The fast loading speed of a website is synonymous to more conversions. According to a recent study, if your website takes more than 3.21 seconds to load, the visitors will step back from it. This, in turn, will increase your bounce rate and decrease your conversion rates.

The pages need to work as fast as lightning to boost conversion. High bounce rate affects the SEO rankings of the eCommerce site negatively. The best remedy to this is to optimize the loading speed of your website.

By the load speed, we mean both the page speed as well as the site speed of your website. Site speed determines the performance of the overall eCommerce site.

Whereas, the Page speed deals with the performance of a particular page. Both of them equally impact the overall speed of the site.

Reasons Behind Slow Speed Of eCommerce Sites

The eCommerce sites may load slowly because of several reasons. A few common reasons are listed below:

  • Non-minified JavaScript and CSS files
  • The webpages send out too many requests
  • Thumbnail images are not properly optimized
  • Too much dependence on external resources
  • Too many hero slides

So, now you know what is causing your website to slow down. It is time we check out the ways in which you can optimize your Shopify website speed for more conversions.

Ways To Optimize Website Speed

Below mentioned are some of the ways in which you can optimize the website speed.

Compress Images

Each eCommerce site has several images on display. All the images need to be of premium quality and accurate. The customers depend on the pictures to buy the products.

So, they rightfully demand high-resolution and accurate images. However, high-resolution pictures slow down the website. So, it is a good idea to optimize the images before uploading them.

Compressed images fasten up the speed of the website. Google offers multiple tools for optimizing images.

Almost all the eCommerce sites support images in the following formats:

  • JPEG
  • PNG
  • GIF

JPEG images have a smaller file size than PNG images. You may scale the size of your images to reduce the file size. It will help you reduce the page load time.

Many tools and third-party merchants compress and resize images automatically. Several apps may be integrated with online stores for automatically compressing the photos and PDFs.

A GIF provides an attractive user experience. It may convey the brand image of a brand perfectly. However, GIF assets are large. Even a single GIF on a page may dramatically increase the size of it.

The bigger or heavier a page is, the longer it takes to load. So, it is better to replace them with static images wherever possible.

Download A Responsive And Fast Theme

Theme can make or break your website. Theme stores have a variety of free and premium themes. A few themes can slow down your entire site. Beware of them.

To enhance conversions, it becomes important to download a responsive theme. Such themes will help optimize the website speed to a great extent.

Make sure to check the live preview of the theme before applying it. Also, the theme needs to be updated regularly to remove bugs, if any.

Mobile-responsive themes help in scaling the ranking of the website.

Since a significant percentage of people browse through the eCommerce sites through their mobiles, such themes will work wonders for them.

Replace sliders with hero layout images

Hero Image of our website

Many people love adding sliders to their pages. Also, they add several premium quality images to the sliders. As a result, the pages take a much longer time to load.

However, studies reveal that sliders need to be avoided completely. Hero images are much better when it comes to page loading speed.

A hero image is a huge web banner image. It is the first object that someone sees upon entering the site. A hero image layout also contains a summary of the page.

It helps the pages load much faster than sliders. The hero image must have the following points:

  • Powerful call-to-action buttons- Several visitors feel lost after they visit a website. To guide them, a hero image must contain several images, texts or buttons that tell the visitors what to do. “Read more” and “Shop Now” are a few classic examples of call-to-action.
  • Concise Copy-The words used to convey any message are known as copy. The information needs to be conveyed within a short time. So, the copy needs to be precise and to-the-point. The longer a copy is, the longer it takes for a page to load.
  • Attractive Image- Multiple images take a longer time to load. So, it is better to have few but attractive and meaningful images. It is human nature to love flashy and bright images.

The images may even have text and images, at prominent areas of a slide. Generally, hero images are present in the front and centre of the eCommerce site.

Several eCommerce sites and themes have rotating hero images. It rotates multiple images every few seconds. It is better to use as few rotating images as possible. Several resources provide royalty-free images.

