Pillar guides on GEO, AEO, and product AI visibility.
Fifteen long-form guides written for VPs of Ecommerce, VPs of SEO, and the developers who implement their briefs. eCommerce Insights stays neutral on which acronym wins; the guides explain each honestly and cross-link to the relevant solution pages.
Wedge pillars
The two guides eCommerce Insights writes with the most authority, because the phrases themselves are ones eCommerce Insights coined and maintains.
Product AI visibility
The complete guide to measuring and improving how AI engines cite specific products, not just brands. Defines the term, walks through the measurement primitives, and shows how to act on the data.
WEDGESKU-level AEO
The discipline behind eCommerce Insights: optimizing individual PDPs, schema, and metadata so AI engines cite specific SKUs. For SEO leads used to thinking in pages, reframed for the product dimension.
Category pillars
The three guides that define the category's dominant acronyms. Each is written to be a neutral public reference, not a eCommerce Insights pitch — though every guide ends by connecting its ideas to SKU-level practice.
What is GEO
Generative Engine Optimization, the category's umbrella term. What it covers, how it differs from SEO, and which practices actually move the needle as of Q1 2026.
PILLARWhat is AEO
Answer Engine Optimization, eCommerce Insights's default expansion. Includes the "Agent Engine Optimization" alternative that uses and where each framing applies.
PILLARWhat is Agentic Commerce Optimization
ACO, coined by , defined neutrally here. Covers SKU-level product-data readiness for AI shopping agents — including the autonomous purchase case.

PILLARUniversal Commerce Protocol (UCP)
Google's UCP (not Unified Content Protocol) for Shopify brands. Three new Merchant Center attributes, aggressive SLOs, and Shopify Agentic Storefronts.
