How to Check Your Website Accessibility

Here’s the honest version: you can’t tell if your website accessibility just by looking. A site that looks clean and works fine with a mouse can still be unusable for someone relying on a screen reader, a keyboard, or high-contrast mode. Accessibility lives in the parts you don’t see. The good news is that checking it is something you can start today, and most of the first pass costs nothing.

What does website accessibility actually mean?

Website accessibility means people with disabilities can perceive, navigate, and use your site as effectively as anyone else. The benchmark is the Web Content Accessibility Guidelines (WCAG), and most legal obligations land at Level AA. “Fully accessible” isn’t a badge you earn once. It’s a standard your site either meets right now or it doesn’t, page by page, and counts on you to maintain it. it can quietly break every time you publish something new.

Can you check website accessibility for free?

Yes, you can check for free, and you should start there. Free automated scanners like WAVE, axe DevTools, and Google Lighthouse crawl a page in seconds and flag the obvious failures: missing alt text, low contrast, unlabeled form fields, and empty links. Run one on your busiest pages before doing anything else. That gives you a baseline and a to-do list in about the time it takes to read this paragraph.

What can automated checkers actually catch?

Automated tools are fast and worth running, but testing across the industry consistently puts their coverage at roughly 30 to 40 percent of real accessibility issues. They confirm an alt text exists; they can’t tell you it’s meaningful. They see a heading tag; they can’t tell you the order makes sense. The rest needs a person, which is the part most teams skip.

How do you test a website using only a keyboard?

Unplug your mouse and try to use your own site. Anything a mouse can do, a keyboard has to do too. Work through these:

1. Tab through the page. Every link, button, and field should be reachable, in an order that matches the layout.
2. Watch for a visible focus outline. If you can’t see where you are, neither can a keyboard user.
3. Open every menu, modal, and dropdown with Enter or Space, and close it with Escape.
4. Make sure you never get trapped, stuck inside a widget with no way back out.

If you can’t finish a purchase, a signup, or a search with the keyboard alone, a large group of your users can’t either.

How do you know if a screen reader can use your site?

The best way to know is to turn one on and listen. Every major device ships with one for free: VoiceOver on Mac and iPhone, Narrator on Windows, TalkBack on Android. Close your eyes and navigate. Do the headings describe the page? Do images announce something useful, or just “image”? Do form fields say what they’re for? If the spoken version is confusing or silent in the wrong places, the site is inaccessible, however polished it looks on screen to sighted users.

What are the most common accessibility issues to check for?

A handful of problems account for the majority of failures. Check these first:

1. Missing or meaningless alt text on images.
2. Low contrast between text and background. Aim for at least a 4.5:1 contrast ratio on body text.
3. Form fields with no labels, so a screen reader just announces “edit, blank.”
4. Links that read “click here” or “read more” with no context around them.
5. Headings used for visual blocks rather than real document structure.
6. Color as the only signal, like a red border on an error with no text or icon about what is being indicated.
7. Video without captions, and audio without a transcript.

Fix these seven and you’ve closed most of the doors your users actually hit.

When should you hire a website accessibility audit service?

When the free pass has taken you as far as it can and the stakes are real, it’s time to hire. A DIY check finds the obvious problems, but it won’t give you a defensible, WCAG-referenced record, and it won’t catch the subtle failures buried in dynamic or logged-in content. Professional website accessibility audit services pair automated scanning with manual expert testing on real assistive technology, then hand you a prioritized report your developers can act on.

That matters most when you’re facing a compliance deadline, a legal complaint, or a site too large to test by hand. It’s also where money leaks, because audit pricing varies wildly and not every quote is fair. Before you sign anything, this guide to what a website accessibility audit should actually cost is worth ten minutes. The right website accessibility services don’t just tell you what’s broken. They tell you what to fix first.

So, is your website fully accessible?

Probably not fully, and that’s normal. Almost no site is. “Fully accessible” is less a finish line than a habit: scan often, test with a keyboard and a screen reader, fix the common issues, and bring in an expert when the stakes justify it. Start with one page and the tools already on your machine. Nobody gets there in one pass. The teams that get there at all are the ones that keep checking.
