In a rush? Here's the summary

Most business websites have accessibility problems their owners don't know about. This guide explains what ADA and WCAG compliance mean in plain English, why it matters for your business, and how to find out where your site stands.

Does my website legally need to be ADA compliant?

No law explicitly names websites, but courts increasingly apply the ADA to businesses that serve customers or clients online. Companies of all sizes have faced demand letters and lawsuits over inaccessible sites.

What is WCAG and why does it matter?

WCAG stands for Web Content Accessibility Guidelines. It's the global standard defining what an accessible website looks like: covering contrast, navigation, and screen readers. Courts use it as their benchmark.

How do I know if my website is accessible?

Most issues aren't visible to sighted users. Free tools like Lighthouse and WAVE extension can surface common problems, but they only catch about half of the of issues without a manual review.

Web accessibility is easy to overlook. Most of its work is invisible to users who don't rely on assistive technologies. But there are real risks to ignoring it, and huge wins hiding behind it: much better SEO, AI chatbots can crawl it more effectively, and the obvious — a site that works for more of the people.

What does web accessibility actually mean?

An accessible website is one that works for everyone. This includes people who navigate by keyboard instead of a mouse, use screen readers to consume content, or need higher contrast to read text clearly.

The standard that defines all of this is called WCAG: the Web Content Accessibility Guidelines. It's maintained by the W3C, the same organization that governs the core standards of the web. WCAG 2.1 AA is the widely accepted benchmark, and it's what auditors, regulators, and courts point to when accessibility comes into question.

Most business owners have never heard of it. Most business websites don't fully meet it.

The risk: bot just a big-company problem

You shouldn't be surprised to know that accessibility lawsuits and demand letters aren't reserved for Fortune 500 companies. Small and mid-sized businesses get targeted too — often because they're easier targets, not harder ones.

The playbook is pretty routine. Automated tools scan websites for common WCAG violations. When they find them, a demand letter follows. Most businesses settle, fix the issues, and move on. Some don't find out until it's more complicated than that.

We're not lawyers and this isn't legal advice. But the pattern is real, it's not slowing down, and "we didn't know" isn't a reliable defense. The good news is that most accessibility issues are fixable, and fixing them comes with an unexpected upside.

The opportunity: accessible websites perform better

This is the part most people don't know about, and it's genuinely under-appreciated.

When you build an accessible website, you're doing a lot of the same things that make a site perform better in search. Proper heading structure helps screen readers — but also helps Google understand your page hierarchy. Descriptive alt text helps visually impaired users, but also feeds image search. Clean semantic HTML helps assistive technologies navigate your content, and helps search engine crawlers do the same. Are you noticing the pattern?

The connection to AI is even more direct. LLMs and AI answer engines parse websites the same way screen readers do: they rely on structure, labels, and semantic meaning. A well-structured, accessible page is easier to crawl, easier to understand, and more likely to get cited in an AI-generated answer. AEO and accessibility aren't separate workstreams, they're the same!

Then there's the audience math. Roughly 1 in 4 adults in the U.S. lives with some form of disability. An inaccessible site carries legal risk and quietly turns away a meaningful slice of the people trying to engage with your business.

What most websites get wrong

The most common issues are invisible to sighted users browsing normally: low color contrast, images missing alt text, forms that can't be navigated by keyboard, interactive elements that screen readers can't identify.

If you test for accessibility at all, you're already ahead. Free tools like Lighthouse (you might know it as Google PageSpeed) are a great starting point. But they only catch about half of real issues.

The rest requires a trained eye: checking focus order, semantic structure, interactive labeling, and how the page actually behaves under a screen reader. This is why most sites that "passed the test" still have problems.

How we audit for accessibility at Floresta

When we run an accessibility audit, we use automated tools as a first line of defense, then work through a 40+ point checklist built around the full WCAG 2.1 AA spec. Automated scanning first, manual review second.

Automated tools surface the obvious issues. Manual review catches the rest: the focus traps, the unlabeled buttons, the heading hierarchy that looks fine visually but reads like noise to a screen reader. We combine Lighthouse and the axe extension for scanning, then go hands-on from there.

We go through this checklist for every website launch. For websites we maintain post-launch, we audit regularly and document and fix every issue found. That way, business owners know what we find and fix, and other vendors know what's been done.

Curious how your site stacks up? We'll perform and accessibility audit for free and tell you the exact tools we use to test. Just get in touch.

So... does your website need to be ADA compliant?

There's no single law with a yes or no answer. But if your website is how people find, evaluate, or work with your business, the practical answer is yes.

The risk is real, but so is the upside. And most of the work that makes a site accessible makes it better in every other way too.

I think that's a pretty good reason to stop putting it off.
