One of our e-commerce clients couldn't figure out why their lead gen form had a 73% abandonment rate on mobile. The form looked fine on desktop. It worked in Chrome. But on mobile Safari with VoiceOver enabled? The submit button was completely invisible to screen readers. They'd been losing leads from an entire segment of users for months.

Form Accessibility Monitoring Is a Conversion Problem

Most teams think about accessibility as a compliance checkbox. Get the alt tags in place, add some ARIA labels, done. But form accessibility monitoring is really a conversion rate issue. If your forms don't work for people using assistive technology, keyboard navigation, or even just a slightly older browser, you're leaving money on the table.

About 15% of the global population has some form of disability. That's not a small segment. And many accessibility issues also affect people without disabilities: tab order problems frustrate power users, poor contrast makes forms hard to read in sunlight, and missing label associations confuse autofill.

The 7 Signs You Need to Watch For

Here's what we check during our form accessibility monitoring reviews:

1. Tab order doesn't follow visual layout. Press Tab through your form. If the focus jumps randomly between fields, keyboard users will bail.

2. Error messages aren't connected to their fields. When a user submits invalid data, does the error message announce which field has the problem? Or does a generic "please fix errors" appear at the top with no context?

3. Labels are missing or use placeholder text only. Placeholder text disappears when you start typing. If that's your only label, users forget what the field is asking for.

4. Color is the only error indicator. Red borders mean nothing to someone who's colorblind. You need text cues too.

5. The submit button isn't reachable by keyboard. This happens more often with custom-styled buttons than you'd expect.

6. Dynamic form sections don't announce changes. If selecting "Business" from a dropdown reveals three new fields, screen readers need to know those fields appeared.

7. CAPTCHA blocks assistive technology. Some CAPTCHA implementations are nearly impossible for screen reader users. Google's reCAPTCHA v3 handles this better, but older versions can be a wall.

How I Test Forms for Accessibility

I use a simple three-step process that takes about 20 minutes per form. First, I unplug my mouse and navigate the entire form with just the keyboard. Can I reach every field? Can I submit? Second, I turn on VoiceOver (Mac) or NVDA (Windows) and listen to what gets announced. Third, I run the form URL through PageSpeed Insights, which includes a basic accessibility score based on Lighthouse.

We also use Google Search Console to check for Core Web Vitals issues on form pages, since poor performance and poor accessibility often show up on the same pages.

Make It Part of Your Routine

Form accessibility monitoring shouldn't be a one-time project. Every time you update a form, change a field, or swap out a plugin, run those three checks. Better yet, set up automated monitoring that flags when form elements change or break.

FunnelLeaks can watch your form pages for structural changes and alert you when something shifts. It won't replace a full accessibility audit, but it catches the regressions that happen after launches. Your forms are the handshake between your marketing and your revenue. Make sure everyone can shake hands.
