How to Fix Core Web Vitals in Under 5 Minutes

The 3 Metrics That Matter

LCP< 2.5s

Largest Contentful Paint

How fast the main content loads. Top offenders: render-blocking CSS/JS, unoptimized hero images, slow server response.

Fix: Preload the hero, compress images, defer third-party scripts.

CLS< 0.1

Cumulative Layout Shift

How much the layout jumps. Top offenders: images and ads without reserved space, late-loading web fonts.

Fix: Add width/height to media, use font-display: swap, reserve ad slots.

INP< 200ms

Interaction to Next Paint

How quickly the page responds to taps and clicks. Top offenders: heavy JavaScript on the main thread.

Fix: Break up long tasks, remove unused JS, batch handlers.

Frequently Asked Questions

Do I need to fix all three metrics?▾

Google assesses all three; a page should pass LCP, CLS, and INP to be considered good. Start with the metric your audit flags as worst — it usually has the biggest impact on rankings.

Can I improve Core Web Vitals without a plugin?▾

Yes. Many fixes are simple: compress images, use next-gen formats, defer non-critical JavaScript, and set explicit dimensions on media. Scanly tells you exactly which file each fix applies to.

Is speed a ranking factor?▾

Yes. Core Web Vitals have been a confirmed ranking consideration since June 2021, and the metrics remain a core part of Google's Page Experience assessment in 2026.

What about accessibility and security?▾

The same free audit covers them. WCAG accessibility issues and missing security headers are prioritized alongside speed — so you fix all three problem areas in one pass.

What is the quickest single fix that helps most sites?▾

Compressing and properly sizing hero images, and deferring third-party scripts, resolve LCP and CLS for a large share of sites — both are steps Scanly surfaces in its top recommendations.
