Growing your business without marketing is possible. However, it is not ideal. Your business needs 5-6 sources of revenue for growth. Marketing is part of that solution. Investment in marketing will help your business grow.
The key to marketing goes beyond the digital marketing tactics you choose. Your marketing should start with a reason, the reason you started your business in the first place.
Do you ever ask yourself why your marketing is not working or why is it so hard to run this darn business? Sure, I think we are all asking these questions. I know I am asking this daily. Over the years I have tried multiple sales and marketing tactics that have worked and some that have not worked.
