Mon site se charge lentement

If your site is loading slowly, here are some common issues you can troubleshoot.

To see if a site loading problem is a system-wide issue, check our Status page.

Use a supported browser

We support the browser versions listed in this guide for viewing and editing your site. Squarespace sites might load slowly on other versions.

Check if your browser is current, and download the latest version. For more resources, Chrome, Safari, and Firefox have built-in tools you can use to investigate loading issues.

Maintenez la taille de vos pages en dessous de 5 Mo

When a browser first loads a page, it downloads all of the page's content. This can seriously affect load times if your page has a large amount of content. For example, pages with a lot of images can load slowly, especially on mobile devices and slower connections.

Check your page content size, and then visit Increasing page loading speed for tips on speeding up page loading.

If your template supports it, enable Ajax loading, which tells browsers to load your site one page at a time.

Check your local connection

If your site is loading slowly on pages with small amounts of content and your browser is up-to-date, there could be an issue with your local network.

If you can, try viewing your site on another network. If you have good cell coverage, you can also try accessing your site from a smartphone with the Wi-Fi disabled.

You can also troubleshoot this with a speed test. If your upload and download speeds are lower than what your Internet service provider has promised, contact them to see if there might be an issue.

Remove custom code

Custom code—including third-party embed code, code injections, and CSS—may cause your site to load slowly. When troubleshooting load time issues, remove all custom code from your site, save it in a text document for safe keeping, then refresh the page.

Check URL redirects

Too many URL redirects can cause page speed issues. Check your URL redirects in the URL Mappings panel. If you have a large number of redirects, streamline the list wherever possible.

Check your mobile compatibility

If your site is loading slowly on a mobile device, use Google’s Mobile-Friendly test to see if your site is mobile friendly. If it's not, visit Tips on keeping your Squarespace site mobile-friendly, and Reduce page sizes for faster loading.

Google's PageSpeed Insights errors

Google’s PageSpeed Insights is a tool for developers who code their sites from scratch and can return false negatives for Squarespace sites which are built on a custom CMS. If you see an error while using this test, it doesn’t necessarily mean there’s an issue with your site.

To get a sense of your site’s actual site load time, use tools like Pingdom or your browser's built-in inspection tool. For example, you can use the following steps with Google Chrome:

  1. Open Developer Tools.
  2. Click the Network tab.
  3. Refresh the page to display the Load time.

Check for other causes

A variety of other factors can affect your site's load time. This includes:

  • Computer memory/capacity
  • External scripts added to the site
  • Local network firewalls
  • Anti-virus software
  • Browser add-ons
  • Issues with third-party domain providers

Try temporarily disabling any browser extensions, anti-virus software, and external scripts that may be impacting your site.
