Promotion strategy depends on the industry in which your business operates, your goals, the amount you are willing to spend on online and offline promotion. I work for Filio Force in Canada. I would like to say that promoting a new business project and an established brand are different things.
It is important for a business owner to know the goals he wants to achieve in 6 months, a year, 5 years.
And the most important thing, of course, is to find professional contractors or hire an in-house employee.
