What is CMS?

Content Management System

A CMS, or content management system, is software that lets you create, edit and publish website content through an easy dashboard, without writing code for every change.

How it works

The CMS stores your pages, images and settings, and a theme or design controls how they look. When you edit a page in the dashboard, the CMS updates the live site, so non-technical staff can make changes safely.

Common options

WordPress runs a large share of the web and is flexible with many plugins. Webflow suits design-led marketing sites. Shopify is built for online stores. Squarespace and Wix are simple all-in-one builders. Some larger sites use a headless CMS that feeds content to a custom front end.

How to choose

Think about who will edit the site, what it needs to do, like booking, selling or publishing, how much you want to customize and who will handle security updates. The best choice is the one your team will actually use and keep up to date.

Why CMS matters

Your CMS decides how easily you can update your site, how fast it loads and how well it supports SEO. The wrong choice can leave you stuck waiting on a developer for every small change, or rebuilding the site sooner than you'd like.

Ending the wait for small edits

A medical practice's old site needed a developer for every hours or staff change, so updates took weeks. Moving to a CMS with simple editing let the office manager update hours, add providers and post notices the same day.

Common mistakes

  • Picking by popularity alone

    The most popular CMS isn't always the best fit. Match the platform to your needs and your team's skills.

  • Too many plugins

    Piling on add-ons slows the site and creates security risks. Use only what you need and keep everything updated.

  • No one owns updates

    An outdated CMS is a common way sites get hacked. Decide who handles updates and backups from day one.
