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.

What do website accessibility checkers check for?

Website accessibility checkers come in a variety of formats, from comprehensive, paid-for tools, to free web page scanners.

Siteimprove’s Website Accessibility Checker is a free, automated checker. Using the same algorithm as Siteimprove’s paid-for Accessibility platform, it helps you identify 15 common accessibility issues – with no subscription or installation required. Every check adheres to WCAG standards, so you can use it as a starting point for identifying and fixing accessibility issues across all internationally-recognized conformance levels.

Simply enter your email to receive your free diagnosis and explanations for where your website fails to meet WCAG standards. Input your desired URL to receive:

  1. An instant overview of your website’s accessibility issues
  2. Your personalized accessibility score, based on 15 Siteimprove Accessibility checks. This score can be shared across your organization as an easily-understandable point of reference when it comes to your accessibility status
  3. Clear explanations of how each identified issue affects your website visitors and impacts the user experience

Siteimprove’s Accessibility Checker scans your website for these common accessibility blockers that indicate that your website isn’t compliant with both US and international accessibility laws:

  • Image with no alt attributes
  • Image link is missing alternative text
  • Input field has no description
  • Text area has no description
  • Select box has no description
  • Webpage has multiple title elements or no title element
  • Webpage title is missing text
  • Heading is missing text
  • Alternative text for the image is a file name
  • Element ID is not unique
  • Form control label is missing text
  • Use of automatic redirect after a time delay
  • Language of page has not been set
  • WAI-ARIA image is missing alternative text

Remember, these are just a small selection of the accessibility issues that Siteimprove’s full Accessibility Platform audits your website for.

Why you should use one

Inaccessible websites create barriers for all your website visitors, not just people with disabilities. But before you can begin fixing accessibility problems, you need to know what – and where – they are. Using an automated website accessibility checker is an efficient way to check a website’s accessibility status and begin your journey towards accessibility compliance.  

Your visitors rely on the usability of your website to engage with your brand. In the EU, one in four people live with a disability, and in the US, that figure is 56 million. Poorly designed, inaccessible pages make it difficult for these groups to use your website. Simply put, if your website is not accessible, you are excluding a significant percentage of the global population, which not only threatens disabled people’s rights, but can also have severe consequences for your organization.

The internet features a wide range of testing tools and software programs for web accessibility evaluation. While some companies might be reluctant to invest in a dedicated web accessibility tool, the fact is that creating and maintaining accessible web content in the modern era is too large and difficult a task to be done without automated accessibility test.

Fortunately, accessibility tools, like Siteimprove, allow you to tackle the WCAG 2.0 A, AA, AAA barriers that hurt your site experience and brand reputation. Manually auditing hundreds – or even thousands – of pages across your website for accessibility issues takes time, resources, and expertise. Thankfully, website accessibility checkers take care of the heavily lifting, allowing you to check your website’s accessibility status instantly and prioritize pages that need attention with confidence. 

That doesn’t mean that manual accessibility testing is a bad idea—in fact, manual testing is an integral part of accessibility testing as not everything can be automated. Automation is a great, cost-effective (you could argue it’s the only financially viable way) for covering large amounts of content quickly whereas manual testing is great for a thorough investigation into a smaller amount of content.

How do I make the best use of the website accessibility checker?

Website accessibility checkers like the Siteimprove Accessibility Checker have been designed to make working towards accessibility compliance simple. Here’s a step-by-step guide on how to perform a website accessibility check:

  1. Enter the URL for the website you want to check into the checker form.
  2. Add your email to get your website accessibility results into your inbox – and on-screen – within minutes. You can then share your accessibility checker report with your wider team.
  3. Check your unique accessibility score. This score is based on the 15 accessibility checks and helps you get a clear idea of how accessible your website is.
  4. Review your website’s accessibility issues and errors in detail. Click on the question mark next to each issue for a deep dive into how it impacts your website’s accessibility level and user experience.
  5. Request a demo to see what other accessibility issues are present on your website, based on Siteimprove Accessibility’s entire range of checks.

Armed with these insights you will be in a good position to start your journey towards accessibility compliance. Use your personalized accessibility score and the list of confirmed accessibility issues as a first step to get your team on board with making your website digitally inclusive. Next comes a more comprehensive accessibility audit, remediation of the errors detected, and setting up an ongoing accessibility compliance monitoring strategy. 

Should I make all of my accessibility testing automated?

To put it simply, no. For all of the advantages of running regularly scheduled automated accessibility tests, any healthy website should also include manual testing in its plans. There are a number of areas where an actual human can determine accessibility issues that an automated tool may not recognize.

Areas, where manual accessibility testing is preferable, include ensuring that all facets of a page can be accessed with keyboard-only navigation, detecting color contrast issues that make pages difficult for some users to read, checking HTML5 and WAI-ARIA elements for coding best practices, and testing compatibility with leading screen readers.

The bottom line is that testing website accessibility regularly and thoroughly is a must in today’s online environment. With the advent of WCAG 2.1 and other accessibility regulations and an ever-growing number of seniors relying on the internet, offering a website experience with equal access for all users is more important than ever.

Whether your organization is new to the world of accessible content or looking to improve on your current approach, a well-considered combination of manual and automated accessibility testing with a tool like Siteimprove Content & Accessibility will go a long way toward keeping your website usable for everyone who needs it.
