AEO vs GEO vs SEO: what’s the difference for an online store?

AEO vs GEO vs SEO: what’s the difference for an online store?
Short answer

SEO gets your pages ranked in search results so shoppers click through. AEO (answer engine optimisation) shapes content so search engines and assistants can lift it as a direct answer, like a featured snippet or a voice reply. GEO (generative engine optimisation) gets your brand mentioned and cited inside AI-generated answers from ChatGPT, Perplexity, Gemini and Google AI Overviews. For an online store, all three share one foundation, so run them as one plan.

Key takeaways
  • SEO earns clicks, AEO earns answers, GEO earns mentions and citations in AI-generated responses.
  • All three rest on the same foundation: pages that are crawlable, clearly structured and trusted by other sites.
  • AI traffic to retail sites is still small but growing fast, and it converts well.
  • Collections and buying guides do the heaviest lifting for all three on an online store.
  • Measure separately: rankings and clicks for SEO, answer features for AEO, prompt-level mentions for GEO.

What are SEO, AEO and GEO?

They’re three goals on the same search journey. The labels overlap, and agencies use them loosely, but this is the distinction that matters for an online store:

Why do AEO and GEO matter for eCommerce now?

Because shoppers now ask assistants what to buy, and the numbers grew quickly through 2025:

800M
Weekly ChatGPT users (OpenAI, October 2025)
2B
Monthly users of Google’s AI Overviews (Alphabet, July 2025)
+693%
AI-referred visits to US retail sites, holiday 2025 vs 2024 (Adobe)

Adobe also found AI-referred shoppers converted 31% more than visitors from other sources over the 2025 holidays. At the same time, AI answers take clicks away from ordinary results: Pew Research found people clicked a regular result on 8% of searches with an AI summary, against 15% without one.

So the job has changed. Ranking still matters, but being the brand the answer names matters more each year.

How do SEO, AEO and GEO overlap?

Mostly, they share one foundation. An AI engine can’t cite a page it can’t crawl, and it won’t quote a page that buries the answer. Google’s AI Overviews draw on Google’s own index, so weak SEO usually means weak AI visibility too.

Where they differ is emphasis. AEO is about formatting answers so they can be lifted cleanly. GEO adds a third-party layer: AI engines weigh reviews, comparisons and niche publications heavily, so what other sites say about you matters as much as your own pages.

SEO, AEO and GEO sit on one foundation: crawlable pages, clear structure and trust. Each then adds its own layer.

Which store pages matter most for SEO, AEO and GEO?

On a Shopify or WooCommerce store, a few page types carry almost all of the work:

PageSEO roleAEO roleGEO role
Collections and categoriesRank for category searchesAnswer-first intro and FAQsClear range facts AI can repeat
Product pagesRank for model searchesSpecs in plain sentencesConsistent price, stock and reviews
Buying guidesRank for “best X” searchesDirect picks and reasonsThe pages AI cites for recommendations
Comparison pagesRank for “X vs Y”A one-line verdictOften quoted word for word
FAQ and help pagesLong-tail questionsOne question, one answerSupporting facts

Start with your top collections. They’re where the three overlap most, which is why our Shopify collection page SEO guide covers AI answers too.

How do you run SEO, AEO and GEO as one plan?

Don’t split them into three projects. Work in this order, because each step makes the next one count for more:

  1. Foundations (SEO): crawlable URLs, one URL per product, fast templates, clean indexing.
  2. Structure (AEO): answer-first intros, one question per heading, FAQs and comparison tables.
  3. Facts (AEO + GEO): Product, Offer, Review and FAQ structured data; consistent names and prices everywhere.
  4. Reputation (GEO): mentions and reviews on the niche sites AI engines already cite in your category.
  5. Measurement (all three): rankings, answer features and a fixed set of buying prompts, checked monthly.

FAQs

Is GEO replacing SEO?
No. Google’s AI Overviews are built on its search index, and ChatGPT and Perplexity cite pages they can find and crawl. Good SEO is the entry ticket for GEO, not something it replaces.
Is AEO the same as GEO?
They overlap and people use the terms loosely. AEO usually means formatting content so it can be shown as a direct answer; GEO means earning mentions and citations inside AI-generated answers, which also depends on what other sites say about you.
Do I need an llms.txt file?
It’s a proposed standard, not a requirement, and it doesn’t replace crawlable pages. It’s cheap to add, so we include one on client sites, but it won’t make up for weak content or blocked crawlers.
How long does GEO take to show results?
Crawlability and structured data fixes can show within weeks. Mentions on other sites take longer to earn. Our clients’ AI visibility grew steadily over five months once the work started.
