Website Terminology Glossary
Alt text, or alternative text, is a description of an image that is used to provide context and information about the image for users who are visually impaired or who have images turned off in their web browser. Alt text is also used by search engines to understand the content of images on a webpage.
Alt text is added to an image in the HTML code using the “alt” attribute. It is NOT an HTML tag in itself. The alt text should be a concise and accurate description of the image, and should provide enough information to convey the image’s purpose and content. Alt text should also be written in plain language and avoid using unnecessary technical terms or jargon.
Some examples of alt text for images include:
A photo of a dog
A golden retriever playing catch with a tennis ball in a grassy field.
A chart or graph
A bar graph showing the sales figures for Q1, Q2, Q3, and Q4 of 2021.
The Coca-Cola logo, featuring a red and white script font on a white background.
A hand-drawn sketch of a bicycle with a basket on the front, surrounded by flowers.
Alt text is an important part of web accessibility and helps ensure that all users can access and understand the content of a webpage, regardless of their abilities or technology preferences.
