The website builder vocabulary, in plain words

Builder marketing leans hard on a handful of words that sound simple but quietly decide what you pay. A plan that looks cheap can still leave you on a builder subdomain, with ads on your pages and a cut taken from every sale. This glossary defines the terms that actually affect your decision, written for a buyer rather than a vendor, and flags the ones that map to cost.

Use it alongside our how to choose and pricing guides, where these terms do the real work of separating tools.

Key terms

Glossary of website builder terms that matter

Website builder

Software that lets you create and publish a site without writing code, using templates and a visual editor. Most builders bundle hosting, security, and an optional domain into one subscription.

Template or theme

A pre designed starting layout you customize with your own text, images, and colors. The depth of the template library, and how freely you can change one, is a major difference between builders.

Drag and drop editor

A visual editor where you place and move elements directly on the page. Some builders let you drop an element anywhere on a canvas, while others snap content into preset sections to keep layouts tidy.

WYSIWYG

Short for what you see is what you get. The editor shows the page as it will appear when published, so you design the live result rather than code and preview separately.

Responsive design

Layouts that adapt to phone, tablet, and desktop screens. Most builders generate a responsive site automatically, though how much control you have over the mobile view varies a lot.

CMS

A content management system for handling structured content such as blog posts or product collections from one place. Builders like Webflow and WordPress.com lean on a CMS for content heavy sites.

Hosting

The servers that store your site and serve it to visitors. With a website builder, hosting is almost always bundled into the subscription rather than bought separately.

Custom domain

Your own address, such as yourname.com, rather than a builder branded one. Connecting a custom domain almost always requires a paid plan; many builders include the domain free for the first year.

Subdomain

A builder branded address, such as yoursite.wixsite.com, given on free plans. It signals a trial or hobby site, which is why a custom domain is usually the first reason buyers upgrade. Verified as of June 2026.

SSL certificate

The security that encrypts traffic between your site and visitors and turns on the padlock and https in the browser. Most builders include it at no extra cost on every plan.

Ecommerce

The tools to sell products or services online, including a cart, checkout, and order management. Selling is typically gated to a commerce or business plan rather than the entry tier.

Transaction fee

A cut the builder takes from each sale, on top of the card processing rate. It often drops to zero on higher commerce plans. Squarespace, for example, charges a fee on its entry Basic commerce plan and waives it on Core and above. Verified as of June 2026; check the vendor for current pricing.

Payment processing rate

The fee charged by the payment provider, such as Stripe, PayPal, or Square, to handle a card payment. It is separate from any builder transaction fee and applies on every plan.

SEO tools

The controls that help search engines understand your pages: editable titles and meta descriptions, clean URLs, sitemaps, and redirects. Basic SEO is common everywhere; finer control often sits on higher plans.

App market and integrations

Add ons that extend a builder, from booking and email to analytics. Some are free, many are paid third party subscriptions, so the headline plan price is rarely the full cost.

Custom code and export

The ability to add your own HTML, CSS, or JavaScript, or to export the site to host elsewhere. Most closed builders limit this; it matters most if you fear lock in or want a developer to extend the site.

Common questions
What is a website builder?

A website builder is software that lets you create and publish a site without writing code, using templates and a visual editor. Most builders bundle hosting and an optional domain, so one subscription covers the editor, the servers, and the security certificate.

Do I need to know how to code to use a website builder?

No. The point of a website builder is that you assemble pages visually rather than write HTML or CSS. Some builders, such as Webflow, expose more of the underlying structure and reward technical users, while others, such as Wix or Squarespace, hide it almost entirely.

Which website builder terms most affect the price?

Connecting a custom domain, removing builder ads, selling products, and avoiding transaction fees are the features most often gated to higher plans. Knowing which ones you need tells you the tier to budget for. Check the vendor for current pricing.
