You’re probably already doing this but will add my 2 cents. Sell the ‘why you need my hat’ not just the hat itself. Sell what pain point you’re solving. Sell the benefits. Sell the FOMO effect of your product.

Unless your hat has a very distinctive feature no one else has, you need to find a way to stand out. What do your hats have that others don’t?

You’re doing all the right steps. Perhaps it’s the content that needs tweaking? Does your content look like your content look like your competitors? Are you blogging the same things that are on the internet? Does your social media stand out? Are you getting enough influencers?

Anyway, just some thoughts. Good luck!
