Silktide and WCAG compliance

Silktide makes it faster and easier to improve your web accessibility compliance at scale, combining automated checks with straightforward tools to assist your team with any accessibility issues requiring human review.

Our checks cover accessibility guidelines from:

  • WCAG 2.0 (A, AA, and AAA levels)

  • WCAG 2.1 (A, AA, and AAA levels)

  • WCAG 2.2 (A, AA, and AAA levels)

What are automated and assisted checks?

Automated checks are great at catching straightforward issues, like missing descriptions for images or poor text color contrast, which are common barriers for people with disabilities.

When it comes to more nuanced aspects of a website — such as whether text alternatives convey the right information, or if a website's structure is logically presented — computer systems and automated checks can fall short.

This is where Silktide's "assisted" checks step in. They organize the relevant data for you in a way that speeds up the manual review process, making it easier to dive into and resolve those complex issues.

It's about striking a balance: leveraging automation for efficiency and relying on human insight for depth, ensuring websites are not just technically compliant, but genuinely accessible.

The importance of manual testing

Manual testing holds a crucial spot in ensuring websites are truly accessible. It adds a necessary layer of human insight, ensuring that websites are not only technically compliant, but genuinely usable and inclusive.

While automated tools do a stellar job at spotting many issues at scale, they can't fully grasp the human experience. That's where manual testing comes in — it's about putting yourself in someone else's shoes to understand how accessible a website really is. This process involves real people navigating a site as various users might, including those who rely on assistive technologies.

From checking if video captions make sense in context, to ensuring that a site can be navigated smoothly with keyboard commands alone, manual testing adds the human touch that technology alone can't replicate. It's not just about ticking boxes for compliance, it's about creating a web that's genuinely inclusive, where everyone can participate, learn, and connect.
