To audit images for SEO and performance, analyze single pages or full-site audits to detect missing alt text, oversized files, outdated formats, missing dimensions, and lazy-loading mistakes. This produces a prioritized remediation report with estimated savings and implementation guidance.

Missing image width and height causes cumulative layout shift risks because the browser cannot reserve adequate space before the asset loads. Auditing flags images without dimensions or aspect-ratio styles and provides remediation to prevent layout shifts.

The best way to write alt text for SEO is to ensure attributes are meaningful and concise. Alt text analysis detects missing or non-descriptive alt attributes and suggests descriptive alternatives to improve search visibility and accessibility.

You need to use WebP format and responsive srcset attributes when file size checks flag images exceeding target thresholds. Auditing recommends modern formats like WebP or AVIF with fallbacks and verifies presence of srcset and sizes for responsive loading.

To fix lazy-loading mistakes and fetchpriority for LCP images, auditing verifies proper lazy-loading for below-fold images and checks fetchpriority for LCP assets. It also validates decoding attributes for non-LCP assets to ensure optimal loading.

You can run an image optimization audit for ecommerce product pages or content-heavy blogs. The audit evaluates images against size and format thresholds to reduce LCP, improve accessibility, and cut image bandwidth.
