WWW HTTPS is properly configured

Properly configuring WWW and HTTPS for a website means setting up the website's settings to ensure secure access and data transmission. It includes enabling HTTPS encryption with a valid SSL/TLS certificate, implementing security measures like security headers, considering SEO practices, and optionally configuring redirection for consistency. This configuration enhances security, user trust, and website performance while providing a seamless browsing experience.
