What Is Alt Text

What is Alt Text?

Alt text stands for alternative text, which is a description of images, videos, or any other non-textual content on a web page. The purpose of alt text is to provide a textual alternative to non-textual content for individuals who cannot see or access the content. Alt text is used by screen readers and other assistive technologies to describe the content to the users. It is also used by search engines to understand the content of a page.

Why is Alt Text Important?

Alt text is essential for accessibility and usability of web content. Individuals who cannot see or access the content rely on assistive technologies such as screen readers to read the content aloud. If the content is not described using alt text, it will not be accessible to these individuals. Moreover, search engines use alt text to understand the content of a page and rank it in search results. Pages with descriptive and relevant alt text are likely to rank higher in search results, which can increase the visibility and traffic to the website.

How to Write Effective Alt Text?

Writing effective alt text is important to ensure accessibility and usability of web content. Here are some tips to write effective alt text:

1. Be Descriptive: Alt text should be descriptive and relevant to the content. It should accurately describe the content, context, and function of the non-textual content.

2. Keep it Concise: Alt text should be concise and to the point. It should not be too long or too short. A good rule of thumb is to keep it under 125 characters.

3. Use Keywords: Use relevant keywords in alt text to help search engines understand the content of the page. However, do not stuff it with irrelevant or excessive keywords.

4. Avoid Redundancy: Avoid repeating the same alt text for multiple images or videos on the same page. Each piece of non-textual content should have a unique and descriptive alt text.

In conclusion, alt text is an essential element of accessible and usable web content. It enables individuals who cannot see or access the content to understand it through assistive technologies. Moreover, it helps search engines understand the content of the page and rank it in search results. Writing effective alt text is crucial to ensure accessibility and usability of web content.
