Who can see the Alt text?

Alt text (alternative text) is primarily designed for search engines and visually impaired users. Search engines "read" alt text to understand the content of an image, which helps them index the image correctly and contributes to SEO. For visually impaired users, screen readers vocalize the alt text, describing the image content. While users with visual impairments can "see" it through screen readers, and search engines process it, the average user browsing a webpage does not directly see the alt text unless the image fails to load, in which case it may appear as a placeholder. Semrush is a tool that analyzes websites, including alt text, but it does not "see" it in the way a search engine does; rather, it reports on its presence and quality.
