To audit images for SEO and performance, you need to analyze page elements like alt text, file size, format, responsive sizing, and lazy loading. This requires extracting webpage assets and evaluating them against optimization criteria to identify missing tags or oversized files.

Preventing CLS requires checking that images have proper dimensions and aspect ratios defined in the markup. An image audit validates these attributes to ensure the browser reserves space, stopping layout shifts from occurring during page rendering.

Assessing image file sizes involves evaluating the byte weight of image assets and comparing them against target sizes for their specific category. This analysis identifies oversized files that slow page load and suggests appropriate format recommendations for compression.

Yes, you can check alt text relevance and responsiveness for images in local files by running an analysis script on the file path. The process extracts image elements and evaluates the descriptive quality of alt tags and responsive source sets.

Lazy loading validation targets images below the fold to defer off-screen loading. Proper implementation checks ensure above-the-fold images load immediately for performance, while lower viewport images use lazy attributes to save bandwidth.

Optimal image formats depend on the specific use case, balancing quality and file size. An image audit advises on the most appropriate formats for different contexts, ensuring images are correctly formatted for both performance and SEO rankings.
