Why Is Performance Testing before Black Friday a Must?

Oct 5, 2022
9 min read

Black Friday and Cyber Monday are just around the corner, so it’s your last chance to take a look at your previous years’ business results and do the math. Together with Christmas sales, these three events make up for the peak load in Internet traffic. ECommerce and mobile apps endure the highest load and expect great profits.

In 2021, Cyber Monday garnered $10.7 billion, which makes it 1.4% less than in 2020 (falling for the first time ever!). However, it remains the biggest online shopping day of the year. Black Friday 2021 sales volume was $8.9bn, which is almost 20% more than the pandemic 2019, but down 1.3% from 2020.

The start of the pandemic had made online sales many times more important than the offline ones, and the rolled-out vaccines did not change the new habit in 2021: obviously, customers are still unwilling to shop offline, if avoidable.

Only 39.7% of the purchases on Cyber Monday were made with mobile applications. For years, the trajectory had been showing mobile on a course to surpass the 50-mark in share of online sales, but with more and more people working from home, the growth has slowed down. Consumers are using their desktops to shop and their phones to browse instead.

The eCommerce Landscape Has Shifted

Obviously, eCommerce is growing, and consumer confidence is growing, but user requirements are growing along, and that implies both web sites and apps. Website, software and mobile performance are more important now than ever.

According to Akamai, 49% of visitors expect the website to load in 2 seconds, and 30% – in 1 second. 50% of visitors would feel disappointed and visit a different website, if their expectations won’t be met, and 22% will never be back. Research by Dynatrace has shown that 75% of all mobile and tablet software users will not use a retailer’s website or app if these work slowly or are bugged.

If you don’t possess Amazon’s resources, the performance level such as pictured below can lead you to critical failures in peak hours, which in turn will result in losing revenues and clients.

Diagnose performance issues

This is why now is the time to satisfy your customers and make their online shopping experience convenient and flawless. Below, we’re quoting the amounts of lost revenues worldwide retrospectively, so that you could make up your mind yourselves, but trust us: crashes or delays in peak hours can make your business suffer.

Some of the craziest examples of revenues lost because of the fact that companies had not tested their systems performance beforehand happened in 2019. In 2020, we took a short break, since retailers collectively blew up the traditional start to the holiday shopping season. Instead of door-busting discounts, open doors on Thanksgiving and frenzied crowds, major players in the industry spread discounts throughout November and launched online sales events in October.

But the world has adapted to living with COVID-19 by now, and the season of 2021 brought every retail’s nightmare back to life. Office Depot went down for hours on Cyber Monday. Other major retailers such as Walmart, GameStop and Cabela’s also suffered tech woes during the peak shopping days of Cyber 5. More than 40 direct-to-consumer brands and retailers experienced crashes, freezes or slowdowns as shopping boomed starting on Thanksgiving.

Why You Can’t Afford to Skip Performance Testing

As for 2021, Adobe forecasted U.S. holiday sales online to hit $207 billion from Nov. 1 to Dec. 31, setting a new record and showing a 10 percent increase from 2020. In fact, that year turned out to be even more generous: sales reached $211.41 billion. 2021 was an undeniably outstanding year for retail sales. Imagine what 2023 can bring to your business.

Actually, Deloitte has already forecasted it for you. They expect eCommerce sales to grow by 12.8% to 14.3%, year-over-year, during the 2022-3 holiday season. This will likely result in eCommerce holiday sales reaching between $260 billion and $264 billion this season, January 23 included.

On average, a consumer in the U.S. will spend 12 full hours shopping online this holiday season. During the “golden hours” of eCommerce (7:00–11:00 pm PT on Cyber Monday), shoppers will spend nearly $3 billion online ($2.9B) in just 4 hours, 50 percent more than a typical full day in August 2021 ($1.9B). In the peak hour of Cyber Monday (8:00–9:00 pm PT), consumers will spend over $12 million every minute.

Get seated and try to count how much it will cost you if your website crashes for mere 15 minutes, or if 30% of your visitors leave the app due to unexpectedly slow response. Are you sure your website or app’s performance is better than those of, say, Costco’s?

To avoid Black Friday discontent, you simply must start fixing and preparing the performance of your website and mobile applications BEFORE the date. And don’t forget that Black Friday and Cyber Monday only start the holiday season.

Tips for Having a Successful Black Friday & Cyber Monday

The checklist we give our clients for performance testing before sales, especially such peak sales as Black Friday and Cyber Monday, includes just a few points:

  • Start early. This way, you’ll have time to fix every bottleneck found while testing before high season starts. There are many tools to test your performance right now, including PFLB Platform
  • Ask for qualified QA help to figure out the reasons behind test results. What is slowing down your system? Are the pictures in the mobile version too large? Is your video ad slowing down the TTI by 2? How many simultaneous users can shop? Is this as many as you expect on holidays, or less?
  • Don’t run tests during peak hours. You don’t want your customer to be in the middle of a transaction when the system freezes.
  • Prioritize. If you don’t have enough time to test everything, test the most visited pages or the maximum load your system can handle. This way, you’ll be able to redesign your campaign to reduce or split the load users create.
  • Don’t get lost in an endless number of different testing tools. Our Top 10 performance and load testing tools list will save you time.
