What do you think which is the hardest part of marketing?

I think scaling while maintaining CPAs is definitely up there in my top marketing challenges

Understand what works and what doesn't work :)

I think the hardest part of marketing is staying ahead of the ever-changing trends. The digital landscape evolves so quickly, and consumer behavior can shift overnight. Keeping up with these changes while maintaining a consistent brand message and effectively reaching your target audience is definitely a challenge. Balancing creativity with data-driven strategies is key, but it requires constant learning and adaptation.

I'm scared of SEO :) Dont understand it and trying to stay away as from something unknown haha :D

It's a marathon. So keeping up the hard work for a long time before seeing results that are what you would expect!

Constant experimenting. Trial and error to see what works for you and your industry

Getting initial users and scaling but not too much.
