Landing Page Speed: Convert the Fold to WebP

A landing page has one job and usually one huge image. Convert the fold to WebP before A/B testing headlines. You cannot split-test your way out of a 2 MB hero on mobile 4G.

Speed is a conversion feature

If the hero arrives late, the headline is invisible. Convert heroes at 1600–1920 / 75–80%, proof logos at 400 / 90%, and lazy-load below-the-fold case studies.

Why it matters

  • Ad traffic is impatient.
  • Builders (Unbounce, Instapage, HubSpot) encourage big PNGs.
  • You pay per click; you should not pay again in bounce.

How to do it

  1. Screenshot the fold and list every raster.
  2. Convert that set first. Then the rest of the page.
  3. Re-test LCP on mobile before you launch the ad.
