The Shopify Bug Fixes That Skyrocketed Conversions

Behind the scenes of a full-site QA audit that uncovered costly UX issues and turned missed opportunities into measurable growth

“We had no idea how many little things were hurting our conversions—until we worked with BadTesting.”
A behind-the-scenes story of how a DTC brand fixed dozens of hidden issues and saw real results.

If you’re running a direct-to-consumer business, you know how much effort goes into building a great-looking Shopify site. The photos are high-res, the branding is tight, and the products? Stellar. You pour so much time and money into creating something that feels premium.

That’s exactly where we were. We thought our site was in solid shape. The homepage looked clean, our checkout process seemed straightforward, and our product pages were optimized (or so we thought). But something wasn’t adding up—conversion rates on mobile were weirdly inconsistent, some customers were getting frustrated, and we kept getting these strange support messages like,

“Hey, I hit enter to search and nothing happened…”
or
“The button looks broken on my phone.”

We didn’t think it was a big deal at first. A one-off bug here, a little styling hiccup there. But it started to add up. And that’s when we decided to bring in BadTesting.

“They didn’t just find problems—they showed us how they were costing us sales.”

Within the first few days, the BadTesting team dove deep into our site. Not just surface-level stuff. They tested every page, every browser size, every device. They clicked every button, filled out every form, and did it all from the perspective of a real user—not a developer or a designer, but a customer.
What they found… was eye-opening.

Here are just a few of the things they surfaced:

• On multiple “Find Us” forms, pressing the Enter key didn’t submit the form. You had to physically click the “Go” button. That might seem small, but on mobile—where most of our traffic was coming from—that’s a friction point.
• Product pages had layout issues at specific screen widths—the “Add to Cart” button was misaligned between 992–1200px wide. That’s a common browser window size for tablets and smaller laptops. On those devices, the experience just looked… broken.
• Our newsletter modal had a design issue where a letter in our brand name looked like a different letter. This wasn’t just a pixel issue—it was a branding issue.
• On mobile, certain sections like the homepage progress bars didn’t work the same way they did on desktop. They created confusion instead of clarity.
• Our 404 page? No styling, no padding, no guidance. It felt like a dead end, not a “whoops, try this instead.”
• There were duplicate page titles, which isn’t great for SEO. And parts of the site didn’t display anything at all if a visitor had JavaScript disabled. Instead of showing a helpful message, the site just broke.

They found inconsistencies in our forms, accessibility issues, UI glitches, and more than a few weird little bugs—like one that caused our cart icon to behave strangely if someone added more than 100 items to it (yes, it happened).

It was like death by a thousand papercuts. None of these problems alone were killing our conversion rate. But together? They were definitely making the site harder to use, especially for the customers who were most ready to buy.

“Fixing the bugs wasn’t just about cleaning things up—it was about creating trust.”

The thing is, when a site doesn’t work the way someone expects, even in small ways, it makes them hesitate. And when people hesitate, they don’t click “Buy.”

That’s the biggest thing we took away from working with BadTesting.

They didn’t just show us a list of problems—they helped us prioritize what to fix first, what would have the biggest impact, and how to think through the customer journey like a real human, not just a designer or marketer. They even worked directly with our devs to make sure things were implemented cleanly and across all breakpoints.

The results?

We saw an immediate lift in engagement, especially on mobile. Bounce rates dropped on a few key product pages. We started getting fewer “weird bug” emails from customers. And most importantly, our conversion rate increased, especially in places where it had been underperforming.

It wasn’t some flashy redesign or an expensive new feature. It was the result of fixing the dozens of quiet little problems that were standing between our customers and the checkout button.

Would we do it again? 100%.

If you’re a DTC brand and you’re investing in traffic—whether that’s email, ads, SEO, or social—and you haven’t had someone really go through your site with a fine-tooth comb, you’re probably leaving money on the table.

BadTesting gave us confidence. They made our site faster, clearer, and easier to use. And that’s the kind of thing that builds trust and drives conversions.

“They weren’t just testers—they were advocates for our customers.”

Ready to stop losing customers to tiny bugs?

We highly recommend talking to BadTesting. You don’t need a full redesign. You need a second set of expert eyes that know what they’re doing and care about the same things you do: clarity, trust, and conversion.
