CMS stands for Content Management System. Put simply, a CMS is an admin area where you change what is on your website, such as text, photos, products and articles, without touching any code.

For a company, the CMS decides whether the website becomes a working tool that is always up to date, or a digital brochure that is left to go stale. This article explains how a CMS works, what it does for you and what to look for when choosing one.

How does it work?

With a CMS, your team signs in to the admin area with an email address and password. There they can:

  • Add or edit products and their categories
  • Write and publish articles
  • Change the text and photos on a page
  • Set page titles and descriptions for Google
  • Manage images in a single media library

Once the changes are saved, the website is updated. There is no need to contact a developer and wait for a slot in their schedule.

Example: adding a new product

Say your company launches a new product. With a CMS, the process looks roughly like this:

  1. Sign in to the admin area.
  2. Open the products section and choose to add a product.
  3. Fill in the name, description, specifications and category.
  4. Upload the product photos to the media library.
  5. Save and publish. The product appears in the catalogue straight away.

Without a CMS, you would have to send all of that information to a developer, wait for them to do it, then check the result. For one product that may not feel like much, but across dozens of products a year the difference is huge.

Why does a company website need a CMS?

Content stays up to date

New products, company information and recent projects change often. Without a CMS, websites tend to be left out of date because every change is a hassle. An out-of-date website makes prospective customers wonder whether your company is still active.

It costs less in the long run

Without a CMS, every small change means a fee and a wait. With a CMS, your team does it themselves in minutes.

It supports SEO

Google favours websites that are active and relevant. With a CMS, you can regularly add articles and product pages and set the title and description of each page. All of this helps your website get found in search.

Several people can manage it

A good CMS has user settings and access rights. For example, the marketing team may write articles, while only an administrator may change the website settings. That way work can be shared without worrying about accidental changes.

Off-the-shelf CMS or a tailored CMS?

There are two common approaches. An off-the-shelf CMS offers lots of features for many kinds of website, but it often feels complicated for a team that only wants to update products and articles. It also needs regular updates to stay secure. If you use WordPress, follow this monthly security checklist.

A CMS tailored to your business is usually simpler: its menus and terms follow the way your company works, for example products, industries or materials. As a result, your team picks it up faster and updates content more often.

Which is better depends on your needs. What matters most is that your team actually uses it.

What to look for

  • Easy to use: a complicated CMS ends up unused. Ask for a demo before you decide.
  • Secure: the admin area must be well protected, with strong passwords and restricted access.
  • Still fast: the CMS must not make the website slow for visitors.
  • Fits your business: a product catalogue should use the terms your business uses.
  • Training included: make sure your team gets a short walkthrough of how to use it.

Tips for keeping your website updated

  1. Make one person responsible for the website's content.
  2. Set a simple routine, for example checking the products and writing one article each month.
  3. Prepare product photos of consistent quality.
  4. Review the main pages every few months, especially contact details and services.

Keeping CMS accounts secure

Your CMS accounts are the keys to your website. Use a strong, different password for each person, don't share one account across the whole team, and remove access for employees who have left your company. These simple steps prevent most security problems. Turn on two-step verification for admin accounts as well.

What doesn't need to be changed through the CMS?

A CMS is designed for content: text, images, products and articles. Major changes to the design or new features are usually still handled by a developer, because they affect the structure of the website. This split actually works in your favour: your team is free to change content without the risk of breaking the layout, while bigger changes are still handled by experienced people.

Frequently asked questions

Do I need technical skills to use a CMS?

No. If you are comfortable typing documents and uploading photos, you can use a CMS. A short training session is usually enough.

Do changes appear on the website straight away?

Generally, yes. Some CMSs take a moment to update the page, especially on websites optimised to be very fast. Ask your provider how long it takes.

What if I make a mistake while editing content?

A mistake in text or a photo can be fixed straight away by changing it back. For extra safety, make sure your provider makes regular backups.

A CMS turns your website from a static brochure into a working tool that your own team keeps up to date.
