Why Do You Need a Functionality Checklist?

A functionality check before website launch is non-negotiable. Even if the development phase includes multiple tests, performance may vary across different environments, browsers, or devices. A systematic checklist helps the project team verify each item, preventing oversight of critical features and minimizing the risk of post-launch problems. For corporate websites, which often involve brand image and customer conversion, functional stability is especially important.

Core Checklist Items

1. Basic Functions and Navigation

  • Ensure all page links are valid, with no broken links or incorrect redirects.
  • Navigation menus have a logical hierarchy, and click, hover, and expand actions work properly.
  • Search function: Entering keywords returns accurate results without errors.
  • Breadcrumb navigation: Position is correct, and the path is clearly visible.
  • Footer information is complete: Copyright year, ICP filing number, and contact details are displayed correctly.

2. Forms and Interactive Features

  • Contact forms, message boards, registration forms, etc., provide proper feedback after submission (success messages or error alerts).
  • Required field validation: Empty fields trigger prompts, and format errors (e.g., email format) are identified.
  • Submitted data is correctly stored or sent to the designated email/backend.
  • Interactive components like buttons, pop-ups, and carousels respond correctly on all devices.

3. Content and Media

  • Core pages such as Home, About Us, Products/Services, and News are complete with proper layout.
  • Images and videos load correctly without breakage or distortion; alt attributes are added (beneficial for SEO).
  • Text content has no typos, garbled characters, or formatting issues; layout is consistent.
  • Download links for PDFs, documents, etc., open or download correctly.

4. Compatibility and Performance

  • Test on major browsers: Chrome, Firefox, Safari, Edge display normally.
  • Mobile responsiveness: Layout adapts to different screen sizes, and buttons are clickable.
  • Page load speed: Use tools to check; homepage load time should ideally be under 3 seconds.
  • Images are compressed, and CSS/JS files are minified or combined (depending on the project).

5. Basic SEO Settings

  • Each page has a unique title and meta description.
  • URL structure is clean, avoiding Chinese characters or overly long parameters; use static or pseudo-static URLs.
  • A sitemap.xml is added and submitted to search engines (can be done post-launch).
  • robots.txt is configured correctly, without accidentally blocking core pages.
  • Each page has a single H1 tag that is relevant to the content.

6. Security and Compliance

  • HTTPS certificate is deployed, and the security lock icon appears when accessing the site.
  • Sensitive pages (e.g., admin panel, member center) require login authentication, and passwords meet strength requirements.
  • Form submissions include CAPTCHA or anti-spam mechanisms to prevent malicious submissions.
  • Legal pages such as Privacy Policy and Terms of Service are added (if required).
  • ICP filing information is displayed (mandatory for servers in China).

7. Backend and Permissions

  • Backend management functions work correctly: publishing articles, updating content, managing users, etc.
  • Permission settings are logical: admin, editor, and regular user permissions align with expectations.
  • Activity logs: Key operations are recorded for traceability.
Note: This checklist is a general reference. Adjust priorities based on the website type (e.g., e-commerce, corporate site, news portal). For example, e-commerce sites require additional testing of payment flows, shopping carts, and inventory management.

Recommended Inspection Process

Follow these steps:

  1. Create a checklist: Add or remove items based on the project's actual features.
  2. Divide testing: Developers, operations, and designers test their respective areas.
  3. Consolidate issues: Use project management tools or spreadsheets to record issues and fix statuses.
  4. Regression testing: Re-test after fixes to ensure no new issues are introduced.
  5. Dry run: Perform final validation in the live environment (or staging environment) before launch.

Throughout the process, testers should ideally not be the developers themselves to uncover potential blind spots.

Commonly Overlooked Items

Based on experience, the following are often missed:

  • Are error pages (404, 500) customized and user-friendly?
  • Is the favicon displayed?
  • Is the print style sheet available (some users may print pages)?
  • Are social sharing tags (e.g., Open Graph) added (if needed)?
  • Are third-party tool codes (e.g., analytics, live chat, ad conversion) deployed and functioning?

Conclusion

Website launch is not the end but the beginning of ongoing operations. A comprehensive checklist makes the launch process more controllable and reduces customer experience issues caused by overlooked details. It is recommended to refer to this checklist during every redesign or feature update. If the team lacks testing resources, consider seeking professional website maintenance services for assistance.
