How to Speed Up a Squarespace Website
That's the short version. Here's how to actually fix it step by step.
1. Compress and resize images before uploading
Oversized images are the single biggest cause of slow Squarespace sites. Resize images to the actual dimensions they'll display at, compress them before upload, and avoid uploading raw camera or phone files straight from your device.
2. Remove unused code blocks and third-party embeds
Old code blocks, unused tracking scripts, and embedded widgets from tools you no longer use keep loading in the background even when nobody's using them. Go through every page and remove anything that isn't actively earning its place.
3. Simplify heavy page sections
Sections with large background videos, multiple animations, or stacked galleries all add load time. Replace background video with a compressed static image where possible, and limit animations to ones that genuinely add value.
4. Check your Core Web Vitals scores regularly
Use Google's PageSpeed Insights or Search Console to check Core Web Vitals after every major page update, not just at launch. A site that scores well on day one can quietly slow down as more images, sections, and integrations get added over time.
5. Clean up fonts and animations
Loading too many custom fonts or font weights adds unnecessary load time. Stick to two font families maximum, and use built-in Squarespace animations sparingly rather than adding extra animation plugins on top.
6. Test on mobile, not just desktop
Most Squarespace traffic is mobile, and mobile connections are slower and less forgiving than desktop. Test load speed on an actual phone over standard mobile data, not just on a fast office wifi connection, since that's the experience most visitors actually have.
Frequently asked questions
Why is my Squarespace site slow even though it's a hosted platform?
Hosting handles server speed, but page weight from images, embeds, and code blocks is entirely down to how the site is built. A poorly built page on fast hosting will still load slowly.
Does site speed actually affect my Google rankings?
Yes. Core Web Vitals are a confirmed Google ranking factor, and slow-loading pages also tend to have higher bounce rates, which compounds the ranking impact further.
How often should I check my site's speed?
Check after any major content update, and otherwise once a month as routine maintenance, since speed tends to degrade gradually as more content gets added rather than breaking all at once.
