What is the purpose of using alternative texts in images?
Alternate Texts, also known as Alternative Descriptions or simply Alt Tags help in better crawling and indexing of images on your website. By default, Google’s crawl bot cannot understand images. It needs guidance to help understand what the image is about. Alt Texts help Google bot to understand what the image is displaying. Besides this, people with visual imparity also benefit from these as they can understand the text in Braille but cannot see an image.
