SEO vs AEO vs GEO: What Each One Means in 2026
SEO, AEO, and GEO are three names for one job: SEO gets your pages ranked in Google, AEO gets them quoted as the direct answer, and GEO gets your brand cited inside AI-written replies. Google’s own guide calls all of it “still SEO.” Start with SEO, since the other two pull from pages that already rank.
Key Points
- SEO earns a ranked page, AEO earns the answer box, and GEO earns a citation inside an AI-written answer.
- Google’s guide to its AI features says optimizing for them is “still SEO.”
- GEO began as a Princeton and IIT Delhi research paper, where adding statistics, quotes, and sources raised visibility by up to 40%.
- The order that works for a store is SEO first, then answer-first writing, then brand mentions.
What Do SEO, AEO, and GEO Mean?
SEO, AEO, and GEO mean search engine optimization, answer engine optimization, and generative engine optimization. Each label names a different spot where your page can show up, and they arrived in that order. SEO came with Google, AEO came with answer boxes, and GEO came with chatbots.
SEO: Search Engine Optimization
SEO is the work of getting your pages to rank in Google’s regular results so shoppers click through to your store. It covers the keywords your pages target, how fast and crawlable the site is, how pages link to each other, and which other sites link to you.
On a Shopify store, that mostly means collection pages built around the words shoppers type, product pages with unique copy, a blog that answers pre-purchase questions, and a menu that links all of it together. None of it is glamorous, and all of it compounds.
Nothing about the newer labels replaces that base, which is also my answer on whether AI search will replace Google. If Google can’t crawl a collection page, no answer box or chatbot will ever see it.
AEO: Answer Engine Optimization
AEO is the work of getting your page picked as the direct answer to a question. It started with featured snippets, the boxed answer Google lifts from one page, and now covers People Also Ask, voice assistants, and AI Overviews.
A quick example shows the difference. A page that ranks third for “how long does sunscreen last” is an SEO win. The same page quoted in the box above the first result, so the shopper gets the answer without scrolling, is an AEO win.
You can’t mark a page up to force any of those. Google’s documentation says featured snippets are chosen automatically by its systems, so the only lever you hold is how clearly the page answers. I go deeper on the label itself in what AEO is.
GEO: Generative Engine Optimization
GEO is the work of getting your brand named or cited when an AI tool writes its own answer. The targets are ChatGPT, Gemini, Perplexity, Copilot, and Google’s AI Mode, and the audience is large: OpenAI reported 900 million weekly ChatGPT users in February 2026.
The term has a real origin. It comes from a research paper by a Princeton-led team, presented at the KDD conference in 2024, that tested which page edits got sources quoted more often in AI answers. My guide to what GEO is walks through the edits that tested best.
SEO vs AEO vs GEO at a Glance
SEO vs AEO vs GEO at a glance is one table: what you win, where it shows, what the page needs, and what you count.
| Compare | SEO | AEO | GEO |
|---|---|---|---|
| What you win | A ranked page and a click | The boxed or spoken answer | A mention or citation in an AI reply |
| Where it shows | Google and Bing results | Featured snippets, People Also Ask, AI Overviews | ChatGPT, Gemini, Perplexity, Copilot, AI Mode |
| What the page needs | Keyword targeting, crawlable structure, links | The answer in the first sentence under each heading | Numbers, quotes, sources, and a brand other sites mention |
| What you count | Rankings, clicks, revenue | Snippets held, AI Overview citations | Brand mentions, AI referral visits |
How Much Do SEO, AEO, and GEO Overlap?
SEO, AEO, and GEO overlap on most of the work, and Google says so directly in its guide to generative AI features:
From Google Search’s perspective, optimizing for generative AI search is optimizing for the search experience, and thus still SEO.
That line comes from Google’s guide to optimizing for generative AI features, which names AEO and GEO and files both under SEO. The same guide says you don’t need new machine readable files, AI text files, or special markup to appear.
In practice, that shared base covers a lot of ground: pages Google can crawl, one clear topic per page, content written from real experience, and text a machine can read without running scripts. Every one of those helps you rank, helps you get quoted, and helps you get cited.
But the overlap is not total once you leave Google. Ahrefs ran 15,000 prompts through ChatGPT, Gemini, and Copilot and found only 12% of the URLs they cited ranked in Google’s top 10 for the same question. A page-one ranking gets you into the pool, and it doesn’t guarantee the chatbot picks you.
So I treat the labels as one job with three scoreboards. The base is the same site and the same pages, and only the last 20% of the work changes by label. Whether GEO earns its own name at all is a fair fight, and I take a side in is GEO just SEO with a new name.
What Changes on Your Pages for Each One
What changes on your pages is small for each one: SEO sets the keyword and the structure, AEO moves the answer to the top of each section, and GEO adds numbers, quotes, and sources.
