Image Issues
About Image SEO
Images account for roughly 60% of total page weight on the average website and are directly responsible for the majority of Largest Contentful Paint (LCP) failures — a Core Web Vital that Google uses as a ranking signal. Beyond performance, images represent an enormous organic traffic opportunity: Google Images drives approximately 22% of all web searches, and AI-powered visual search platforms like Google Lens are growing rapidly. Yet image optimization remains one of the most neglected areas of SEO. Common oversights include missing alt text (which affects both accessibility and keyword relevance), serving uncompressed PNG files when WebP or AVIF would reduce payload by 50-80%, and failing to implement responsive srcset attributes for different viewport sizes. This reference covers every image-related issue Digispot AI identifies, from critical accessibility violations like entirely missing alt attributes to performance-focused recommendations around lazy loading, CDN delivery, and next-gen format adoption. Fix these issues and you'll improve both your page speed scores and your visibility in image search results.
