You probably have tried several digital marketing tactics without an actual marketing strategy. Meaning, you tried to do Social Media like Twitter, Facebook, Instagram, you tried doing Google Adwords, and updating content on your website and many other things. And you probably are feeling frustrated as you are NOT getting the results you want.
But you see all THAT is just different marketing mediums. Marketing Mediums are channels where you execute your Marketing Strategy. But What is your Vision? What is Your Goal? What do you want to achieve? Once you decide on that, then go and design your marketing strategy, and create a message that makes you stand out of the crowd. The message that shows why are you different from any other of your competitors. And only THEN you start posting THAT message on different marketing mediums.
