Core Web Vitals in 2025: What The SEO Company Actually Fixes (LCP, CLS, INP)

A pragmatic plan to improve LCP, CLS and INP with sprints—no rebuild required.

Start with real‑world data

We prioritise templates with poor field data (CrUX), not just lab scores—because that’s what users feel and Google measures.

Tactics that move the needle

  • LCP: priority hints on hero, correct preloads, compressed/resized images and font strategy.
  • CLS: reserve space; avoid late‑loading banners without height; stabilise components.
  • INP: reduce long tasks; defer non‑critical JS; hydrate only what’s interactive.

Quick wins we deploy

  • Switch heavy PNGs to modern formats
  • Inline critical CSS for above‑the‑fold
  • Remove or defer unused third‑party scripts

Our sprint model

  1. Pick 3 templates with the worst field data
  2. One‑week CWV sprint; redeploy
  3. Re‑measure after 28 days; repeat on the next set
