Whether you're writing a sales page, email, or VSL, the most powerful tool isn't fancy words it's psychology.
The highest converting copy is built on psychology.
Great copy understands how people think, their desires, fears, beliefs, pain point and decision making process, and your copy stops feeling like marketing and starts feeling like the obvious next step.
People buy based on emotions and a good copy justify it with logic.
Psychology turns attention into action. Action turns viewers into buyers.
