What is a website accessibility checker?
A website accessibility checker is a digital tool you use to quickly scan your website for on-page and technical accessibility issues and errors. These insights can then be used as a starting point for bringing your website in line with recognized accessibility standards, like the Web Content Accessibility Guidelines (WCAG). Website accessibility checkers are also a useful tool for preventing violations of US accessibility legislation, like the Americans with Disabilities Act (ADA) and Section 508 of the Rehabilitation Act.
Additionally, accessible websites provide a better experience for everyone and can even boost your search engine optimization. User experience is about to become even more important with Google’s Core Web Vitals algorithm update rolling out in May 2020, so there’s never been a better time to ensure your website provides an accessible, user-friendly experience.
How does it work?
An accessible website is key to creating a great user experience for all your site’s visitors. The Siteimprove Website Accessibility Checker scans your web page for accessibility issues using the Web Content Accessibility Guidelines (WCAG) international standard recognized by most governments and legislation. For more details on how we calculate your score, see our sample page below.

Tap into a wider market
How many potential customers are you missing out on right now? Critical accessibility issues make your website unusable to 20% of the world’s population with a disability. And as older generations age, they experience vision and hearing loss that affects their ability to navigate websites. Prioritize accessibility issues and be a first mover in an untapped market.

Protect your business from legal backlash
An accessible website is no longer a nice-to-have, but a must. Lawsuits related to web accessibility are on the rise and you can expect increased regulations as accessibility laws catch up with technology. Start fixing your website’s accessibility issues and you can lower your risk of costly legal issues and damage to your brand’s reputation.

Improve your customer experience
Boost your customer experience across the board with web accessibility. Too many pop ups, hard to read font, unclear content, and complicated purchasing flows make it difficult for everyone to navigate your website. Start building with accessibility in mind and you can create an easy-to-use website leading to happy customers who come back for more.
