What is Alt Text?

It serves as a textual alternative to images for users who are unable to view them, such as those using screen readers or those with slow internet connections. Alt Text is also used by search engines to understand the content and context of images, which can impact the website’s visibility in search engine results.

Characteristics of Alt Text

Descriptive: Alt Text should accurately describe the content and purpose of the image, providing users with relevant information even if they cannot see the image.
Concise: Alt Text should be concise and to the point, conveying the essential details of the image in a brief description.
Informative: Alt Text should provide valuable context about the image, including relevant details such as objects, actions, and emotions depicted in the image.
Relevant Keywords: Alt Text can include relevant Keywords related to the content of the webpage and the image itself, which can help improve the webpage’s search engine ranking.
