Corporate Website Launch Acceptance Checklist

In the final days before launch, teams often fall into an inefficient cycle of "reviewing the pages again." Designers check spacing, developers check functions, and marketing checks copy, but without one checklist and severity system, minor issues consume repeated discussion while problems affecting inquiries, indexing, and security are missed.

Effective acceptance focuses on user tasks and business risks and identifies owners, test environments, issue levels, and closure criteria. This checklist suits corporate websites, brand websites, and B2B marketing sites. Systems involving transactions, accounts, or sensitive data require deeper security and business testing.

01 Establish Issue Severity First

02 Content and Brand Information Checks

• □ Company name, Logo, contact details, address, legal entity, and copyright year are accurate;
• □ Navigation, breadcrumbs, buttons, footer links, and return paths contain no broken links;
• □ Services, products, cases, news, and team information are final, with no test copy;
• □ Heading hierarchy is clear and every page has one primary H1;
• □ Images are clear and appropriately sized; important images have alternative text and decorative images use empty alt text;
• □ Fonts, images, video, icons, and customer Logos have valid usage rights;
• □ Chinese, English, numbers, dates, punctuation, units, and brand terminology are consistent;
• □ Empty content, unfinished sections, and modules that will not be maintained are removed or hidden.

03 Page and Responsive Checks

Do not test only at design-file dimensions. Cover common phones, tablets, laptops, and large screens and use real content: long headings, long English words, extreme numbers, missing images, and numerous tags.

04 Function and User-Task Checks

• □ Core tasks such as contact forms, appointments, search, filtering, downloads, and login can be completed end to end;
• □ Required fields, format rules, error messages, and success messages are clear;
• □ Duplicate submissions, timeouts, network loss, refresh, and back-navigation behave reasonably;
• □ Form email, CRM, SMS, and back-office systems receive data with correct field mapping;
• □ Downloads exist, have clear names and correct versions, and contain no sensitive information;
• □ Third-party maps, chat, video, analytics, and social links work;
• □ 404, unauthorized, empty-data, loading-failure, and maintenance pages are prepared;
• □ Back-office publishing, editing, deletion, sorting, and permissions match actual operating needs.

05 SEO Foundation Checks

06 Performance and Page-Experience Checks

Review both laboratory tests and real-user data. Google's current good thresholds for Core Web Vitals include LCP within 2.5 seconds, INP under 200 milliseconds, and CLS under 0.1. They are neither the only quality standards nor a ranking guarantee, but they help identify loading, interaction, and layout-stability issues.

• □ Compress hero images, video, and fonts; do not load unnecessary large assets on mobile;
• □ Lazy-load below-the-fold images appropriately without delaying critical resources;
• □ Give images, video, and embeds explicit dimensions to prevent layout shifts;
• □ Third-party analytics, chat, and advertising scripts do not block core content;
• □ Core tasks remain possible on weak networks and midrange phones;
• □ Configure caching, compression, CDN, and static-asset version strategies;
• □ Review important pages with PageSpeed Insights/Lighthouse and real devices.

07 Security, Privacy, and Compliance Checks

• □ HTTPS works sitewide, with valid certificates, redirects, and no mixed-content issues;
• □ Back office, servers, domains, code repositories, and third-party platforms use corporate accounts and least privilege;
• □ Forms and APIs include input validation, rate limiting, spam prevention, and error handling;
• □ Admin systems have no default passwords, and former-employee and test accounts are removed;
• □ Privacy policy, Cookie notice, and consent match actual data collection;
• □ Sensitive data does not enter front-end source, public logs, URLs, or analytics;
• □ Backup, recovery, monitoring, logging, and security-update ownership are clear;
• □ Payment, healthcare, finance, and other specialized operations complete appropriate professional compliance and security reviews.

08 Analytics, Conversion, and Operations Checks

09 Launch Deployment and Rollback Checks

• □ DNS, domain, SSL, server, and CDN changes have scheduled times and owners;
• □ Production environment variables, email, payment, and third-party APIs differ from test environments;
• □ Back up databases and the old site before launch and retain a recoverable version;
• □ Test 301 mappings from old to new URLs so important backlinks remain valid;
• □ Technical, content, and business owners are on call during the launch window;
• □ Define P0 rollback conditions, steps, and permissions;
• □ Schedule checks at 24 hours, 7 days, and 30 days after launch.

10 Final Handoff and Ownership Checks

• □ Deliver design source files, front-end/back-end source, databases, and deployment documentation under the contract;
• □ The company controls domain, server, CMS, analytics, search-platform, and third-party accounts;
• □ Licensing inventories for fonts, images, plugins, SDKs, and open-source dependencies are complete;
• □ Administrators, editors, support staff, and technical staff complete basic training;
• □ Maintenance scope, Bug submission, response methods, and new-requirement processes are clear;
• □ The issue list has final statuses, and every open item has an owner and due date.

Frequently Asked Questions

Who should own website acceptance?

At minimum, business/content, design, development, and project owners should participate. Security, privacy, legal, and SEO specialists should review their areas when relevant.

Must every P2 and P3 issue be fixed before launch?

No. P0 and P1 issues generally block launch. P2 and P3 items may enter an explicit post-launch backlog based on risk, but cannot be forgotten.

Is testing only in Chrome sufficient?

No. Cover mainstream browsers, operating systems, and real devices used by the target audience, especially mobile Safari, Chrome, and common enterprise environments.

Does Lighthouse need a score of 100 before launch?

Do not pursue a cosmetic perfect score. Prioritize core tasks, real-user experience, key metrics, and business risk, then continue optimizing.

Is acceptance still needed after launch?

Yes. DNS, cache, third-party APIs, analytics, and search crawling can be fully validated only in production. Review immediately and again at planned intervals.
