In this blog, I'll discuss how you can keep your website bug-free.

Ready launch a bug-free eCommerce website? Here are eight tips to help you build an error-free site:

1. Ensure the images are lightweight.

I have always emphasized the benefits of high-resolution images, but they also have bigger file sizes.

You don’t want Google to give your website a low ranking. Fortunately, you can minimize your image’s file size to improve your website’s performance. One issue with formatting your images is that adjustments often reduce their quality and the visitor may start to dislike your website. That’s not a bad thing as long as it doesn't shrink or looks distorted.

How to optimize your images without degrading the quality?

There are two kinds of image compression, it's called "lossy" and "lossless" technique.

Let me explain.

Lossy image compression happens you compress the image and it eliminates the data. As a result, it degrades the quality of the image.

Original: 1.7MB 6016 × 4016 | Lossy Compression: 20 KB 100 × 67

Tools you can use: Adobe Photoshop, Affinity Photo,


Lossless image compression reduces the data but it doesn’t degrade the quality but it will require the images to be uncompressed before they can be rendered.

Tools you can use: Photoshop, FileOptimizer, or ImageOptim, Compressjpeg.com, Compresspng.com

2. Initiate a code review to make your code faster.

Performing code review can bring in tremendous value to your website's performance. Six eyes are better than two. You should allow other developers to analyze your source code on a regular basis.

To assure the quality of the code is high, review the code first and then do the peer testing. It is easier to detect bugs during the code review than discover them during testing. Some of the bugs are usually in the newly-written code can be very difficult to detect by the tester.

Each line of code you write has to be maintained and reviewed from time to time. There is an extreme possibility in the future, someone will have to stare at your code and try to understand its purpose.

Some experts may have the notion that it doesn't matter how your code is written as long as it works, but this is not necessarily true. Badly-written code has a much higher maintenance cost than clean code.

3. CDN for worldwide traffic.

CDN or content delivery network refers to a geographically assigned group of servers which work together to render fast delivery of internet content. A CDN allows for a faster transfer of assets required for loading internet content including javascript files, HTML pages, CSS, images, and videos. The popularity of CDN services continues to grow, and today the majority of web traffic is served through CDNs, including traffic from major sites like Amazon, Facebook, and Netflix.

In essence, a CDN is a network of servers connected together with the goal of delivering content as fast, cheaply, reliably, and securely as possible.

CDN does help to improve website speed and helps to serve assets from a cache based server. The four benefits of having a CDN are:

  • Faster website load times.

Distributing the content closer to website visitors by using a nearby CDN server (among other optimizations), visitors experience quicker page loading times. As visitors are more likely to click away from a slow-loading site, a CDN can decrease bounce rates and boost the amount of time that people spend on the website. As a result, a faster a website means more visitors will stay and stick around longer.

  • Reduced bandwidth costs.

Do you know that bandwidth consumption costs for website hosting are a primary expense for websites? Through caching and other optimizations, CDNs are able to minimize the amount of data an origin server must provide, hence decreasing hosting costs for website owners.

  • Increased content availability and redundancy.

A huge chunk of traffic can disrupt normal website use. A CDN can handle more traffic and endure hardware crash better than many origin servers.

  • Better website security.

A CDN may improve security by implementing DDoS mitigation, improvements to security certificates, and other optimizations.

4. Never ignore Beta Testing.

Let’s talk about the value of beta testing and what role it place in improving the user experience to a different level.

Beta testing is one of the most critical phases of website development. It serves multiple purposes, yet all of those actions lead to one thing: better customer experience. It's about testing all the features in its final stage, meaning fewer errors are expected.

Beta testing evaluates all the complete features and includes all the features that are planned for the final or live version.

Online shoppers are smarter than ever because they know the options they have. If you fail to deliver a good user experience through your website, they would move on to your competitor and would never come back.

Beta testing aims to establish quality, performance, stability, security, and reliability. Skipping beta testing is like skipping the final airplane safety checks.

In general, beta testing is providing a finished or almost finished product to a handful of current or potential users to assess its performance in the real world.

5. Error Reporting.

Documenting all the errors you've encountered is good practice. Every report should include extensive data to help fix issues quicker. You need to include steps to replicate errors, network request, and console logs, and environment details. For bug reporting, it is also recommended to save screen recordings and annotate screenshots to give additional context.

6. Setup Test Environment.

It's a more complex process for website development. In building a bug-free eCommerce website, every process needs a controlled environment with the right specifications and requirements to carry out the commands of the intended tasks and activities.

No matter where you need to test, on your local machine, a virtual machine, against a dedicated test environment or against your production environment you have to make sure you are simulating the right conditions and other possible scenarios.

7. Use a Good Debugger.

Finding and fixing bugs in a website program code is known as debugging.

Good developers have an arsenal of tools to debug websites. Website errors can easily frighten anyone, especially if you are a business owner who invested in launching your website. Hence it is important to detect all those bugs to produce a seamless running website.

With the latest technological developments, the debugging in the browsers has become much easier. Currently, all the major browsers have built-in developer tools, you can easily activate the debugging tools in the following browsers:

  • Chrome Developer Tools (Chrome)

  • Firebug (Firefox)

  • Safari Developer Tools (Safari)

  • Dragonfly (Opera)

  • Yslow (Chrome, Safari, Firefox, Opera)

8. Customer Review.

After all the testings, you can soft-launch first to a select audience and seek feedback. The more feedback you receive the more insights you can have to improve the current version. This will also prepare you for a wider release. Just make sure to consolidate all the reviews and errors they reported. Be proactive and dedicate a team member who will monitor the situation.

Rigorous series of testing is the key to a bug-free eCommerce website. As a rule of the thumb, users only need a website that loads instantly, straightforward, has complete information and has a pleasing design. It’s necessary to understand what your target audience wants to better serve them and gain their trust.
