Top 7 Ecommerce Website Testing Tools for Online Store

Page speed has an impact on your website performance in nearly every aspect, from user experience to search engine optimization. In one study, 40% of the subjects claimed that they would leave a webpage that takes more than 3 seconds to load. 

Actually, a one-second delay in page response can result in a 7% loss in conversion and 11% fewer page views. For a retail business earning $200,000 per day, that one-second delay might bring about a $5 million loss in sales annually.

Reducing your page load time can have a drastic impact on the overall success of your site, so it’s important to make sure you tune up the performance of your online store. 

However, before you make your ecommerce store lightning fast, you should measure the current performance of your store. There is a great variety of website speed test tools to ensure everything is functioning as it should. We compiled a list of the best 7 ecommerce testing tools for testing the performance of your online stores.

Why Does Your Website’s Speed Matter? 

Page load time is a web performance metric that defines the time required for a page to fully load in the browser. Website speed is an indicator of your website’s success as it affects your conversion, revenue, traffic, page views, and overall reputation.

Here are some more reasons why you should use ecommerce website testing tools to achieve a high speed for your online store.


The page load time of your store affects how easily customers can browse your website as it’s one of the key aspects Google takes into account when ranking sites. Google uses page load time in algorithms that identify search engine rankings, meaning the engine is more likely to rank higher websites that load fast. Plus, improved store speed means an increase in the number of pages Google can crawl and index. 

Better UX, Lower Bounce Rate

Even if your site eventually downloads after some awkward moments of waiting, it doesn’t mean customers will appreciate this snail’s pace. In fact, they will leave quite soon and address your more prompt competitors. 

How page speed affects bounce rate

Higher Revenue

It’s not only about the bounce rate. Optimizing your website to speed up the page load time will help you boost conversions and increase revenue. Every second of load time improvement at Whola ecommerce website equaled at least a 2% conversions increase and incremental growth in revenue.

Better Search Capability

Customers won’t buy the very first item they see on your site. As any sober-minded consumer, they would like to browse around and weigh all pros and cons before making a purchase. If it is a problem at your e-store, the odds are you will realize how testing is crucial in ecommerce only too late.

By tuning up your ecommerce store, you’ll get higher traffic and attract more leads that you can then convert into customers, eventually boosting your sales and generating more profit.

Ecommerce Site Testing Types Scrutinized

There are several ecommerce performance test types responsible for various aspects of your site’s operation.

Functional Testing

Ecommerce sites tend to have more functionalities than other site types, so meticulous testing of login/logout, filter, payments, search, and other indispensable aspects of an e-store can ultimately determine whether your first-time visitor will turn into your loyal customer. 

Ecommerce website testing tools that are a solid choice for functional testing are Selenium, UFT, TestComplete, Watir, and some others.

Security Testing

Customers must feel sure their personal and financial data are safe from unauthorized exposure, and all transactions they enter won’t lead to losing their money. Ecommerce security testing involves checking payment gateway, SQL injection vulnerabilities, and prevention of ethical hacking of login/register functions. Efficient tools used for this are ZAP, Wapiti, Vega, and Iron Wasp.

Performance Testing

Performance testing of ecommerce applications and sites ensures their minimal loading time. This is where your webpage loading speed is tested, which also includes data transfer rate, database performance, traffic load tolerance, throughput, etc. The two most popular ecommerce load testing tools are Load Runner and JMeter (and the latter one is open-source!).

Compatibility Testing

While launching your e-store, you must be sure customers can access it via any browser. Browsershots, Browsestack, and CrossBrowserTesting are the tools used to check there are no glitches in reaching your site across browsers. Another important part of compatibility testing is conditioned by the ubiquity of mobile phones that are increasingly growing into a very popular way of conducting online transactions.

Usability Testing

The success of your ecommerce site largely depends on how well a user can navigate around it (aka friendly user experience, or UX). Alongside foolproof site navigation, UX encompasses such summands as smooth checkout and payment, simplicity of filtering, clarity of content, the convenience of the shopping cart, and other minute details of website design and operation that make interacting with your e-store problem-free. 

A wise approach would be to combine several tools to do the job, like ClickHeat, Unbounce, Browsee, and Google Analytics Content Experiment.

Keep in mind: Any of these testing types can be implemented manually or automatically. While automation testing of an ecommerce website is certainly faster, it is not always the best option. For instance, initiating automation functional testing of ecommerce websites will not render proper results, since such sites have a lot of dynamic elements (product inventory, coupons, special offers) that are prone to change quite often. In such a case, the manual testing ecommerce website is what the doctor ordered.

7 Tools to Test Your Magento Store Speed 

Here is a list of seven free and premium tools to check how well your online store performs on the speed scale and identify the main performance issues.

Let’s start off with Page Speed Insights by Google. Google PageSpeed Insights is a free tool that helps you check the performance of your store.

Suggestions for optimization are based on general web performance metrics, including resource caching, data upload, and download size. 

All you need to get started is to enter the web address of your Magento store, wait a few seconds, and Google will analyze both mobile and desktop versions of your website. Suggestions are sorted by order of priority from high to medium or low priority. This can help you choose which steps to take first since they’ll have a bigger impact on your site in general. 

All the results are color-coded, so you are able to know right away whether your website is performing well or not. A score of 90 or above is regarded as fast, 50 to 90 is average, and below 50 is slow.
