How To Use Alt Text

How to Use Alt Text for Images

Alt text is an essential component of website accessibility. It provides a text alternative of the image content, which makes it possible for people with visual impairments to understand images on a webpage. In addition, alt text is also important for e-commerce sites and helps search engines understand the content of the website for better ranking. In this article, we will look at how to use alt text for images.

1. Define the purpose of the image

Before you begin writing alt text, it is important to understand the purpose of the image. Ask yourself, what is the image trying to convey? Does it have any textual content that needs to be replicated in the alt text? Make sure your alt text is relevant to the image and provides a textual version of the information conveyed by the image. Keep it concise and to the point.

2. How to write alt text

When writing alt text, keep it descriptive, concise and meaningful. It should be no longer than a sentence or two. Start with a brief description of the image, and then provide more detail about the image or its purpose. Avoid using vague phrases such as “image of” or “picture of”. Instead, use specific descriptions such as “man walking a dog in the park” or “woman reading a book by the fireplace”. Also, avoid using the file name of the image as the alt text.

In addition, alt text should not contain any information that is redundant with the surrounding text, such as captions or headings. If the image is purely decorative, then an empty alt attribute should be used, such as alt=””. This tells assistive technologies that the image is not important for understanding the content of the page.

In conclusion, alt text is a vital component of website accessibility and has multiple benefits such as improved SEO and better user experience. By following these guidelines on how to use alt text, you can ensure that your website is more accessible and inviting for everyone.
