No amount of money will turn bad creative into good content.
You need to be producing and promoting quality content and getting it to your audience. If you can reach them without paying, great. But that’s not likely going to be the case anymore and you need to understand the need to invest in both creative and promotion if you want to grow your brand.
The great news is that when you do, you will start consistently turning strangers into loyal customers and brand advocates that have a compound effect on your success.
