What content would my target audience be interested in?

Hello,

I'm selling a product .. similar to a mouse pad, but for the arms.
Now, after doing plenty of keyword research, I've got a huge list with good keywords and most likely 3 or 4 customer groups that could be interested in my product:
1. Employees with a computer job
2. Gamers
3. People with skin issues / allergies
4. Private people who want more comfort at the computer

What I'm lacking of, are good ideas for content / content strategy. Sure .. stuff like work place ergonomics, skin…

What content would my target audience be interested in?
