Fundamentals
AEO vs GEO vs SEO: the differences that change what you do
By Arnav Mukherjee, founder of TofuBofu · July 4, 2026
Someone asked me last month whether they needed an AEO strategy, a GEO strategy, or both, because they had been pitched separately on each by two different agencies in the same week.
The short answer is that two of these three acronyms describe the same job, one describes a genuinely different one, and the industry has an incentive to blur which is which. Here is the version that saves you a retainer.
The one-table answer
That is the whole taxonomy. If you want the deep versions, we keep a full reference guide for each: what AEO is and where GEO came from. This post is about the distinctions themselves.
AEO and GEO: the difference is who coined it
AEO came first. It is the broader term, covering featured snippets and voice assistants as well as AI chat, and it emerged from practitioners watching Google answer questions directly instead of listing links.
GEO has a birth certificate, which is unusual in this field. It was coined in "GEO: Generative Engine Optimization" by Aggarwal, Murahari, Rajpurohit, Kalyan, Narasimhan and Deshpande, associated with Princeton and IIT Delhi, submitted to arXiv in November 2023 and accepted to ACM SIGKDD in 2024. They built a benchmark and showed content optimization boosting visibility in generative engine responses by up to 40 percent, while noting in the same abstract that efficacy varies by domain.
That is the entire honest difference: one term has a paper behind it, the other has practice. The tactics they prescribe are the same. I have never seen a task that belongs to one and not the other.
SEO is where the real distinction sits, and we measured it
This is the one worth your attention, because it changes what you do on Monday.
We asked AI engines who the best managed IT providers were across 15 regions, resolved every company named to a real website, and checked the answers against each region's own Clutch directory. Those directories listed 228 firms. The engines named 89 and passed over 139.
Then we added a harder control, the 2026 MSP 501, an independently ranked list of leading firms. Of its 88 ranked firms in those regions, 66 were named by no engine and zero were named by Claude. These are companies that submitted revenue data to be ranked among the best in their industry, and two thirds of them do not exist in the answer a buyer now gets.
Two games, one website
What transfers, and what does not
Technical health transfers completely
Crawlable, parseable, fast, structured. If an engine cannot fetch and read your pages you are not eligible to be retrieved, full stop. Every hour you spent on this counts twice.
Genuinely useful content transfers well
A page that actually answers a question is as useful to an engine assembling an answer as it was to a reader skimming results.
Ranking mechanics do not transfer
Domain authority, keyword placement and link volume are not what an engine consults when choosing which three companies to name. This is the part that surprises good SEO teams, and it is why firms with strong organic performance find themselves absent.
Your own claims about yourself do not transfer
On a results page, your landing page speaks for you. In an answer, other people's pages speak for you. What replaces authority is corroboration: independent sources agreeing on who you are and who you serve.

Because naming a thing is cheaper than measuring it. A new acronym lets an agency sell a new retainer, and lets a tool claim a new category, without anyone having to demonstrate that the underlying work differs. The tell is simple: ask whether a specific task belongs to AEO but not GEO. Nobody has produced one.
Be most careful with AI SEO, which is used for two opposite things. Sometimes it means optimizing to appear in AI answers. Sometimes it means using AI to produce traditional SEO content faster. Those are different products with different prices and one of them is not what you think you are buying.
What to actually do
Pick one term and stop thinking about the vocabulary. We use AEO. Then do the work, which is the same regardless of what you call it: make sure crawlers can read you, get independent sources describing you consistently, put the qualifying facts in plain text, and answer each buying decision on its own page.
And do not let anyone sell you the death of SEO. G2's 2026 buyer research found 51 percent of B2B buyers now begin vendor research on an AI chatbot, up from 29 percent, which means 49 percent still do not. The position we have held since we started has not changed: SEO is the floor and AEO is a distinct layer you can win even when your Google rank does not move.
If you want the depth on either half, the AEO reference guide carries the full mechanism and evidence base, the GEO guide covers the academic origin and what the paper does and does not support, and AI visibility covers how to measure the outcome without fooling yourself.
Frequently asked questions
Are AEO and GEO the same thing?
For practical purposes yes. Both describe getting your company named and cited inside an answer a machine composes. The tactics are identical: be readable to the crawlers, be described consistently, be corroborated by independent sources. The genuine difference is provenance rather than method. AEO is older and broader, covering featured snippets and voice answers as well as AI chat, and grew out of practitioner writing. GEO is newer, points specifically at generative engines, and was coined in an academic paper at ACM SIGKDD in 2024. If a vendor's pitch depends on them being fundamentally different disciplines, that is a marketing position.
Which term should I use, AEO or GEO?
Use whichever your audience searches, and do not spend energy on the distinction. In worldwide search volume 'aeo' is by far the larger term, though it collides with an unrelated clothing retailer, while 'generative engine optimization' is cleaner in intent and still substantial. We use AEO as the primary label and treat GEO as a synonym. What matters far more than the label is whether the person using it can tell you how they measure the outcome.
Is AEO just SEO with a new name?
No, and this is the distinction that actually changes your work. SEO earns a ranked link on a results page. AEO earns a mention inside a composed answer where there is no position one and no page two. We measured the gap: across 15 regions we checked AI engine answers against each region's own directory, and of the 228 firms those directories listed, the engines named 89 and passed over 139. Firms that rank organically routinely fail to appear in the AI answer to the same question. SEO is the floor because crawlability is a precondition. It is not the same game because the answer is decided on corroboration rather than rank.
Does my SEO work transfer to AI search?
Partly, and the part that transfers is the least glamorous part. Technical health transfers directly: if crawlers can fetch and parse your site, you are eligible to be retrieved. Content that genuinely answers a question transfers well. What transfers poorly is everything built around ranking mechanics, because domain authority, keyword placement and link volume are not what an engine consults when deciding which three companies to name. What replaces them is whether independent sources agree about who you are.
What about LLM SEO and AI SEO, are those different again?
LLM SEO is another synonym, usually narrowed to the chat assistants. AI SEO is the one to be careful with, because it gets used for two opposite things: optimizing for AI answers, and using AI tools to do traditional SEO faster. If someone offers you AI SEO, ask which of the two they mean before agreeing to anything. The proliferation of near-identical acronyms is a symptom of a young category where naming the thing is currently cheaper than measuring it.
Should I stop doing SEO and switch to AEO?
No, because they are not substitutes and they fail in different places. Keep the technical foundation, since it is the precondition for both. Keep whatever organic traffic is genuinely producing pipeline. Then add the work that only AEO addresses, which is being corroborated by sources you do not own so that an engine is confident enough to name you. Anyone telling you SEO is dead is selling the replacement, and our own position has not changed: SEO is the floor and AEO is a distinct layer you can win even when your Google rank does not move.
