The 3 Metrics That Matter
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.
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.
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.
