What agentic commerce terms should every Shopify founder know?
Agentic commerce comes with a pile of new words, and most of them describe one idea: software is starting to shop on a person's behalf. Here are seven terms worth knowing, explained the way I would explain them to a founder over coffee.
1. Agentic commerce
This is the whole shift. An AI agent browses, compares, and completes purchases for a shopper instead of the shopper doing it by hand. Your store has to be ready for a machine buyer, not just a human one.
2. AEO
Answer engine optimization. It is the work of making your store readable and quotable so AI assistants recommend you, the way SEO made you findable on Google. Different engine, different rules.
3. Structured data
Machine-readable markup that tells a model exactly what your product is. Product schema is the version that matters most for commerce.
4. Product feed
The structured file of all your products and their attributes. A clean, complete feed is what lets an assistant read and match your catalog. Holes in it get you skipped.
5. Programmatic checkout
A checkout path a machine can complete without human gestures. Shopify's checkout developer tools support it, so an agent can finish a purchase on your store.
6. Citation
When an assistant names your store or links your page as a source in its answer. Perplexity shows these openly. A citation is proof you crossed from invisible to referenced.
7. Grounding
When a model pulls live information from the web to answer instead of guessing from memory. Grounding is why readable, current data on your store matters so much.
Here's the bottom line: you do not need to master every term. You need to know whether an agent can read, trust, and buy from your store today. These seven are the vocabulary for answering that.
