Launch day should be boring. If you work through a proper website launch checklist in the days before, going live becomes a routine switch rather than a scramble of discoveries: the form that sends nothing, the page that breaks on phones, the test page Google has already indexed. Most launch problems are small and entirely preventable.
This checklist groups the checks that matter most, in the order to do them. Tick them off on the staging version first, then repeat the critical ones immediately after the site goes live.
Content and Spelling Checks
Read every main page out loud once. It is slow, and it catches what screen reading misses: repeated words, placeholder text left behind, the wrong phone number in the footer. Check names, prices, opening hours and addresses against a trusted source document, not against another page of the same site.
- No lorem ipsum or “coming soon” text anywhere
- Contact details identical everywhere they appear
- All links read sensibly and point where their text promises
- Images display properly and carry sensible alt text
- Dates, prices and offers are current, with nothing expired still showing
- Spelling set to the right language variant for your audience
Pay special attention to the pages that carry enquiries. A single wrong digit in a phone number on the contact page design can quietly cost weeks of business before anyone notices.
Functionality: Forms, Search and Checkout
Test every interactive element as a real visitor would. Submit each form with realistic data and confirm the message arrives in the right inbox, lands in the right system and shows the sender a clear thank-you message. Test error states too: submit the form empty and with a wrong email format, and check the messages are helpful rather than alarming.
- Submit every form and confirm delivery to the correct address
- Check auto-reply emails, if any, for correct wording and branding
- Run the site search with common and misspelled terms
- For shops, place a full test order, including payment in test mode and a refund
- Test password reset and account emails if the site has logins
- Click every menu item and footer link on desktop and mobile
Devices, Browsers and Speed
Test on real devices where you can: at least one phone, one tablet and one desktop, across the browsers your audience actually uses. Emulators help, but a real thumb on a real phone finds layout problems nothing else does. Check that nothing overlaps, horizontal scrolling never appears and buttons are comfortably tappable.
Then run speed tests on the homepage and one heavy content page. Act on the big warnings, especially oversized images, using the methods in website speed optimisation. A launch is the cheapest moment to fix speed, before habits and content build up around slow pages.
SEO and Analytics Setup
Before you switch
- Every page has a unique title and meta description
- One clear H1 per page, with headings in sensible order
- The staging block on search engines is removed at launch, not before
- XML sitemap generated and ready to submit
- Redirects from any old URLs are in place and tested
- Analytics installed and recording test visits correctly
- Search Console property created, ready for the sitemap submission
If this is a redesign rather than a first site, the redirect checks become the most important item on this whole page. Any URL change without a redirect is lost traffic waiting to happen, and the details are covered step by step in our website redesign checklist.
Security, Legal and Backups
Confirm the SSL certificate is active so the site loads over HTTPS on every page without warnings. Change any default admin usernames, check that strong passwords are in place, and remove test accounts created during the build. Make sure the software, theme and plugins are fully updated on day one, so the site does not start life already behind.
Legally, the privacy policy, cookie notice where required, terms and any regulated wording should be live and linked from the footer. Check the business details shown match your official registration. Finally, take a full backup of the finished site before launch and store it somewhere separate from the hosting account. Set the regular backup schedule running from the same day, and fold these tasks into your ongoing website maintenance routine so they are never one-off efforts.
Accessibility Final Pass
Run a quick keyboard-only pass: tab through the homepage and one form, checking you can see where you are and reach everything. Check text contrast on the main colour combinations and confirm images that matter have alt text while decorative ones are marked as decorative. These basics protect real visitors and are far easier to fix now than after launch publicity drives traffic to the site.
The First 48 Hours After Launch
Going live is not the end of the checklist. In the first two days, repeat the form tests on the live domain, watch analytics for odd gaps, check Search Console for crawl errors and ask a couple of real customers to use the site and report anything odd. Keep developer support on hand during this window if you can. Small fixes made in the first 48 hours rarely make the news; the same faults found by customers a month later do.
Frequently Asked Questions
How long before launch should I start this checklist?
Allow several working days for a small site, longer for a shop or a large redesign. The checks themselves are quick; the time goes on fixing what they find, which is exactly the point of doing them early.
What is the most commonly missed launch check?
Form delivery. Teams test that a form can be submitted and forget to verify the message actually arrives in the right inbox. Always test end to end, inbox included.
Should I launch on a Friday?
Better not, unless support is available over the weekend. A midweek launch leaves working days to fix surprises while the whole team is around.
Do I need to tell Google when my site launches?
Submitting your sitemap in Search Console speeds up discovery, and requesting indexing of the homepage helps too. Beyond that, normal crawling takes over, especially if other sites link to you.
Conclusion
A calm launch is a tested launch. Print this checklist, work it in order on staging, then re-test forms, speed and analytics the moment the live site is up. When you are ready to start, book the checklist work into your diary today rather than leaving it to launch morning. Future you, fielding enquiries instead of bug reports, will be grateful.
