Quality control is the final and most critical phase of website development. It’s the difference between launching a polished, professional site and discovering embarrassing bugs after going live. A thorough quality control process ensures your website functions correctly, looks great across all devices, and provides an excellent user experience from day one.
At TinyFrog Technologies, quality control isn’t an afterthought – it’s a structured process involving the entire team and our clients. This multi-stage review catches issues before they reach your visitors and ensures your website is ready for launch.
In this guide, we’ll walk through the five key quality control steps that should happen before every website launch, what to look for at each stage, and how to create a quality control checklist for your own projects.
What is Website Quality Control?
Website quality control is a systematic review process that verifies your website works as intended, looks professional across different browsers and devices, and provides a positive user experience. It’s the final checkpoint before launch that catches issues you might have missed during development.
Quality control covers:
- Functionality (forms, buttons, links, features)
- Visual consistency (design, layout, images, typography)
- Cross-browser compatibility (Chrome, Safari, Firefox, Edge)
- Mobile responsiveness (phones, tablets, different screen sizes)
- Performance (page speed, load times)
- Content accuracy (spelling, grammar, information)
- SEO setup (meta tags, redirects, sitemaps)
- Security (SSL, updates, backups)
Quality control isn’t just testing – it’s a collaborative review involving developers, designers, strategists, and clients to ensure nothing is overlooked.
Step 1: Internal Team Review
The first quality control step happens internally before showing the client anything. At TinyFrog, this involves the full project team: strategist, designer, developer, and development coordinator.
What the Team Reviews
Each team member brings different expertise:
Strategist checks:
- Value proposition is clear and prominent
- Calls to action are properly placed
- Navigation structure makes sense
- Content hierarchy guides visitors effectively
- Visitor profiles are properly addressed
Designer checks:
- Design matches approved mockups
- Typography is consistent
- Colors are accurate
- Spacing and alignment are proper
- Images display correctly
- Visual hierarchy is maintained
Developer checks:
- All functionality works as specified
- Forms submit correctly
- Plugins are configured properly
- No console errors or warnings
- Database is optimized
- Security measures are in place
Development Coordinator checks:
- Content is formatted correctly
- Links work and open appropriately
- Images have alt text
- SEO settings are configured
- Overall user experience flows smoothly
Why Internal Review Matters
Internal review catches obvious issues before clients see them, saving time and maintaining professionalism. It’s much better to catch a broken form or misaligned image internally than have a client point it out.
Step 2: Cross-Browser Testing
Different browsers render websites differently. What looks perfect in Chrome might have issues in Safari or Firefox. Read more about browser testing best practices for comprehensive coverage. Cross-browser testing ensures your site works consistently everywhere.
Browsers to Test
At minimum, test these browsers:
- Chrome (desktop and mobile) – 60%+ of web traffic
- Safari (desktop and mobile) – especially for Mac and iOS users
- Firefox – still significant, especially in certain industries
- Edge – growing Windows market share
Optional but recommended:
- Samsung Internet – default on Samsung phones
- Older browser versions if your analytics show significant usage
What to Check in Each Browser
- Layout and spacing (especially flexbox and grid)
- Fonts rendering properly
- Images displaying correctly
- Forms functioning
- JavaScript features working
- Animations playing smoothly
- CSS effects like shadows, gradients, transitions
Common Browser Issues
Safari has different date picker formats than Chrome. Firefox handles flexbox spacing differently. Edge may show fonts differently. These small variations can create big visual problems if not caught.
Step 3: Device and Screen Size Testing
Mobile traffic often exceeds 60% of total website visits. Your site must work flawlessly on phones and tablets, not just desktops.
Devices to Test
Test on actual devices when possible, not just browser resize:
- iPhone (multiple models if possible)
- Android phone (Samsung or Google Pixel)
- iPad or Android tablet
- Desktop/laptop at various screen sizes
- Large desktop monitors (1920px+ width)
What to Check on Each Device
- Text is readable without zooming
- Buttons and links are easy to tap (minimum 44x44px touch target)
- Images scale appropriately
- Navigation works (hamburger menu functions properly)
- Forms are easy to fill out on small screens
- Content doesn’t overflow or get cut off
- Horizontal scrolling doesn’t occur unexpectedly
- Page loads quickly on mobile networks
Responsive Breakpoints
Common breakpoints to test:
- 320px – Small phones
- 375px – iPhone standard
- 414px – Larger phones
- 768px – Tablets portrait
- 1024px – Tablets landscape / small laptops
- 1280px – Standard desktop
- 1920px – Large desktop
Portrait and Landscape
Don’t forget to test both orientations on phones and tablets. Layout that works in portrait might break in landscape.
