The term "ALT text" refers to the "alternative text" that is utilised inside of an HTML code to describe the purpose of a picture which is displayed on a page. A improved consumer perception can be achieved by including alt text alongside your images.
Even though search engines are unable to understand photographs, users often base their understanding of a website on the pictures it contains. Alt tags are a solution to this problem since they provide language that can be read by search engines.
Images play a critical role in how humans understand a web page, but search engines and other robots cannot do so. This problem is solved by using alt tags, which provide text crawled by search engines.
