Is Your Website Costing You Customers?

Here’s How Testing for Responsiveness & Functionality Fixes That

In today’s digital world, your website isn’t just a portfolio — it’s your storefront, your marketing engine, and your first handshake with new customers.

Yet, 61% of users say they’ll leave a website if it’s not mobile-friendly or if they experience broken functionality.
Translation?
👉 A beautiful homepage doesn’t matter if buttons don’t work, pages load incorrectly, or the layout breaks on mobile.

That’s why professional website testing services — covering responsiveness, design accuracy, and web app functionality — are critical before (and after) launch.

At Testers HUB, we help businesses across the US, UK, UAE, and Australia avoid costly mistakes by ensuring their websites and web apps work seamlessly — everywhere.

🚨 The Silent Revenue Killer: Poor Website Quality

Here’s the harsh truth:

• If your contact form fails, you lose leads.

• If checkout is buggy, you lose sales.

• If the mobile layout is broken, you lose trust.

And it happens more often than you think.

Real-world examples we’ve caught:

• Payment buttons working on desktop, but failing on Android Chrome.

• Pricing tables collapsing on smaller iPhones.

• Form validations missing on Safari, allowing garbage submissions.

Good QA doesn’t just prevent bugs — it protects your brand credibility and conversion rates.

🔍 What Comprehensive Website Testing Should Cover

When we test websites and web apps at Testers HUB, here’s the framework we follow:

🛠️ 1. Functionality Testing

Ensures that all features work correctly across scenarios:

• Navigation links and menu toggles

• Contact forms and signup flows

• Product filters, searches, sorting

• Shopping cart and checkout processes

• Login, forgot password, profile management in web apps

Bonus: We simulate invalid user behavior too — because real users often don’t follow a perfect path.

📱 2. Responsive Design Testing

Today’s users access your site across dozens of device types — from wide monitors to tiny smartphone screens.

We validate:

• Layout scaling on desktops, tablets, and smartphones

• Image optimization (no stretched or cut-off images)

• Mobile navigation menus

• Readability of fonts and button sizes

• Orientation behavior (landscape/portrait)

If your mobile site isn’t tested separately, you’re already losing half your audience.

🌐 3. Cross-Browser Compatibility Testing

Different browsers render sites differently. That’s why we test on:

• Chrome (desktop + Android)

• Safari (Mac + iOS)

• Firefox

• Microsoft Edge

• Opera and Brave (if needed)

We check:

• CSS/HTML rendering issues

• Modal behavior

• JavaScript errors in the console

Payment integrations across browsers

🚀 4. Web App Flow Testing (For SaaS or Membership Sites)

If your website is more than static — like a SaaS dashboard, client portal, or booking system — we dig deeper:

• Multi-step form behavior

• User account creation and management

• Subscription management flows

• API error handling

• Data validations and save/load functionalities

We focus not only on what works, but what could break under real usage conditions.

📈 5. Performance & Speed Testing

Even if your site is technically correct, slow load speeds kill conversions.

We test:

• Time to First Byte (TTFB)

• Page load times under 3G/4G networks

• Image compression and lazy loading

• Asset minification (CSS, JS)

Tools we use: Google Lighthouse, GTmetrix, WebPageTest

🧠 Real Example: Design Misalignment Costing Sales

Client: Fashion eCommerce brand (UK market)
Problem: Bounce rates increased after a new site launch.
Finding: On mid-range Android phones, the product “Add to Cart” button was hidden under the page fold — users didn’t even realise it existed.

Fix: Responsive retesting, UX adjustments, and retesting after corrections.
Result: Bounce rates dropped by 35%, cart additions improved by 50% within 3 weeks.
