Accessibility Isn't a Compliance Checkbox. It's a Conversion Lever.
Accessibility usually enters a business through the legal team, framed as risk to be managed rather than an opportunity to be pursued. That framing isn't wrong, exactly, but it's incomplete. A lot of what the Web Content Accessibility Guidelines (WCAG) actually ask for overlaps directly with what makes a page convert better for everyone, not just users relying on assistive technology.
Where the overlap actually is
Strip away the legal language and a lot of WCAG comes down to things CRO practitioners already recommend for unrelated reasons:
- Sufficient color contrast. Also just makes CTAs and body copy easier to read for someone glancing at their phone in bright sunlight.
- Clear focus states on interactive elements. Also makes it obvious what's clickable, which reduces hesitation for every visitor, not just keyboard users.
- Descriptive link and button text instead of "click here." Also improves scannability for someone skimming a page rather than reading it top to bottom.
- Forms with properly associated labels and clear error messages. Also the exact thing that reduces abandonment on any form, for any user.
None of these are accessibility-specific best practices that happen to also help conversion. They're the same practice, described from two different angles.
The part that's easy to miss
A meaningful share of the population interacts with the web through some form of assistive technology or accommodation, whether that's a screen reader, increased text size, reduced motion settings, or simply low vision that makes low-contrast text hard to read. If your site works poorly for that segment, you're not avoiding a niche edge case. You're leaving conversions on the table from people who wanted to buy and couldn't complete the journey.
Where to start if you haven't touched this yet
You don't need a full WCAG AA audit to get meaningful value. Start with the things that are cheap to check and commonly broken: run your key pages through an automated contrast checker, tab through your own checkout using only the keyboard (no mouse) and see where you get stuck, and read your form's error messages out loud, if they don't tell someone exactly what to fix, they're costing you completions regardless of who's reading them.
This is one of those rare areas where doing the responsible thing and doing the commercially smart thing point in exactly the same direction. If you want it built into how we review your site, it's part of the standard process in a free consultation.
