
  • Clean titles, clear structure, and fast, crawlable pages
  • Keywords mapped to real intent, not just volume

SEO has not gone anywhere. The list of links still sits under most AI answers, and a page that ranks well is a page the newer engines are more likely to read. Our guide to AEO vs SEO goes deeper on how the two relate.

AEO: being the answer that gets cited

AEO stands for Answer Engine Optimisation. An answer engine gives a direct reply instead of only a list of links, and it names the sources it leaned on. AEO is the work of being one of those cited sources. Picture an assistant like ChatGPT, Claude or Perplexity, or Google’s AI overviews, summarising a topic and linking out to a handful of pages. AEO aims to be one of them.

  • Clear, well-structured answers a machine can lift a clean line from
  • Content organised around the real questions people ask
  • Enough authority that an engine trusts the page to quote it

Our explainer on what AEO is covers the mechanics in full.

GEO: being named in generative results

GEO stands for Generative Engine Optimisation. A generative engine writes an answer in its own words, and along the way it names tools, brands and products it considers relevant. GEO is the work of being one of the names it reaches for. Where AEO is about being cited as a source, GEO is about being recommended inside the generated text, whether or not a link is attached.

  • Being present, in a good light, across the sources a model reads
  • A consensus of real people naming you for the job
  • Coverage the model has seen often enough to repeat

There is no dashboard to set your position and no form to submit. You can read more on the pattern in our guide to LLM SEO and on AI visibility.

The three compared

The same page, thread or brand can win on all three at once. Read down each column to see what changes between them, and across each row to see how the same dimension plays out for SEO, AEO and GEO.

Notice how far the levers overlap. Most of the work you would do for one quietly helps the other two.

Where they overlap

The three overlap more than the acronyms suggest. They all reward the same underlying thing: being genuinely useful and easy to find on the open web. A page that ranks is easier to cite, and a brand that is cited and discussed everywhere is easier to recommend.

  • All three reward clear, useful, well-structured content
  • All three read the open web, so one strong page can help every layer
  • None of them can be bought, faked or guaranteed for long

Do you need all three?

For most brands, yes, because they stack rather than compete. You do not pick one. You rank in the links, you become a citeable source, and you build the reputation that gets you named in generated answers. The same honest work feeds all three layers, so the sensible order is to build up rather than choose.

  • Start with SEO. Ranking pages are the base the other two build on.
  • Layer AEO. Make your best answers clean, structured and easy to quote.
  • Earn GEO over time. Build genuine presence where your category is discussed.

How Reddit feeds AEO and GEO

Reddit feeds AEO and GEO in particular, and it is worth being specific about how. Reddit content-licensing deals signed in 2024 wired its threads into the pipelines behind Google’s AI and other assistants, and Reddit is one of the most-cited domains in AI answers. For questions like ‘best tool for X’, a lot of what an engine cites or recommends traces back to what real people said in a thread.

→ Join it while it’s live

That gives AEO and GEO a shared, practical route: be genuinely present in the recommendation threads for your category, under your own name, while they are live. A real, disclosed, useful reply is the kind of thing an engine will happily cite or repeat later.

The engines read Reddit. Being in the thread, honestly and early, is where AEO and GEO meet.

subding is the awareness layer for that route. It reads posts and comments for Reddit and, on a fixed five-minute check, pings you in Slack, Discord, email or a webhook the moment your keyword comes up. It never posts, and it cannot promise a citation or a recommendation. We surface the thread; a person on your team writes the reply. More on the specifics in our guide to Reddit GEO, and on the tool itself in the Reddit monitoring tool overview.

Questions, answered straight

What do SEO, AEO and GEO stand for?

SEO is Search Engine Optimisation, AEO is Answer Engine Optimisation, and GEO is Generative Engine Optimisation. SEO is about ranking in the list of links, AEO is about being cited as a source in a direct answer, and GEO is about being named inside a generative engine’s written reply.

What is the difference between geo vs seo vs aeo?

geo vs seo vs aeo comes down to where you show up. SEO (Search Engine Optimisation) ranks you in the classic list of blue links. AEO (Answer Engine Optimisation) makes you the source an answer engine quotes when it replies directly. GEO (Generative Engine Optimisation) gets you surfaced and recommended inside what a generative engine writes. They stack rather than compete.

Is AEO just the new SEO?

Not quite. AEO builds on SEO rather than replacing it. Good SEO still gets your page ranked and read, and that same page is what an answer engine goes on to cite. Treat AEO as an extra layer aimed at the answer box, not a swap for the fundamentals.

Do I have to choose between SEO, AEO and GEO?

No. They stack. The same honest, useful content that ranks well tends to get cited and recommended too. Most brands work on all three at once, starting from a solid SEO base.

How does Reddit affect AEO and GEO?

Reddit is one of the most-cited sources in AI answers, and content deals from 2024 put its threads into the systems behind Google’s AI and other assistants. For recommendation questions, being genuinely present in the right Reddit threads is a practical way to influence both what gets cited and what gets named.

Can subding get my brand cited or recommended?

No, and be wary of anyone who promises it. subding is read-and-notify only. It tells you the moment a relevant Reddit thread appears so a human on your team can join it. We never post, comment or upvote, and we cannot guarantee a citation or a mention.

Which of the three should I start with?

Start with SEO, because ranked, well-structured pages are the foundation the other two build on. Layer AEO by making your best answers clean and easy to quote, then earn GEO over time through genuine presence where your category is discussed.

Be in the thread before the AI reads it

SEO, AEO and GEO all reward the same thing: being genuinely present where people look. On Reddit, that means catching the right thread while it is live. That is the part subding handles.
