Unoptimised Images

Oversized or unencoded images slowing your pages and burning LCP.

What it is

Serving full-resolution JPEGs/PNGs without compression, modern formats, or responsive sizing is the single biggest cause of slow pages and poor LCP.

Why it matters

Heavy images dominate page weight, wreck LCP and INP on mobile, and waste bandwidth — directly hurting rankings and conversions.

How to fix it

Convert to WebP/AVIF, compress lossy, set width/height attributes, lazy-load below-the-fold images, and serve responsive srcset sizes. Use a CDN or image optimizer.
