Regularly review your website for redirect chains and aim to reduce their usage by using direct links whenever possible.
Implement 301 Redirects for Permanently Moved Pages
If you have permanently moved a page to a new URL, implement a 301 redirect. A 301 redirect informs search engines and browsers that the page has permanently moved to a new location. This ensures that users are automatically redirected to the new URL, minimizing the impact on loading speed and preserving SEO value.
Use 302 Redirects for Temporary Redirects
If you need to temporarily redirect a page, use a 302 redirect. A 302 redirect indicates that the move is temporary and that the original URL should be requested again in the future. Avoid using 301 redirects for temporary situations, as they can have long-lasting effects on search engine rankings.
Implement Asynchronous Loading for JavaScript
By default, JavaScript files are loaded synchronously, meaning that the browser must wait for each script to download and execute before continuing to load the rest of the page. Implementing asynchronous loading for JavaScript can improve loading speed by allowing other elements of the page to load while the JavaScript file is being fetched.
Add the ‘async’ Attribute to Script Tags
To load JavaScript files asynchronously, add the ‘async’ attribute to the script tags in your HTML. This tells the browser to continue parsing and rendering the page while the script is being fetched. However, be cautious when using asynchronous loading, as it may affect the order in which scripts are executed and can lead to dependencies not being resolved correctly.
Use the ‘defer’ Attribute for Scripts That Do Not Affect Page Rendering
If a script does not need to be executed immediately and does not affect the rendering of the page, use the ‘defer’ attribute instead of ‘async’. The ‘defer’ attribute ensures that the script is executed after the HTML has been parsed, allowing for faster initial page loading.
Optimize Your Website’s CSS Delivery
Optimizing the delivery of CSS files is crucial for improving loading speed and ensuring a smooth user experience. By prioritizing critical CSS and deferring non-critical CSS, you can enhance your ecommerce site’s loading speed.

By inlining critical CSS, you eliminate the need for an additional HTTP request and allow the browser to start rendering the page faster. However, be mindful of the file size and use this technique selectively for critical elements.
Load Non-Critical CSS Asynchronously
Non-critical CSS can be loaded asynchronously to prevent it from blocking the rendering of above-the-fold content. By loading non-critical CSS asynchronously, you ensure that users can see and interact with the visible content while the remaining CSS files are being fetched and applied.
Defer the Loading of Non-Critical CSS
Another approach to optimizing CSS delivery is to defer the loading of non-critical CSS. By deferring the loading of non-critical CSS, you prioritize the loading of critical resources and ensure that the visible content is displayed quickly. Non-critical CSS can be loaded after the page has finished rendering or on user interaction.