Step 4: Performance and Speed Testing
Slow websites lose visitors and hurt SEO rankings. Performance testing ensures your site loads quickly across different connection speeds. Learn the 6 steps to optimize WordPress performance and speed for your website.
Performance Testing Tools
- Google PageSpeed Insights – Comprehensive performance analysis
- Gtmetrix – Detailed waterfall charts and recommendations
- WebPageTest – Advanced testing with different locations and speeds
- Pingdom – Simple speed monitoring
Key Performance Metrics
Largest Contentful Paint (LCP):
Should be under 2.5 seconds. Measures when main content loads.
First Input Delay (FID):
Should be under 100ms. Measures interactivity responsiveness.
Cumulative Layout Shift (CLS):
Should be under 0.1. Measures visual stability (elements shouldn’t jump around).
Total Page Size:
Aim for under 3MB. Smaller is better, especially for mobile.
Number of Requests:
Fewer is better. Each request adds overhead.
Common Performance Issues
- Unoptimized images (too large, wrong format)
- Too many plugins or scripts
- Render-blocking CSS and JavaScript
- No caching configured
- Slow server response time
- Too many fonts or font variations
Step 5: Functionality and User Experience Testing
This is the most comprehensive step. Every feature must be tested to ensure it works correctly and provides a good user experience.
Forms Testing
- All form fields work
- Required field validation functions
- Error messages display clearly
- Success messages appear after submission
- Email notifications arrive correctly
- Form data stores or sends as intended
- CAPTCHA works (if present)
- Auto-fill behaves properly
Navigation Testing
- All menu links work
- Submenus appear and function
- Mobile hamburger menu opens and closes
- Footer links work
- Breadcrumbs display correctly
- Search function works (if present)
Content Testing
- All text is spelled correctly
- Grammar is proper
- Phone numbers and email addresses are correct
- Dates and hours are accurate
- Internal links work

Client Review: The Critical Step
After internal testing, the client reviews the site. This is crucial because clients know their business, content, and audience better than anyone.
What Clients Should Review
- Content accuracy (especially details like prices, hours, services)
- Images are appropriate and high quality
- Branding feels right
- Messaging aligns with business goals
- Calls to action are positioned well
- Overall user experience feels smooth
- Any industry-specific requirements are met
Client Review Tips
For clients reviewing their website:
- Test on your own devices (phone, tablet, laptop)
- Fill out contact forms to see what you receive
- Navigate as a customer would
- Check all critical information (hours, pricing, contact info)
- Show it to team members for additional feedback
- Don’t just look for problems – confirm it meets expectations
Post-Launch Monitoring
Quality control doesn’t end at launch. Monitor the site for issues that only appear with real traffic. Avoid common post-launch website mistakes with proper quality control.
- Watch analytics for unusual bounce rates
- Monitor form submissions to confirm they’re working
- Check error logs for PHP or JavaScript errors
- Review user feedback or support tickets
- Test after plugin or WordPress updates
Frequently Asked Questions
Q: How long does quality control take?
For most websites, internal QC takes 2-4 hours and client review takes 3-5 business days. Complex sites with e-commerce or custom functionality may take longer. It’s better to be thorough than rush and launch with problems.
Q: What if we find issues during quality control?
Issues are expected – that’s why we have QC. Minor fixes (typos, small layout adjustments) are handled quickly. Major issues may delay launch but it’s always better to fix them before going live than after.
Q: Do we need to test on every possible device?
No. Test on the most popular devices and browsers based on your analytics. At minimum: iPhone, Android phone, iPad, desktop Chrome and Safari. If your analytics show significant traffic from specific devices or browsers, add those.
Q: Should we test on older browsers?
Only if your analytics show significant traffic. Most modern websites focus on current browser versions. Internet Explorer is effectively dead and not worth testing unless you have specific requirements.
Q: What’s the most commonly missed QC item?
Mobile experience. Many websites look great on desktop but have issues on phones: tiny text, hard-to-tap buttons, awkward layouts. Always test on actual mobile devices, not just browser resize.
Q: Can we skip quality control if we’re on a tight deadline?
Never skip QC. Launching with broken forms, poor mobile experience, or embarrassing typos damages your brand more than a short launch delay. If you’re tight on time, do abbreviated testing on the most critical features and devices.
