Shopify Glossary of Terms.

An abandoned cart happens when a customer adds products to their basket but leaves the store before completing checkout. For Shopify brands, abandoned carts are an important part of email and retention strategy. A well-built abandoned cart flow can remind customers what they left behind, answer last-minute concerns and encourage them to complete their purchase.

Agentic Storefronts are Shopify’s way of making products available to buy directly inside AI chat platforms, so customers can discover and purchase without visiting the store first.More broadly, agentic commerce describes a shift where AI agents and assistants can support more of the buying journey. Instead of a customer only browsing a website manually, AI systems may help them discover products, compare options, check availability and move closer to purchase.For Shopify brands, this makes product data, structured content, feeds, merchandising and technical SEO even more important. Your store still matters, but it may no longer be the only place where product discovery starts.

Shopify Analytics gives merchants a view of store performance, including sales, sessions, conversion rate, average order value (AOV), customer behaviour, customer lifetime value (CLTV), product performance and more. It is one of the most useful areas of Shopify Admin for understanding what is happening across your store. Analytics can help teams see which products are selling, where traffic is coming from and where customers may be dropping off.

API stands for Application Programming Interface, software that allows two or more computer programmes to communicate with one another. An API acts as an intermediary layer to send information back and forth between a website or app and a user.

A Shopify app is an add-on that extends the functionality of a Shopify store. Apps can support areas such as reviews, loyalty, subscriptions, product filtering, delivery, returns, email marketing, analytics, merchandising and more.

Average order value is the average amount a customer spends each time they place an order. You calculate it by dividing total revenue by the number of orders over the same period. For example, if your store takes £5,000 from 100 orders, your AOV is £50. For eCommerce brands, increasing AOV can help grow revenue without needing more traffic. Product bundles, free delivery thresholds, upsells and relevant product recommendations can all encourage larger baskets. A considered Shopify CRO strategy helps you test these approaches and understand what adds value for your customers and your business.

B2B stands for Business to Business. In Shopify, B2B usually refers to selling products from one business to another, rather than directly to consumers. For brands that sell wholesale, trade or corporate orders, Shopify B2B can reduce the need for separate platforms or heavily customised workarounds.

A blended storefront allows a merchant to run DTC and B2B buying experiences from the same Shopify store. Instead of managing two separate stores, brands can serve different customer types from one setup, using Shopify features such as companies, catalogues, customer accounts, pricing and market-specific experiences. This can be useful for brands that sell to both consumers and wholesale customers, but it needs careful planning around UX, pricing, permissions and operations.

A CTA is a prompt that encourages a customer to take a specific action. Examples include “Shop now”, “Add to basket”, “Book a demo”, “Get in touch” or “Download the guide”. Strong CTAs are clear, relevant and easy to find. They help customers understand what to do next.

Shopify Checkout is the checkout experience used by Shopify stores. It is one of the most important parts of the buying journey because it is where customers enter their details, choose delivery, select payment and complete their order. Shopify Checkout is known for speed, familiarity and trust, but it still needs to be configured properly around payment options, delivery, discounts, tracking and customer expectations.

Checkout Extensibility is Shopify’s modern way of customising checkout. Rather than editing checkout code directly, merchants and developers use Shopify’s approved extension framework to add functionality in a safer, more upgradeable way. For Shopify Plus merchants, Checkout Extensibility is especially important because checkout is one of the most commercially sensitive parts of the customer journey.

A collection is a group of products within a Shopify store. Collections help customers browse and discover products more easily. For example, a fashion brand might have collections for jackets, dresses, trainers or new arrivals. Collections can be created manually or automatically using rules based on product tags, titles, prices, vendors or other product data.

Companies are a Shopify B2B feature used to manage business customers. A company can have locations, buyers, permissions, payment terms and customer-specific settings. This helps B2B merchants manage wholesale accounts, trade customers and business buyers in a more structured way.

Conversion rate is the percentage of store sessions that result in an order. For example, if 100 people visit your Shopify store and 3 place an order, your conversion rate is 3%. Conversion rate is one of the most important metrics in eCommerce, but it should not be looked at in isolation. Traffic quality, product availability, pricing, UX, trust, shipping, returns and payment options can all influence how well a store converts.

Conversion Rate Optimisation is the process of improving a store so more visitors take a valuable action, such as adding to cart, reaching checkout or placing an order. CRO can include UX improvements, product page changes, navigation updates, merchandising changes, checkout improvements, testing and better use of customer insight.

