Everything can be SEO, and certainly the targeted and conscious use of images can make any content more interesting and appealing, helping readers understand the topic better than using only the textual part. In particular, images add value to our SEO efforts by increasing user engagement and site accessibility. Indeed, it is not enough to ensure that images load quickly or are visually appealing, but we must also work to make them accessible to all users, including those who use screen readers due to visual impairments. Alt text, or alternative text, plays a key role in this context, and so we focus precisely on alt text and filename to find out what they are, how they differ, and best practices to put into practice for their management.

What is the alt text of images

Alternative text or alt text is a short written description that is provided as an attribute in HTML images.

Leaving aside the linguistic aspect, alt text is a textual string that is used to describe an image to “alternative” sources and to ensure maximum accessibility of resources, according to W3C guidelines, which call for text that does not have to “necessarily describe the visual characteristics of the image itself, but convey the same meaning as the image.”

In fact, this text has the primary purpose of describing the image and its context, serving as a substitute if the image cannot be displayed.
