Manual Accessibility Testing
Automated testing is very important, however, keep in mind that automated testing alone will not make your website ADA compliant. For example, an automated tool can identify that alternative text exists for an image but cannot determine if the alternative text is appropriate. These items will be identified by Siteimprove under the Potential Issues Section. In addition, there are other accessibility barriers automated testing can't identify. For that reason, it is equally important to manually test content and functionality of site components and forms.

Multimedia, Animations and Motion
Design for Readability
Avoid underlining text that isn't a link as many users see an underline and try to click on it thinking it is a link.

WAI-ARIA
WAI-ARIA (Web Accessibility Initiative - Accessible Rich Internet Applications) is a set of technical specifications developed by the World Wide Web Consortium (W3C) to enhance the accessibility of web content and applications. It provides a way to add additional semantics to HTML elements, enabling better communication between web browsers and assistive technologies.

Testing Reading Order
By combining the methods below, you can thoroughly assess and ensure a logical and intuitive reading order, enhancing the overall accessibility of your digital content.
Headings Structure Review
Check that the heading structure of your content follows a logical hierarchy. Screen readers often use heading levels to create an outline of the page, so a proper structure contributes to a logical reading order.
Visual Inspection
Manually inspect the visual layout of your page to identify any anomalies in the reading order. Ensure that content is presented in a logical sequence visually, as it often corresponds with the reading order.
Tab Order Testing
Use the keyboard to navigate through the interactive elements on your webpage. Ensure that the tab order follows a logical sequence and that there is a visual indicator of where you are when tabbing. This helps identify if users can navigate through your content in a meaningful order.
Screen Reader Testing
Use screen reader software such as JAWS, NVDA, or VoiceOver to navigate through your content. Listen to the content as it's read aloud, ensuring that the order is logical and makes sense in the absence of visual cues.
