Why Image Optimization Matters for SEO

Accessibility

Alt text helps visually impaired users understand your images. Missing alt text is a WCAG accessibility violation that can lead to compliance issues.

Image Search Rankings

Google uses alt text to understand and rank images. Missing or poor alt text means your images won't appear in Google Image Search results.

Page Speed

Broken images can cause layout shifts (bad CLS) and slow page rendering. Finding and fixing broken images improves Core Web Vitals.

User Experience

Broken images make your site look unprofessional and untrustworthy. 60% of users say they wouldn't buy from a site with broken images.

Why Broken Images Hurt Your SEO and User Experience

Broken images on your website do more than create an ugly visual experience - they actively harm your search engine optimization. When an image fails to load, it triggers a 404 error on that asset, wasting crawl budget and creating a negative signal for search engines.
