Have you noticed this, too, when it comes to copy for course and membership websites, emails, and social media?
All of the sales messages sound the same. Or each business's website, social media, and emails rely on cute pictures and "personality" to sell. Or - the worst sin - the creators talk about themselves and not how their products help the customers looking for them.
I help teacher-entrepreneurs like you figure out what to say to your audiences so you create and maintain relationships with your readers and spend less time experimenting with marketing.
