Include a clean, responsive navigation header with your logo on the left, main category links in the center (e.g., Home, Shop, About, Contact), and user account, search bar, and shopping cart icons on the right. Use JavaScript or a framework to ensure the header remains accessible and sticky on scroll for easy navigation.
Integrate scripts that enhance user experience such as product filters, dynamic cart updates, promotional pop-ups, and analytics tracking. Make sure to optimize loading speed and mobile responsiveness to keep customers engaged.
