When you upload an image to your website, Google and screen readers can’t “see” what’s inside the picture. This is where the 📖 What is Alt Tag? question comes into play. The alt tag (or alt text) is a short description added to an image in your website’s HTML code. Its main job is to describe the image so both search engines and visually impaired users understand what’s shown.
Adding a proper alt tag is not just a technical trick; it’s a smart move for SEO, accessibility, and user experience.
