Page speed is no longer just a technical metric—it directly impacts SEO rankings, user experience, and conversions. Google prioritizes fast websites, and users expect pages to load in under three seconds.
If your HubSpot website feels slow, the good news is this: HubSpot CMS is built for performance. With the right optimizations, it can deliver excellent page speed scores without relying on heavy plugins or external tools.
This guide explains how to improve page speed on HubSpot CMS, what slows websites down, and how to fix it correctly.
A slow website can:
Increase bounce rates
Reduce conversions
Hurt Core Web Vitals
Lower search rankings
Google officially uses page speed and Core Web Vitals as ranking factors, making performance optimization essential.
HubSpot CMS includes several built-in performance features that many users overlook:
Global CDN for faster delivery
Automatic image compression
Built-in caching
Minified CSS and JavaScript
Secure, fast hosting infrastructure
These features give HubSpot CMS a strong performance foundation right out of the box.
Despite HubSpot’s strong infrastructure, page speed issues often occur due to:
Unoptimized images
Heavy custom CSS or JavaScript
Excessive third-party scripts
Poorly built custom modules
Unused fonts and animations
Identifying these issues is the first step toward improvement.
Always use:
Correct image dimensions
Modern formats (WebP where possible)
Lazy loading for offscreen images
HubSpot’s image optimization works best when images are uploaded correctly.
Analytics tools, chat widgets, and tracking pixels can slow down pages.
Best practices:
Remove unused scripts
Load scripts asynchronously
Limit marketing tools per page
Avoid:
Inline CSS on every module
Duplicate JavaScript files
Large animation libraries
Combine and load scripts only where needed.
Custom modules should be:
Lightweight
Reusable
Free from unnecessary code
Poorly built modules are one of the biggest performance killers on HubSpot CMS.
Limit font families and weights
Use system fonts where possible
Preload critical fonts
Fonts often cause hidden page speed issues.
Lazy loading delays images and videos until they are needed, reducing initial load time and improving Core Web Vitals.
HubSpot CMS supports optimization for:
Largest Contentful Paint (LCP)
First Input Delay (FID)
Cumulative Layout Shift (CLS)
Improving page speed directly enhances these metrics, leading to better SEO performance.
