Personal blogs or portfolio websites are often more affordable because they focus on content delivery and branding. Key costs include domain registration, hosting, and a basic design that can be built with drag-and-drop builders or customizable website templates. For better usability and search engine optimization (SEO), you may also want to consider adding plugins for enhanced UX/UI, such as those for WordPress. Technologies like HTML5, CSS, and JavaScript help improve responsiveness and interactivity, making the website both intuitive and engaging.
