What does Image SEO Auditor do?
The Image SEO Auditor crawls image references, validates fetch health, and checks alt-text quality patterns. It helps teams improve image discoverability, accessibility, and page efficiency.
Why it matters for SEO: Images drive traffic through Google Images search, improve accessibility scores, and directly affect Core Web Vitals performance. Missing alt text hurts both search visibility and WCAG compliance.
Accessibility Compliance: Audit all images for missing or low-quality alt attributes to meet WCAG 2.1 guidelines and improve screen reader experiences.
Page Speed Optimization: Identify oversized images and missing lazy-loading attributes that inflate LCP times and degrade Core Web Vitals scores.
