Takeaways

• 😀 Speed is crucial for the user experience, SEO, and conversion rate. A faster Shopify store enhances navigation, reduces bounce rates, and increases the likelihood of purchase.
• 😀 The first cause of slow performance in Shopify stores is large image sizes. Reducing image sizes (recommended size: 900x900) is a crucial first step in improving speed.
• 😀 Use tools like iLoveIMG to resize images without losing quality. Reducing image dimensions significantly helps improve load times.
• 😀 Compressing images is essential to reduce page weight. Use applications like SImage to automatically compress images across your store.
• 😀 WebP format is the optimal choice for image compression. It’s the most efficient format for both SEO and performance, especially for images without transparency.
• 😀 For images with transparent backgrounds, use PNG, and for icons, use SVG as they are lightweight and scalable.
• 😀 Testing and optimizing images in the correct sequence is important: resize, then compress, and finally convert to the optimal format.
• 😀 Applications can slow down your Shopify store. Carefully choose the applications you install, and test them on a partner store before applying them to your live site.
• 😀 Shopify Partner accounts allow you to test apps and make optimizations on a sandbox store before affecting your live site. Keep your main store clean and minimalistic.
• 😀 Limit the number of apps installed on your store to under 10, and avoid adding features you won’t use, as unnecessary apps increase code bloat and slow down your site.
• 😀 When testing the speed of your store, avoid testing while logged into your Shopify account, as it can skew results. Use a device that hasn’t opened the store before for accurate results.
