Imagine you’ve built a gorgeous new website. It’s sleek, it’s modern, and your boss is already patting you on the back saying, “Have a massive bonus.” Well, maybe not that far, but still, you’re feeling smug.
Then someone tries to use it…
Maybe with a screen reader, or on a shaky mobile connection, or simply with less-than-perfect eyesight, and suddenly that shiny design is about as useful as a chocolate teapot. And not even the nice kind, that dark stuff nobody really likes…
That’s the blunt truth: accessibility isn’t a “nice extra”. It’s the difference between a website people can use and one they abandon in frustration. And if your site isn’t accessible, it’s not just your visitors who’ll notice. Search engines, regulators, and your brand reputation will, too.
So, why is accessibility important in web design?
Because it’s about more than ticking legal boxes, it’s about making your site usable for everyone, boosting your reach, and proving your brand actually cares about the people it’s trying to sell to.
At its simplest, accessibility in web design means making sure your site works for everyone.
Not just people with the latest laptop and perfect eyesight. We are talking about people using screen readers, people navigating with a keyboard instead of a mouse, or anyone who just wants to read your content without squinting at grey text on a slightly darker grey background.
So, what is accessibility in web design in practice? Think of it as clearing away digital trip hazards:
Accessibility helps more than people with disabilities. It helps anyone using your site in less-than-perfect conditions: someone on slow Wi-Fi, someone scrolling one-handed on a phone, someone whose eyesight is not what it used to be.

Here’s the thing, websites don’t exist in a vacuum. They exist in the real world, where laws, search engines, and actual humans all expect you to play fair. That’s why the question why accessibility is important in web design doesn’t just have one neat answer, it has three.
In the UK, the Equality Act 2010 makes it clear: if your website shuts people out, you could be breaking the law. Globally, the Web Content Accessibility Guidelines (WCAG) set the standard, and businesses everywhere are expected to keep up. Ignoring them isn’t just bad practice, it’s potentially a legal liability.
Accessibility isn’t charity work, it’s good business. Every time you remove a barrier, you expand your audience. That means more leads, more sales, and more chances for your marketing team to look like heroes.
Search engines love accessible sites too: alt text, semantic HTML, clear structure, all the stuff that makes a site easier for humans also makes it easier for Google to rank. In short, accessibility is a quiet SEO superpower.
At the heart of it all, accessible design makes people feel welcome. If your website is easy to use no matter someone’s ability, device, or environment, they’ll remember it, and they’ll come back. That loyalty is worth more than any flashy rebrand.
So, why is accessibility important in web design? Because it protects your business legally, strengthens your SEO, and, most importantly, it shows your customers you actually care about them.

If you’ve ever tried to use a website that looked like it was designed by someone squinting through a keyhole, you’ll know that accessibility mistakes aren’t rare, they’re everywhere.
The problem isn’t that businesses don’t care. It’s that marketing teams get so caught up in making things look “on brand” that they forget to check if anyone can actually use them.
Here are the usual culprits:
Looks slick. Totally useless. If your entire homepage is one giant image, congratulations — you’ve just created a poster, not a website. Screen readers can’t interpret it, search engines can’t crawl it, and visitors can’t interact with it. Unless your goal is to set a world record for fastest bounce rate, avoid this.
Grey text on a slightly darker grey background might look minimalist in the design mock-up, but in real life it’s a digital eye test. Accessibility standards (like WCAG’s 4.5:1 contrast ratio for normal text) exist for a reason. If your copy is forcing users to zoom in like they’re examining an ancient scroll, you’ve got a problem.
Ever tried filling in a form that refuses to let you tab between fields? Or one that errors out because you didn’t put a dash in the “phone number” box? Poorly built forms are accessibility nightmares. They frustrate users, tank conversion rates, and make your brand look amateur.
It’s also one of the fastest ways to sabotage your efforts to generate leads from your website.
Video is brilliant, unless you forget captions. Then it’s just a silent mime show for anyone who’s deaf, hard of hearing, or simply trying to watch in the office without announcing it to the entire floor. Adding captions and transcripts isn’t optional; it’s a bare minimum.
The truth is, these accessibility challenges aren’t hard to fix, they’re just easy to ignore. And when you ignore them, you don’t just frustrate users, you shut the door on potential customers.
Here’s the awkward truth, even if you memorise the WCAG guidelines and tape them to your monitor, building an accessible site from scratch can feel like assembling IKEA furniture without the instructions. Technically possible, but likely to end with swearing, and a wonky result with few missing screws.
That’s why the choice of CMS platform matters more than most marketers realise. Some content management systems make accessibility a daily battle. Others, like HubSpot CMS, make it part of the furniture.
Most websites don’t fail because people don’t care. They fail because every rushed update chips away at accessibility until it collapses. HubSpot stops that rot by baking compliance into the process, so you don’t need a developer on speed-dial every time you add a landing page.

Want the full breakdown? Our guide on Should You Use HubSpot CMS? explains why it’s one of the most accessible and scalable options out there.
If you’ve skimmed this far (no judgement, we all do it), here’s the short version: accessibility isn’t optional.
It’s the backbone of user experience, a legal requirement you can’t ignore, and the secret sauce for building trust in your brand. In other words, why is accessibility important in web design? Because without it, you’re shutting the door on customers, tanking your SEO, and practically begging regulators to come knocking.
And here’s the kicker: Getting accessibility right doesn’t have to feel like a second job. With the right platform, it’s not just achievable, it’s automatic. That’s where HubSpot CMS comes in: it’s the difference between wrestling with code at 11 pm and publishing an inclusive, compliant, SEO-friendly site before your coffee goes cold.
So the next time someone in your business asks what accessibility is in web design, you’ll know the answer…
It’s how you make sure every single visitor can actually use your site, and why that makes you look smarter, more professional, and frankly, a lot nicer than your competitors.
