10 Ways to Improve Your eCommerce Website Performance

10 Ways to Improve Your Ecommerce Website Performance

When making online purchases, speed is essential. Consumers have short attention spans, so even a small delay could cause them to visit your competitors. 40% of users leave a page that takes more than 3 seconds to load.

For this reason, optimizing the performance of your eCommerce website is essential to raising conversion rates and keeping users around. 

Google, the world’s largest search engine, ranks sites in its search results based on strong Core Web Vitals.

Here are ten tried-and-true methods for increasing the page speed of your online store or ecommerce website to maximize conversions. 

Importance of eCommerce Website Performance

  • Impatient Shoppers, Lost Sales: According to studies, a 1-second delay in page load can reduce conversion rates by 7%. Every instant counts! For a quick first impression, optimize picture size (WebP!), reduce code size, and enable browser caching.
  • SEO Superpower: Google prioritizes fast-loading web pages in its search results. Use a material Delivery Network (CDN) to offer material internationally while reducing server load for lightning-quick delivery.
  • Mobile Matters: Mobile devices account for more than half of all internet purchases. Use a Content Delivery Network (CDN) to distribute content based on the user’s location, reducing latency and assuring a seamless experience even over slower connections. Imagine having mini-stores all over the world that could serve clients instantaneously!

Impact on User Experience and Business Success

Have you ever walked out of a slow-moving store? This is also true online! A slow e-commerce site (think 5+ second load times) ruins the user experience (UX).

Why? Slowness signals a bad user experience (UX). Users become impatient, puzzled (is it frozen?), and ultimately bounce. Search engines penalize slowness as well by burying your website in the results. 

Business Impact: Imagine losing 7 out of 100 prospective clients because your website is delayed. Ouch! In contrast, a speedy website generates happy, engaged consumers who convert more.

Fixes include optimizing images (TinyPNG!), minifying code (smaller files download faster!) and utilizing browser cache (pre-loading material for recurring visits). 

Speed is the silent salesperson in e-commerce. Invest in performance to improve customer satisfaction, SEO, and business growth!

10 Ways to Improve the Performance of Your eCommerce Website.

Tip 1: Optimize Images 

According to a Walmart case study, every 1-second improvement in page load speed resulted in a 2% boost in conversions. 

Images make up between 50% and 75% of your web pages’ total weight. Each image you use on a webpage generates a new HTTP request. Trimming images improves page speed and allows you to express more with less.

Lossless compression techniques such as TinyJPG or TinyPNG allow you to reduce image size without sacrificing quality.

The alt text is a description of the image that will appear in its place if it fails to load. Web administrators should use descriptive and succinct text to convey a clear picture of the image.

Product picture file names influence how well products and websites rank in search engines. Using relevant keywords in image filenames helps search engines better understand the image and its associated information.

Tip 2: Implement Browser Caching

To improve the efficiency of your online store, you should use browser caching, which allows browsers to keep the most recent web pages on the server for easy access whenever visitors request them. 

Cacheable Resources

  • Select resources to cache: Concentrate on static material such as photos, CSS, JavaScript, and typography. Because they change so rarely, these are great for caching.
  • Use caching control headers: Expires and Cache-Control headers can be used to specify cache expiration times. This specifies how long browsers save the material before obtaining it again.
  • Versioning: To invalidate cached content as it changes, use versioning in filenames. This ensures users always have access to the most recent version of the resource. 

This allows visitors to quickly view the store’s page.

Tip 3: Compress CSS and JavaScript Files

The slow speed of your eCommerce store can be attributed to large HTML, CSS, and JavaScript files.

Every byte matters. Large files take longer to download, upsetting consumers and lowering conversion rates (studies show that a 1-second wait reduces them by 7%). Minification removes superfluous parts.

  • Code cleanup: Comments, unnecessary spaces, and formatting are removed, considerably reducing file size.
  • Character Crunch: Short variable and function names are used instead of larger ones, saving bytes even further.
  • Unused Code Removal: Dead-weight code that provides no use is removed, making the file smaller.

So, there are numerous free and paid minification programs available, such as MinifyCode and UglifyJS.

