What to read first

The right entry point depends on where you sit and what you already know.

You have heard "GEO" or "AEO" and want the landscape

Start with What is GEO for the umbrella, then What is AEO for the answer-engine framing. Working in ecommerce specifically, add What is Agentic Commerce Optimization — defined neutrally even though a competitor coined the term. The glossary backs every term with a citable definition.

You know the category and want the SKU-level argument

Read the two pillars: Product AI visibility and SKU-level AEO. Together they explain why brand-level tracking misses ecommerce revenue and what changes when measurement resolves to the SKU. Then baseline your own catalog with the Shopify SKU Visibility Grader.

You are technical and want implementation detail

Stack three reads: Schema for AI search (the truth layer), llms.txt for Shopify (the crawler-guidance layer), and the blog post on Shopify metafields for AI search (the plumbing that keeps both current). The protocol guides — ACP and UCP — cover the agent-checkout layer with primary sources.

You are comparing vendors

Read the relevant comparison page — facts attributed to each vendor's public materials, dated, no trash talk — then the best AI visibility tools for Shopify roundup for the landscape, and finish with why brand-level AI tracking misses your revenue for the design choice this platform makes differently.

Frequently asked questions

Where should a VP of SEO new to AI search start?

Start with the two wedge pillars: the product AI visibility guide and the SKU-level AEO guide. They cover the shift from brand-level to SKU-level thinking, which is the framing most SEO leaders need before tactics. From there, the what-is-GEO and what-is-AEO guides cover the category vocabulary, and the glossary defines every term on its own page.

What is the fastest way to check my catalog's AI visibility?

Run the free Shopify SKU Visibility Grader — it checks a Shopify store's products across AI engines and emails a scored report in about 90 seconds. For a single PDP, the AEO Grader checks any URL in about 30 seconds. Both are free and require no account for the first pass.

How current is this library?

Pages carry explicit date stamps and hedge fast-moving claims with dates ("in pilot as of mid-2026"). Engine-behavior claims state their observation basis, protocol pages describe published specs, and entries are revised as engines and protocols change rather than backdated.

Is there a glossary for the GEO, AEO, and ACO vocabulary?

Yes. The glossary defines the whole category vocabulary neutrally — including the three competing category names (GEO, AEO, ACO), the agentic-commerce protocol layer (ACP, UCP, AP2), and the two terms eCommerce Insights defines canonically: the citation score and the agent-readability score.
