The Complete Website Launch Checklist
A website launch checklist helps project managers, developers and agency teams confirm that an approved website is ready for real users and search engines. It should cover more than design approval. Forms, redirects, tracking, security, backups, mobile behaviour and live-site indexing must all be tested before the project is considered complete.
Assign every check to a named owner and record the result. “Someone tested it” is not a reliable launch control.

Gate 1: Content and Brand Approval
Content should be reviewed in its final website layout, not only in a separate document. Check realistic mobile wrapping, buttons, legal links and market-specific information.
| Check | Normal owner |
|---|---|
| Final copy, images and downloads are approved | Client |
| Logo, colours, fonts and visual styles match the brand | Agency |
| Phone numbers, addresses and contact details are accurate | Client |
| Spelling, currency, dates and time-zone references suit the target market | Agency |
| Page titles, headings and calls to action are clear | Agency |
| Privacy, cookie and legal content has received appropriate review | Client/legal adviser |
Do not treat this checklist as legal advice. Privacy, consent and disclosure requirements should be verified for the client’s location, audience and technology.
Gate 2: Responsive Design and Accessibility
Test representative devices and viewport sizes rather than relying only on browser resizing. Important content and controls should remain usable with longer text and different screen dimensions.
| Check | Normal owner |
|---|---|
| Pages work across agreed desktop, tablet and mobile widths | Developer |
| Navigation, pop-ups and interactive elements work by touch | Developer |
| Keyboard focus is visible and follows a logical order | Developer |
| Headings, labels, links and buttons use appropriate elements | Developer |
| Images have suitable alternative text or are marked decorative | Agency |
| Forms include visible labels and understandable errors | Developer |
| Colour contrast and text readability meet the approved standard | Agency/developer |
Minor spacing differences may not justify delaying launch, but inaccessible navigation, unreadable content or controls that cannot be used should be resolved.
Gate 3: Functionality and Integration Testing
Test the complete user outcome, not only the visible interface. A form submission is not successful if the notification email never reaches the intended recipient.
| Check | Normal owner |
|---|---|
| Navigation, buttons and internal links reach the correct destinations | Agency |
| Contact and enquiry forms send, store and display confirmations correctly | Developer |
| Email notifications reach approved recipients | Agency/client |
| Search, filters, login and account functions work | Developer |
| Ecommerce, bookings or payments complete in the correct mode | Developer/client |
| Third-party APIs and integrations return expected results | Developer |
| Error messages provide useful next steps | Developer |
Use approved test accounts and remove unnecessary test data before launch.
Gate 4: On-Page and Technical SEO
A technically functional website can still lose organic visibility if redirects, canonical tags or indexing settings are wrong.
| Check | Normal owner |
|---|---|
| Every indexable page has a unique title and meta description | SEO specialist |
| One clear H1 and logical heading structure are used | Agency/SEO specialist |
| Canonical tags point to the intended live URLs | SEO specialist |
| Old URLs have been mapped to relevant new destinations | SEO specialist |
| XML sitemap contains only preferred indexable URLs | SEO specialist |
| Robots.txt does not block required live content | SEO specialist |
| Staging noindex directives are removed from the live website | Developer/SEO specialist |
| Analytics and conversion events fire in test mode | SEO specialist |
Submit the final XML sitemap through the appropriate search-engine tools after launch. Do not assume submission guarantees immediate crawling or ranking.
Gate 5: Security, Privacy, Backup and Access
Launch preparation should include recovery planning. A backup must be usable, accessible and created close enough to launch to support rollback.
| Check | Normal owner |
|---|---|
| A verified pre-launch backup is available | Developer |
| A rollback procedure and decision-maker are documented | Developer/agency |
| SSL works without mixed-content errors | Developer |
| Administrator access follows least-privilege principles | Developer |
| Temporary users and shared credentials are removed | Developer |
| Domain, DNS, hosting and licence access is documented | Agency/developer |
| Consent and privacy tools match approved requirements | Client/legal adviser |
Protect staging with authentication or another appropriate control. Search blocking alone does not prevent unauthorised visitors from accessing a staging URL.
Gate 6: Launch-Day and Post-Launch Verification
DNS and caching can make the website behave differently after deployment. Repeat critical checks on the real domain.
| Check | Normal owner |
|---|---|
| DNS changes and expected propagation are planned | Developer |
| Homepage, templates and critical journeys work on the live domain | Agency/developer |
| Forms, payments and integrations are retested | Developer/client |
| Redirects and canonical tags work on live URLs | SEO specialist |
| Analytics records approved test visits and events | SEO specialist |
| Uptime, errors and search visibility are monitored | Developer/SEO specialist |
| Client receives credentials, documentation and support contacts | Agency |
Continue monitoring during the first days after launch. Some problems appear only after real users, third-party systems and search crawlers reach the website.
Go/No-Go Decision
Delay launch when: the website cannot complete a critical user journey; forms or payments fail; SSL is broken; there is no verified backup or rollback plan; required pages remain blocked or noindexed; major redirects are missing; privacy approval is incomplete; or responsible stakeholders have not approved the release.
Minor cosmetic items may be recorded for post-launch improvement when they do not affect accessibility, functionality, security, compliance or essential brand presentation. The decision and accepted limitations should be documented.
Need an independent check? Arrange a pre-launch QA review before changing DNS or removing staging protection.

Frequently Asked Questions
How long should website launch testing take?
Testing time depends on website size, functionality, integrations and approval requirements. Allow enough time to correct issues and retest them before the scheduled launch. Complex ecommerce, membership or multilingual websites generally require more preparation than a small brochure website.
How can I check whether a live website is still noindexed?
Review page-level robots directives, HTTP headers, WordPress visibility settings and robots.txt. Check representative live URLs rather than only the homepage. Search-engine inspection tools can confirm the directives detected on each page after deployment.
Does every old URL need a redirect?
Redirect old URLs that have backlinks, search visibility, traffic or a relevant replacement. Map each address to the closest useful destination rather than sending everything to the homepage. URLs with no equivalent may appropriately return a genuine not-found response.
How do I verify analytics after launch?
Use real-time or debugging tools to confirm page views and important conversion events. Test cookie-consent behaviour where required, exclude internal traffic according to the analytics plan and ensure data is being sent to the correct property.
How long should a new website be monitored after launch?
Critical functions should receive close attention during the first days, followed by ongoing uptime, error, analytics and search monitoring. The exact period depends on traffic and complexity. Maintenance responsibility should be assigned before the launch project is closed.
