💡 How to Increase Speed

Proven strategies to boost your Shopify store's performance and loading times

🖼️

Optimize all images using WebP format and compress them before uploading. Large images are the #1 cause of slow loading stores.

📱

Remove unused Shopify apps. Each app adds JavaScript and CSS that loads on every page, even if you don't actively use the app.

🎨

Choose a lightweight, speed-optimized theme. Premium themes like Dawn, Impulse, or Turbo are built with performance in mind.

⚡

Enable lazy loading for images and videos. This loads content only when users scroll to it, improving initial page load time.

🔤

Limit custom fonts to 2-3 maximum. Each font family requires additional HTTP requests and can significantly slow down rendering.

🎬

Host videos on YouTube or Vimeo instead of uploading directly. Embed them with lazy loading to prevent blocking page load.

📊

Minimize tracking scripts and pixels. Consolidate analytics through Google Tag Manager and load non-essential scripts after page load.

🔧

Reduce homepage sections and carousels. Each section adds code and images. Keep your homepage focused and fast-loading.

🌐

Use Shopify's built-in CDN effectively. Avoid loading resources from external servers when possible to reduce DNS lookups.

📈

Test your store speed regularly, especially after installing new apps or making theme changes. Catch performance issues early.

Frequently Asked Questions about Shopify Store Speed

Learn more about Shopify performance optimization and how our speed checker can help improve your store.

Why is Shopify store speed important?

Store speed directly impacts user experience, conversion rates, and SEO rankings. A 1-second delay can reduce conversions by 7%. Fast-loading stores keep customers engaged and improve search engine visibility.

What are Core Web Vitals?

Core Web Vitals are Google's metrics for measuring user experience: Largest Contentful Paint (LCP) for loading, First Input Delay (FID) for interactivity, and Cumulative Layout Shift (CLS) for visual stability.

How can I improve my Shopify store's speed?

Key improvements include optimizing images, choosing a fast theme, removing unused apps, enabling compression, using a CDN, minimizing redirects, and optimizing your product catalog structure.

What's a good PageSpeed score for Shopify stores?

A good PageSpeed score is 90+, but for ecommerce stores, 70+ is acceptable. Focus more on Core Web Vitals and real user experience metrics than just the overall score.

How often should I test my store's speed?

Test your store speed monthly, or whenever you make significant changes like adding new apps, updating themes, or adding large amounts of content. Regular monitoring helps catch performance issues early.

Does page speed affect SEO rankings?

Yes, page speed is a Google ranking factor. Core Web Vitals are part of Google's page experience signals. Faster sites typically rank higher and provide better user experience.
