Your branding is the first thing a prospect sees and it does half the selling job for you. In the same way that many people can write well but not many can sell you a car, the same thing is true when it comes to marketing. Just because someone can write doesn't mean they can write something that sells.

Your current tagline is ineffective and does almost nothing with its 50% of selling power. You need to craft one that is effective at selling, otherwise you are leaving a lot of money on the table.
