Explaining WCAG principles: Understandable & Robust

In today's digital age, it's crucial for websites to be accessible to all users, regardless of their abilities. This is where the Web Content Accessibility Guidelines (WCAG) come into play. WCAG provides a set of principles and guidelines to ensure that web content is perceivable, operable, understandable, and robust. In this article, we will focus on two specific principles: Understandable and Robust.

Understandable Guideline: Readable

One of the key aspects of making web content understandable is ensuring that it is readable. Users should be able to easily comprehend the information presented on a website without facing any hurdles. To achieve this, web developers can follow best practices provided by the Plain Language Action and Information Network (PLAIN).

Plain language is all about making the content clear and straightforward. It involves using strong and simple words, breaking down information into short paragraphs, and organizing it in a coherent manner. Additionally, adopting a conversational tone can make the content more relatable and easier for users to understand.

Guideline: Predictable

Another aspect of making web content understandable is ensuring that it is predictable. Users should be able to anticipate how the website will behave and navigate through it with ease. This can be achieved by following guideline 3.2 of WCAG.

Predictability can be enhanced by writing valid and clean HTML code using correct semantics. By adhering to proper coding practices, developers can ensure that the website behaves as expected across different devices and platforms. This not only improves the user experience but also makes the website more accessible to individuals with disabilities.

Robust Guideline: Compatible

In addition to being understandable, web content should also be robust. Robustness refers to the ability of a website to adapt and function properly across different technologies and assistive devices. Guideline 4.1 of WCAG focuses on compatibility.

To ensure compatibility, web developers should strive to write clean and valid HTML code. By following coding standards and best practices, developers can ensure that the website functions correctly on a wide range of browsers and devices. This is particularly important for individuals who rely on assistive technologies to access and navigate websites.

Connecting the Principles

While the principles of Understandable and Robust may seem distinct, they are interconnected in their goal of creating an accessible web experience. By making web content readable and predictable, developers can enhance its understandability. Similarly, by ensuring compatibility, developers can make the content accessible to a broader range of users.

It's important to note that achieving product/market fit is not solely dependent on creating a product that is 10 times better than its competitors. While this concept, popularized by Peter Thiel, emphasizes the need for significant improvement, it's not a one-size-fits-all approach. Different users have different needs and thresholds for switching to a new product.

For example, Amazon initially focused on selling books online because it was easier to create maximum added value compared to brick-and-mortar retailers. By offering a much larger selection of books than traditional bookstores, Amazon provided a compelling reason for users to switch to their platform.

Similarly, the added value of a product can vary significantly across different use cases and user segments. A product may achieve product/market fit in certain segments but not in others. Therefore, it's crucial to understand the context and needs of the target audience to maximize the chances of achieving product/market fit.

Actionable Advice:

1. Prioritize readability and predictability in your web content. Use plain language, short paragraphs, and a conversational tone to make it easier for users to understand. Ensure that the website behaves as expected and is easy to navigate.

2. Write clean and valid HTML code to enhance the compatibility and robustness of your website. This will ensure that it functions correctly across different browsers and devices, making it accessible to a wider range of users.

3. Understand the specific needs and preferences of your target audience. Different users have different thresholds for switching to a new product. By offering added value that exceeds the switching cost, you can increase the chances of achieving product/market fit.

In conclusion, the principles of Understandable and Robust are essential for creating an accessible web experience. By focusing on readability, predictability, compatibility, and addressing the specific needs of users, web developers can enhance the overall user experience and increase the chances of achieving product/market fit.
