Marketing strategies in the digital era are no longer focused on marketing on television, radio, newspapers, magazines or similar. But marketing activities are already carried out through online platforms to promote business products or services. This involves the use of various digital channels such as search engines, digital social, websites and emails to achieve marketing goals.
You are right, the advantages of marketing strategies in this digital era have a wide reach and can even reach between countries so that the products marketed can be known more widely, especially now that almost everyone uses the internet. As far as I know, the types of strategies are also diverse, such as google ads, meta ads, SEO/SEM, email marketing, and influencers.
It depends on what you're selling, if you're going to do it wrong in marketing, that's when you are going to be not trying to put an ad on everything that people can see, sure it's the digital age but people are still watching the television and if there's someone out there that only has a television for you then it would be a missed opportunity for you if you don't have the television ads covered, even the radio one because you're going to still see people listening to that one, the only advantage of a digital era marketing is that you can just get more people including those outside of your country.
