When should you not use alt text?
3. Including alt text for decorative images or items. Decorative items such as dividers or design items that don't provide additional context or content don't need alt text. They don't add to the information a user needs and they make little sense, or are unnecessary, when read with a screen reader.
Is alt text useful?
Alt text improves digital accessibility
more accessible to people with disabilities. Although just the presence of alt text in the HTML code doesn't ensure that a given image is accessible (because the accuracy and specificity of alt text also matter), it certainly is better than having no alt text at all.
Should I add alt text to all images?
Don't add alt text to every image.
You should add alt text to most images on a webpage for the sake of SEO, UX, and accessibility — however, there are exceptions. Images that are purely decorative or are described in text nearby, for example, should have an empty alt attribute.
What is a good image alt text?
Images as Links: If the image is being used to link to another page, the alt text should describe what will happen when the image is clicked (rather than what it looks like). For example, the alt text for an image of a question mark that links to a help page should be “Contact Support” rather than “question mark.”
