How To Write Alt Text For Images

Writing alt text for images is an essential element in creating an inclusive and accessible website. Alt text is a short description of an image that appears in place of the image when it cannot be displayed. Alt text is used by screen readers for people who are blind or visually impaired to understand the content on the website. In this article, we’ll provide an insight into how to write alt text for images.

1. Be descriptive: The purpose of alt text is to provide a clear and concise description of an image. As such, it is essential to be specific and descriptive. Use accurate and concise language to describe what the image is all about. Also, consider the image’s context and function on the page, then use this information to add details to the alt text.

2. Keep it brief: While it is important to be descriptive, it is equally important to keep the alt text as brief as possible. Most screen readers and other assistive technologies only read up to 125 characters of alt text. Therefore, make sure your alt text is no more than 125 characters long.

3. Avoid overusing keywords: Alt text should not be used to stuff keywords or spam the content. Alt text is about describing an image, not optimizing for search engines. Therefore, avoid using irrelevant, spammy or repetitive keywords. Instead, focus on providing a quality description that accurately describes the image.

4. Use appropriate punctuation: When writing alt text, use appropriate punctuation, such as commas or periods, to break up your description into smaller phrases. This helps to make the alt text easier to read and understand.

5. Don’t forget decorative images: Not all images need alt text. Decorative images that do not add meaning or context to the content should have an empty alt attribute. This tells screen readers that the image is decorative and helps to avoid confusion.

In conclusion, alt text is essential for creating an accessible website. Follow the tips outlined above to write effective alt text for your images. Remember to be descriptive, keep it brief, avoid overusing keywords, use appropriate punctuation and don’t forget decorative images. By incorporating these best practices, you can improve your website’s accessibility and make it more inclusive for all users.
