You've built your website. You've written the copy, chosen the images, and set up your contact forms. Now comes the moment that's equal parts exciting and terrifying: hitting "Launch."
But here's the uncomfortable truth: most small business websites go live with at least one critical problem. A broken contact form that silently loses enquiries. A mobile layout that makes text unreadable. A missing privacy policy that technically violates UK law. These aren't hypothetical scenarios—they're the most common launch-day disasters I see every single week.
The difference between a confident launch and a stressful one isn't luck. It's this final verification step. Think of it as your safety net—a systematic check that catches the problems before customers do.
This 25-point checklist is your launch insurance policy. It takes 45 minutes to complete, and it will save you from the embarrassment (and lost revenue) of discovering critical issues after you've already announced your new site to the world.

Short on time? These five checks catch 90% of launch-day failures. If you can only do five things before going live, make it these:

Prerequisites Check
This builds on ensuring all legal components are complete, as outlined in Privacy & Cookies: What You Actually Need (UK Guide). Before starting this checklist, confirm your core content and legal pages are actually published, not just drafted.
1. Test Your Primary Navigation
Click every single link in your main menu. Does each one take you to the correct page? Does anything lead to a 404 error or blank page? This sounds obvious, but broken navigation is the number one complaint from new website visitors.
2. Submit Your Contact Form (And Verify the Email)
Fill out your main contact form with your own details. You need to verify two things:
If the form submits but you never receive the email, your site looks functional but is silently losing every enquiry. This is a launch-killer.
3. Check Mobile Display
Pull out your phone right now. Visit your homepage. Can you read all the text without zooming? Do images fit the screen? Does the menu work? Over 60% of your visitors will see the mobile version first—if it's broken, you've lost them.
4. Verify Legal Pages Are Accessible
Scroll to your footer. Can you see and click links to your Privacy Policy and Terms & Conditions? These aren't optional for UK businesses, and they must be easily accessible from every page.
5. Test Your Primary Call-to-Action
Click the main button on your homepage (usually "Contact Us," "Book Now," or "Get a Quote"). Does it work? Does it take you where it should? Your entire website exists to drive this action—if it's broken, nothing else matters.

These checks ensure your content looks professional and drives action.
☐ 1. Spell-check every page
Read through your Homepage, About, Services, and Contact pages. Use a browser spell-checker or read aloud to catch errors. Typos undermine credibility instantly.
☐ 2. Verify all images load and look professional
Check that every image displays correctly (no broken image icons), appears sharp (not pixelated), and is relevant to the surrounding content. Stock photos should look natural, not obviously staged.
☐ 3. Confirm clear calls-to-action on every page
Each page should tell visitors what to do next. Look for obvious buttons or links like "Contact Us," "Book a Call," or "Get a Quote." If you're not sure what action to take, neither are your visitors.
☐ 4. Check all headings make sense in isolation
Read just the headings on each page (ignore the body text). Do they tell a coherent story? Visitors often scan headings first—if they don't make sense alone, you'll lose attention.
☐ 5. Verify contact details are visible and consistent
Your phone number, email, and address (if relevant) should appear in the same format everywhere they're mentioned. Check the header, footer, and Contact page for consistency.
---
This is where silent failures hide. Every interactive element must be tested end-to-end.
☐ 6. Submit every form and verify email receipt
For each form on your site (contact, newsletter, quote request), submit a test entry using your own email address. Confirm you receive the submission email. If you're not getting emails, see our guide to setting up contact forms for troubleshooting steps.
[MEDIA:SCREENSHOT:working-contact-form-confirmation]
Always verify both the on-screen success message and the subsequent email receipt.
☐ 7. Test booking widgets or calendars
If you use a booking system (Calendly, Acuity, etc.), make a test booking. Verify the confirmation email arrives and the appointment appears in your calendar correctly.
☐ 8. Verify payment links or checkout processes
If you sell anything online, complete a test purchase using a test payment method (most payment processors offer test modes). Confirm the payment processes and you receive order confirmation.
☐ 9. Check all external links open correctly
Click every link that points to external websites (social media, partner sites, resources). Verify they open in a new tab and lead to the correct destination.
☐ 10. Test newsletter signup (if present)
Subscribe to your own newsletter. Confirm you receive a welcome email and can see yourself added to your email marketing platform.
☐ 11. Verify file downloads work
If you offer any downloadable resources (PDFs, guides, price lists), click each download link and confirm the file opens correctly.
---
UK legal requirements aren't optional, and trust signals directly impact conversion rates.
☐ 12. Confirm Privacy Policy is published and linked
Your Privacy Policy must be accessible from every page (typically in the footer). Click the link and verify the page loads with your actual policy, not placeholder text.
☐ 13. Verify Terms & Conditions are accessible
Same as above—T&Cs should be linked from the footer and contain your real terms, not template text.
☐ 14. Check cookie consent banner appears (if required)
If you use cookies beyond essential ones (analytics, marketing), a consent banner should appear on first visit. Test in an incognito window to see the first-time visitor experience.
☐ 15. Verify trust signals are visible
Look for professional indicators like client logos, testimonials, accreditations, or security badges. These elements build credibility—confirming those crucial trust signals are present can significantly impact conversion rates.

