    Purpose and use

    Alternative text describes in words the non-text elements of a web page or document, such as photos, drawings or charts. You can add it as the form of an alt attribute and as captions. In WordPress, this is done through editing the image via your media library.

    Considerations

    From WebAim.org, alternative text is a textual substitute for non-text content in web pages.

    Alternative text serves several functions:

    • Screen readers announce alternative text in place of images, helping users with visual or certain cognitive disabilities perceive the content and function of the images.
    • If an image fails to load or the user has blocked images, the browser will present the alternative text visually in place of the image.
    • Search engines use alternative text and factor it into their assessment of the page purpose and content.
