Paste HTML to find images with missing or empty alt text
Alt text helps search engines understand image content, improves accessibility for screen readers, and appears when images fail to load. Google uses alt text as a ranking signal for image search results.
Good alt text is descriptive, concise (under 125 characters), includes relevant keywords naturally, and accurately describes the image content. Avoid starting with "image of" or "picture of".
Decorative images should use empty alt attributes (alt="") to tell screen readers to skip them. Missing alt attributes entirely is an accessibility violation.
