If you’re new to WordPress, it can sometimes feel like everyone around it is speaking another language.

Themes. Plugins. Widgets. Hosting. Permalinks. SSL. Gutenberg.

And just when you think you’ve got the hang of it, someone throws another WordPress term at you.

The good news? You don’t need to become a WordPress expert to have a great website. You just need to understand the basics well enough to know what people are talking about and what your website actually needs.

So, let’s take some of the mystery out of WordPress.

Here’s your beginner-friendly glossary of the most common WordPress terms you’re likely to come across.

WordPress

WordPress is a content management system (CMS) that allows you to create and manage a website without needing to build everything from scratch with code.

It can be used for blogs, business websites, online stores, portfolios, membership sites, and more.

Think of WordPress as the foundation your website is built on.

There are two versions you may hear about:

• WordPress.org – the self-hosted version of WordPress, where you purchase your own hosting plan and have more control over your website.
• WordPress.com – a hosted service that offers different plans and takes care of much of the technical side for you.

When people talk about installing WordPress on their own hosting account, they’re generally talking about WordPress.org.

Domain Name

Your domain name is your website’s address on the net.

For example:

yourbusiness.ca

It’s what someone types into their browser to find your website.

Your domain is separate from your website hosting, although many companies offer both together.

Think of your domain as your street address and your website as the house sitting at that address.

Web Hosting

Web hosting is where the files that make up your website are stored.

When someone visits your website, their browser connects to your hosting server and retrieves the info needed to display your pages.

In our house analogy:

• Your domain is your address.
• Your hosting is the land your house sits on.
• Your website is the house.

Your hosting company can also affect things like website speed, security, backups, and reliability.

Dashboard

The WordPress Dashboard is the administrative area where you manage your website.

It’s the part of WordPress that visitors don’t see.

From your Dashboard, you can create posts and pages, install plugins, customize your site, manage comments, update WordPress, and more.

Think of it as the behind-the-scenes control room for your website.

Theme

A WordPress theme controls much of the visual appearance and layout of your website.

Your theme can determine things such as:

• Fonts
• Colours
• Page layouts
• Header and footer styles
• Navigation
• Blog layouts
• Buttons
• Overall design

A theme gives you a starting point for your website, but you can often customize it to better suit your brand.

And remember: a theme isn’t your brand.

You can change themes later, although doing so may require additional work to make sure everything still looks and functions properly.

Plugin

A plugin adds functionality to your WordPress website.

Need a contact form? There’s a plugin for that.

Want to improve SEO? There’s a plugin for that too.

Need an online store? Plugins can help with that as well.

Plugins can add features such as:

• Contact forms
• SEO tools
• E-commerce
• Website backups
• Security
• Analytics
• Social sharing
• Email marketing integrations

But there’s an important little word to remember:

Too many plugins can create problems.

You don’t need a plugin for every tiny feature. Choose reputable plugins that you actually need and keep them updated.

Page

A page is generally used for the more permanent, foundational content on your website.

Common website pages include:

• Home
• About
• Services
• Contact
• FAQ
• Privacy Policy

Pages usually aren’t organized by date in the way blog posts are.

Post

A post is typically used for regularly published content, such as blog articles or news updates.

For example:

Pages:
About, Services, Contact

Posts:

Simple Ideas for a Cozy Weekend

Posts can be organized using categories and tags.

Gutenberg / Block Editor

The WordPress Block Editor, called Gutenberg, is the editor built into modern WordPress.

Instead of creating one large block of content, you build your page or post using individual blocks.

There are blocks for things like:

• Paragraphs
• Headings
• Images
• Buttons
• Lists
• Columns
• Videos
• Quotes

The block approach makes it possible to create more flexible layouts without needing to write code.

Block

A block is an individual piece of content or layout within the WordPress Block Editor.

For example, a page might contain:

Heading block → Paragraph block → Image block → Button block

You can rearrange blocks, customize them, and combine them to create your page.

Once you understand blocks, the WordPress editor becomes much less intimidating.

Page Builder

A page builder is a tool that gives you additional ways to design WordPress pages.

Some page builders provide visual, drag-and-drop interfaces that allow you to create layouts without working directly with code.

Depending on your theme and setup, you may encounter page builders such as Kadence, Elementor, or Divi. I work with Kadence and this site is built upon it.

Not every WordPress website needs a page builder. The WordPress Block Editor has become increasingly capable on its own.

Widget

A widget is a small piece of content or functionality that can be placed in specific areas of your website.

Depending on your theme, widget areas might include:

• Sidebar
• Footer
• Header
• Other designated areas

Examples might include a search box, recent posts, categories, or a newsletter signup.

