Imagine this: It’s mid-December, and your e-commerce site is bustling with holiday shoppers. Suddenly, something breaks—a glitch at checkout, a navigation issue, or a coupon code that won’t apply.

Instead of enjoying the peak sales season, you’re scrambling to fix problems that could have been avoided with early user testing.

Here’s how user testing impacts the success of your eCommerce site.

Catch Problems Early

Waiting until November to test your site is like buying a snow shovel after the first storm hits.?️

By then, it’s too late…

“Testing with one user early in the project is better than testing with 50 near the end.”
— Steve Krug

Early user testing allows you to identify potential issues—like a broken product filter on mobile or a hard-to-find ‘add to cart’ button—before they become major obstacles during the holiday rush.

The Impact of User Testing on eCommerce sites

Studies show that normal websites can increase desired metrics by 135% on average following a usability redesign.

A well-known example from Jared M. Spool involved an eCommerce site where user testing revealed a critical issue during the checkout process.

By replacing the “Register” button with a “Continue” option and removing the mandatory account creation step, the site saw an increase in sales by 45%, resulting in an additional $15 million in the first month, and ultimately $300 million in revenue over time.

You can easily calculate the return of investment for your own usability activities if you keep track of about just a couple of your business metrics.

But if you skip early testing and encounter a major bug in December, fixing it quickly will be nearly impossible…

Your developers will be stretched thin, and the downtime could cost you thousands (or even millions)in lost sales.

Even worse, frustrated customers may turn to your competitors, making it difficult to win them back…

When Should You Start?

The best time to start testing was six months ago—the next best time is today.

Early testing allows you to catch and fix issues before they escalate, ensuring your site is ready to handle the holiday rush with ease.

There might be a few reasons holding you back, but don’t worry—there’s a solutions to address those concerns:

Unsure What You Should Test?

To prepare your site for the holiday rush, focus on the “conversion critical” areas—those red routes that directly impact your sales.

This includes:

  1. The checkout process
  2. Finding products and
  3. redeeming coupons, especially for seasonal promotions.

These are the areas where any friction can lead to lost sales, so they should be at the top of your testing list.