Call to Action. An instruction in the form of a shape, button or text, or even an image that encourages visitors to perform an action, such as a Shop Now button. CTAs can be included on emails, social media platforms, and websites.

Customer lifetime value is the total revenue a customer is expected to generate throughout their relationship with your brand. It looks beyond the first purchase to account for repeat orders and long-term spending. CLTV helps inform customer acquisition budgets and retention strategies. Understanding which customers are likely to return and spend more helps your team prioritise valuable customer segments, personalise email marketing and build relationships that support sustainable growth.

The Shopify Customiser, also known as the theme editor, is where merchants can edit the look, layout and content of their Shopify store. It allows teams to update sections, blocks, templates, homepage layouts, product pages, collection pages and other parts of the storefront without editing code directly.

It describes brands that sell directly to their end customers, rather than only selling through retailers, wholesalers or marketplaces. Shopify is often used by DTC brands because it gives them more control over their store, customer experience, data, marketing, checkout and operations.

Shopify Editions is Shopify’s regular product release cycle. Every six months, Shopify brings together its latest updates, features and platform changes under one Editions release. Each Edition brings together new features across areas such as AI, storefronts, checkout, B2B, POS, operations, marketing and development. For merchants, Editions is useful because it gives a clearer view of where Shopify is heading and which new tools might be relevant to their business. Not every update needs immediate action. The value comes from understanding which features could support your store, your team and your growth plans.

ERP stands for Enterprise Resource Planning. An ERP system helps businesses manage core operations such as inventory, finance, purchasing, order management, supply chain and reporting. For larger Shopify merchants, ERP integration can be critical. It helps connect the storefront with the operational systems that keep the business moving.

First-party data is information a business collects directly from its own customers and channels. For Shopify brands, this includes purchase history, browsing behaviour on your store, email and SMS engagement, customer account details and in-store activity through Shopify POS. Because it comes straight from your own customer relationships, it is usually the most accurate and reliable data a business has. First-party data powers much of modern eCommerce marketing. It supports customer segmentation, personalised email flows, product recommendations and more relevant advertising. Platforms such as Klaviyo use this data to help brands send the right message at the right time.

Flow can refer to two common things in eCommerce. In Shopify, Shopify Flow is an automation tool that helps merchants automate tasks across their store and connected apps. In email marketing, a flow usually refers to an automated sequence of emails or SMS messages triggered by customer behaviour, such as signing up, abandoning a cart or making a purchase.

The frontend is the part of a website that customers see and interact with. A strong frontend is not only about how the store looks. It also needs to be easy to use, fast, accessible and commercially effective.

Fulfilment is the process of preparing, packing and shipping orders to customers. For Shopify merchants, fulfilment may be handled in-house, through a warehouse, through a third-party logistics provider or through a mix of different locations. Strong fulfilment processes help protect the customer experience after purchase. Slow dispatch, unclear tracking or poor stock accuracy can quickly damage trust.

Shopify Functions allow developers to customise parts of Shopify’s backend logic in a controlled and scalable way. Functions replace Shopify Scripts and can support custom logic for discounts, delivery options, payment methods, checkout validation and more. For merchants, Shopify Functions are usually most relevant when standard settings are not flexible enough for a specific commercial or operational requirement.

A payment gateway allows you to accept online payments, such as credit card transactions, securely on your Shopify store.

Gift cards let customers buy store credit to spend themselves or give to someone else. Shopify supports digital gift cards online and physical gift cards through Shopify POS, with balances tracked in one place. For Shopify brands, gift cards can support seasonal campaigns, bring in new customers and encourage repeat visits.

Headless commerce separates the frontend of a store from the backend commerce platform. For Shopify merchants, this means Shopify can still manage products, orders, checkout and commerce operations, while the customer-facing storefront is built using a separate frontend framework. Headless can be powerful, but it is not right for every brand. It usually needs more technical planning, development resource and long-term maintenance.

The homepage is usually the main entry point of a Shopify store. It often introduces the brand, highlights key products or collections, promotes campaigns and helps customers find their way into the buying journey. A good homepage should not try to do everything. It should guide customers clearly towards the most useful next step.

Hydrogen is Shopify’s framework for building custom headless storefronts. It is designed for brands and developers who need more control over the frontend experience while still using Shopify for commerce infrastructure. Hydrogen is usually more relevant for complex, high-growth or technically ambitious brands than for merchants who can achieve what they need with a well-built Shopify theme.

