LCP (Largest Contentful Paint) is the single most impactful Core Web Vital for affiliate sites. It measures how fast the main content element loads — usually a hero image or H1.

To hit "Good" LCP (under 2.5 seconds):

— Preload your LCP image. Add `` in the ``. This alone can cut 0.5-1.5s.
— Serve images from the same origin or a fast CDN. Cross-origin image requests add DNS lookup time.
— Eliminate render-blocking resources above the fold. CSS is fine; JavaScript is not.
— Use `fetchpriority="high"` on the LCP image element.

One thing most guides miss: if your LCP element is text (like a headline), font loading becomes the bottleneck. Preloading the font file is just as critical as preloading images.

Check your LCP element in PageSpeed Insights — it highlights exactly which element is being measured. Fix that specific element, not the page in general.
