Keep It Simple and Stupid. What do your clients want to understand? Why do they want to understand? I can answer the second question here. They want to know if a product will solve their problem. Look for the mainstream fears and misunderstandings that prevent them from buying insurance. Be a salesperson and sell your medical insurance through honest information like facts and testimonies. Remember to fill your page with keyword rich words for search engine optimization.
Just do it. A good effort goes a long way. I know you'll polish up on really being understood in the long run. A client who understands is one who trusts the content and the name of the url. medicalinsurance.com is better than 123-medical-insure.com
Also, ask or advise the potential client to buy your product. This shows that you have confidence in what you are selling.
