We can't make the pandemic, or the recession, magically go away. But investing in marketing now can help mitigate the damage it does to your business.
Every business is unique. So while your goal may be the same as that of every other business owner (e.g. survival), how you do that is going to be unique to your situation, to your resources and to your particular market.
The fact is that what works for someone else isn't the same as what's going to work for your company.
But whatever you do, don't just sit home and watch Netfix. Ramp up your Marketing. Or at least rub a lamp.
