INP replaced FID, and thresholds got stricter. How we hit green on every build.
Server rendering, image optimisation, and preloading the hero asset handle most of it.
Break up long tasks, defer non-critical scripts, and avoid heavy third-party tags.
Reserve space for images, ads, and fonts. Layout stability is a design discipline.
The web stack keeps evolving — React Server Components, stricter Core Web Vitals, headless CMSs, AI-driven interfaces — but the goals are constant: fast, accessible, discoverable, maintainable. This article explains how we make those decisions on client projects and what actually moves performance and rankings in 2026.
| Core Web Vital | Threshold (good) | Most common fix |
|---|---|---|
| LCP | ≤ 2.5s | Server rendering, image optimisation, preload hero asset |
| INP | ≤ 200ms | Break up long tasks, defer third-party scripts |
| CLS | ≤ 0.1 | Reserve space for images, ads, and fonts |

Performance budgets enforced in CI, real-user monitoring, and a rule that third-party scripts need justification.
