Get More Sales and Conversions with Better WooCommerce Performance: Do’s and Don’ts

Website speed is one of the most important aspects of a website. A slow WooCommerce store can have detrimental effects on your user experience and SEO efforts. Poor user experience can easily lead to a high bounce rate and lost sales. Lower search engine rankings mean your organic traffic is going to be low. Organic traffic is one of the best and cheapest sources of high-quality traffic. When people search for an item in search engines, they already have a buying intent. You need to be able to direct them to your store and convert them to paying customers.

WooCommerce performance needs to be constantly monitored. It is not a one-off optimization affair. Most stores tend to keep updating inventory by adding new items and removing older ones. With the constant need for updates, comes the constant need for performance monitoring. In this article, we will guide you on do’s and don’ts for WooCommerce performance.

Why WooCommerce Speed is Important?

A recent survey of more than 2,500 online consumers found that site slowness is the top reason why they’d abandon a purchase. An improvement in page speed can yield significant results in terms of conversions and sales for E-commerce stores.

In terms of search engine rankings, site speed is considered an important factor for websites to rank high on search engines and to get more traffic to your online store.

Also, in terms of user experience, site speed is one important factor to consider when designing a better user experience for your customers as that will definitely yield better results for your online store.

So search engine rankings, user experience, and conversions will all get improved when you have a better WooCommerce performance that attracts and retains visitors in your online store.

What are the Elements that Impact Website Speed for an E-commerce Store?

Several elements can influence the loading speed of an e-commerce store:

Web Hosting: The quality and location of the server hosting the website can have a significant impact on speed. Dedicated servers or cloud hosting solutions often provide better performance compared to shared hosting.

Content Delivery Network (CDN): Utilizing a CDN can drastically reduce load times by hosting your site’s static assets (like images, JavaScript, and CSS) on multiple servers around the world, allowing them to be downloaded from the nearest server to a visitor.

Image Optimization: Large image files can slow down your website. Optimizing images for the web — by compressing them and adjusting their dimensions without significantly sacrificing quality — can help speed up load times.

Minification of CSS, JavaScript, and HTML: Removing unnecessary characters from your code (like whitespace, comments, and new line characters) can decrease file size and thus improve load time.

Browser Caching: By enabling browser caching, you can store some of the files of your website locally in visitors’ browsers. The next time they visit the site, these files don’t need to be loaded again, which speeds up the process.

Database Optimization: For dynamic e-commerce sites that rely on databases for inventory and customer data, optimizing database performance and structure can reduce the time it takes to query data.

HTTP/2: Modern HTTP/2 protocols can significantly improve the speed of your website compared to the older HTTP/1.1. HTTP/2 allows multiple files to be loaded in parallel over a single connection.

Use of Asynchronous Loading for CSS and JavaScript: This allows the webpage to render progressively, which means that parts of the web page can be displayed and functional while other parts are still loading.

Reduction of Redirects: Each time a page redirects to another page, your visitor faces additional time waiting for the HTTP request-response cycle to complete.

Load Balancers: In high-traffic scenarios, load balancers can distribute client requests across several servers, optimizing resource use and minimizing response times.

Mobile Optimization: Given the substantial number of users accessing sites via mobile devices, optimizing for mobile with responsive design or adaptive delivery can significantly enhance site speed and user experience.

Improving the speed of an e-commerce website involves multiple strategies and adjustments, and often requires ongoing monitoring and optimization to ensure the best performance.

Do’s for WooCommerce Performance

1. Get a reliable host

Web hosting is the most important factor affecting the speed of your WooCommerce store. All other factors can be tweaked by you. While other factors also play a major role in improving your store’s speed, none of them contribute as much as your hosting does. The resources allocated to you by your web host affect your store’s performance. A shared host is suitable for small businesses that are just starting out or don’t have lots of visitors. Once your store starts getting traffic it would be advisable to consider a VPS. If there are a large number of visitors and many products in your store then a dedicated server may be best suited. It is also important to read reviews and research about web hosts before choosing one. Not all dedicated servers are the same. Given the technicalities involved it may be best to discuss this with your web designer or developer.

