In this post, I’m going to show you how to speed up a Squarespace site. Read on to discover nine simple steps you can take to make your site load faster — and improve its performance in search results.

If you’ve been reading about SEO, you’ve probably learnt that fast-loading sites are given preference over slower ones, and are prioritized accordingly in search results.

And, if you’re a Squarespace user, you might be thinking that your options are rather limited on this front.

In many ways this is true, because Squarespace is a ‘hosted solution’ — so you get limited control over code and templates, and none over hosting.

But there are still a lot of things you can do to speed up your Squarespace site, and in this post, we give you a checklist of the key steps you can take to ensure that you have the fastest Squarespace website on the block!

Before you get stuck in with our tips though, you need to take a close look at the existing performance of your site as far as site speed goes.

Let’s take a look at how to do that.

Before starting, check your existing site loading time

To see how fast your Squarespace site is currently loading, you’ll need to run it through a speed checking tool.

There are two reasons for doing this.

First, speed checking tools give you a very precise loading time for your site — down to the millisecond, in fact — and highlight very specific areas where you can make improvements.

You may find out, for example, that a particular script you’ve added to your site is taking ages to load, or that your images are too big — and you’ll be able to tweak your Squarespace site accordingly.

Second, by using a speed checking tool before making any speed improvements to your site, you get a benchmark figure that you can refer to at the end of the process.

This lets you evaluate how successful your optimization efforts have been — and if there’s any further room for improvement.

Now, you might be tempted to use Google’s PageSpeed Insights tool for this job, but Squarespace advises users not to use it, saying:

I’m a bit skeptical of this statement, to be honest — Google uses the ‘Lighthouse’ technology behind PageSpeed Insights as part of its ranking process, and the overall score it generates is relevant to users of any platform.

This is especially the case since the introduction of Google’s Core Web Vitals targets — a set of new targets relating to the speed, responsiveness and visual stability of a website.

That said, I generally recommend using GTmetrix over PageSpeed Insights for speed tests on Squarespace sites (or at least in conjunction with it) because it gives you more ‘actionable’ information about the bottlenecks on them.

Enter your Squarespace’s site’s URL into GTmetrix and it will give you a breakdown — or ‘waterfall’ — of exactly how long each script or piece of content is taking to load (see screenshot below for an example).

You can use these insights to identify areas of improvement in addition to working through the recommendations below.

(It’s worth noting that GTMetrix will flag up some aspects of your Squarespace site that can’t really be changed — like the wait time for SSL, for example, or how long it takes Squarespace to load images hosted on its own servers. But overall, it’s very useful for identifying slow-loading content or fonts, or spotting a slow DNS lookup time…more on all that below!).

Now, let’s take a look at the exact steps you’ll need to take to speed up your Squarespace site.

1. Use Squarespace 7.1 rather than 7.0

I’ve found that in general, Squarespace 7.1 is faster than 7.0.

And, based on what Squarespace’s software engineers have been telling Squarespace designers in online forums, a lot of technical improvements are currently being made to Squarespace 7.1 to speed the platform up and make it more compliant with Google’s new Core Web Vitals standards (in fact, I’ve noticed that a lot of Squarespace 7.1 sites that we work on are now meeting them — a positive development).

Importantly, Squarespace has announced that these improvements won’t be made to the older 7.0 templates.

So, particularly if you have a small Squarespace site, and you want continue using the platform — but in a speedier way! — it definitely makes sense to switch to version 7.1 of Squarespace.

You can tell which version of Squarespace your site is currently using by going to the ‘Help’ section of the Squarespace dashboard. This information will be shown underneath the main help options provided.

One thing to note: before you move everything over to Squarespace 7.1, do a quick test to ensure that you definitely will end up with a faster site once you’ve moved all your content across from version 7.0.

To do this, just start a Squarespace 7.1 trial, replicate a few pages of your old site on it, and then run these Squarespace URLs through Pagespeed Insights and GTmetrix to see the speed difference (you will need to pay for an annual Squarespace plan to carry out this test, but a 14-day refund policy applies).

If these tests show improvements, a move to Squarespace 7.1 may well make sense for you.

(And, in the long run, with Squarespace’s planned improvements, it definitely should.)

2. Switch on SSL

Want a quick speed win?

Ensure you’re using Squarespace’s SSL option — this means that your site will be delivered through the faster HTTP/2 protocol.

Switch on the accompanying HSTS option too, as this can improve security and SEO in general too.

You can enable SSL and HSTS in really easily in Squarespace by going to Settings > Advanced > SSL.

(Note that it can take up to 72 hours for these changes to take effect).

3. Reduce your image sizes

Another simple way to reduce the loading time for your Squarespace site is to keep your image file sizes as small as possible.

