It brings the market to you at your comfort and also sells people's products virally, especially if such products are truly needed by people, perhaps they solve problems or are needed or even cheap. Nothing can ever be compared to this because you might be at the remotest place in a very low-life environment and your products must have reached the entire world, which is awesome.
Digital marketing has truly revolutionized the way people promote their products and services. You are right about this. There used to be a time when companies and brands used to run commercials either on television on radio stations to promote their products and services, but today, they mostly use online marketing to promote these things, and it turns out to be much better when it comes to conversions because as you said, almost every other person in this world is available online these days.
One of the most significant advantages of digital marketing is that brands can do targeted advertising. In the past, when television commercials were very popular, brands couldn't choose their audience, and anyone watching a show or a channel would see their advertisement, which meant they didn't know whether the commercial would bring many customers or not, but this has changed now.
Brands run targeted promotions that only reach people who are interested in the products and services they are offering, which increases the potential of getting more conversions.
