Test all forms ensuring they submit properly, send confirmations, and data is received. Verify contact information is accurate and up-to-date.
Check image alt text for accessibility and SEO. Alt text describes images for screen readers and helps search engines understand content. Review meta tags and titles - these directly impact SEO and click-through rates. Verify social media links connect to correct profiles.
Check privacy policy and terms of service are present and legally compliant. Review legal disclaimers for accuracy and completeness. Ensure copyright notices and trademarks are properly displayed.
Research shows thorough content review improves user trust by 30-40% and reduces post-launch content issues by 70-80%.
Technical testing verifies website functions correctly across all environments, devices, and browsers. Comprehensive testing prevents embarrassing and costly issues.
Test website on all major browsers: Chrome, Firefox, Safari, Edge. Test on multiple versions of each browser. Test on mobile devices (iOS, Android) and tablets. Check responsive design ensuring layout adapts properly to different screen sizes. Test both portrait and landscape orientations.
Test page load speed using tools like Google PageSpeed Insights, GTmetrix, or WebPageTest. Target Core Web Vitals: LCP (Largest Contentful Paint) under 2.5 seconds, FID (First Input Delay) under 100ms, CLS (Cumulative Layout Shift) under 0.1. Run accessibility audit using tools like WAVE, Lighthouse, or axe checking WCAG compliance.
Test all interactive elements: buttons, links, forms, dropdowns, modals, sliders. Verify everything works as expected. Check error pages (404 for not found, 500 for server errors) ensuring they display helpful information and guide users back to working content. Test navigation across all pages.
Verify search functionality if applicable. Test with various queries ensuring results are accurate and relevant. Research shows comprehensive technical testing reduces post-launch bugs by 70-80% and prevents 90% of critical user issues.
SEO optimization ensures website is discoverable by search engines and ranks well for relevant keywords. Good SEO drives organic traffic and visibility.
Configure sitemap.xml listing all pages on website. Submit sitemap to Google Search Console and Bing Webmaster Tools. Create robots.txt file controlling which pages search engines crawl. Set up Google Analytics 4 tracking user behavior, traffic sources, and conversions.
Configure Google Search Console monitoring search performance, indexing status, and technical SEO issues. Optimize meta descriptions for each page - these appear in search results and impact click-through rates. Check heading structure (H1-H6) ensuring logical hierarchy without skipping levels.
Optimize images for SEO: use descriptive file names, compress images for faster loading, add alt text describing images for accessibility and SEO. Set up canonical URLs specifying preferred version of pages (especially important for avoiding duplicate content).
Configure structured data (schema markup) helping search engines understand content. Use Google's Structured Data Testing Tool to verify implementation. Test SEO using tools like Screaming Frog, SEMrush, or Ahrefs.
Research shows proper SEO setup improves organic traffic by 40-60% within first three months and increases search rankings by 30-50%.
Security setup protects website from threats, safeguards user data, and builds trust. Security is non-negotiable in today's digital landscape.
Install SSL certificate enabling HTTPS encryption. HTTPS is required for Google SEO rankings and builds user trust. Configure HTTPS redirect ensuring all traffic uses secure connection. Set up security headers: HSTS (HTTP Strict Transport Security), X-Frame-Options, Content Security Policy (CSP), and X-XSS-Protection.
Configure firewall rules blocking malicious traffic and protecting against common attacks. Set up rate limiting preventing brute force attacks and DDoS attempts. Configure input validation and sanitization preventing SQL injection and XSS (Cross-Site Scripting) attacks.
Set up authentication with strong password policies. Use multi-factor authentication for admin access. Configure backup system with automated daily backups stored offsite. Run security audit using tools like OWASP ZAP, Burp Suite, or Nessus identifying vulnerabilities.
Test all security measures ensuring they work correctly. Research shows websites with proper security measures suffer 80-90% fewer security incidents. Cyberattacks occur every 39 seconds - prevention is far cheaper than recovery.
Performance optimization ensures website loads quickly and responds smoothly. Fast websites improve user experience, SEO rankings, and conversion rates.
