Answer engine optimization (AEO) is the practice of structuring your content and product data so AI answer engines — ChatGPT, Gemini, Perplexity, and Google's AI Overviews — cite and recommend you directly in their answers, rather than just linking to your site.
Search is shifting from a list of links to a single synthesized answer. For ecommerce, the unit that has to win isn't a blog post — it's the SKU.
Ask an assistant what to buy, and you're either in the answer or invisible. There is no page two.
AEO vs GEO vs SEO
Classic
SEO
Optimizes to rank a page among ten blue links.
Generative
GEO
Generative engine optimization — optimizes to be included in an AI-generated answer.
Answer
AEO
The broader practice of becoming the cited answer across answer engines.
The labels overlap and people use them interchangeably. The shared shift is the one that matters: from earning a click to being the answer.
Why ecommerce AEO is different
Most AEO advice is written for content and B2B brand mentions — get cited in the answer to an informational question. Commerce is harder, because the answer is a purchase decision and the catalog is shared.
An AEO checklist for a DTC store
01
Complete structured data
Product, FAQPage, and Organization schema on every relevant page — with attributes beyond price and availability.
02
Ship an llms.txt
Give models a clean, authoritative summary of who you are and what you sell.
03
Earn reviews and brand mentions
Third-party corroboration is what answer engines trust most.
04
Write for information gain
Pages that add genuinely new, proprietary detail get cited; pages that restate competitors don't.
05
Stay crawlable to AI bots
Allow the on-demand citation crawlers (ChatGPT-User, PerplexityBot, Claude-User) in robots.txt.
06
Measure LLM visibility
Everything above is a hypothesis until you track whether you're actually cited and ranked.
AEO tools and measuring LLM visibility
AEO tools split into two camps:
Mentions
Visibility trackers
Profound, Otterly, Peec and similar — count how often your brand is mentioned across AI answers.
Revenue
Commerce tools
Grade how individual SKUs rank across ChatGPT, Gemini, and Perplexity, audit who holds each slot in Shopify's catalog, and attribute agent-driven orders. Notice is built for this.
Notice is built for the commerce side — per-SKU rank tracking, slot-ownership audits, and agent-order attribution — because for a DTC brand, mentions are vanity; the SKU that gets bought is the number that matters.
Measuring your AI visibility starts with one question: where do your SKUs actually rank?
Answer engine optimization (AEO) is the practice of structuring your content and product data so AI answer engines like ChatGPT, Gemini, Perplexity, and Google's AI Overviews cite and recommend you directly in their answers, rather than just linking to your site. For ecommerce that means optimizing product data so an agent recommends and can buy your SKU, not just describing your brand.
What's the difference between AEO, GEO, and SEO?
SEO optimizes to rank a page in a list of blue links. GEO — generative engine optimization — optimizes to be included in an AI-generated answer. AEO — answer engine optimization — is the broader practice of becoming the cited answer across answer engines. The terms overlap heavily and are often used interchangeably; the shared shift is from earning a click to being the answer.
What are the best answer engine optimization tools?
AEO tools fall into two groups. Visibility trackers (Profound, Otterly, Peec, and similar) measure how often your brand is mentioned across AI answers. Commerce-specific tools go further for merchants: they grade how individual SKUs rank across ChatGPT, Gemini, and Perplexity, audit who holds each product slot in Shopify's catalog, and attribute agent-driven orders. Notice is built for that commerce use case. The best tool depends on whether you're optimizing brand mentions or product revenue.
How do I measure my LLM visibility?
Pick the prompts that drive your category, run them across ChatGPT, Gemini, and Perplexity on a schedule, and record whether you're mentioned, in what position, against which competitors, and with what sentiment — down to the SKU. Tracking this over time is what turns AEO from guesswork into a measurable channel.
