CMS & E-commerce GlossaryCMS & E-commerce Terms A–Z
The core concepts of content management systems and selling online: WordPress, themes and plugins, headless CMSs, product variants and SKUs, product feeds, the cart, checkout and payment gateways.
These entries are written to think about a store's or company site's daily operation, search visibility and security together: what a platform choice trades off, and how technical decisions show up in sales.
Searches term names and alternate names; on category pages also the short definitions.

- CheckoutCheckout is the part of an online store where the contents of the shopping cart become an order: the shopper enters delivery and billing details, picks a shipping option, sees the final total and pays. Because it is the last step before a purchase, form length, surprise costs, speed and error handling have a direct, measurable effect on how many orders are completed.Core · Performance & Analytics · CMS & E-commerce
- CMS (Content Management System)A CMS (content management system) is software that lets people create, edit, review and publish website content such as text, images, pages and menus without writing code. It separates content, stored as structured data in a database, from presentation, defined in templates. Traditional systems like WordPress also render the pages, while a headless CMS only stores content and delivers it through an API.Core · CMS & E-commerce
- CRM (Customer Relationship Management)CRM (customer relationship management) is both the practice of managing a company's interactions with prospects and customers and the software used to do it. A CRM system keeps contacts, conversations, quotes and sales opportunities in one place, so sales, marketing and support teams share the same customer history and managers can see how much business sits at each stage of the sales pipeline.Core · Software · CMS & E-commerce

- Headless CMSA headless CMS is a content management system that provides an editing interface and a content model but does not render the website. Instead, it delivers content as structured data through APIs such as REST or GraphQL to any front end: a website, a mobile app or another channel. The presentation layer, the “head”, is a separate project, often built with a framework like Next.js.Professional · Software · CMS & E-commerce
- Headless CommerceHeadless commerce is an ecommerce architecture in which the customer-facing storefront is decoupled from the commerce engine that manages products, pricing, inventory, carts and orders. The engine exposes its functions through APIs, so a website, a mobile app or an in-store screen can all draw on the same backend while each front end is built and released independently.Advanced · Software · CMS & E-commerce

- Page BuilderA page builder is a visual editing tool for designing web pages by dragging and dropping sections, columns and ready-made components instead of writing code. It is usually installed as a plugin for a content management system such as WordPress or built into a hosted site platform, and it manages layout, styling and content in one interface with a live preview.Core · Web Design · CMS & E-commerce
- Payment GatewayA payment gateway is the service that securely captures card and similar payments on a website or app, routes them to banks and card networks, and reports the result back to the merchant. Card data collection, encrypted transmission, authorisation, voids and refunds happen in this layer, and the integration model chosen largely determines the merchant's security burden and PCI DSS scope.Core · Security & Infrastructure · CMS & E-commerce
- PCI DSSPCI DSS (Payment Card Industry Data Security Standard) is the security standard for any organisation that stores, processes or transmits cardholder data, or can affect its security. It is published by the PCI Security Standards Council, founded by the major card brands. It is not a law, but card networks and acquiring banks enforce it contractually on merchants and service providers. The current version is v4.0.1.Advanced · Security & Infrastructure · CMS & E-commerce
- PermalinkA permalink is the full URL of a post, page or archive in a content management system, intended to stay unchanged for the long term. In systems such as WordPress the permalink format is set by a site-wide setting, and if that structure is changed after publication, every old address has to be connected to its new one with a permanent redirect.Core · SEO · CMS & E-commerce
- Product FeedA product feed is a structured file or API stream that lists a store's products with attributes such as ID, title, description, price, availability, image and landing page URL. Google Merchant Center, marketplaces and comparison sites read the feed to list products and power shopping ads, so it has to be kept in sync with what the store actually shows and sells.Professional · SEO · CMS & E-commerce
- Product SchemaProduct schema is structured data that describes a product's name, image, price, currency, availability and reviews using schema.org's Product and Offer types. Google uses it for two experiences: product snippets for pages where the product can't be bought directly, such as reviews, and merchant listings for pages where it is sold. Valid markup makes a page eligible; it doesn't guarantee display.Professional · SEO · CMS & E-commerce
- Product VariantA product variant is a sellable version of a base product that differs in one or more attributes such as colour, size, capacity or material. Each variant usually has its own SKU, stock level and sometimes its own price. Variants are grouped under a shared parent product, and shoppers pick the version they want on a single product page before adding it to the cart.Core · CMS & E-commerce
S
- ShopifyShopify is a cloud-based (SaaS) ecommerce platform for building and running online stores, bundling hosting, checkout, product and order management into one service. A store's look comes from themes written in the Liquid template language, and extra functionality comes from apps. Shopify manages the servers, security updates and infrastructure, while merchants work through the admin rather than maintaining code on their own servers.Professional · CMS & E-commerce
- Shopping CartA shopping cart is the ecommerce component that holds the products, quantities and selected variants a visitor intends to buy until they proceed to checkout. It handles adding and removing items, changing quantities, applying coupons and showing a subtotal, and its contents can be stored in the browser, in a server-side session or in a database record tied to the customer's account.Core · CMS & E-commerce
- SKU (Stock Keeping Unit)An SKU (stock keeping unit) is an internal code a business assigns to each product, and to each variant of a product, so its inventory, ordering and sales systems can tell items apart. The seller defines SKUs and they only have meaning inside that seller's systems, which is what separates them from global identifiers such as GTINs printed under barcodes.Core · CMS & E-commerce

- Web HostingWeb hosting is the service of running a website's files, database and application code on servers that are permanently connected to the internet, so visitors can reach the site at any time. Hosting models such as shared hosting, VPS, managed hosting and cloud platforms differ in resource isolation, who manages the server, how easily they scale and what they cost. Much of a site's speed, uptime and security depends on this layer.Core · Security & Infrastructure · CMS & E-commerce
- WooCommerceWooCommerce is an open-source ecommerce plugin that adds a product catalog, cart, checkout, order management and inventory to a WordPress site. Developed by Automattic, it runs on WordPress's plugin architecture, and features such as payment gateways, shipping integrations or subscriptions come from extensions. Because the store runs on your own hosting, you keep full control of data and code, along with responsibility for maintenance and security.Professional · CMS & E-commerce
- WordPressWordPress is an open-source content management system written in PHP, using a MySQL or MariaDB database and distributed under the GPL. It began as blogging software and, thanks to its theme and plugin architecture, now runs everything from company websites to online stores. The self-hosted WordPress.org software is not the same thing as WordPress.com, which is a hosted service.Core · CMS & E-commerce
- WordPress PluginA WordPress plugin is a package of PHP-based code that adds new functionality to a WordPress site or changes existing behavior without modifying WordPress core files. Plugins work by attaching to WordPress action and filter hooks; contact forms, SEO fields, caching, ecommerce and custom post types are typically added this way. Every plugin brings new code to the site, and with it a new security and maintenance responsibility.Core · CMS & E-commerce
- WordPress ThemeA WordPress theme is a package of templates, styles and settings that controls how a WordPress site looks and how its pages are laid out. It governs the presentation of content, not the content itself. There are two kinds today: block themes, built from HTML block templates and theme.json and customizable in the Site Editor, and classic themes, built from PHP template files.Core · CMS & E-commerce
