Alt tags, or alternative text, are descriptions added to the HTML code of an image to describe its content. Originally designed to assist visually impaired users by providing context through screen readers, alt tags have since evolved to serve a dual purpose: they also provide search engines with valuable information about the image content, helping it appear in relevant image search results.
Alt tags play an essential role in image search optimization and overall SEO by providing context for search engines and enhancing accessibility for users. By implementing best practices for alt tags, websites can improve their search visibility, drive more traffic, and create a better user experience. Whether for product images, informational graphics, or decorative visuals, well-optimized alt tags are a valuable component of any SEO strategy.
