10 WCAG Compliance Checks Every Website Should PassJune 16 ,2026
Introduction
Website accessibility is no longer optional. Today, businesses, organizations, and website owners are expected to create digital experiences that everyone can use, including people with disabilities. This is where WCAG comes in.
WCAG stands for Web Content Accessibility Guidelines, a set of internationally recognized standards designed to make websites accessible to all users. These guidelines help people with visual, hearing, motor, and cognitive impairments navigate and interact with websites effectively.
For beginners, WCAG may sound technical, but many accessibility improvements are simple to implement. In this blog, we will explore 10 essential WCAG compliance checks that every website should pass to improve accessibility, user experience, and overall website performance.
What Is WCAG?
WCAG is a framework developed by the World Wide Web Consortium (W3C). It provides recommendations for making web content accessible to people with disabilities.
The guidelines are built around four key principles:
-
Perceivable – Information should be easy to see and hear.
-
Operable – Users should be able to navigate the website easily.
-
Understandable – Content and functionality should be clear.
-
Robust – Content should work across different devices and assistive technologies.
1. Ensure Proper Color Contrast
One of the most common accessibility issues is poor color contrast between text and background.
For example, light gray text on a white background can be difficult for users with visual impairments to read.
Best Practices
-
Use dark text on light backgrounds or vice versa.
-
Maintain sufficient contrast ratios.
-
Test colors using accessibility tools.
Good contrast improves readability for all users, not just those with disabilities.
2. Add Alternative Text to Images
Alt text (alternative text) describes images for users who rely on screen readers.
When an image cannot be viewed, the screen reader reads the alt text aloud, helping users understand the image's purpose.
Best Practices
-
Describe the image clearly.
-
Keep descriptions concise.
-
Use empty alt attributes for decorative images.
Example:
Instead of:
"image1.jpg"
Use:
"A woman shopping online using a laptop."
3. Make Your Website Keyboard Accessible
Some users cannot use a mouse and depend entirely on keyboards for navigation.
Every important function on your website should be accessible using keyboard controls.
Check These Elements
-
Navigation menus
-
Forms
-
Buttons
-
Popups
-
Dropdown menus
Users should be able to move through content using the Tab key without getting stuck.
4. Use Clear Heading Structure
Headings help users understand content organization and navigate pages efficiently.
Screen readers often use headings to jump between sections.
Best Practices
-
Use one H1 heading per page.
-
Follow a logical hierarchy (H1 → H2 → H3).
-
Avoid skipping heading levels.
A well-structured page improves both accessibility and SEO.
5. Provide Labels for Forms
Forms are critical for lead generation, registrations, and customer inquiries.
Without proper labels, screen readers may not identify what information users need to enter.
Example
Instead of:
-
Empty text box
Use:
-
Name
-
Email Address
-
Phone Number
Clearly labeled forms improve usability and reduce errors.
6. Include Captions for Videos
Many users have hearing impairments and cannot access audio content without captions.
Captions display spoken words and important sounds in text format.
Benefits
-
Improves accessibility
-
Enhances user engagement
-
Helps users in noisy environments
-
Supports multilingual audiences
Every video containing speech should include accurate captions.
7. Ensure Links Are Descriptive
Generic links such as "Click Here" or "Read More" provide little context for screen reader users.
Instead, use descriptive link text.
Examples
Poor:
-
Click Here
Better:
-
Download the Digital Marketing Guide
-
Learn More About Website Accessibility
Descriptive links improve navigation and understanding.
8. Allow Users to Resize Text
Some users need larger text to read content comfortably.
Your website should allow users to zoom or resize text without breaking the layout.
Best Practices
-
Use responsive design techniques.
-
Avoid fixed font sizes.
-
Test zoom functionality at 200%.
Content should remain readable regardless of screen size or zoom level.
9. Avoid Auto-Playing Content
Auto-playing videos, audio, and animations can create accessibility challenges.
They may distract users, interfere with screen readers, or cause difficulties for people with cognitive disabilities.
Recommendations
-
Avoid automatic playback.
-
Provide pause and stop controls.
-
Let users choose when content starts.
Giving users control creates a more accessible experience.
10. Test with Screen Readers
Screen readers help visually impaired users interact with websites.
Testing your website using screen readers can reveal accessibility issues that automated tools may miss.
Things to Check
-
Navigation flow
-
Form accessibility
-
Heading structure
-
Image descriptions
-
Link clarity
Regular testing ensures your website remains accessible as new content is added.

Conclusion
WCAG compliance is essential for creating websites that are accessible, user-friendly, and inclusive. By focusing on proper color contrast, image alt text, keyboard navigation, heading structure, form labels, video captions, descriptive links, text resizing, controlled media playback, and screen reader testing, website owners can significantly improve accessibility for all users.
Accessibility should be considered from the beginning of the web design process rather than as an afterthought.
