Web development is the process of creating websites and web applications that run in a browser.

Think of a website as a house:

• Frontend: House’s appearance: walls, windows, doors.
• Backend: Internal systems: electricity, plumbing.
• Database: Storage for important data.

For example, in an online store, the frontend displays products, while the backend processes orders.

SEO is the process of improving a website to appear higher in search engines.

• Choosing keywords: Words people type into search engines (e.g., "buy a phone").
• Improving content: Articles should be useful and easy to understand.
• Optimizing speed: If a site loads slowly, people leave.

If SEO is done well, your site will attract more visitors.

Web design is about creating the look and feel of a website.

• Choosing colors, fonts, and images to make the site visually appealing.
• Creating user-friendly navigation for better UX.
• Making the site responsive for all devices.

For example, if buttons are too small or text is hard to read, users won’t stay on the site for long.
