How to fix page speed warning on Squarespace

Steps for Squarespace

1. Images: In the Squarespace editor, click any image block and in Image Settings choose the correct focal point and reduce the image file size before uploading by using Squarespace's built-in 'Compress images on upload' setting (Settings > Advanced > Image Compression). Squarespace serves images via Fastly CDN and converts to WebP automatically.
2. Video backgrounds: In the Pages panel, click any section that uses a video background and replace it with a high-quality static image — video backgrounds are the biggest single Squarespace speed issue.
3. Code injection: Go to Settings > Advanced > Code Injection and audit any custom HTML/CSS/JS you or a developer has added. Remove or defer any third-party scripts that are not business-critical.
4. Fonts: In Design > Fonts, reduce the number of font styles you use. Each distinct font weight or style is a separate HTTP request. Choose two fonts maximum and limit to the weights you actually use.
5. Extensions: Go to Extensions in your Squarespace dashboard and remove any extension (third-party app) you are not actively using.
6. Squarespace does not allow server-level caching configuration — it is handled automatically — so focus on asset optimization (images, video, scripts) and reducing page complexity.

What is page speed warning?

Page load time is how long it takes for a visitor's browser to fully display your store page after they click a link or type your URL. When a page takes more than 1.5–2 seconds to load, visitors experience a noticeable delay before they can see and interact with your content. A load time of 3 seconds or more (like the example finding) is considered slow by both Google and modern shoppers. Page speed is measured by several signals — the most important being Google's Core Web Vitals, which assess how fast your content appears, how quickly it becomes interactive, and how stable the layout is as it loads.

Google has officially made page speed and Core Web Vitals a direct ranking factor for all pages. Slow pages rank lower in search results, meaning fewer people find your store organically — costing you traffic and revenue before a visitor even arrives. For shoppers who do visit, studies consistently show that every additional second of load time reduces conversions: a 3-second page loses a significant portion of mobile shoppers to bounce before they see a single product. Slow stores also perform poorly in Google's mobile-first index, which evaluates your mobile experience first when deciding your rankings. Fixing page speed is one of the highest-ROI improvements an ecommerce store can make — it simultaneously boosts your SEO rankings, increases conversion rates, and improves accessibility for users on slower connections or lower-end devices.
