Ranked: Interaction-to-Next-Paint Scores for Major CMS Platforms

Website performance continues to be a decisive factor in digital marketing success, and Google’s Core Web Vitals place increasing weight on responsiveness. Among these metrics, Interaction-to-Next-Paint (INP) measures how quickly a site reacts to user interactions.

For brands using Content Management Systems (CMS), INP performance directly affects both user experience and search rankings. New data highlights how major CMS platforms perform when ranked by their INP scores.

Why INP Scores Matter for CMS Platforms

Interaction-to-Next-Paint reflects the speed at which a website visually responds after a user clicks, taps, or triggers an action. A low INP score indicates fast responsiveness, while a high score suggests delays. For CMS-powered websites, INP is particularly important because:

• User Experience: Faster response times improve engagement and reduce bounce rates.
• Search Rankings: Google rewards sites with strong INP performance.
• Conversions: Delays in interactions often lead to abandoned sessions and lost revenue.

Businesses evaluating CMS solutions must consider INP alongside features, scalability, and cost.

Ranked: Interaction-to-Next-Paint Scores for Major CMS Platforms

Recent performance studies provide a clearer picture of how popular CMS platforms compare. While results vary by implementation, overall averages reveal notable differences.

High-Performing CMS Platforms

These systems consistently deliver strong INP scores due to lightweight frameworks and optimized architecture:

• Webflow – Known for producing lean code with minimal delays in rendering.
• Squarespace – Templates are designed for responsiveness across devices.
• Wix – Recent infrastructure upgrades have improved INP scores significantly.

Mid-Tier CMS Platforms

With optimization, these platforms can achieve competitive INP scores, though performance depends heavily on implementation:

• WordPress – Highly flexible but often slowed by plugin-heavy builds; careful theme and plugin selection is critical.
• Drupal – Stable and scalable but requires technical expertise for INP optimization.
• Joomla – Moderate responsiveness; benefits from caching and performance tuning.

Lower-Performing CMS Platforms

These platforms tend to lag in INP rankings due to complexity and heavier system requirements:

• Magento (Adobe Commerce) – Powerful for e-commerce but slowed by resource-intensive features.
• Typo3 – Advanced capabilities but less streamlined for performance, resulting in slower responsiveness.

How Businesses Can Improve INP Scores

Regardless of platform, businesses can take steps to improve responsiveness. Strategies include:

• Minimizing render-blocking scripts.
• Reducing plugin and extension bloat.
• Leveraging Content Delivery Networks (CDNs).
• Optimizing images, fonts, and other assets.
• Implementing server-side caching for faster load times.

These optimizations not only improve INP scores but also enhance overall Core Web Vitals performance.

The Role of Hosting in INP Performance

CMS responsiveness is heavily influenced by hosting infrastructure. Managed hosting solutions and cloud-based platforms offer lower latency and more reliable performance. Conversely, low-cost shared hosting can significantly hinder INP scores, regardless of CMS choice.

Why Marketers Should Care About INP Rankings

For marketers, INP is not just a technical metric—it directly affects campaign performance and ROI. A CMS that delivers faster interaction improves user journeys, boosts conversion rates, and strengthens brand perception.

Choosing a CMS with strong INP performance reduces the need for costly fixes later and ensures better alignment with Google’s ranking signals.
