7 HubSpot CMS Design Mistakes That Are Killing Your Conversions (And How to Fix Them)

Introduction


A beautifully designed website is useless if it fails to convert visitors into leads or customers. Even HubSpot CMS websites—while feature-rich and flexible—can fall victim to design mistakes that silently erode conversions.

In this blog, we’ll uncover the top HubSpot CMS design mistakes that hurt conversions and show you how to fix them effectively.

1. Slow Page Load Times

Speed is critical. Even a 2-second delay can lead to higher bounce rates. Common mistakes include:

  • Overloaded images or videos

  • Too many custom scripts

  • Heavy modules without optimization

Fix: Use HubSpot CMS’s CDN hosting, lazy loading, and image compression features to ensure lightning-fast load times.

2. Poor Mobile Responsiveness

Many websites look great on desktop but fail on mobile. Mistakes include:

  • Buttons too small for touch

  • Text or images overflowing screens

  • Forms that are hard to fill on mobile

Fix: Leverage HubSpot CMS’s mobile-first design tools and test across devices for a seamless mobile experience.

3. Cluttered Layouts & Confusing Navigation

Overcrowded pages or unclear menus can frustrate visitors. Mistakes include:

  • Too many CTAs competing for attention

  • Poorly structured menus

  • Excessive information without hierarchy

Fix: Simplify navigation, prioritize visual hierarchy, and guide users toward key actions using HubSpot CMS’s drag-and-drop modules.

4. Weak or Hidden Calls-to-Action (CTAs)

CTAs are conversion drivers. Mistakes include:

  • Buttons that blend with the background

  • Vague text like “Submit” instead of action-oriented phrases

  • Placing CTAs below the fold

Fix: Make CTAs prominent, compelling, and visible. Use HubSpot CMS’s smart CTAs for personalization based on visitor behavior.

5. Ignoring SEO & Accessibility

Visitors may never find your site if SEO and accessibility are neglected. Mistakes include:

  • Missing meta tags, headers, or alt text

  • Poor contrast or unreadable fonts

  • Ignoring ARIA labels or keyboard navigation

Fix: Use HubSpot CMS built-in SEO tools, maintain accessibility standards, and structure content for search engines and users alike.

6. Overusing Stock Images or Generic Templates

While HubSpot templates are great, overreliance on them can make your site look generic. Mistakes include:

  • Repeated stock imagery

  • Non-branded modules or layouts

Fix: Customize templates with your brand elements, images, and custom modules to stand out and build trust.

7. Neglecting Analytics & Testing

Design mistakes often go unnoticed without data. Common issues:

  • No A/B testing for landing pages

  • Ignoring heatmaps or click tracking

  • Not iterating based on performance data

Fix: Use HubSpot CMS analytics, A/B testing, and heatmaps to continually optimize pages for higher conversions.
