HubSpot PageSpeed Guide: How to Use Google PageSpeed Insights

If you manage a site with Hubspot, learning how to use Google PageSpeed Insights is essential for improving performance, search visibility, and user experience.

This guide walks through what PageSpeed Insights is, how it works, and how you can apply its recommendations to any site, including those built with HubSpot or connected through tracking code.

What Is Google PageSpeed Insights for HubSpot Users?

Google PageSpeed Insights is a free tool that analyzes how quickly a page loads and how stable and responsive it feels to visitors on desktop and mobile devices.

For HubSpot users, it helps you:

• Measure how fast your HubSpot pages load.
• Understand which elements slow down your content.
• Prioritize fixes that improve Core Web Vitals.
• Support SEO efforts and conversions.

The tool combines real user field data (from the Chrome User Experience Report when available) with lab data from Lighthouse to give you practical, prioritized recommendations.

How to Run a PageSpeed Insights Test for HubSpot Pages

You can analyze any public URL, whether it is hosted on HubSpot, a CMS, or a static site.

Step 1: Open the PageSpeed Insights Tool

Visit the official PageSpeed Insights page at Google PageSpeed Insights guide. This resource explains how the tool works and what the major metrics mean.

Step 2: Enter Your HubSpot Page URL

Copy the full URL of the page you want to test from your HubSpot domain. Paste it into the input field and click the button to analyze.

You can test:

• Landing pages built in the HubSpot drag-and-drop editor.
• Blog posts hosted on your HubSpot subdomain.
• Website pages you manage through HubSpot CMS Hub.

Step 3: Review Mobile and Desktop Results

PageSpeed Insights shows results for mobile first, followed by desktop. Both matter, but mobile is especially important for SEO and user experience.

Look at:

• The performance score (0–100).
• Whether the page passes the Core Web Vitals assessment.
• Field data (if available) for real user performance.
• Detailed diagnostics from Lighthouse lab tests.

Key Metrics HubSpot Marketers Should Understand

Whether your content is on HubSpot or another system, these metrics define how Google sees your page performance.

Core Web Vitals for HubSpot Pages

• Largest Contentful Paint (LCP): How long it takes for the main content to load. Aim for 2.5 seconds or less.
• First Input Delay (FID) or Interaction to Next Paint (INP): How quickly your page responds to user input. Lower is better.
• Cumulative Layout Shift (CLS): How much your layout jumps around as elements load. Try to keep it under 0.1.

Improving these metrics on your HubSpot pages helps users see content faster, interact smoothly, and avoid frustrating visual shifts.

Other Helpful PageSpeed Metrics

• First Contentful Paint (FCP): When the first text or image is rendered.
• Total Blocking Time (TBT): How long scripts block the main thread.
• Speed Index: How quickly content visually appears during load.

These metrics give you deeper insight into where delays happen, even on simple HubSpot layouts.

Common Performance Issues on HubSpot and How to Fix Them

PageSpeed Insights groups opportunities by impact, so you know what to fix first. Many findings apply directly to HubSpot pages.

1. HubSpot Images: Optimize Size and Format

Large or unoptimized images are one of the most frequent causes of slow pages.

Use these best practices:

• Resize images to the maximum size they will display.
• Compress images before uploading (JPEG or WebP for photos, PNG or SVG for graphics).
• Use lazy loading where possible so below-the-fold images load later.

PageSpeed Insights will often highlight images that could be compressed or served in next-gen formats.

2. Reduce JavaScript Impact on HubSpot Pages

Heavy JavaScript can increase Total Blocking Time and hurt your PageSpeed score.

To improve performance:

• Remove unused scripts from templates or tags.
• Avoid stacking multiple tracking scripts that duplicate functionality.
• Defer non-critical scripts so they load after key content.

If you use external tools in addition to HubSpot, consider consolidating tags to reduce overhead.

3. Minimize CSS and Layout Shifts

Excess or render-blocking CSS can delay the first paint and contribute to layout shifts on HubSpot pages.

Helpful actions include:

• Keep global style sheets lean and organized.
• Specify width and height for images and embeds to prevent CLS.
• Avoid inserting banners above existing content after load.

PageSpeed Insights will flag cumulative layout shift problems and point to specific elements causing issues.

Using PageSpeed Insights in a HubSpot Optimization Workflow

To get lasting gains, treat PageSpeed analysis as a recurring part of your HubSpot content and development process.

1. Test Before and After Major Changes

Whenever you redesign templates, add new modules, or change themes in HubSpot, run tests on key pages before and after the changes. This confirms that performance is improving instead of degrading.

2. Prioritize High-Value HubSpot Pages

Begin with:

• Top-converting landing pages.
• High-traffic HubSpot blog posts.
• Critical product or pricing pages.

Improvements on these URLs usually deliver the largest impact on leads and revenue.

3. Track Performance Over Time

Run PageSpeed Insights periodically and keep a simple log of scores and key issues. Combine that with analytics from HubSpot and other tools to see how faster pages influence engagement and conversions.

When to Get Additional Help Beyond HubSpot Tools

Sometimes you need more than template tweaks and image compression. In those cases, working with performance and SEO specialists can accelerate results.

Next Steps for HubSpot Site Performance

Using Google PageSpeed Insights regularly gives you a clear roadmap for improving speed on any site, including those managed with HubSpot.

1. Identify your most important pages.
2. Run tests for mobile and desktop.
3. Address high-impact opportunities like images, scripts, and layout shifts.
4. Re-test and document improvements.
5. Repeat the process as you update templates and content.

By pairing PageSpeed Insights with consistent optimization in HubSpot, you can deliver faster experiences, support your SEO goals, and create a smoother journey for every visitor.
