Why it matters
Page speed isn't just UX, it's a ranking signal. Pages that miss Core Web Vitals thresholds drop in Google rankings, and AI agents don't see content they can't render in time.
How AIDE tests it
AIDE's scanner inspects your HTML, response headers, and where applicable external signals to evaluate wpo-explicit-width-height, then returns PASS / WARNING / FAIL / SKIPPED against the threshold. Weight: 4.5 points, severity: low.
How to fix it
- Serve images as WebP/AVIF with lazy-loading.
- Minify and tree-shake JS/CSS; defer render-blocking scripts.
- Distribute static assets via CDN; use font-display: swap.
