Key Takeaway

Every second of page load delay reduces conversion rates by up to 7%. While Squarespace handles server-side caching and CDN distribution automatically, page speed is directly governed by the assets and scripts you put on your pages.

1. Audit and Compress All Image Assets

Never upload raw camera photos to Squarespace

Photos directly from modern cameras or stock sites often weigh 5MB to 15MB each. Compress them using TinyPNG or Squoosh to WebP format before uploading, targeting under 250KB per image.

Limit the use of animated GIFs—replace them with short, loop-muted HTML5 videos or lightweight CSS micro-animations.

2. Clean Up Third-Party Tracking Scripts

Eliminate render-blocking JavaScript in Code Injection

Having Meta Pixel, Google Tag Manager, Hotjar, Pinterest Tag, and multiple live chat widgets simultaneously will cripple your mobile Core Web Vitals score.

Consolidate your tracking pixels through Google Tag Manager, defer non-critical scripts, and disable unused analytics tags.

Conclusion & Next Steps

By enforcing asset hygiene and minimizing external script dependencies, your Squarespace site will achieve green Core Web Vitals scores and deliver an instant, frictionless browsing experience.
