What is “Alt Text”?

Many don’t know the answer to this question. Alt text is a tag – an essential component for optimising content in search engines. Many websites neglect them because they don’t understand how they work. After reading this article, you should have a good understanding of what alt tags are and how to use them.

Let’s start at the beginning.

The term “alt text” is an abbreviation of alternative text. Whenever you have an image in your text, the alt text describes it.
For instance:

  • A user with a screen reader will hear the alt text of the image
  • A text browser will display the alt text instead of the image
  • A graphics browser will display only the image. It displays the alt text only if the user has configured the browser not to display images, or if the browser was not able to retrieve or to decode the image

Search engines use algorithms to review the text on your website. Without alt text, they are not able to understand image content. Your images will be considered generic content, thus resulting in lower rankings in search engines.
