What is Digital Marketing?

Digital marketing is the process of promoting products, services, or ideas using the internet and digital platforms. Unlike traditional marketing methods such as TV ads or billboards, digital marketing happens where people spend most of their time today, like Google, social media, websites, and mobile apps. 

It allows businesses to target specific audiences, measure performance instantly, and build stronger connections with customers. 

It covers many activities like improving a website’s visibility through SEO, running paid ads on Google, posting engaging content on Instagram or YouTube, sending promotional emails, and even collaborating with influencers or affiliates to reach more people.
