Digital marketing is the use of digital channels, such as search engines, social media, email, and websites, to promote a product or service. The goal of digital marketing is to reach and engage with a target audience through the use of various digital tactics and strategies. These tactics can include search engine optimization (SEO), pay-per-click advertising (PPC), content marketing, influencer marketing, and social media marketing. Digital marketing allows businesses to reach a wider audience at a lower cost than traditional marketing methods, and it provides the ability to track and measure the effectiveness of campaigns in real-time.