These behind-the-scenes elements affect findability and your ability to measure success.
Not sure you've covered the technical prerequisites, or if you have hidden broken links? NetNav's rapid audit checks fundamental issues like broken links, speed bottlenecks, and basic SEO structure in under 60 seconds.
☐ 16. Run a broken links check
Use a free tool like the W3C Link Checker or a browser extension to scan for broken internal links. Every link should lead somewhere valid. For a comprehensive approach, see Fix Broken Links and Images.
☐ 17. Verify Google Analytics is tracking
If you've installed GA4, visit your site then check your Analytics dashboard (Real-Time report) to confirm the visit was recorded. If you haven't set this up yet, see basic tracking with GA4.
☐ 18. Check every page has a title tag
View the browser tab for each page. Does it show a descriptive title, or just "Untitled" or your domain name? Each page needs a unique, descriptive title.
☐ 19. Verify meta descriptions are present
While you can't see these directly, check your website builder's SEO settings for each page. Every page should have a unique meta description (the text that appears in search results).
☐ 20. Confirm favicon appears
Look at your browser tab. Do you see your logo or a custom icon, or just a generic browser icon? A favicon is a small but professional touch.
Manually checking every single link and image is tedious and prone to error. This is one of the crucial technical checks NetNav runs automatically across your entire site, flagging broken elements instantly so you can focus only on the content and functionality checks.
---
More than half your visitors will use a mobile device. If the mobile experience is broken, you've lost the majority of your potential customers.
☐ 21. Test on an actual mobile phone
Don't just resize your browser—grab your phone and visit your site. Check the homepage, a service page, and the contact page. Is text readable without zooming? Do images fit the screen? Does the menu work?
[MEDIA:SCREENSHOT:mobile-testing-simulators]
Use built-in developer tools or simple browser resizing to check mobile responsiveness quickly.
☐ 22. Check both portrait and landscape orientations
Rotate your phone. Does the layout adapt sensibly, or does content get cut off? Both orientations should be usable.
☐ 23. Test on a tablet (if possible)
Tablets represent a middle ground between mobile and desktop. If you have access to an iPad or Android tablet, do a quick check. For a more thorough approach, test your website on multiple devices.
---
Speed directly impacts both user experience and search rankings. You don't need perfection, but you need "good enough."
☐ 24. Run a speed test
Visit Google PageSpeed Insights and test your homepage. You're aiming for a mobile score of at least 50/100 to launch now. Below that, you need to address critical issues first. For optimization strategies, see optimize your site speed.
☐ 25. Check in a different browser
If you normally use Chrome, test in Firefox or Safari. If you use Safari, test in Chrome. This catches browser-specific display issues. You don't need to test every browser, but checking one alternative is sensible.

Common Launch-Day Issues
Problem: Contact forms submit but emails never arrive
This is the most common and most dangerous issue. The form appears to work (visitors see a success message), but you never receive the enquiry.
Solution: First, check your spam folder—seriously, check it. If nothing's there, the issue is usually with your form's email settings. Check:
Most website builders have a "test email" feature in form settings. Use it. If test emails don't arrive, contact your website builder's support before launching.
Problem: Website looks broken on mobile
Text is tiny, images overflow the screen, or the menu doesn't work on phones.
Solution: This usually means your theme or template isn't mobile-responsive. Quick fixes:
If the issues are severe, you need to fix them before launch, not after. Over 60% of visitors will see the mobile version first—a broken mobile site means a failed launch.
Problem: Not sure if the speed is "good enough"
You've run PageSpeed Insights and got a score of 45/100 on mobile. Should you delay launch to fix it?
Solution: A score of 50+ is acceptable for launch. Below 40, you should address the most critical issues first (usually image optimization). Between 40-50, it's a judgement call based on your industry.
The key insight: speed optimization is ongoing work. You don't need a perfect score to launch—you need "good enough" now, with a plan to improve in Stage 6 (Get Better). Launch first, optimize second.