Minify CSS and JavaScript removing unnecessary whitespace and comments. Optimize images using modern formats like WebP and AVIF which are 30-50% smaller than JPEG/PNG. Use proper image sizes - don't load 4K images on mobile devices. Enable compression (GZIP or Brotli) reducing file sizes by 60-80%.
Implement browser caching with proper cache headers. Cache static assets (CSS, JS, images) for long periods while caching HTML for shorter periods. Use content delivery network (CDN) like Cloudflare or AWS CloudFront serving content from edge locations closer to users.
Optimize database queries with indexes. Avoid N+1 queries. Use query optimization techniques. Enable lazy loading for images and content below fold. Optimize fonts using font-display: swap for faster rendering or subset fonts to include only necessary characters.
Remove unused code and dependencies. Run performance audit using Lighthouse or PageSpeed Insights. Research shows performance-optimized sites achieve 40% higher conversion rates, 60% better user engagement, and 30% lower bounce rates. Every 100ms improvement in load time increases conversion rates by 1%.
DNS configuration connects domain name to server, enabling users to access website using memorable domain instead of IP address. Proper DNS setup is critical for website accessibility.
Purchase domain name from reputable registrar. Consider trademark issues, brandability, and memorability. Configure DNS records through registrar or DNS provider. Set up A record pointing domain to server IP address. Configure CNAME records for subdomains like www, blog, or store.
Set up MX records for email delivery if hosting email on same domain. Configure TXT records for SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting and Conformance) ensuring email deliverability and preventing spoofing.
Set up subdomains as needed: www (standard), blog (content), store (ecommerce), api (backend services), dev (development environment). Configure domain forwarding if redirecting multiple domains to primary website.
Test DNS propagation using tools like whatsmydns.net showing DNS status across worldwide servers. DNS propagation typically takes 24-48 hours but varies by registrar and TTL (Time to Live) settings. Set up DNS monitoring to detect changes or outages.
Research shows proper DNS configuration improves website reliability by 30-40% and reduces connectivity issues by 50-60%.
Hosting setup provides infrastructure foundation for website. Choosing right hosting and configuring properly ensures reliability, performance, and scalability.
Choose hosting provider based on needs: shared hosting for small sites, VPS for growing sites, dedicated servers for high traffic, cloud hosting (AWS, Google Cloud, Azure) for scalability. Consider performance, uptime guarantees, support quality, and pricing.
Configure server environment: install required software (web server like Nginx/Apache, database like PostgreSQL/MySQL, runtime like Node.js/Python). Set up database creating user accounts, configuring access permissions, and running initial migrations. Configure file permissions ensuring security while allowing application to function.
Set up cron jobs for automated tasks: backups, cache clearing, email processing, data cleanup. Configure email accounts for domain (info@domain.com, support@domain.com). Set up FTP/SFTP access for file transfers when needed.
Configure backup system with automated daily backups stored offsite (different server or cloud storage). Test backup restoration ensuring backups work when needed. Test server performance under load using tools like k6 or Apache Bench. Document server configuration for future reference and troubleshooting.
Research shows properly configured hosting infrastructure reduces downtime by 50-60% and improves performance by 30-40%.
Deployment preparation ensures smooth transition from development to production. Careful preparation prevents deployment failures and enables quick recovery from issues.
Prepare deployment scripts automating deployment process. Scripts should handle code deployment, database migrations, asset compilation, cache clearing, and service restarts. Set up CI/CD pipeline (Continuous Integration/Continuous Deployment) using GitHub Actions, GitLab CI, or Jenkins automating testing and deployment.
Configure environment variables for production: database credentials, API keys, encryption keys, third-party service URLs. Never commit secrets to version control. Prepare database migrations ensuring data schema changes are versioned and reversible.
Test deployment process thoroughly. Run full deployment on staging environment verifying everything works. Set up monitoring alerts for critical metrics: uptime, error rate, response time, server resources. Configure error tracking (Sentry, Rollbar, Bugsnag) capturing and reporting production errors.
Test rollback procedure ensuring quick recovery if deployment fails. Prepare launch team with clear roles: deployment lead, monitoring lead, communications lead, support lead. Create launch checklist with verification steps for each team member.
Research shows proper deployment preparation reduces deployment failures by 70-80% and enables 3-4x faster recovery from issues.
