Commerce & AI glossary

The AI-commerce vocabulary Cartwright is built around.

AEO (Answer Engine Optimization)

Structuring content so AI answer engines (ChatGPT, Perplexity, Google AI Overviews) can extract and quote it directly — answer-first copy, self-contained FAQs, and Schema.org markup.

GEO (Generative Engine Optimization)

Getting your brand and products surfaced and recommended inside AI-generated answers — the AI-era successor to SEO. Cartwright measures AI-citation share over time.

MCP (Model Context Protocol)

An open protocol that lets AI agents discover and call an application’s tools over a typed interface. Cartwright ships an MCP server so agents can run shop operations natively.

ACP (Agentic Commerce Protocol)

Endpoints that let an external buying agent create a checkout session and complete a purchase on a user’s behalf — first-class agent customers, same auth path as humans.

A2A (Agent-to-Agent)

A buyer agent negotiating and transacting with a seller agent — price negotiation, escrow verification, and a signed Agent Card for discovery.

Presentment currency

The currency shown to and charged to the customer at checkout, which may differ from the store’s base accounting currency. Cartwright snapshots it plus the FX rate on the order.

Structured data (JSON-LD)

Machine-readable Schema.org markup embedded in a page so search engines and AI crawlers understand it without executing JavaScript. Cartwright ships it server-side on every citable page.

llms.txt

A plain-text/Markdown file at a site’s root giving AI agents a curated, token-efficient index of the site and what they are permitted to do with it.
