Alt descriptions, popularly known as Alternative text or description, are used to describe the contents of an image or a picture within HTML code. It is generally a good practice to add Alt text to your images, as it helps search engines index images. Alt text can also help your SEO and makes images more searchable.

Example

For example, if you are putting up an article on your CRM and it has around five images. You should add a small alt text that perfectly describes what your image does, so even if it does not load, the user can understand the content.
