Web, ecommerce and AI glossary

Short, plain-language definitions of the terms that come up when a company works on its website, its online store or artificial intelligence. Each definition is meant to be understood on its own.

Artificial intelligence agent

A program that uses a language model to complete multi-step tasks, such as finding data, comparing it, writing a result and sending an alert, within defined permissions.

AEO and GEO

Answer engine optimization (AEO) and generative engine optimization (GEO): practices intended to improve the chances that search-enabled assistants find and cite a website.

llms.txt

An optional text file, proposed by the community, that summarizes a site and links to key pages for compatible AI tools.

CMS

Content management system: the panel where a website's text, images, products or articles are edited without touching code.

Headless

An architecture where the visible part of the store (the front end) is separate from the platform that manages products and payments, which allows complete design freedom.

Shop the look

A store format where a campaign photo has interactive hotspots that open each product shown in the image.

Core Web Vitals

Google metrics on a page's loading and interaction experience: load time of the main element (LCP), responsiveness to interaction (INP) and visual stability (CLS).

WCAG contrast

The luminance ratio between text and background. The WCAG guidelines require at least 4.5:1 for normal text and 3:1 for large text at level AA.

UTM

Parameters added to a link (utm_source, utm_medium, utm_campaign) to see in Analytics which campaign a visit came from.

Structured data

Code (usually JSON-LD with schema.org vocabulary) that describes a page's content, such as an organization, a service or an article, so search engines can interpret it.

Price without national taxes

A product's price before VAT and other national indirect taxes are added. In Argentina, the consumer tax transparency regime requires that buyers can see that component.

Sales platform

A site designed from scratch for a brand, without starting from a template, with structure and animations defined by its identity.
