Page Speed Testing

5 min readUpdated 1 March 2026
While Limecube themes are designed for fast loading, adding more images, video, and content can impact load speeds and scores. Limecube continuously improves Google Page Speed Insights scores with platform releases to align with Google's evolving standards.

What You Can Change Yourself

Images

Images are a common culprit for slow page speeds, especially on image-heavy pages. Limecube automatically optimises images in elements except content elements, based on upload size.

Image Size Recommendations

  1. 1Banner images — avoid uploading images larger than 150-200 KB
  2. 2Content images — keep these under 100 KB
  3. 3Use a tool like Compressnow to reduce file size while maintaining quality

Video

YouTube and Vimeo scripts can reduce your site's speed scores even though the visual loading may appear fast. Consider whether all embedded videos are necessary.

Third-Party Scripts

User-added tracking scripts (analytics, chat widgets, etc.) often cause speed problems across all platforms. Review and remove any scripts you no longer need.

What Limecube Controls

Limecube manages platform-level improvements including server infrastructure and loading location, website functionality scripts, theme code, and continuous metric alignment improvements.
