ALT attributes, also known as “ALT tags” or “ALT texts,” are an essential aspect of web development that provide textual alternatives for images on a webpage. These attributes play a crucial role in improving web accessibility, particularly for users who rely on screen readers to navigate the internet. Additionally, ALT attributes contribute to SEO (Search Engine Optimization) by allowing search engines to better understand and index the content of images.
Two types of errors can occur with ALT attributes: they may be entirely missing, or there may be an ALT attribute, but it’s not appropriate (e.g., image-name.jpg).
You can primarily manage the ALT attributes in the WordPress media library, where you can set a unique ALT attribute for each image. It’s advisable to provide as descriptive and characteristic text as possible for the image, in a way that also supports SEO.
Please note that you may need to reinsert the image after setting the ALT tags for the changes to be reflected on the site.
