Alt text primarily serves to make online content more accessible to individuals with disabilities, particularly those with visual impairments. When a screen reader encounters an image, it relies on Alt text to describe the image, making it possible for users to understand the visual elements on a webpage.
Beyond accessibility, Alt text holds significant SEO benefits. Search engines like Google use Alt text to understand the content of images, which can influence your page’s ranking in search results. Properly optimized Alt text can drive more organic traffic to your website.
Alt text provides a textual representation of an image or other non-text content, ensuring that users who can’t see the image can still comprehend its context. It’s like painting a vivid picture with words, making your content more engaging and informative.
