Speed is a critical factor for the growth of an online business. Whether it is about the fast loading of a web page or a closed check-out system, a visitor wants everything to be quick. The faster the page load, the better your online store’s ranking on Google search engine page results. Lower the page load speed, faster the bounce rate of your visitors. Hence to upscale your online business performance, you need to speed up your Shopify store for both page load and site load. 

Here are some of the top tips by an experienced Shopify eCommerce agency to optimize Shopify website speed:

2. Do Performance Analysis

If the score is crossing the limit, you can ask your development team to take action on it and improve the site’s performance accordingly.

  • Optimize images
  • Minify CSS