The Princeton paper measured that last part. Across its 10,000-query benchmark, adding statistics, quotations, and cited sources lifted a page’s visibility in AI answers by up to 40%.
Here is the order I work through on a single page:
- Pick one keyword for the page and put it in the title tag, H1, and URL. That’s SEO.
- Write each H2 as a question a shopper would ask, and answer it in the first sentence underneath. That’s AEO.
- Back every claim with a number and link the source. That’s GEO.
- Make each section readable on its own, with the product or topic named instead of “it” or “this.” That helps all three.
- Link the page to its collection and to two related posts. That’s SEO again, and it’s how the other two find the page.
One thing you can skip is chopping pages into tiny pieces. Google’s guide says there is no requirement to break content into small chunks for AI to understand it. A full page with clear sections does better than ten thin ones, and my AEO checklist covers the rest of the on-page list.
Which One Should Your Store Do First?
Your store should do SEO first, then AEO, then GEO. AI answers are built from pages that search engines have already crawled and indexed, so the order follows the plumbing. Do SEO first, since AEO and GEO have nothing to quote until your pages are indexed.
The case for not stopping at SEO got stronger in 2025. Semrush tracked more than 10 million keywords and found AI Overviews on 15.69% of them by November, after a July peak of 24.61%. In that same data, the share of AI Overview keywords with buying intent grew from about 10% in January to about 32% in October.
That shift means AI answers are moving off pure how-to questions and onto the searches that lead to a sale. A store that only tracks blue-link rankings is missing part of the picture on its money keywords.
For a store starting from zero, here is how I’d split the first six months. Months one and two go to crawl fixes, collection pages, and metadata, which is the core of my Shopify SEO services.
After that, months three and four go to answer-first blog content. Months five and six add outreach for brand mentions, and I lay out the full contrast between the old and new playbooks in AI SEO vs traditional SEO.
How Do You Measure SEO, AEO, and GEO?
You measure SEO with rankings and organic revenue, AEO with snippets and AI Overview citations, and GEO with brand mentions and AI referral visits. SEO is the only one of the three with a complete report, so the other two take some manual work.
| Label | Main number | Where you get it |
|---|---|---|
| SEO | Clicks and revenue from organic search | Search Console, GA4, Shopify |
| AEO | Questions where your page is the quoted answer | Spot checks in Google |
| GEO | How often AI tools name your brand | Monthly prompts in ChatGPT, Gemini, and Perplexity |
| GEO | Visits and sales from AI tools | GA4 referrals from chatgpt.com and others |
The last row is the one I trust most, since it ends in dollars. On Exclusive Beauty Club, revenue from Google organic rose 166% and revenue from ChatGPT rose 2,234% between April 2025 and April 2026, which I break down in the Exclusive Beauty Club case study. Both numbers came from the same set of pages.
For the two middle rows, keep a simple sheet. List your ten most important questions, check them on the first of each month, and mark who holds the answer box and who the chatbots name. A year of those monthly checks tells you more about AEO and GEO than any one-time audit.
If you haven’t set up the AI side yet, it takes about two minutes. My guide to tracking AI traffic in GA4 has the one regex you need.
Common Questions About the Three Labels
The common questions about SEO, AEO, and GEO are whether the labels mean the same thing and whether each one needs its own vendor. The short answer to both is no.
Is AEO the Same as GEO?
No, AEO is not the same as GEO, but the two overlap enough that most stores should run them as one project. AEO aims at the answer box and GEO aims at the AI-written reply, and the same answer-first page serves both. I compare them side by side in GEO vs AEO.
Is AEO Just Featured Snippets?
No, AEO is not just featured snippets anymore. Snippets are where AEO started, and the same habits now feed AI Overviews, People Also Ask, and voice answers. The longer version is in is AEO just featured snippets.
What About AIO, LLMO, and AI SEO?
AIO, LLMO, and AI SEO are more names for the same GEO work. AIO stands for AI optimization, LLMO for large language model optimization, and AI SEO is the plain-spoken version of both. If a proposal uses one of them, read it as GEO and check the deliverables, not the acronym.
Do You Need a Separate Agency for Each One?
No, you don’t need a separate agency for SEO, AEO, and GEO. One person who understands your store can run all three from the same content plan, and splitting them across vendors usually means paying three times for overlapping work. That’s why my AI search services sit on top of the SEO work instead of beside it.
If an agency quotes AEO and GEO as two line items on top of SEO, ask what is different about the deliverables.
What to Do This Week
You can start on all three labels with the pages you already have:
- Open your top five pages by revenue and check that the first sentence under each heading answers the heading.
- Ask ChatGPT and Google the three questions your customers ask most, and note which brands get named.
- Look at Search Console for questions where you rank on page two, since those are the fastest answer-box wins.
- If you’d like that done for you, my AI search services cover AEO and GEO, or you can book a call and I’ll show you which of the three is costing your store the most.
