Image optimization
Image optimization combines weight reduction, modern formats (AVIF, WebP), appropriately sized dimensions, and semantics: filename, alt text, caption. It serves speed, accessibility, and visual search simultaneously.
In practice
Weight first: images are the primary source of slowness on ordinary pages — compression and lazy loading address the bulk of it. Semantics next: a descriptive alt attribute serves the screen reader, the search engine, and the multimodal model in a single gesture. Our templates block non-compliant images at upload; the safeguard is mechanical, not advisory.
