You can audit image SEO by analyzing rendered <img> elements to identify missing alt text, inefficient formats, oversized assets, and loading issues. This generates a prioritized optimization list by potential savings and clear recommendations for fixes.

To check if images cause CLS, audit the HTML for missing width and height attributes or CSS aspect-ratio properties. Preventing CLS requires explicitly defining image dimensions to reserve space before the asset loads fully.

Fix lazy loading LCP issues by auditing image fetchpriority and loading attributes. Non-LCP images should use lazy loading and async decoding, while LCP images require eager loading and high fetchpriority to load faster.

The image audit checks for WebP and AVIF format recommendations by reviewing your current format choices. It flags inefficient formats and suggests modern alternatives alongside responsive image attributes like srcset and sizes.

You can use this image audit on any public or accessible URL where images are rendered in HTML as <img> elements. It validates alt text presence, descriptive wording, keyword use without stuffing, and recommended length.

File size thresholds for oversized images are tiered by image type, categorizing assets as thumbnails, content images, or hero images. The audit flags assets exceeding these specific thresholds and recommends compression targets.