Tip 4: Utilize Content Delivery Networks (CDNs)

This is especially important for online companies with a global customer base. A content delivery network (CDN) stores content on multiple servers in various locations. 

So, when a user requests a page, a nearby server answers the request rather than the master server, saving time.

For example, a consumer in Hong Kong could load a page from a server in China rather than visiting the master server in the U.S.

What about during peak shopping seasons, such as Black Friday and Cyber Monday? 

High traffic volumes can strain e-commerce platforms, causing delayed load times or site crashes. However, using a CDN mitigates these possible difficulties. CDNs can handle the increased traffic, ensuring that your website is always available and performing properly, even during peak hours.

Tip 5: Optimize Server Response Time

According to Google, visitors will quit a website if it takes more than three seconds to load, and we have previously said that server response time is extremely important in establishing how ideal your page load speed is.

As a result, a long response time will lead to a high bounce rate.

So, lowering server response time is critical for three primary reasons:

  • A better experience for your guests.
  • Reduced bounce rate.
  • Improve SEO performance. 

How To Reduce Server Response Time

  1. Ensure that you are using a reliable hosting service.
  2. Invest in a solid bot management solution – Using a bot management system, such as DataDome, can help manage bot traffic and minimize server response times.
  3. Reducing bloat and resource sizes. If your site is built on WordPress, make sure to select an appropriate theme. WordPress themes can contain numerous JavaScript and PHP codes, and when these codes are not optimized, they can significantly increase your server’s response time.
  4. Pre-fetching. Pre-fetching is the process of anticipating and executing instructions before the user requests them. For example, by anticipating the user’s future requests, some content or links can be loaded ahead of time.

Tip 6: Leverage Browser Caching

Consider regular customers flying through your store, content is already loaded! Browser caching saves images, scripts, and fonts locally to avoid downloading them on subsequent visits. This implies:

  • There will be no more waiting! Users see your store right away, which increases engagement and transactions.
  • Speedy browsing keeps people happy, lowering bounce rates.
  • Caching frees up space on your server for dynamic content, boosting overall performance and cost-efficiency. 

Tip 7: Minimize HTTP Requests

A high number of HTTP requests might also result in poor page speed. Many aspects and services have been added to online retailers to engage users and influence their purchasing decisions. All of these features increase the number of HTTP requests from the server, resulting in a slower speed.

To improve the page speed of your store, limit the number of HTTP requests by deleting all unneeded items and functionality, as well as extensions/plugins.

Tip 8: Mobile Optimization

Did you know that eCommerce mobile sales are expected to total $2.91 trillion in 2020?

According to the most recent report, nearly seven out of ten internet users would check customer evaluations on their mobile phones while in-store before making a purchase.

As a result, many eCommerce enterprises are making their websites mobile-friendly. If your website is not mobile responsive, users will not visit it and recommend it to their friends. They’ll undoubtedly start exploring alternative websites with mobile-friendly designs. You can use the Google Search Console to see if your site is mobile-friendly.  

Tip 9: Regular Performance Monitoring

Slow and underperforming websites can drive away visitors. To guarantee that your website is working optimally, you should continuously monitor and measure its many components. Tools such as Google PageSpeed and Lighthouse can assist you in conducting a website assessment and generating detailed results with recommendations for changes.

  • Lighthouse is a free and open-source program that generates a detailed report on areas for improvement. You will also find concrete strategies for optimizing certain areas.
  • Google PageSpeed is a comprehensive tool for doing website audits. It will give your website a rating out of 100 and make recommendations on how to improve its performance.  

Tip 10: Consider Content Prioritization

Uncompressed information on your website can potentially cause your users to encounter long page load speeds. To help address this issue, Google recommends:

  • Focus on what is important: Prioritize product photos, descriptions, and essential features, as these have a direct impact on sales.
  • Lazy load the rest: Non-essential aspects like reviews, social networking widgets, and animations should be left until they are necessary.
  • Content delivery networks (CDNs) prioritize content for worldwide visitors, even if it is delivered across regions.


It’s time to put your knowledge of how to increase the performance of your website into action. Create an eCommerce website for your target audience, but make it better than your competitors.

Page speed and load times are the most important aspects of website performance. After all, you want your visitors to be able to navigate your content with ease.
