One way to identify your pain points can be as simple as meeting with your team to discuss what makes their day — and the customer’s day — harder. By anticipating what your customers are struggling to find on their own, you can potentially solve their problems before they leave a voicemail or, at the very least, point them in the right direction. This will help ease your own pain by making the experience easier for the client to navigate, leading to a more organized process.

If you want a customer to perform a specific action, you need to pay close attention to how you express your calls-to-action.
