Digital marketing involves promoting products, brands, and businesses through online channels like search engines, websites, and social media using tactics such as SEO, PPC, SMO, email marketing, and content marketing. Some advantages of digital marketing are that it allows businesses to spread worldwide more easily and inexpensively compared to print advertising, and websites are accessible 24/7 from anywhere. However, digital marketing requires a lot of time and dedication to produce and post content while managing pages, and there is a lot of competition so users may find what they need through other websites before reaching yours.
