What is the Use of ALT tag in Websites?

[sudeepkhana]

Alt text is an important yet occasionally overlooked part of making a site accessible to all users.
It is a simple bit of HTML code that essentially describes an image that appears on a webpage so that the user still knows what the image represents if they are visually impaired or if the picture simply doesn’t display correctly.
The alternative attribute can be input within the ‘alt text’ or ‘alt tag’ of the image element and the exact wording used depends on the context of the image as much as the content itself.
An additional benefit is that it provides a semantic description of images for search engines. This can attract additional traffic through Google Images and has a positive impact on SEO.
