Few things that can speed up Page Speed of Your eCommerce Website

If your website is taking time to load, consider analyzing your website through Google Page Speed tool. This will help you understand what is taking the most time so that you can clean up the problematic HTML, CSS and Javascript code. Given below are some best practices:

The most important thing that affects the performance of your website page speed is the Web hosting. One can improve the performance of his or her eCommerce website by opting for a Dedicated or Fast Website server. Even though it may cost you more, but being on a slow server can cost you even more in sales long term.

Ineffective Search Server ensures that you don’t last long in the e-commerce business so choose wisely.

CDN is a company that has a large number of servers placed in several places to deliver web pages to visitors. If your website has large amounts of display content, prefer using a content delivery network (CDN). The main issue a CDN address is latency or the amount of time it takes to deliver web pages to the user.

  1. Use CSS Sprites:

CSS Sprites is a technology to transform multiple images into one big image. This will reduce the number of concurrent connections and your website will load faster.

  1. Use Caching System:

By caching your web pages, you can make your website faster. The request will be served directly from an earlier saved page on your web host. This reduces the server load and serves up your website’s pages instantly.

  1. Compress the Image Sizes:

Compressing images and text improve websites performance and speed up page load time. Compression reduces the data transfer load on the server. Some hosting providers by default compress websites. You can use tools like Google Page Speed that can let you know if your website needs compression. If your images need compression, you can use a tool like to compress them.


The Faster The Better!

A fast website definitely gives a WOW feeling even if gives you what you want or not, the biggest examples are Google and Amazon one just comes back for more. Even though a customer may not buy on your eCommerce portal for the first time but the super-fast experience he/she gets will make you are on their fingers when they go shopping online.

An eCommerce website that provides customer experience is more likely to sustain competitive advantages. From satisfying buyers to accomplishing higher search engine rankings, the importance of website speed must not be ignored and continually accelerated when possible.
