Launching a website is more than clicking ‘publish’. Check that all content is accurate and finalized. Proofread thoroughly to eliminate typos. Test responsiveness on all devices. Validate all internal and external links. Ensure forms work properly. Optimize all images for performance. Double-check SEO meta tags and titles. Install and configure analytics tools. Set up backups and security measures. Confirm fast loading across pages. Test site speed with Google tools. Enable 404 and 301 redirects where needed. Submit XML sitemap to search engines. Finally, soft-launch to a test audience. Following this checklist helps ensure a smooth and error-free launch experience.
