This refers to the written copy that appears in place of an image on a webpage if the image fails to load. It’s also used by screen-reading tools to describe images to visually impaired users. In the context of SEO, alt text plays a significant role in both accessibility and image optimisation.
Alt text helps search engines understand and index an image’s content and context, which can contribute to a website’s search engine ranking. When crafting alt text, it’s important to be descriptive and concise, accurately reflecting the content and purpose of the image while also incorporating relevant keywords when appropriate. This can enhance a website’s relevance in search results for those keywords, particularly in image search queries.
Good alt text improves the user experience, makes web content accessible to more people, and can also drive traffic to a website from image search results. It’s an essential aspect of both web accessibility standards and effective SEO practices.
