1. Website Design and Development: Web development companies design and develop websites from scratch. This involves creating layouts, selecting color schemes, choosing typography, and structuring the website’s overall appearance. They use various programming languages (like HTML, CSS, JavaScript, etc.) to build the website’s front-end and back-end components.

2. Custom Web Application Development: Beyond simple websites, web development companies also create complex web applications tailored to specific business needs. These applications can be anything from e-commerce platforms to customer relationship management (CRM) systems.

9. Web Security: Ensuring the security of websites is a significant aspect of web development. Companies implement security measures to protect websites from hacking, data breaches, and other cyber threats.

10. Analytics and Reporting: Tracking website performance is essential. Web development companies might set up analytics tools to provide insights into user behavior, traffic patterns, and other important metrics.

In essence, a web development company combines design, coding, and technical expertise to create functional and visually appealing websites and web applications that cater to their clients’ specific needs and goals.