2. Optimize Server Configuration

The way a server is configured can greatly affect your website’s speed. Key actions include:

• Enable Compression: Tools like Gzip can compress web pages, CSS, and JavaScript before they’re sent over to the browser. This can reduce their transfer size significantly, speeding up load times.
• Use Efficient Caching Mechanisms: Configuring server-side caching can help decrease load times dramatically. Techniques such as object caching, full-page caching, and opcode caching are effective ways to reduce the amount of data that needs to be processed and sent over the internet.
• Database Tuning: For e-commerce sites that frequently access the database for transactions, product information, and customer data, optimizing SQL queries and indexing can significantly reduce response times.

3. Leverage a Content Delivery Network (CDN)

Though not a hosting service per se, integrating a CDN with your hosting solution can immensely boost your site’s performance. A CDN stores copies of your site’s assets on a network of servers around the world, which means that users are always downloading data from a location that’s geographically close to them. This reduces latency and improves site speed. For an e-commerce platform, where images and product videos are prevalent, a CDN can make a noticeable difference.

4. Set up caching

Each time a visitor accesses your WooCommerce store, there are queries to your website’s database and several scripts are loaded. When there are many visitors this creates an unnecessary load on your database and results in slowing down your store. To overcome this you can set up caching. A cache is a static HTML copy of your web pages that are served to visitors. The database is only queried when required and scripts are also only run when needed. This reduces the load on your server, resulting in a better user experience for your visitors. In WordPress, caching can easily be set up via caching plugins. It is also important to ensure your web host supports caching. Many managed WordPress hosts do not support caching.

5. Use optimized images

Images are a significant part of any WooCommerce store. Search engines are going to hate your store if you don’t use optimized images. Avoid resizing images via HTML and CSS. It is better to crop and resize images using image editing software before uploading them. Images should be a few kilobytes and their dimensions should be exactly for the area required. There are numerous ways to resize and reduce the size of images without losing quality. Many WordPress plugins are also available to help you optimize existing images for your WooCommerce store.

Having unnecessary large images on your store will also slow it down, resulting in a poor user experience. Have you ever been in a situation, where the page has loaded and then images load slowly after that? You don’t want your visitors to end up in such a situation.

6. Optimize Your Database

Implement Strategic Indexing to Accelerate Query Performance: Properly indexed databases can dramatically improve the speed of data retrieval operations by allowing the server to quickly locate and fetch the necessary rows without scanning the entire table.

Optimize SQL Queries for Maximum Efficiency: By writing more efficient SQL queries, you can reduce the load on your database server. This involves selecting only the columns you need, using proper joins, and avoiding complex subqueries where simpler alternatives exist.

Regularly Clean and Maintain Database Health: Scheduling regular maintenance tasks such as cleaning up unused data, updating statistics, and checking for database integrity can prevent performance degradation over time. This proactive approach ensures that the database operates efficiently and remains robust and scalable under varying loads.

Don’ts for WooCommerce Performance

1. Overusing plugins

Plugins are a great way to extend the functionality of your website. However, having too many of them will slow down your website. Often there are compatibility issues between plugins and this can easily result in a broken website. For example, if you have 10 different payment gateways setup using plugins on your store, some of them will compete to display on top of others. This can result in your checkout page not functioning properly.

It is best to avoid using unnecessary plugins. Many times functionality can be achieved without the use of plugins by coding. For example, if you want to create a top bar on your website, you can do that via a plugin or you can also code this in your header.

Sometimes you will only need plugins temporarily, or when you want to perform a specific task. For example, when you want to optimize existing images. In such cases, you should delete the plugin after using it.

2. Improperly configuring cache plugins

Using caching plugins will significantly improve the speed of your website. However, in WooCommerce some pages should not be cached – such as My Account, Cart and the Checkout page. The content for these pages is unique for each customer and using caching for these can result in lost business.

Sometimes cache plugins tend to overdo their job. Most will try to combine scripts to one file. They will also minify the HTML and CSS of your store. Often this can affect your user interface. It is important to test what works and what does not work for your store.

3. Using an older version of PHP

It is extremely important to always use the latest version of PHP. Often this will not require any work and will be an instant performance boost. Older versions of PHP are gradually getting phased out. Older versions have security vulnerabilities as well. The chart below shows the difference in performance for various PHP versions. Clearly having the latest version of PHP boosts performance.

Conclusion

There are many other tweaks that you can still do – for example using optimized WooCommerce themes and keeping WordPress, WooCommerce and your plugins up to date. We have listed the most important do’s and don’ts for WooCommerce. Generally, people tend to have short attention spans and if your website performance and speed are not optimized, you will end up with a low conversion rate.
