13 Simple Steps to Speed Up a Squarespace Website
Speeding up your Squarespace site doesn’t have to be complicated. These simple, practical steps can help improve performance without needing any technical expertise.
1. Use Squarespace 7.1 Instead of 7.0
If you’re still using Squarespace 7.0, upgrading to version 7.1 can make a noticeable difference in your site’s speed and overall performance.
- Squarespace 7.1 is better optimized for performance
The newer version has been improved over time to align more closely with Google’s Core Web Vitals. In real-world use, many 7.1 sites tend to load faster and perform more consistently compared to older 7.0 templates. - 7.0 templates are no longer getting major speed updates
Squarespace is focusing its improvements on 7.1, which means older templates won’t benefit from future performance enhancements. - Cleaner structure and better rendering
Version 7.1 uses a more streamlined layout system, which helps reduce unnecessary elements on the page and improves loading behavior, especially on mobile devices. - Access to modern features
You also get newer tools like Fluid Engine and Blueprint, which not only improve design flexibility but can also help you build lighter, faster pages. - Upgrade carefully
You can upgrade from your dashboard by going to Website > Design and selecting the “Update to Version 7.1” option.
But once you fully switch, you can’t go back to 7.0. For many site owners, it’s safer to test a new 7.1 version first and compare performance before making the final move.
- Don’t forget SEO during migration
If you decide to switch, make sure your URLs, redirects, and structure remain intact. Poor migration can impact rankings if not handled properly.
2. Make Pictures Load Faster:
Images often make up 50–70% of a webpage’s total size. Squarespace has a built-in feature that speeds up how your website’s images load, which helps your site run more smoothly. It automatically reduces the size of images without affecting their quality, so they load quickly on any device and internet connection.
This feature uses the next-gen WebP image format, supported by 97% of browsers worldwide, reducing file size by 25-35% compared to JPEG without noticeable quality loss. For even better results, you can use tools like Image Optimizer Pro or Compressor.io alongside Squarespace’s built-in optimization. For best image quality, aim for a size in the range of 200 KB – 500 KB, as this is ideal for most web pages.
3. Use Lazy Loading
Lazy loading is a smart way to improve how your website works by loading pictures and videos only when they’re about to appear on someone’s screen. This means your page loads faster because it focuses first on what’s visible, adding other content as you scroll. A page with many images or long paragraphs benefits the most from it since it does not need to download all images and several paragraphs simultaneously.
Squarespace already includes lazy loading as a built-in feature, but if you want more effective results and you’re not familiar with coding, a no-code tool like Website Speedy can be your great ally. With such tools, you can increase the loading speed of your page by about 20% to 25%, ensuring smoother performance without needing any technical expertise.
4. Prioritize Asynchronous Loading for Resources
Asynchronous loading is a technique where resources like JavaScript, stylesheets, and images load individually from the other elements within your webpage. This means these scripts don’t slow down the main content, allowing your page to appear quicker for visitors. It’s a smart way to improve the user experience because key content shows up fast while less critical elements continue loading in the background.
Implementing asynchronous loading can potentially increase your site’s loading speed by 25-35%, depending on the level of optimization you apply to it.
5. Fixing Render-Blocking Issues
Render-blocking resources, like certain CSS and JavaScript files, can delay the display of your page’s main content. These files force the browser to wait until everything is fully loaded, which can slow down how quickly your site appears to users.
Fixing render blocking usually involves prioritizing critical CSS and deferring non-essential JavaScript so your content loads faster. While this can be a bit technical, especially on platforms like Squarespace, even small improvements here can noticeably enhance loading speed, user experience, and overall site performance.
6. Optimize CSS and JavaScript Files
Make Pictures Load Faster to help speed up a Squarespace website, you can compress the CSS and JavaScript files. Fortunately, Squarespace has a feature for this. It takes out spaces, comments, and line breaks, making loading your files faster. This stands as one of the built-in tools that function automatically and help optimize the website’s functionality on any device or browser.
Furthermore, for an even higher level of customization, you can use some other third-party tools as well, like UglifyJS or Minifier, to compress your code manually. That is why this process is relatively uncomplicated and results in improved loading time and expression that does not require skills or time.
7. Turn on AMP for Blog Posts
AMP is another simple optimization technique that you can apply to your Squarespace site. When enabling AMP, users can boost their speed for the content and, in some cases, reduce the loading time by half.
Use AMP for Squarespace site
You can simply use this on your Squarespace website by clicking on the ‘Use AMP’ checkbox provided under Settings > Blogging.
Be mindful of the fact that AMP only works on the blog pages, and the other pages on your site do not have this feature.
8. Use Content Delivery Network (CDN)
Squarespace provides a built-in Content Delivery Network (CDN) to easily improve your website’s loading speed. This feature automatically spreads your website’s static content, like images and style files, across many servers around the world. This way, it shortens the distance data has to travel, so users get content from the closest server, which greatly speeds up loading times.
Because this CDN feature is part of Squarespace, you don’t need extra or third-party tools, making it a simple way to boost your site’s performance.