HTML stands for Hypertext Markup Language. It is one of the core building blocks of the web and is used to structure content on web pages. Shopify themes use HTML alongside Liquid, CSS and JavaScript to create the storefront experience.

Inventory is the stock a merchant has available to sell. In Shopify, inventory is tracked by product variant and by location, such as a warehouse, a retail store or a third-party fulfilment centre. Accurate inventory helps prevent overselling, supports better merchandising and keeps online and in-store stock in line. For growing merchants, inventory often needs to sync with ERP, warehouse or POS systems so every channel shows the right stock level.

Journey mapping is the process of understanding the steps a customer takes before, during and after buying from a store. It helps eCommerce teams identify friction, missed opportunities and areas where the store could better support customers.

A Klarna integration allows Shopify merchants to offer Klarna payment options, such as buy now, pay later, at checkout. Payment flexibility can support conversion, but it should be implemented carefully and presented clearly so customers understand their options.

A Klaviyo integration connects Shopify with Klaviyo, allowing merchants to use customer, product and order data for email and SMS marketing. This can support abandoned cart flows, welcome series, post-purchase journeys, customer segmentation, product recommendations and retention activity.

Liquid is Shopify’s template language. It is used in Shopify themes to load dynamic store content, such as products, collections, customer information, cart data and settings. For merchants, Liquid is usually handled by developers, but it plays a major role in how Shopify themes are built and customised.

A list is a group of opted-in customer profiles, usually used for email and SMS marketing. In platforms such as Klaviyo, lists are often used to manage subscribers. Lists are different from segments, which are dynamic groups based on behaviour or rules.

llms.txt is a file format designed to help large language models and AI systems understand website content more clearly. For Shopify merchants, llms.txt connects to the wider shift towards AI visibility and agentic commerce. As customers use AI tools to research, compare and discover products, stores need to make their content and product data easier for machines to understand. Shopify has started adding llms.txt to stores, which makes it an important new area for Shopify SEO and AI discoverability.

Managed Markets is Shopify’s solution for simplifying international selling. It helps merchants manage parts of cross-border commerce such as duties, taxes, international shipping, localisation and compliance. This can be useful for brands that want to expand internationally without managing every operational detail manually.

Shopify Markets lets businesses tailor the shopping experience for different countries, B2B customers, retail locations and sales channels from one Shopify admin. Depending on your plan and market type, you can customise currencies, languages, domains, pricing, product availability and theme content. This helps customers see the products and prices relevant to them, while giving your team a simpler way to manage international expansion and wholesale growth.

Metafields allow merchants to add custom information to Shopify resources such as products, collections, customers, orders and pages. For example, a product might need extra fields for materials, ingredients, care instructions, technical specifications, icons or delivery information. Metafields are especially useful for brands with complex products, richer product storytelling or specific operational requirements.

Metaobjects are a way to create and manage custom structured content in Shopify. They are useful when merchants need repeatable content that goes beyond standard pages, products or collections. Examples might include brand ambassadors, store locations, ingredient profiles, size guides, FAQs or product feature blocks. Metaobjects can help teams manage richer content in a more consistent and scalable way.

A migration is the process of moving an eCommerce store from one platform to another. For example, a brand may migrate from Magento, WooCommerce, BigCommerce or a custom platform to Shopify or Shopify Plus. A successful migration is not just about moving products and pages. It also needs careful planning around SEO, data, integrations, redirects, customer accounts, fulfilment, reporting and the wider business operation.

Navigation is how customers move around a Shopify store. This includes menus, category links, collection links, footer links, filters, breadcrumbs and search. Good navigation helps customers find what they need quickly. For larger Shopify stores, navigation is also closely linked to merchandising, SEO and conversion rate.

Order management is the process of receiving, processing, fulfilling, tracking and managing customer orders. In Shopify, order management connects to payments, fulfilment, inventory, refunds, returns, customer communication and reporting. For growing merchants, order management often needs to connect with ERP, warehouse or fulfilment systems.

Page views measure how many times pages on your Shopify store have been viewed. They can help teams understand which products, collections, blogs or landing pages are attracting attention. Page views are useful, but they should be considered alongside other metrics such as sessions, conversion rate, add-to-cart rate and revenue.

