Website Launch Checklist: X Tests Every Agency Must Do
Simran July 31, 2025 11 views


Every website launch is a make-or-break moment for performance, perception, and business impact. For digital agencies, this isn’t just a handoff; it’s the final checkpoint of countless hours of planning, designing, coding, and testing.

The slightest overlook of a broken link, slow loading, or a missing tag can chip away at a brand’s credibility before the site even gets a chance to perform.

At RepIndia, we treat website launches as high-stakes deliverables. And like with any high-impact launch, a strong checklist ensures nothing is missed.

From the visual layout to real-time performance, every element must work in harmony to deliver a smooth, secure, and engaging user experience.

Here’s a comprehensive checklist that every agency should run before pushing a website live

1. Check All Links and Buttons Functionality

It may sound basic, but it’s often missed. Every single link, navigation menu, social icon, and button must be tested. A broken CTA on the homepage or footer can derail user trust in seconds.

Internal links, external references, and anchor navigations all play a role in keeping the site experience flowing.

Nothing frustrates a visitor more than a 404 error or an unresponsive link. So test links on both desktop and mobile versions to catch inconsistencies that may otherwise go unnoticed during development.

2. Test the Website on Multiple Devices and Browsers

Different users browse differently. What looks perfect on a MacBook in Chrome might fall apart in Firefox on Windows or fail to render correctly on Android.

A thorough cross-browser and cross-device test ensures consistency in appearance and functionality.

The aim is to deliver consistent web page design across platforms, ensuring that design intent translates smoothly regardless of how or where the user lands.

Use emulators and manual testing; both automation and manual testing can miss details that human eyes will catch.

3. Verify Page Load Speed on Key Pages

Speed is not a design feature, but it may as well be. If a webpage takes too long to load, users won’t wait; they’ll bounce.

Run page speed audits using tools like Google PageSpeed Insights, WebPageTest, or GTmetrix. Focus especially on the homepage, landing pages, and any product or service pages. Optimise large images, minify scripts, and ensure caching policies are in place.

4. Conduct Final UX Testing with Real Users

Good design isn’t always obvious to those building it. That’s why we always suggest a round of user testing just before launch. Ask people unfamiliar with the project to perform tasks on the site, such as finding contact details, navigating to specific services, or submitting a form.

These sessions will highlight real-world interaction challenges that might not be visible in regular UX testing. Even the smallest insight can lead to a significant usability improvement.

5. Double-Check Mobile Responsiveness

A large portion of traffic comes from mobile devices. If your site isn’t mobile-optimised, it isn’t really ready. Responsive design goes beyond layout. Test whether form fields are easily tappable, whether fonts are readable, and whether scrolling behaviour is natural.

We focus heavily on delivering a clean mobile experience to ensure that even on small screens, the site reflects the best website design practices like clarity, speed, and control.

6. Confirm SEO Readiness Before Going Live

No point launching a site that search engines can’t index. Basic SEO elements must be set up correctly, like title tags, meta descriptions, heading hierarchy, alt tags for images, and clean URLs.

Also, ensure that the XML sitemap is accurate and that the robots.txt file isn’t accidentally blocking search engines. Post-launch SEO fixes can delay visibility and impact rankings, so it’s best to get it right before the site goes live.

7. Ensure All Forms Work and Are Integrated

Forms are the gateway for leads, signups, feedback, and contact requests. So they must not just look good—they must work.

Before launch, test all forms thoroughly. This includes checking validation messages, error handling, submission responses, and integrations with backend systems like email notifications or CRMs. If a form doesn’t send data where it should, it’s a missed opportunity.

8. Review Content for Final Edits and Formatting

Even after content approval, there’s always something small, such as a missed punctuation, a layout issue on mobile, or a misaligned heading. That’s why a final staging review is a must.

We’ve learned from experience that viewing live content on a staging server can surface issues that go unseen in drafts. It’s also a good time to double-check any embedded media, file downloads, or rich content sections.

9. Set Up Analytics and Conversion Tracking

A website that doesn’t measure user behaviour is flying blind. Ensure that Google Analytics (preferably GA4), Tag Manager, and any additional tools are properly installed and firing correctly.

Also, confirm that all major events are tracked, including clicks, scroll depth, button taps, and form submissions. This is critical for marketing and performance measurement once the site is live. It also helps refine the design post-launch based on actual user activity.

10. Validate Site Security Measures

Security is non-negotiable. Ensure SSL certificates are properly installed and redirect all HTTP to HTTPS. This applies especially to sites collecting sensitive data such as logins, payment details, or contact forms.

Beyond SSL, consider running a quick vulnerability scan and making sure admin panels are protected. Launching without adequate security damages credibility and leaves the site vulnerable to early threats.

11. Review Accessibility Compliance

Accessibility ensures that everyone, including users with disabilities, can access the site. Check for colour contrast ratios, alt text for images, and keyboard navigation support.

Implementing accessibility enhances user experience while supporting legal compliance and SEO. While it’s easy to overlook, it’s a fundamental part of delivering inclusive digital experiences.

Launching a website is the final mile in a long, creative sprint. But that mile can define how the entire journey is remembered. We’ve seen that paying attention to these small details makes a massive difference in how users perceive a brand from the very first click.

By following this checklist, we reduce post-launch fixes and build a culture of reliability, consistency, and impact. And in a competitive market like ours, especially for a website designing agency in Delhi, that’s the difference between average delivery and exceptional digital experiences.
