ARIA Labels: When to Use Them and When to Avoid Them

Introduction

If you're building websites or working with digital products, accessibility has likely emerged as a key priority. From meeting web accessibility standards to ensuring inclusivity for users with disabilities, developing accessible interfaces is no longer optional—it's a standard business expectation.

One of the most misunderstood yet vital components of accessible web development is ARIA (Accessible Rich Internet Applications). Specifically, ARIA labels like aria-label, aria-labelledby, and aria-describedby are frequently used—sometimes correctly, sometimes not. While these attributes can significantly enhance the experience for screen reader users, misuse or overuse of ARIA can do more harm than good.

In this article, we’ll explore ARIA labels in depth: what they are, why they matter, situations where you should use them, and crucially, when it’s best to avoid them. We’ll also highlight how platforms like allyWay, a powerful accessibility support solution, can help bridge these gaps, assisting your business in improving accessibility while saving time and effort.

Let’s clarify how ARIA labels fit into the bigger picture of accessibility—and how to use them wisely.

Understanding ARIA: A Foundation

The ARIA specification (Accessible Rich Internet Applications) is a set of HTML attributes developed by the W3C to improve accessibility in dynamic web content.

While HTML5 already has many semantic elements (<button>, <nav>, <header>, etc.), ARIA fills the gap for custom widgets and complex UI components that aren't inherently accessible.

What Are ARIA Labels?

ARIA labels are attributes that convey additional information to assistive technologies like screen readers. There are three primary ARIA label attributes:

Attribute	Purpose
`aria-label`	Defines a string label for the element
`aria-labelledby`	References another element’s text as a label
`aria-describedby`	References another element to provide descriptive text or instructions

Each one serves a unique purpose and fits specific situations.

Why ARIA Labels Matter

When implemented correctly, ARIA labels improve:

✓ Screen reader comprehension
✓ Navigation for users with vision impairments
✓ Overall inclusivity of interactive UI components

In many cases, screen readers rely on these labels to announce context, purpose, or instruction that users might otherwise miss—especially with non-standard, customized widgets or visually styled components like SVG buttons or icon-only links.

Accessibility isn’t just about meeting guidelines like WCAG 2.1 or conforming with policies such as the ADA, EN 301 549, or the European Accessibility Act. It’s about creating digital spaces where everyone, regardless of ability, can participate seamlessly.

With tools like allyWay supporting accessibility optimization, web teams can more confidently build toward this goal.

When to Use ARIA Labels

Here’s where ARIA labels become not just helpful—but essential.

1. Icon-Only Buttons

Imagine a close button represented by an "X" icon without any text. Screen readers won’t understand its purpose unless explicitly told.

Correct usage:

<button aria-label="Close">✖</button>

Why: aria-label gives a textual name to a visual element.

2. Custom Interactive Widgets

For elements like sliders or tabs built with divs or spans, appropriate ARIA roles and labels make them operable and understandable.

Example:

<div role="tab" aria-label="Shipping Information"></div>

Why: When semantic HTML is not available, ARIA bridges the gap.

3. Form Fields Without Visible Labels

If a form input has no visible <label>, users may have no idea what the field is for unless an ARIA label is present.

Correct usage:

<input type="text" aria-label="Phone number">

Why: Ensures clarity for screen readers when visual labels are missing.

4. Grouping Information

Use aria-labelledby to associate descriptive content when multiple elements need context.

Example:

<div id="sectionTitle">Contact Info</div>
<form aria-labelledby="sectionTitle">
...
</form>

Why: Allows screen readers to announce contextual grouping.

5. Adding Help Text

aria-describedby is perfect for referencing tooltips, helper content, or form field instructions.

Example:

<input type="email" aria-describedby="emailHelp">
<small id="emailHelp">We’ll never share your email.</small>

Why: Adds extended guidance beyond the main label.

allyWay Tip: These ARIA enhancements can be verified and optimized using allyWay’s accessibility auditing tools, which help identify missing or misused ARIA attributes across your website.

When Not to Use ARIA Labels

ARIA is powerful, but it’s not a fix-all solution. Overuse or incorrect use can lead to accessibility regressions.

Here are top scenarios to avoid:

1. Replacing Native HTML with ARIA

Don’t use ARIA when native HTML already solves the problem. For instance, <button> is better than <div role="button">.

Bad Example:

<div role="button" aria-label="Submit"></div>

Better:

<button>Submit</button>

Why: Most browsers and assistive tech handle semantic HTML better by default.

2. Duplicating Visible Labels

Don’t use aria-label in addition to a visible label—it creates redundant speech output.

Inefficient:

<label for="username">Username</label>
<input id="username" type="text" aria-label="Username">

Correct:

<label for="username">Username</label>
<input id="username" type="text">

Why: Screen readers will announce both labels.

3. Invisible Content Already Announced

Avoid aria-label on content that is already obvious, like headings or links with descriptive text.

Redundant:

<a href="/contact" aria-label="Contact Us">Contact Us</a>

Cleaner:

<a href="/contact">Contact Us</a>

4. Placeholder as Label

You shouldn’t rely on placeholders as a replacement for labels, ARIA or not. Placeholders disappear on input and aren’t accessible.

Incorrect:

<input type="text" placeholder="Email" aria-label="Email">

Preferred:

<label for="email">Email</label>
<input id="email" type="text">

Why: Labels remain accessible at all times, helping all users.

FAQ: ARIA Labels and Accessibility

Q1: Is aria-label read by all screen readers?
Yes, most modern screen readers support aria-label, although behavior may vary slightly between platforms. Always test across devices.

Q2: Can allyWay fix incorrect ARIA labels automatically?
allyWay can identify accessibility issues, including ARIA misuse. It can guide improvements through its suggestions, but manual review is recommended for critical elements.
