Alt text
What is "Alt text"?
"Alt text" is short for "Alternate text," which means " Alternative text " in English.
Alternative text is a property of an image inserted into a web page, email, or any other HTML-coded document.
In more technical terms, we're talking about...attribute "alt" of the tag which displays the image.
old='alternative text for the image' />
This is how the HTML markup language describes images in this type of document.
And, indeed, it stipulates that the images will systematically be accompanied by a description in text form.
This "alternative text" for the image therefore has two main purposes:
– that of displaying alternative text when the image cannot be displayed correctly on the page
– that of providing a textual description of the image to browsers for accessibility reasons (voice reading for the visually impaired, etc.)
– and also to indicate precisely to search engines what the image contains for reasons of semantics and content indexing.
Every web designer knows this: you must never forget to include alternative text for images on web pages. A well-written alt text translates to better accessibility and improved SEO ranking.
