ADA compliance for a website refers to making sure that the website is accessible to people with disabilities, including those who are blind or visually impaired, deaf or hard of hearing, or have mobility impairments. This involves following the guidelines outlined by the Web Content Accessibility Guidelines (WCAG) 2.1, which are a set of technical standards for making web content accessible to people with disabilities.

To make a website ADA compliant, here are some steps you can take:

• Provide alternative text descriptions for images and other non-text content on your website.
• Ensure that all website functionality is available via a keyboard, as some users may not be able to use a mouse.
• Make sure the color contrast on your website is sufficient, so that users with visual impairments can easily distinguish between different elements on the page.
• Use descriptive and meaningful hyperlink text, rather than “click here” or similar phrases.
• Provide transcripts for videos and audio content, so that users who are deaf or hard of hearing can access the content.
• Use semantic HTML markup to ensure that the structure of the page is clear and easy to navigate.
• Make sure that your website is compatible with assistive technologies such as screen readers.

There are also various tools and services available to help you test your website for ADA compliance, such as WAVE and AChecker. It’s important to ensure that your website is accessible to all users, regardless of their disabilities, and making it ADA compliant can help achieve that goal.

Valid code is important not only for search engine optimization but also for website accessibility. When your website’s code is valid, it can help ensure that your website is accessible to users with disabilities, such as those who use screen readers or other assistive technologies to navigate the web.

Valid code can help ensure that your website’s content is properly structured and formatted, which can make it easier for users with disabilities to understand and navigate your website. For example, properly structured headings, lists, and other HTML elements can help users with screen readers navigate through your website’s content more easily.

In addition, valid code can also help ensure that your website is compatible with a wider range of devices and web browsers, which is important for both SEO and accessibility. When your website is compatible with a wider range of devices and browsers, it can improve your website’s user experience and accessibility, which can ultimately lead to higher search engine rankings and increased exposure for your business.

Overall, validating your website’s code is an important best practice for both SEO and website accessibility. By ensuring that your website’s code is valid and properly structured, you can improve your website’s visibility, user experience, and accessibility for all users, including those with disabilities.
