Ensuring your SaaS website is accessible isn’t just about compliance—it’s about business growth, user satisfaction, and SEO performance. With more than 1 billion people worldwide living with some form of disability, creating an accessible website is critical for reaching a wider audience.

For SaaS products, accessibility ensures that every user can interact with your platform seamlessly, whether they’re navigating dashboards, filling forms, or completing transactions. In this guide, we’ll cover best practices for SaaS accessibility, provide actionable checklists, and show how Scanluma can simplify the process.

Why Accessibility Matters for SaaS Websites

Legal Compliance Across Regions

SaaS websites often operate globally, meaning they must comply with accessibility laws in multiple jurisdictions:

  • United States: ADA (Americans with Disabilities Act)
  • European Union: European Accessibility Act 2025
  • International standards: WCAG 2.1 Level AA

Tools like Scanluma can automatically scan your SaaS website for accessibility issues, so you know where you stand against WCAG. For more details, read: European Accessibility Act 2025: What Website Owners Must Know.

SEO and Visibility Benefits

Accessible SaaS websites rank higher on search engines. Features like clear headings, descriptive alt texts, and logical structure improve crawlability and indexing. For insights, see: 10 Common Accessibility Issues That Hurt Your Website’s SEO.

Enhancing User Experience and Conversions

Accessibility isn’t just legal—it’s good UX. Users with disabilities—and even those without—benefit from:

  • Clear navigation
  • Readable text and high contrast
  • Predictable interactive elements
  • Accessible forms and CTAs

Core Accessibility Best Practices for SaaS Websites

Use Semantic HTML and Logical Headings

Semantic HTML helps screen readers interpret your content correctly. Ensure headings are structured logically:

  • H1: Page title
  • H2: Section headings
  • H3: Sub-sections

Scanluma flags heading levels that skip and explains what needs to change. Proper structure improves SEO and accessibility simultaneously.

Ensure Keyboard Accessibility

Many users rely on keyboards or alternative input devices. Key best practices include:

  • Focusable elements for all interactive items
  • Logical tab order
  • Visible focus indicators

Scanluma flags some keyboard problems automatically, such as a tabindex that breaks the natural tab order. Test the full keyboard flow by hand as well.

Provide Descriptive Alt Text for Images and Icons

Alt text allows screen readers to describe images to visually impaired users. Tips for SaaS websites:

  • Describe the function of icons or graphics
  • Avoid generic phrases like “image” or “icon”
  • Include alt text for charts and data visualizations

Maintain Sufficient Color Contrast

Colors should have a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. This ensures readability for users with visual impairments. Scanluma checks the text on your pages and flags low-contrast combinations automatically.

Optimize Forms for Accessibility

Forms are a critical component of SaaS platforms. Make them accessible by:

  • Labeling all fields clearly
  • Ensuring proper tab order
  • Providing accessible error messages
  • Using ARIA attributes for complex components

Scanluma flags form fields without proper labels, so you know which forms need work.

Avoid Time-Based Restrictions

Timed sessions or auto-logouts should include:

  • Warnings for impending expiration
  • Sufficient time for completion
  • Option to extend session

This is particularly important for SaaS platforms with forms, reports, or analytics dashboards.

Consistency and Predictability in UI

Consistency reduces cognitive load and helps all users navigate your SaaS platform more easily. Maintain predictable locations for:

  • Buttons and menus
  • Form interactions
  • Notifications and alerts

Advanced SaaS Accessibility Tips

Use ARIA Roles Wisely

ARIA (Accessible Rich Internet Applications) roles provide extra semantic meaning for screen readers. Examples:

  • role="alert" for dynamic notifications
  • role="dialog" for modals

Avoid using ARIA unnecessarily. Scanluma flags invalid or misused ARIA attributes so you can correct them.

Optimize for Mobile Accessibility

SaaS platforms are increasingly used on mobile devices. Ensure:

  • Touch targets are at least 44x44px
  • Navigation is consistent across devices
  • Text scales without breaking layout

Test With Real Users

Automated scans are powerful, but real-world testing with users with disabilities uncovers issues tools might miss. Combine Scanluma’s scans with manual usability testing.