You’ll need to strike a balance between file size and image quality (i.e., try to keep the file small without avoid everything becoming pixelated or grainy) — but if you can get this balance right, you’ll enjoy considerably faster loading times.

Here are some key things you can do to keep image sizes low:

4. Keep scripts to a minimum

It can be difficult to avoid using third-party scripts on Squarespace websites.

Tools like Addthis and Sumo, tracking code for online advertising, web analytics scripts and bespoke Squarespace plugins can all add really valuable functionality to your website.

But the trouble is, they can also slow your Squarespace site down considerably.

So it’s worth doing an audit of the scripts you’re currently using — and getting rid of any scripts that are not adding value. The less third-party scripts on your Squarespace site, the quicker it will load.

Now, let’s take a look at fonts.

5. Be smart with web fonts

Web fonts can make a website look really slick, but they can take a long time to load.

Now, you can speed things up by using web-safe typefaces (Arial, Times, Georgia and so on).

But if you have to use web fonts (and let’s face it, a lot of us do):

You can choose which fonts to use in Squarespace by going to the ‘Design’ section in your dashboard.

If you’re using the latest version of the platform, Squarespace 7.1, you’ll then need to click ‘Site Styles’ on the left hand side of the interface, followed the ‘Fonts’ option on the right, where you’ll be able to set the fonts globally for your site.

If you’re using Squarespace 7.0, you’ll then need to click ‘Site Styles’.

Then, go through every style element involving text — headers, body copy, blog titles and so on — to ensure that only the relevant typeface is used on the site.

6. Use the custom thumbnail option for video embeds

If you’re embedding any videos on your Squarespace site, always choose the ‘use custom thumbnail’ option.

Otherwise, Squarespace has to look up and load content from video services like Youtube or Vimeo — even if a visitor to your site doesn’t actually play a video!

This can result in quite large files having to be downloaded unnecessarily, slowing things down.

(It can also result in third-party cookies being run on your site, which not only slow things down further, but can cause headaches from a GDPR perspective. See our Squarespace GDPR guide for more information on this topic).

7. Consider using AMP on your Squarespace blog posts

Switching ‘AMP’ (Accelerated Mobile Pages) on can bring drastic speed improvements to your Squarespace blog posts.

When enabled, this displays extremely fast-loading versions of your posts on mobile devices (so long as they are accessed via a Google search result).

You can find out more about AMP here, but it essentially works by stripping out non-essential code from a web page, and using smart caching to load pages really quickly.

(The video below explains how AMP speeds up websites).

To switch AMP on in Squarespace, go to Settings > Blogging and then tick the AMP checkbox.

Note however that AMP format disables quite a few standard Squarespace blocks — including code blocks and form blocks — so this one won’t be for everyone (particularly site owners that use code blocks to embed adverts on their posts).

Accordingly, it’s worth reading the Squarespace support material on AMP very carefully before switching it on.

But especially where Squarespace 7.0 sites are concerned it can bring significant speed improvements to the table.

8. Consider using AJAX loading

If you are a Squarespace 7.0 user, you may be able to make use of Ajax loading to speed things up a bit.

Ajax loading means that your site will only load the content that’s visible (rather than ALL the content on the page). For example, if a user visits a gallery page, only the visible images will load — for example, the ones above the fold. Any other pictures will load in line with the user’s scrolling, i.e., as they come into view.

Ajax loading is supported in the following Squarespace 7.0 template families:

To enable Ajax Loading, you go to Design > Site Styles and tick the ‘Enable Ajax Loading’ box.

The only thing to watch out for here is that using Ajax loading on Squarespace can interfere with how third-party scripts function.

So, if your site is particularly reliant on third-party code that you’ve added, you may need to tread carefully here — check any scripts you’ve added are still working properly after enabling Ajax loading.

9. Reduce your DNS lookup time by using a faster provider

The final step you can take to speed up your Squarespace site is to reduce your DNS (Domain Name System) lookup time.

For a technical explanation of DNS lookup time, I’d suggest reading this excellent Cloudflare resource on DNS, but a simple explanation of it is this: it’s basically how long it takes your browser to find out where on the web your domain is located.

The DNS lookup has to be performed before anything from your site can be loaded – so you want this to take as short a time as possible.

Now, some domain name providers — including well-known companies like Godaddy — don’t provide particularly fast DNS lookup times, as this chart from DNSPerf.com makes clear.

So, if you’ve registered a domain with a sluggish DNS provider, you could consider either

All this involves a bit of configuration, but if you have the know-how (or the support of somebody who does), it’s worth investing a bit of time in this.

We recently moved some domains used for Squarespace sites over to Cloudflare, and saw some significant reductions in DNS lookup times.

For information on how to do this, you can refer to the Cloudflare section on the Squarespace support site or Cloudflare’s documentation (scroll down to the ‘miscellaneous vendors’ section and click on the Squarespace link).