It is important to keep the following points in mind while using rotating hero images-

  • The number of slides needs to be minimized.
  • The same style needs to be used consistently across all hero images.
  • The content needs to be as simple as possible.
  • The viewers should find the site navigable.
  • The images need to be kept in as small a file as possible. The bigger a file is, the longer it will take for the file to load.

Improve server-response time

The perfect Server-Response time is less than 200ms. Several web apps are available to monitor the server-response time. These apps make the pages work faster. The faster a site is, the higher its SEO ranking will be. Also, faster speed helps in higher conversion rate. If the server-response time is smaller, it reduces the bounce rate.

Carry out Regular Performance Analysis

Speedcurve Performance Analytics

It is a good idea to analyze the performance of any eCommerce site regularly. If the analysis reveals any flaw, fix it immediately. To optimize the performance of the website, execute the following points:

  • Minify Javascript
  • Minify CSS
  • Optimize images
  • Reduce landing page redirects
  • Avoid render-blocking Javascript and CSS
  • Compress GZIP

Let us discuss a few of the points in detail-

You need to eliminate the unnecessary spaces, punctuation marks and characters drastically so that the pages load faster.

Minification is a process which helps you remove the ill-coded HTML, Javascript and CSS from the web page. Otherwise, the pages may slow down the performance of the page.

A few Javascript or CSS codes may slow down the page. They are known as render-blocking because they load JS or CSS pages before the rest of the HTML on the web page.

You need to eliminate them, to make the script work faster. Several tools are available online to redirect the mobile-friendliness of a page.

Decrease the number of apps

Most of the apps that you download, include some JavaScript or CSS files. Even if the apps are not being used, they are running in the background. So, they slow down the speed of the site.

It is better to periodically check which apps are necessary and then delete the redundant ones.

Inactive apps occupy a lot of space and add weight to it.

Decrease the HTTP requests

Several tools are available to check the total number of requests your page makes. The following tools may reduce the HTTP requests-

  • Combine and inline all the Javascripts
  • Use the minimum number of design and functional images
  • Use a limited number of social buttons
  • Inline smaller Javascripts
  • Combine and inline the CSS scripts
  • Convert images to Base64 script

Implement lazy loading function

Developers find it easier to implement lazy loading. This function lets the visitors load images as they scroll through the images. If all the images of a room load at the same time, the upfront load time takes longer than usual.

The lazy loading feature displays the low-quality images at first. It doesn’t load anything until the user scrolls down further.

Use minimum Pop-ups

Pop-ups display a product from the product listing page. They spare you the hassle of visiting a product detail page. A product that has thirty or forty thumbnails utilize a tremendous amount of data.

As a result, they take a long time to load. It is better to remove quick view or pop-ups if it is not helping generating sales.

Minimize Broken Links and Redirects

All the eCommerce pages have links that redirect customers to relevant pages. These links help customers to get in-depth information about the products. However, a broken link redirects the customers to pages reflecting 404 errors.

Such links increase unnecessary HTTP requests. As a result, the broken links are responsible for slowing down the speed.

Too many redirects also slow down the overall speed of the site. So, it is better to avoid too many broken links.

Reasons To Optimise The Speed Of eCommerce sites

The eCommerce pages need to load faster than usual. The reasons behind optimizing the speed of eCommerce sites are as follows-

Increase Conversion Rate-

A page that loads faster reduces the bounce rate. As a result, the conversion rate soars up. There are higher chances of sales.

Increases Traffic-

A page that loads faster witnesses higher traffic. The reputation of such sites spreads through word of mouth. As a result, more people browse through such sites.

Increase visibility-

The websites that load faster have a higher SEO ranking. The moment a site loads faster, its bounce rate goes down. It starts reflecting higher in the search engines.


Such methods have proven to be effective in increasing the speed of the website. Any business needs to adapt itself according to time. Apart from implementing such tactics, it becomes necessary to use reliable and fast hosting.

A fast and reliable hosting may take the performance of the site to the next level.

Such hosting has the potential to double the speed of the website. It may also affect the average order value. The website owners may use any of the tools available in the market to check the speed of their site.  

The moment the causes are eliminated, the speed will increase. It is a good idea to check the speed of any website from time to time.  

Optimized speed is not a luxury but a necessity.