Some newer WordPress themes use blocks rather than traditional widgets, so you may see the terminology used differently depending on your setup.

Header

The header is the area at the top of your website.

It commonly contains:

• Your logo or site title
• Navigation menu
• Search
• Social media links
• A button or call to action

Your header is often one of the first things visitors see, so it’s an important part of your site’s navigation and branding.

Footer

The footer is the area at the bottom of your website.

It might include:

• Copyright information
• Navigation links
• Social media links
• Contact information
• Newsletter signup
• Privacy Policy
• Terms and conditions

A thoughtfully laid out footer gives visitors an easy way to navigate your website.

Navigation Menu

Your navigation menu helps visitors move around your website.

A typical business website might have:

Home | About | Services | Blog | Contact

Your menu should make it easy for visitors to understand what your website offers and find what they’re looking for.

You don’t need to put every page on your main menu. Keep your primary navigation focused on the most important areas of your website.

Permalink

A permalink is the permanent web address of a particular page or post.

For example:

yourwebsite.ca/wordpress-glossary

That’s the permalink for a specific article.

It’s generally a good idea to keep URLs short, descriptive, and easy for people to understand.

Slug

A slug is the part of a URL that identifies a specific page or post.

For example:

yourwebsite.ca/wordpress-glossary

The slug is:

wordpress-glossary

You can usually edit the slug when creating or editing a WordPress page or post.

Category

A category helps organize your blog posts into broader topics.

For example, a website about homemaking might have categories such as:

• Organizing
• Homemaking
• Recipes
• Home Decor

Categories help both visitors and search engines understand how your content is organized.

Tag

A tag is another way of organizing content, but tags are generally more specific than categories.

For example, a post in the Organizing category might have tags such as:

• Small Spaces
• Decluttering
• Cleaning
• Storage

You don’t need to add dozens of tags to every post. Choose two or three to help organize related content.

Media Library

The Media Library is where WordPress stores the images, PDFs, videos, and other media files you upload to your site.

From the Media Library, you can view and manage your uploaded files.

It’s worth keeping your media organized because a large website can accumulate a surprisingly large collection of images over time.

Featured Image

A featured image is the primary image associated with a page or blog post.

Depending on your theme, it may appear:

• At the top of a blog post
• On your blog page
• In related posts
• When your content is shared on social media

Think of it as the cover image for your post.

Alt Text

Alt text, or alternative text, describes an image.

It can help people using screen readers understand the purpose or content of an image.

Alt text can also help search engines understand images.

The key is to describe the image accurately and naturally rather than stuffing it with keywords.

For example:

Not ideal:
“WordPress website design small business website WordPress designer”

Better:
“Desk with laptop displaying a WordPress website”

SEO

SEO stands for Search Engine Optimization.

It’s the process of improving your site so that search engines can better understand your content and people can find it through search.

SEO can involve things like:

• Helpful content
• Relevant keywords
• Page titles
• Headings
• Internal links
• Site speed
• Mobile usability
• Descriptive URLs
• Image optimization

SEO isn’t a magic button you switch on. It’s an ongoing part of creating and maintaining a useful website.

Meta Title

A meta title, sometimes called an SEO title, is the title that search engines may display for a page in search results.

It helps communicate what the page is about.

A good title should be clear, descriptive, and relevant to the actual content on the page.

Meta Description

A meta description is a short description of a webpage that may appear underneath its title in search results.

It doesn’t guarantee higher rankings, but a clear and helpful description can help someone decide whether your page is what they’re searching for.

SSL Certificate

An SSL certificate helps establish a secure connection between your website and its visitors.

When a website has SSL, you’ll generally see HTTPS at the beginning of its address rather than HTTP.

You’ll also typically see a padlock symbol in your browser.

SSL is important for website security and visitor trust, particularly if your website collects information through forms, logins, or purchases.

HTTPS

HTTPS stands for Hypertext Transfer Protocol Secure.

In simple terms, it means information transferred between your visitor’s browser and your website is sent over a secure connection.

You’ll usually see it as:

https://yourwebsite.ca

rather than:

http://yourwebsite.ca

Backup

A backup is a copy of your website that can be restored if something goes wrong.

And trust me, things can go wrong.

A plugin update can cause a conflict with your theme. A website with a guessable password can be hacked. Something can accidentally be deleted.

That’s why backups are one of those behind-the-scenes tasks that aren’t particularly exciting, but are incredibly important. Your hosting company should offer you site and database (where your content lives) backups as one of the services included in your hosting plan.

A good backup system can save you a lot of stress when something unexpected happens.

Cache / Caching

Caching is a way of storing website files temporarily so they can be delivered faster when someone visits your site.

