Boost Your Core Web Vitals: Master LCP, CLS, INP

Google's Page Experience update is coming soon, so now's the time to start improving your site's Core Web Vitals. Here's how.

Largest Contentful Paint (LCP): How long it takes for the largest content element to appear.
Cumulative Layout Shift (CLS): How often elements move around.
First Input Delay (FID): How long to respond to user input.

LCP: Make your page's hero image load first

The Largest Contentful Paint (LCP) metric measures how long it takes for the largest piece of content to appear. This is often the hero image, but it could be a video, text, or other element. LCP affects user perception of your page's speed, so prioritize it.

1. Use WebP images: WebP is a modern format that's 34% smaller than JPEG, lossy, and supports transparency.
2. Defer offscreen images: Use lazy loading and `loading="lazy"` to postpone loading.
3. Optimize images: Use `srcset` for different screen sizes, and `sizes` to serve the right size.
4. Use `srcset` for responsive images: Use `srcset` and `sizes` for multiple sizes.
5. Use `<picture>` for different devices: Use `<source>` to serve the right image.
6. Use `loading="eager"` for critical images: Load them first.
7. Use `width` and `height`: Avoid extra HTTP requests.
8. Use `intersectionObserver()`: Load images when in view.

CLS: Reduce shifts of visible content

The Cumulative Layout Shift (CLS) metric measures how much content moves around. This affects user experience, so reduce it.

1. Reserve space: Use `position: sticky` for sticky headers, footers, and menus.
2. Avoid pop-ups and interstitials: Use `position: fixed` instead.
3. Use `font-display: swap`: Load fonts asynchronously.
4. Use `display: flex`: Avoid layout shifts from fonts.
5. Use `position: absolute`: Keep ads and modals in place.
6. Use `vw` and `vh`: Avoid shifting content.
7. Use `transform: translateZ(0)`: Keep elements from popping.
8. Use `transform: translateZ(0)`: Avoid layout shifts from ads.

FID: Respond quickly to user input

The First Input Delay (FID) measures how fast your page responds. This affects interactivity, so improve it.

1. Minimize JavaScript: Limit long tasks, use `requestIdleCallback()`.
2. Use `touchstart`: Respond to touch screens quickly.
3. Use `requestAnimationFrame()`: Animate smoothly.
4. Use `async` and `defer`: Load scripts asynchronously.
5. Use `setTimeout()`: Avoid blocking the main thread.
6. Use `setImmediate()`: Schedule tasks.
7. Use `Promise.race()`: Combine tasks.
8. Use `requestAnimationFrame()`: Animate without blocking.

LCP, CLS, FID: Test your pages with Google's PageSpeed Insights.

1. Enable PageSpeed Insights: Get suggestions and scores.
2. Use Lighthouse: Audit your pages and fix issues.
3. Use Chrome DevTools: Debug and analyze.
4. Use Web Vitals: Analyze real-world data.
5. Use Chrome DevTools: Profile your pages.
6. Use Chrome DevTools: Debug your pages.
7. Use Lighthouse: Audit your pages.

LCP, CLS, FID: Use Google's tools: Improve your pages.

Conclusion: Core Web Vitals matter for your search rankings.
