Introduction


Google Core Web Vitals are now a critical factor for SEO and user experience. These metrics—Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS)—measure how fast your pages load, how responsive they are, and how stable the layout is for visitors.

Optimizing HubSpot CMS pages for Core Web Vitals ensures your website is fast, smooth, and SEO-friendly, keeping users engaged and improving search rankings.

1. Optimize Largest Contentful Paint (LCP)

LCP measures how quickly the main content of a page loads. To improve LCP on HubSpot CMS:

  • Compress and optimize images (use WebP format)

  • Reduce server response times (HubSpot’s CDN helps here)

  • Minimize render-blocking CSS and JavaScript

Tip: Use HubSpot CMS’s built-in image optimization and caching to speed up LCP.

2. Reduce First Input Delay (FID)

FID measures how quickly a page responds to user interactions. Slow responses frustrate users. To reduce FID:

  • Minimize heavy JavaScript execution

  • Use HubSpot CMS optimized custom modules

  • Avoid third-party scripts that block interactivity

Pro Tip: HubSpot CMS allows asynchronous loading for scripts to improve responsiveness.

3. Fix Cumulative Layout Shift (CLS)

CLS measures unexpected layout shifts that annoy users. Common causes:

  • Images without width and height attributes

  • Ads or embeds that load dynamically

  • Fonts that cause flash of unstyled text

Fix:

  • Always set image dimensions in HubSpot modules

  • Use HubSpot CMS global styles to prevent font shifts

  • Avoid dynamic content that pushes other elements

4. Enable Browser Caching & CDN

HubSpot CMS provides global CDN hosting, which ensures:

  • Faster page delivery worldwide

  • Reduced server load

  • Cached static assets for repeat visitors

This improves all Core Web Vitals metrics while providing a consistent user experience.

5. Minimize and Optimize Scripts

Heavy scripts are a major Core Web Vitals killer. HubSpot CMS allows:

  • Minified JavaScript and CSS

  • Lazy loading of non-critical scripts

  • Optimized custom modules for speed

Reducing unnecessary scripts improves FID and LCP dramatically.

6. Use Responsive, Mobile-First Design

Mobile users are the majority of website traffic. HubSpot CMS supports:

  • Mobile-first templates

  • Responsive modules for images, videos, and forms

  • Testing across devices for stable layouts

Optimized mobile design reduces CLS and improves engagement metrics.

7. Monitor and Test Core Web Vitals

Regular monitoring is essential:

  • Use Google PageSpeed Insights or HubSpot CMS analytics

  • Identify slow-loading pages, layout shifts, or interaction delays

  • Continuously optimize based on performance data

Tip: HubSpot CMS pages can be previewed in different devices to catch CLS and LCP issues early.
