Website Launch Checklist: 45 Checks Before and After Going Live
A successful website launch is more than pressing Publish. Before a new business website goes live, its pages, forms, analytics, SEO settings, mobile layouts, structured data, backups, security and conversion paths should all be ready to work together. This checklist gives teams a practical launch sequence instead of relying on memory.
Why a website launch checklist matters
A website can look finished while still being operationally unready. A contact form may not deliver email. Analytics may not record enquiries. Production may inherit a staging noindex rule. A canonical tag may still reference the development domain. A mobile menu may overlap the primary CTA. The sitemap may omit new service pages.
These problems are easy to miss because different people often own design, content, SEO, hosting and business approvals.
Phase 1: Business and content checks before launch
Decide whether the site should generate calls, WhatsApp enquiries, forms, purchases, bookings, applications or another measurable action.
Visitors should be able to reach important services, products, locations and contact options without understanding your internal company structure.
Prioritise homepage, service pages, product pages, contact information, pricing, policies and conversion pages.
Phone numbers, email addresses, WhatsApp, addresses, hours and legal/business names should be consistent.
Search for lorem ipsum, sample testimonials, template pricing, demo images, test products and temporary links.
Confirm the business is allowed to use the images, logos, fonts, videos and other media included in the site.
Depending on the business, this can include privacy, terms, refunds, shipping, disclaimers, cookie information and required regulatory disclosures.
Decide who can update pages, publish new content, approve changes and maintain factual accuracy.
Phase 2: UX and mobile launch checks
Review navigation, hero sections, buttons, forms, accordions, tables, sliders, sticky elements and popups at real mobile widths.
Buttons should be visible, understandable and connected to the intended next step.
Verify the correct number opens and that mobile visitors can act without copying contact details manually.
Body copy, headings, form labels and buttons should remain legible without zooming.
Important navigation and controls should remain usable for visitors who do not rely on a mouse.
Describe useful images appropriately while leaving decorative visuals out of unnecessary keyword-heavy alt text.
Phase 3: Forms, leads and conversion checks
Do not stop after seeing a success message. Confirm the enquiry reaches the correct inbox or CRM.
The visitor should know the submission worked and what will happen next.
Where relevant, check cart, checkout, payment, confirmation email, tax, shipping, booking availability and account flows.
Protect forms without creating unnecessary friction for genuine visitors.
Make sure someone is responsible for monitoring and responding to incoming enquiries after launch.
Phase 4: SEO launch checklist
Important pages should have distinct intent instead of several URLs competing for the same topic.
Titles should accurately describe the page and remain distinct across important URLs.
The main topic should be obvious and supporting sections should help users scan the page logically.
Canonical tags should reference the intended production URLs, not a staging environment or obsolete domain.
Production should not inherit development controls that prevent indexing.
Make sure important resources are not unintentionally blocked.
The sitemap should contain canonical, indexable production URLs you actually want search engines to discover.
Important service and conversion pages should receive useful contextual links and not be buried several clicks deep.
Schema should match visible page content and real business entities. Validate relevant markup before relying on it in production.
Google recommends making pages accessible to crawling, validating structured data, testing live pages with URL Inspection, and keeping Google informed through a sitemap. Google also notes that discovery and re-indexing can take time after publication. See Google Search Central structured-data guidance.
Phase 5: Performance and technical checks
Prioritise high-value templates and mobile performance rather than chasing one perfect score on a single page.
A new site should not ship with oversized hero images and unnecessary media weight.
Analytics, chat, ads, videos and marketing tools can materially affect page responsiveness and loading.
Check certificates, forced HTTPS behaviour and mixed-content warnings.
Crawl the production-ready site for broken internal links, missing assets and incorrect navigation destinations.
Before launch, know how the site can be restored if a deployment causes a serious issue.
Phase 6: Analytics and measurement checks
Confirm the live domain is sending data and that internal/test traffic is understood.
Track the business actions that matter: form submissions, calls, WhatsApp, checkout, booking or other meaningful actions.
Add the correct property and make sure the business controls access.
Submission does not guarantee immediate indexing, but it helps Google discover the URLs you want crawled.
Save initial traffic, impressions, conversions and performance so future changes can be measured against something real.
Phase 7: Launch-day checklist
Check the production domain in a fresh browser session and on mobile data where practical.
Test the most commercially important journeys after launch—not only in staging.
Confirm they return 200, use the intended canonical, are indexable and load the correct metadata.
Make sure live visits and conversion events are arriving as expected.
A launch can expose capacity, PHP, database or integration problems that did not appear during lower-traffic testing.
Keep one list of what needs correction, who owns the fix and whether the issue blocks marketing activity.
What to monitor during the first weeks after launch
Watch indexing, important queries, page visibility, crawl issues and unexpected drops.
Review landing pages, traffic sources and whether important events are being recorded consistently.
Check that enquiries and transactions reach the business and are being handled correctly.
Observe real-world speed and responsiveness after third-party scripts and live content are active.
Watch 404s, broken links, server errors, email-delivery failures and user-reported issues.
Move the website into an ongoing update, backup, security and content-review routine.
After launch, use the WordPress Website Maintenance Checklist to shift from launch mode into ongoing operations.

What should block a website launch?
Not every imperfection needs to delay go-live. Separate true blockers from improvements that can be scheduled after launch.
Broken forms/payments, staging noindex on production, SSL errors, major mobile breakage, wrong domain/canonical, missing critical content, legal/compliance blockers.
Important metadata gaps, broken secondary links, analytics-event issues, slow key pages, inconsistent CTAs, missing internal links.
Minor visual refinements, non-critical copy improvements, secondary schema enhancements, lower-priority content expansion.

Frequently asked questions
What should be checked before launching a website?
Check content, navigation, contact details, forms, mobile layouts, HTTPS, speed, indexing settings, canonical URLs, metadata, sitemap, structured data, analytics, conversion tracking, backups and legal/policy requirements relevant to the business.
How do I get a new website indexed by Google?
Make sure pages are accessible to crawling and not blocked by noindex or login restrictions, verify Search Console, use URL Inspection for important pages where appropriate and submit a sitemap containing canonical URLs you want discovered.
Should I submit a sitemap before or after launch?
Prepare it before launch, then submit the production sitemap after the live site is accessible and its URLs are final.
Can a website launch with some unfinished pages?
Sometimes, but do not publish placeholder or misleading pages merely to make the site appear larger. Launch the pages that are useful and accurate, then expand deliberately.
What is the difference between a website launch and a website migration?
A launch can be a completely new website. A migration involves replacing or moving an existing website and therefore needs additional work to preserve URLs, redirects, links, content and existing search signals.
How quickly will Google index a new site?
There is no guaranteed timeline. Google notes that crawling and indexing can take time after publishing, even when the site is accessible and a sitemap has been submitted.
