On-Page SEO

Alt text (alternative text) is an HTML attribute on image tags that describes the image content. It serves two purposes: accessibility for screen readers and context for search engines that cannot "see" images. Alt text should describe the image meaningfully, not be stuffed with keywords.

Why it matters

Alt text improves accessibility and helps images appear in image search results.