A payment gateway allows a Shopify store to accept payments securely. Shopify Payments is Shopify’s own gateway, but merchants may also use providers such as PayPal, Stripe, Klarna or other region-specific payment options. The right setup can influence checkout trust, payment success rates and customer convenience.

A payment processor handles the transaction between the customer’s payment method and the merchant’s bank account. The processor works behind the scenes to authorise, process and settle payments.

Point of Sale, or POS, refers to the systems used to sell products in person. Shopify POS allows merchants to connect retail stores, pop-ups, events and physical selling environments with their Shopify store. This means online and in-store sales, inventory and customer data can work together more clearly. For omnichannel retailers, Shopify POS can support a more unified view of the customer and the business.

A product description is the written content that explains what a product is, what it does and why a customer might want to buy it. Good product descriptions should be useful, clear and specific. They should support customers, search engines and, increasingly, AI systems that need to understand the product.

A product page is the page where an individual product is displayed. It usually includes images, product descriptions, price, variants, availability, reviews, delivery information, returns messaging and add-to-cart functionality. A strong product page gives customers the information they need to make a confident buying decision.

Product variants are different versions of the same product. Common variants include size, colour, material, scent, pack size or style. Managing variants properly is important for inventory accuracy, merchandising, product feeds, search, filtering and customer experience.

In Shopify projects, QA is the process of testing a store before changes go live. This can include testing design accuracy, links, forms, responsiveness, checkout, integrations, tracking, accessibility and performance. Good QA helps reduce bugs, protect customer experience and avoid costly issues after launch.

A URL redirect sends visitors and search engines from an old web address to a new one. On Shopify, these are 301 (permanent) redirects. You can add them individually in Shopify Admin or import them in bulk using a CSV file. When changing a product, collection or page URL, you can also create a redirect from the previous address. Redirects are an essential part of a Shopify migration, helping customers reach the right pages and protecting the SEO value built up on your existing website. Planning and testing a full redirect map before launch helps prevent broken links, preserve search visibility and keep customers moving towards a purchase.

Responsive design means a website adapts properly across different screen sizes, including mobile, tablet and desktop. For Shopify stores, responsive design is essential because customers may browse on one device and buy on another. A store needs to be easy to use wherever the customer is.

Shopify Rollouts is a native Shopify feature that allows merchants to schedule, stage and test storefront changes. Rollouts can be used to prepare theme updates, launch changes gradually or run controlled experiments. For eligible plans, merchants can split traffic between the current experience and a rollout version. This gives brands a safer way to test changes, launch campaigns and make storefront improvements without relying entirely on third-party testing tools.

A sales channel is a place where a merchant sells products. In Shopify, this can include the online store, Shopify POS, Shop, social channels, marketplaces and other connected selling environments. Managing sales channels properly helps keep product data, inventory and orders more connected.

A segment is a group of customers who meet specific rules or conditions. For example, a segment might include customers who bought in the last 90 days, customers who spent over a certain amount or subscribers who clicked a recent email. Segments are useful for more targeted marketing, reporting and customer analysis.

A session is a period of activity from a visitor on your Shopify store. One visitor can have multiple sessions over time. Shopify uses sessions to help merchants understand traffic volume and customer behaviour. Sessions are useful, but they should be looked at alongside conversion rate, revenue, traffic source and customer intent.

Shopify Catalog is part of Shopify’s wider agentic commerce direction. It is designed to help structure and surface product data so AI agents and shopping experiences can understand products more accurately. This makes product information, taxonomy, availability, variants, pricing and structured content increasingly important. For merchants, the takeaway is clear: product data is no longer just a merchandising or SEO asset. It is becoming part of how products are discovered by AI-led shopping journeys.

Shopify Plus is Shopify’s enterprise-level plan. It is designed for larger, more complex or faster-growing businesses that need more control, scalability, automation, support and advanced features. Shopify Plus can be useful for brands with high order volume, multiple stores, international operations, B2B requirements, retail complexity or more advanced checkout and integration needs.

Shop Pay is Shopify’s accelerated checkout, allowing customers to save their email address, delivery information and payment details for faster purchases. For brands on Shopify, Shop Pay reduces the need to fill out checkout forms, particularly on mobile. Combined with clear delivery costs and returns information, it can help reduce checkout friction and give customers more confidence to complete their purchase.

