Website Terms Explained: A Plain-English Glossary for Business Owners
A plain-English glossary of website terms for business owners, from DNS and CMS to GA4, Core Web Vitals and AEO, so you can make better calls about your site.
This glossary explains the website terms business owners hear most, in plain English. It covers the basics like domain, hosting, DNS and CMS, design terms like CTA and responsive design, SEO terms like backlinks, schema and Core Web Vitals, analytics terms like GA4 and bounce rate, and maintenance terms like 301 redirects and backups.
You're in a meeting about your new website and someone says "we'll sort the DNS, set up the CMS Collections and check your Core Web Vitals", and you nod like you know what any of that means. I've watched a lot of smart, successful business owners do that nod.
You don't need to become technical. But knowing the basic words means you can ask better questions, spot when someone's fobbing you off, and make decisions about your site with confidence. Here are the website terms that come up most, in plain English.
What are the basic website terms every business owner should know?
Domain
Your website's address, like yourbusiness.com.au. You rent it yearly from a registrar. Make sure it's registered in your name or your business's name, not your web person's. (If you've wondered about the www bit, here's www vs non-www explained.)
Hosting
Where your website's files live so people can load it. If the domain is your street address, hosting is the land your house sits on. Webflow and Squarespace include hosting; WordPress usually needs separate hosting.
DNS
The settings that point your domain to your hosting and your email. When a site "goes live", it's often a DNS change. Get it wrong and your email can stop working, so it's worth having someone who knows what they're doing.
SSL / TLS and HTTPS
The security certificate that encrypts information between your site and your visitors, and gives you the padlock and "https" in the address bar. It's technically called TLS now, but most people still say SSL. Every site needs one.
Browser
The app people use to view websites: Chrome, Safari, Firefox or Edge. Google is a search engine, not a browser (a common mix-up).
CMS (Content Management System)
The system you log in to so you can edit your website without touching code. Webflow, WordPress and Squarespace all have one.
CMS Collections
In Webflow, Collections are structured sets of content like blog posts, case studies or team members. You fill in a template once, and every new item looks consistent.
Front end and back end
The front end is everything visitors see and click. The back end is the behind-the-scenes part: the database, server and settings that make it all work.
What do the design and user experience terms mean?
Homepage and landing page
Your homepage is the main page of your site and does a lot of jobs at once (here's what a homepage should include). A landing page is built for one specific purpose, like a campaign or offer, with one clear action.
CTA (Call to Action)
The thing you want someone to do next, usually a button: "Book a call", "Get the guide". Every key page needs one obvious CTA.
Responsive design
A site that adjusts to fit phones, tablets and desktops. For most service businesses, more than half of visitors are on mobile, so check your site on your phone first.
Accessibility
Making your site usable for people with disabilities: readable colour contrast, captions on videos, clear headings and text that works with screen readers. It's good practice and good for everyone.
Alt text
A short written description of an image, read out by screen readers and used by search engines to understand the picture. Here's how to optimise your website images, alt text included.
Favicon
The tiny icon in the browser tab, usually a simplified version of your logo.

What do the SEO and search terms mean?
SEO (Search Engine Optimisation)
Making your site easier for search engines to understand and trust, so it shows up when the right people search. It covers your content, your site structure, the technical setup and your reputation elsewhere online.
SERP
Search Engine Results Page: the page you see after you search on Google.
Backlinks
Links from other websites to yours. Links from relevant, credible sites act like votes of confidence. More on what backlinks are and why they matter.
Sitemap and indexing
A sitemap is a list of your pages you give to search engines. Indexing is when Google adds a page to its search results. If a page isn't indexed, nobody can find it in Google. The "Pages" report in Google Search Console shows which pages are indexed and why others aren't.
Schema (structured data)
Extra code that labels your content for search engines and AI tools: "this is a business, here's the address, these are FAQs". It helps them understand you more precisely.
E-E-A-T
Experience, Expertise, Authoritativeness and Trustworthiness. It's how Google describes the qualities it looks for in helpful content. For service businesses, it's a good reminder to show real proof: case studies, credentials and your own experience.
AEO and AI Overviews
AI Overviews are the AI-written answers Google shows at the top of some searches. AEO (Answer Engine Optimisation) is making your content clear enough that tools like Google, ChatGPT and Perplexity can use it in their answers. Here's what AEO is and whether you should care.
Core Web Vitals
Google's measures of how a page feels to use: how fast the main content loads (LCP), how quickly the page responds when you tap or click (INP), and how much the layout jumps around while loading (CLS).
What do the analytics terms mean?
GA4 (Google Analytics 4)
The current version of Google Analytics. The older version stopped collecting data in 2023 (Universal Analytics was retired then), so if your reports stopped then, that's why. Here's how to set up Google Analytics properly.
Sessions and engagement rate
A session is one visit to your site. Engagement rate is the percentage of sessions where someone stayed at least 10 seconds, viewed more than one page, or completed a key event.
Bounce rate
In GA4, bounce rate is simply the opposite of engagement rate: the percentage of sessions that weren't engaged. A high bounce rate on its own isn't a disaster, but a high one on your key pages is worth a look.
Key events and conversion rate
Key events are the actions you've told GA4 matter most, like an enquiry form submission or a booking. Your conversion rate is how often visits turn into those actions.
What do the technical and maintenance terms mean?
404 error
"Page not found". The page has moved or been deleted, or the link has a typo. A few are normal; lots of them mean broken links to fix.
403 error
"Forbidden". The server won't let the visitor see the page. This is usually a settings or permissions issue on the site itself.
301 redirect
A permanent forward from an old URL to a new one. Essential when you rebuild a site or change page addresses, so you don't lose the search rankings and links your old pages had built up.
Cache
Stored copies of your site's files so pages load faster. If you've made a change and can't see it, clearing your browser cache is usually the fix.
Plugins and integrations
Add-ons that give your site extra features, like booking tools, forms or chat. Handy, but every extra one is something to maintain and a potential cause of slow loading.
Backups
Saved copies of your site you can restore if something breaks. Ask your web person where yours are and how often they're taken.

Why does any of this matter for your business?
Because the words aren't the point, the decisions are. Knowing what a 301 redirect is means you'll ask about it before a rebuild. Knowing what key events are means you'll know whether your site is actually producing enquiries or just traffic.
If you'd rather not be across all of it, that's fair too. A Site Success Plan looks after the technical care, SEO and AEO for Webflow sites month to month. And if the bigger issue is that your site no longer reflects how good you are, True Bearings is my four-week brand strategy and website engagement, done for you.
What is the difference between a domain and hosting?
Your domain is your website address, like yourbusiness.com.au, which you rent yearly from a registrar. Hosting is where your website files live so people can load the site. If the domain is your street address, hosting is the land your house sits on. Platforms like Webflow and Squarespace include hosting, while WordPress usually needs it arranged separately.
What is bounce rate in Google Analytics 4?
In GA4, bounce rate is the percentage of sessions that were not engaged. It is the opposite of engagement rate. An engaged session is one where the visitor stayed at least 10 seconds, viewed more than one page, or completed a key event such as submitting an enquiry form. A high bounce rate on key pages is worth investigating.
Why should business owners learn common website terms?
Knowing the basic terms helps you ask better questions, understand what your web person is proposing and spot problems early. For example, knowing what a 301 redirect is means you will ask about it before a rebuild, so you do not lose search rankings. You do not need to be technical, just confident enough to make good decisions.
