37. Why is image alt text important?
The alternative text – short alt text – is an attribute of the image tag in HTML code to describe the appearance and function of an image on a page. The computer algorithms search engines use to crawl the web can't see web pages like humans can see them. They can't just look at an image and know what's shown on it. They rely on math and code to get that context and information. This is why filling out the alt text attribute for each image on your website is important for SEO. It's also important for web accessibility and allows visually impaired users using screen readers to better understand images, too. Alt text also will be displayed in place of an image if an image file cannot be loaded.
