A Beginner's Guide to Web Design & Development: Enhancing Accessibility

---

For those venturing into the realm of web design and development, understanding the nuances of accessibility is a must. This extends beyond just creating visually pleasing websites; it's about ensuring your site is usable for everyone. Web accessibility isn't just an inclusive practice; it also improves your SEO efforts, enhancing your website's visibility on search engine results. So, let's explore what web accessibility entails, the common terms, best practices, and the resources to help create websites that everyone can use.

What is Web Accessibility? Making Sense of the Basics

At its core, web accessibility makes your websites available to as many people as possible. This includes users with disabilities like visual, auditory, cognitive, neurological, or physical impairments, who may interact with the internet differently.

But remember, web accessibility isn't just for individuals with disabilities. It caters to a broader audience - from mobile device users to senior individuals and those with temporary impairments like a broken arm. Ultimately, incorporating web accessibility enhances user experience and boosts your website's SEO ranking.

Understanding Web Accessibility Jargon

Before we dive into the web accessibility practices, let's get familiar with some common terms:

• Web Content Accessibility Guidelines (WCAG): These are a set of standards designed to make web content more accessible. They're based on four principles: content must be Perceivable, Operable, Understandable, and Robust (POUR).

• Accessible Rich Internet Applications (ARIA): ARIA comprises a set of attributes for making web content and applications more accessible, particularly for dynamic content and advanced user interface controls.

• Americans with Disabilities Act (ADA): This US law mandates all websites be accessible to people with disabilities.

Web Accessibility Tools for Enhanced SEO

Several tools can evaluate whether your website meets accessibility standards. Here are a few:

• Web Accessibility Evaluation Tool (WAVE): WAVE is a free tool that identifies accessibility issues on your website, ultimately improving your site's SEO.

• Google Lighthouse: This open-source tool checks accessibility, performance, SEO, and more to optimize your site's visibility.

• Axe: This suite of accessibility testing tools includes browser extensions and APIs.

• NonVisual Desktop Access (NVDA) and Job Access With Speech (JAWS): These screen readers simulate the experience of visually impaired users, helping optimize your site for enhanced accessibility and SEO.

Best Practices and Checklists: Creating Accessible and SEO-friendly Websites

While creating an accessible website might seem challenging, adhering to a few key principles and best practices simplifies the process.

For Designers:

1. Semantic HTML: Use appropriate tags for the job to help assistive technology understand and present your content efficiently.

2. Color and Contrast: Ensure that the color contrast ratio between text and background is at least 4.5:1 for regular text, enhancing readability and SEO.

3. Keyboard Accessibility: Ensure all functionalities are accessible via a keyboard.

4. Avoid Automatic Media and Navigation: Avoid elements that start automatically, as they can be confusing and impact user experience and SEO.

5. Alternative Text for Images: Alt text helps screen readers describe images to visually impaired readers, improving accessibility and boosting SEO.

For Developers:

1. ARIA: Use ARIA roles and properties when necessary. They can improve accessibility, but remember not to use them if not needed.

2. Forms Accessibility: Properly label forms and ensure all form controls are accessible via keyboard.

3. Accessibility Testing: Regularly test your site's accessibility using the mentioned tools and address identified issues, contributing to better SEO.
