Web development involves designing, creating, and maintaining websites and web applications. It encompasses front-end development (user interface and user experience design) and back-end development (server-side programming, databases, and server configuration). On the other hand, a digital marketer focuses on promoting products or services using online channels, such as social media, email marketing, search engine optimization (SEO), pay-per-click advertising, and content marketing. Their goal is to increase brand visibility, drive traffic, and generate leads or sales through strategic online campaigns.
