What Is Alt Text For Images

What is Alt Text for Images?

Alt text, also known as alternative text or alt tags, is a short and concise description of an image that’s used to describe the image’s content and purpose to users who may not be able to see it. Alt text is essential for web accessibility and usability, as it enables individuals with visual impairments or other disabilities to understand the content of an image through assistive technologies such as screen readers, which read the text aloud.

Alt text also serves as a backup for when the image is unable to load or when there’s an error in the image’s source code. In such cases, the alt text will be displayed instead of the image, ensuring that the user still receives the intended information.

Why is Alt Text Important for SEO?

Aside from its importance in web accessibility and usability, alt text also plays a crucial role in search engine optimization (SEO). Since search engines’ crawlers can’t “see” images and rely on text to understand the content of a webpage, alt text provides a way for search engines to understand what an image is about and how it’s relevant to the content on the page.

Proper use of alt text can also help improve the webpage’s search engine ranking and visibility, as search engines consider alt text as a part of the webpage’s content. It’s important to note, however, that alt text should be descriptive and relevant to the image, and not stuffed with keywords or used for spammy purposes, as this can harm the webpage’s SEO.

In conclusion, alt text is a crucial element to consider when publishing content on the web. By providing accurate and descriptive alt text for images, you can improve web accessibility, ensure the intended information is received even in case of technical issues, and boost the webpage’s search engine ranking and visibility.
