I have experience ghostwriting for a health site who produced health-based accessories. This included talking about the products they make and how they can improve the lives of the people they were targeted at. It required a lot of research into the condition the accessory was targeting and how it helped the customer. Once done, I then added what I learnt to my copy to let the readers know why the equipment was perfect for them.
The topics for the health site ranged across a wide variety of objects, from heart rate monitors to back braces to portable scooters. I also did some informative articles that tackled a specific area of health and gave readers a full in-depth explanation of every aspect of it.