9. Cut Down on Redirects
Redirects are important for moving users from one web address to another, but too many can slow down your site. There are two main reasons to limit redirects: content changes and URL details. When you change content, use 301 redirects to tell search engines that the old page has permanently moved, which helps keep your SEO score.
Temporary redirects (302) can be helpful during changes, but too many can cause a series of redirects, making your site load slower. This way, you improve user experience since links go directly to the right pages and make your site faster.
10. Enable Ajax Loading Option
If you are using Squarespace version 7.0 and your template allows it, enabling Ajax loading can speed up page transitions by loading only the necessary content instead of refreshing the entire page. This creates a smoother and more seamless browsing experience, making it ideal for content-heavy pages like blogs, galleries, and store pages.
However, Ajax loading may not be compatible with certain third-party scripts, embedded content, or custom code, so it’s important to test your site after enabling it to ensure everything functions correctly.
To enable Ajax loading, follow the steps:
Home > Design > Site Styles > Enable Ajax Loading

11. Make Your Website Load Faster by Reducing HTTP Requests
Browsers need to make HTTP requests to get all the parts of a webpage, like HTML, CSS, images, and scripts. The more requests they send, the longer it takes for the entire page to load.
To make your website faster, follow these suggestions:
- Keep the items on each page to a minimum to lower the total number of requests.
- Combine your CSS and JavaScript files to make loading faster and more efficient.
- Ensure your images are the correct size and format for the web.
With these techniques, you can optimize the site speed and how it runs in front of the user quickly and effectively.
12. Choose Web Fonts That Load Quickly
Using the right type of fonts for your website is important for faster loading time and a good browsing experience. Always use common fonts that are default, pre-installed, or publicly downloadable so that resources do not load extra fonts on the browsers. This helps your site load faster and improves compatibility.
You can also employ Google Fonts for simplicity. To get better control, please consider using the font-display property that ensures your content is visible as soon as possible, even if the fonts are not yet fully loaded. The use of a single static font family also results in less delay in page loading as well.
When it comes to fonts, the right choices can help you create a visually aesthetically pleasing as well as functional website.
13. Minimize Third-Party Plugins for Optimal Performance
Most of the third-party plugins are useful for any Squarespace site, but excessive use of them leads to site issues and slower speed. Every plugin inserts additional code that might be quite time-consuming for browsers and thus influences page loading time a lot.
To ensure optimal performance, focus on using only essential plugins that deliver substantial value to your users. Regularly assess the plugins you have in place and eliminate any that are not critical. By streamlining your site’s functionality, you can improve load times and provide a smoother user experience, making your website faster and more efficient.
How to Improve Core Web Vitals on Squarespace
Core Web Vitals are important Google ranking signals that measure real user experience, including loading speed, interactivity, and visual stability.
- Largest Contentful Paint (LCP): Should be under 2.5 seconds. Improve it by optimizing images and reducing server response time.
- Interaction to Next Paint (INP): Should be under 200 milliseconds. Reduce JavaScript and avoid heavy scripts.
- Cumulative Layout Shift (CLS): Should be below 0.1. Prevent layout shifts by defining image dimensions and avoiding dynamic content shifts.
While Core Web Vitals alone won’t guarantee higher rankings, improving these website performance metrics can enhance user experience and contribute positively to your SEO performance.

FAQs
Q1: Why Is My Squarespace Site Slow?
If your Squarespace site is loading slowly, several factors could be causing the issue, including large images, excessive third-party scripts, embedded videos, too many plugins, and unoptimized fonts, all of which can significantly impact load times. To improve performance, optimize images, enable lazy loading, fix render-blocking issues, and minimize heavy external integrations as soon as possible.
Q2: Will a faster website improve my SEO on search engines?
Definitely! Google and other search engines favor sites that load quickly, which makes them rank higher. Faster load times boost your site’s Core Web Vitals, making it more attractive to search engines and improving overall SEO.
Q3: Should I upgrade from Squarespace 7.0 to 7.1 for better speed?
Upgrading to Squarespace 7.1 can improve your site’s performance since it’s better optimized for modern speed standards and Core Web Vitals. However, the upgrade should be done carefully, as you can’t revert to 7.0 once it’s published. Before switching, test your new version and ensure your URLs, redirects, and SEO structure remain intact to avoid any ranking issues.
Q4: How does mobile optimization affect my website’s performance on mobile?
Mobile optimization is essential since more users browse on phones. Since a mobile-friendly site loads much faster and is much easier to navigate, which makes for a better user experience, Google will rank it higher on its mobile-first index.
Q5: What’s the difference between lazy loading and deferring scripts?
Lazy loading delays the loading of images and videos until the user scrolls to their location, which ultimately speeds up the initial load time. On the other hand, deferred scripts wait for the page to load first and then load the unimportant code so your site seems to load faster, and it leaves a better first impression on visitors.
Q6: How does a faster website impact my online sales and conversions?
A website that loads quickly makes people want to stay longer, which means they are more likely to buy something. Faster loading times create a smooth experience, which can result in more sales and satisfied customers. Google data shows that just 1 second of extra load time can lower conversions by 20% on mobile, highlighting how crucial speed is for retaining potential buyers and boosting sales.