Caching can help improve website performance and loading times.

You may encounter caching through your hosting provider, a WordPress plugin, or another website optimization service.

If you’ve ever been told to “clear your cache,” this is what they’re talking about.

Responsive Design

A responsive website automatically adjusts its layout to work across different screen sizes.

That includes:

• Desktop computers
• Laptops
• Tablets
• Mobile phones

A website that looks beautiful on your laptop but is difficult to use on your phone isn’t doing its job very well.

Always check your website on different screen sizes before launching.

CSS

CSS stands for Cascading Style Sheets.

It’s a coding language used to control the appearance of a website.

CSS can control things such as:

• Colours
• Fonts
• Spacing
• Borders
• Layout
• Animations

You don’t need to know CSS to use WordPress, but you may hear the term if you’re working with a designer or troubleshooting a design issue.

HTML

HTML stands for HyperText Markup Language.

HTML provides the structure of webpages.

You don’t need to be an HTML expert to manage a WordPress website, but knowing that HTML is essentially part of the underlying structure of your pages makes some technical conversations easier to understand.

PHP

PHP is the programming language WordPress is primarily built with.

You generally won’t need to work directly with PHP as a beginner.

However, you may see the term when dealing with WordPress hosting, themes, plugins, or tech troubleshooting.

If someone tells you that you need to update your PHP version, they’re talking about the version of the programming language your site is running on.

Database

Your WordPress website uses a database to store information.

This includes things such as:

• Posts
• Pages
• Settings
• User info
• Comments

You usually don’t need to interact with your database directly.

It’s one of those behind-the-scenes things that quietly keeps your website running.

User Role

WordPress allows different users to have different levels of access.

Common user roles include:

• Administrator – has extensive control over the website – this is the top role.
• Editor – can generally create and manage content.
• Author – can generally create and manage their own posts.
• Contributor – can create posts but has more limited publishing permissions.

If you’re working with a VA, designer, writer, or other team member, user roles can help you give them the access they actually need without handing over complete control of your website.

Update

WordPress websites have several things that may need regular updates, including:

• WordPress itself
• Themes
• Plugins
• PHP

Updates can include security fixes, bug fixes, improvements, and new features.

Keeping everything updated is an important part of website maintenance, but it’s wise to have current backups before making major updates.

Maintenance

WordPress maintenance refers to the ongoing work required to keep your site healthy and functional.

This can include:

• Running updates
• Checking backups
• Monitoring security
• Checking links
• Removing unnecessary plugins
• Reviewing website performance
• Checking forms
• Testing important features

Your website isn’t really a “set it and forget it” project.

A little regular maintenance can prevent much bigger headaches later.

404 Error

A 404 error usually means the page someone is trying to visit can’t be found.

This can happen if:

• A page was deleted
• A URL was changed
• A link is incorrect
• Someone typed the address incorrectly

If you change the URL of an important page, you may need to set up a redirect so visitors and search engines can find the new location.

Redirect

A redirect automatically sends visitors from one URL to another.

For example, if you change:

yourwebsite.ca/old-page

to:

yourwebsite.ca/new-page

a redirect can send anyone visiting the old URL to the new one.

Redirects are especially useful when changing URLs or restructuring a website.

Favicon

A favicon is the small icon associated with your website that appears in places such as browser tabs and bookmarks.

It might be your logo, initials, or another simple brand mark.

It’s a tiny detail, but it helps your website feel polished and recognizable.

Call to Action (CTA)

A call to action, or CTA, tells your visitor what you’d like them to do next.

Examples include:

• Book a Consultation
• Shop Now
• Read the Blog
• Join the Email List
• Contact Me
• Download the Guide

A good website shouldn’t leave visitors guessing at what they’re supposed to do next.

Content Management System (CMS)

A content management system, or CMS, is software that allows you to create, organize, edit, and manage website content.

WordPress is a CMS.

The benefit of a CMS is that you don’t need to manually code every webpage whenever you want to make a change.

You Don’t Need to Know It All

If you’ve made it this far, congratulations – you now know a whole lot more WordPress terminology than you probably did when you started.

But here’s something important to remember:

You don’t have to know how every piece of your website works behind the scenes.

You don’t need to know PHP to write a blog post.

You don’t need to understand databases to add a new page.

And you certainly don’t need to become a web developer just to run a small business website.

Understanding the basics gives you confidence.

It helps you know what your web designer or developer is talking about. It makes troubleshooting a little less scary. And it helps you make better decisions about your site as your business grows.

Think of this glossary as something you can bookmark and come back to whenever you encounter a WordPress term that makes you pause.

There are no silly questions when it comes to your website.
