Effort to fix: Moderate (a few hours)
Why it matters
LCP measures when the main content appears. Above 2.5 s visitors perceive the page as slow, and it's a Core Web Vitals ranking signal.
How to fix it
Serve the hero image in a modern format at the right size, preload it, avoid lazy-loading it, cut render-blocking CSS/JS, and use a CDN with fast server response.
On WordPress
Exclude the hero image from lazy-loading, enable page caching and a CDN, and serve WebP/AVIF via an image optimisation plugin.
