What is GEO? Generative Engine Optimisation
GEO is generative engine optimisation: the work of getting your brand written into the answers that generative AI tools produce, ChatGPT, Claude, Perplexity and Google’s AI among them. Instead of chasing a ranked link, you aim to be one of the sources the model draws on when it writes its reply.
The short version
- GEO stands for generative engine optimisation: earning a place inside an AI-written answer, not just a ranked page.
- It matters because a growing share of searches end with a generated answer the reader never scrolls past.
- Generative engines favour clear, well-sourced, widely-agreed content, and they lean on Reddit threads heavily.
- You practise it by being genuinely present and quotable in the places these models read, then letting it compound.
- Nobody can promise a spot in an answer. subding catches the live Reddit thread so a person on your side can join it.
Why GEO matters now
Ask a modern assistant a question and you rarely get ten links back. You get a written answer, assembled from sources the model trusts, with maybe a handful of citations tucked underneath. The reader reads the reply and moves on. For a lot of questions, that reply is now the whole search.
That changes what visibility means. Ranking well still helps, but if the generated answer names three tools and none of them is yours, a strong position on the second page barely registers. GEO is the response to that shift: the practice of making sure your brand is one of the names the model reaches for.
The goal moves from a click on your link to a mention inside the answer someone reads instead.
It sits on top of your wider search work rather than replacing it, and it targets the moment a reader may never see a list of links at all. We map how the pieces fit in our overview of AI visibility.
GEO versus classic SEO
GEO and SEO share plumbing: clear structure, credible sourcing, content that actually answers the question. Where they part ways is the finish line, and it helps to see the split plainly.
| Classic SEO | GEO | |
|---|---|---|
| What you want | A ranked page. | A named mention inside the generated answer. |
| The reward | A click to your site. | Your brand quoted, even with no click. |
| Where it plays out | A search results page. | ChatGPT, Claude, Perplexity and Google’s AI. |
| Main lever | On-page work and backlinks. | Being a trusted, quotable source models already read. |
Same foundations, different prize. Solid SEO still feeds GEO, but a ranking and a citation are not the same outcome.
If you want the wider comparison, including answer engine optimisation, we lay all three out in GEO, SEO and AEO compared.
What generative engines read
A generative engine can only mention what it has been trained on or can retrieve, so it leans on content it can trust and lift cleanly. A few kinds of source turn up in answers far more than the rest.
- Plainly structured pages. Clear headings and direct statements a model can quote without second-guessing your meaning.
- Self-contained claims. A sentence that stands on its own is far easier to cite than one that only makes sense in a long paragraph.
- Agreement across sources. When several credible places say the same thing, the model repeats it with more confidence.
- Reddit discussions. Candid, first-hand recommendations from real people are exactly what these tools reach for on “what should I use” questions.
That last point does a lot of work. Reddit sits among the most-cited domains in AI answers, and its content deals with major AI companies wired those threads into the systems that now write recommendations. A live thread asking for the best option in your category is a place your name can end up in tomorrow’s answer.

The snag is timing. Recommendation threads earn their answers in the first day or so, then quieten down. Find one a week later and the picks are already written, and none of them is you. That is why catching the thread early matters, and why a Reddit monitoring tool belongs in the GEO kit.
How to do GEO
There is no field where you type in your desired answer. GEO is earned, and it comes down to a few steady moves plus the patience to let them add up.
- 1
Answer the real questions clearly
Work out what your buyers actually ask an assistant, then write the plainest, most honest answer to each. Clear, quotable pages are the ones models lift from.
- 2
Show up where the models read
A generative engine can only cite what it has seen. That means being genuinely present in the pages and Reddit threads it draws on, especially the recommendation and alternatives discussions.
- 3
Be useful before you are promotional
The content that gets quoted answers the question first. When you mention your own product, say who you are. A helpful, disclosed contribution earns trust; an advert dressed as advice gets skipped.
- 4
Let consensus build
One page or one comment rarely shifts an answer. A consistent, useful presence across the right sources reads you into the picture over months. Think steady, not a single push.
For the specific case of getting named when someone asks an assistant for a recommendation, we go step by step in LLM SEO, and the broader plan lives in AI search optimization.
GEO, AEO and the acronym soup
You will meet a few labels for what is largely the same effort. GEO talks about generative engines writing answers. AEO, answer engine optimisation, talks about being the source those answers cite. Some people use them interchangeably, and honestly the work barely changes between them.
If the naming matters for a plan or a pitch, we untangle it in what is AEO and AEO versus SEO. For everything else, pick a term and get on with being the clear, credible answer.
The honest limits
GEO earns its place, but it is not a lever you pull for guaranteed results, and anyone selling certainty is selling you something. Keep these in view before you spend on it.
What GEO can’t do
- You do not set the answer. You influence what a model writes; you cannot dictate it, and there is no form to fill in to be listed.
- Mentions come and go. A citation you earn this month can fade as the models retrain and the web shifts beneath them.
- It is slow work. Being read into the consensus takes months of steady, useful presence, not one campaign.
- Tools surface; people act. subding tells you when a relevant Reddit thread appears. It never posts, comments or joins on your behalf, and it never will.
For the record, subding will not write a reply, cast a vote or run an agent that takes part for you. The awareness is ours to hand over. The genuine, disclosed, human contribution is yours to make.
Questions, answered straight
What is GEO?
GEO is generative engine optimisation: the work of getting your brand written into the answers that generative AI tools produce, ChatGPT, Claude, Perplexity and Google’s AI among them. Rather than ranking a link, you aim to be one of the sources the model uses when it composes its reply.
How is GEO different from SEO?
Classic SEO earns a ranked page and a click. GEO earns a place inside the generated answer, where your brand is named even if the reader never visits a site. The groundwork overlaps, but the target is a citation in the reply, not a position on a results page.
Does Reddit help with GEO?
A great deal. Reddit is one of the most-quoted sources in AI answers, and for recommendation questions the model often echoes what real people said in a thread. Being genuinely present in those discussions is one of the most direct ways to influence what a generative engine writes.
Can I guarantee my brand appears in an AI answer?
No, and treat any promise otherwise with suspicion. The systems change weekly and nobody sets what they output. You can improve the odds by being quotable, credible and present in the sources they read; that is the honest ceiling.
Is GEO the same as AEO?
They point at the same problem from slightly different angles. GEO talks about generative engines writing answers; AEO talks about answer engines citing sources. In day-to-day work the moves are nearly identical, which is why we set them beside each other in a separate piece.
How long does GEO take to work?
Months, not days. A model reads you into the consensus over time, as you show up usefully across the sources it trusts. There is no submit button and no overnight win, so plan for steady presence rather than a single campaign.
Get written into the answer
You can’t order a generative engine to name you. What works is being useful, in your own name, in the Reddit discussions it draws on, and reaching them before they set. Catching those early is where subding earns its keep.
