Can you provide insights into how to iterate and optimize messaging based on performance metrics and client feedback?

It is the perfect time to iterate and optimize your messaging after you receive strong performance metrics and client feedback. This information will either validate your competitive advantage or highlight a new value prop that your clients clearly resonate with. Once you feel like your value props and messaging hierarchy (i.e. which points are the most important) align to the performance metrics and client feedback, you can use the data to beef it up. Your messaging framework should have a section for proof points. This is where you will add your performance metrics and client feedback. The client feedback should be in the form of a testimonial quote that has been approved by the client to use in marketing material. 

When you start using your messaging to craft webpages, sales assets, email campaigns, you can add the performance metrics right into your value prop to create an impactful headline. Example - “Clients increased revenue by 55% with Product A.” The customer testimonials can supplement this as well to provide social proof to your audience.
