The best way to start a headline is with an action word (or verb if you think back to high school English class). For instance, EARN 20% more, TAKE time to relax, FEEL better faster. These all start with an action word that stresses a change for the reader.
Focus on how your product or service will make your customer feel. While most of us like to think a purchase is made on logic, studies show that emotion plays a big role.
Customers feel good when your headline promises to remove something that is bothering them or add something that will make them feel wealthier, more relaxed or even sexier.
The thing to remember when developing your headline is to resist the temptation to be too cute. Your headline must be clear. Plain words often communicate your message best to hurried customers.