Sidekick is Shopify’s AI-enabled commerce assistant. It works inside Shopify Admin and can help merchants get guidance, generate content, understand store data and complete tasks using everyday language. Sidekick is part of Shopify’s wider move towards AI-supported commerce operations. For merchants, it can reduce friction in day-to-day admin, but it works best when teams already have clear goals, clean data and a proper understanding of what they are trying to achieve.

Shopify SimGym is an AI storefront testing app that uses simulated shoppers to browse products, explore collections and add items to their basket. It helps brands review a theme or compare their live store with a draft version, spotting potential obstacles in the shopping journey before publishing changes. SimGym can give merchants an early steer on where to focus Shopify conversion rate optimisation (CRO). Its findings should be checked against real customer data and A/B testing. Our guide explores how SimGym’s AI shoppers can support better storefront decisions.

Tags are labels that can be added to products, customers, orders, blog posts and other Shopify resources. They help merchants organise information, create rules, support collections, trigger workflows and manage data more efficiently. Tags can be useful, but they need governance. Too many inconsistent tags can make a store harder to manage over time.

A Shopify theme controls the look, feel and structure of a Shopify storefront. Themes include templates, sections, Liquid, CSS, JavaScript, images and settings that shape what customers see on screen. A theme should support both brand experience and commercial performance. It needs to look good, load quickly, work on mobile and make it easy for customers to buy.

Third-party data is information collected by companies that have no direct relationship with your customers. It is usually gathered from many websites and sources, then combined and sold to advertisers. It has traditionally been used to target new audiences based on interests, demographics or online behaviour. However, privacy regulation, browser restrictions and stricter consent requirements have made third-party data less reliable and harder to use. For Shopify brands, this has made first-party and zero-party data more valuable. Data that customers share directly with your business is more accurate, more privacy-friendly and easier to act on.

UI stands for User Interface. It refers to the visual and interactive elements of a website, such as buttons, typography, colours, layout, forms, menus and spacing. For Shopify stores, good UI helps customers move through the site clearly and confidently.

UCP stands for Universal Commerce Protocol. It is connected to the development of agentic commerce, where AI agents need a structured way to discover products, manage carts and support commerce interactions. UCP is part of the bigger shift towards AI-led shopping journeys on Shopify. Merchants do not need to understand every technical detail, but they do need to understand that structured product data and platform readiness are becoming more important.

UX describes the overall experience a customer has when using a website, including navigation, usability, content, speed, product discovery, checkout and post-purchase journeys. For Shopify brands, UX is not just a design concern. It directly affects conversion, customer trust, repeat purchase and brand perception.

Variant-level publishing lets you control which individual Shopify product variants, such as sizes, colours or pack quantities, appear across sales channels and product catalogues. You can hide or publish specific options without deleting variants or creating duplicate products. This makes it easier to tailor product ranges to different customers. You could offer an exclusive colour online or reserve bulk packs for B2B buyers, while keeping everything managed under one product.

A Visual Technical Architecture Map or Tech Stack is a diagram that shows how a business’s systems connect. For Shopify merchants, this might include Shopify, ERP, warehouse systems, email marketing, reviews, loyalty, analytics, payment providers, fulfilment tools and customer service platforms. It helps teams understand the full tech stack, identify dependencies and spot where data or processes may be breaking down.

Tools and data analysis techniques used to track and measure website traffic, user behaviour, and conversion rates on your Shopify store.

A webhook is a way for one system to send real-time information to another system when something happens. For example, Shopify might send a webhook when an order is created, a product is updated or a customer account changes. Webhooks are often used in integrations, automation and custom workflows.

A wishlist is a feature that allows customers to save products they are interested in and return to them later. Wishlists can support consideration, repeat visits and email marketing, especially for brands with higher consideration products or large catalogues.

A Xero integration connects Shopify with Xero accounting software. This can help merchants manage financial data, orders, revenue, tax and reconciliation more efficiently. As with any finance integration, accuracy matters. The setup should be planned carefully so data moves between systems in the right way.

An XML sitemap is a file that helps search engines discover and understand the pages on a website. Shopify automatically creates sitemap files for stores, including links to products, collections, pages and blog content. For SEO, XML sitemaps help search engines crawl important URLs more efficiently, but they work best when the site structure, internal linking and content quality are strong too.

Zero-party data is information customers intentionally share with your business, such as their interests, shopping preferences or product needs. You can collect it through product quizzes, surveys, preference centres and sign-up forms.
