I want to create modules on Wordpress to teach people how to run a retail business better in a small niche fitness studio.
> sales (converting visitors into buyers)
> marketing (getting noticed, bringing interested people to the point of having a buying conversation with you; includes everything from email campaigns to events)
> display design (merchandising, eg. water bottles)
> training/coaching (how you run a class/session)
> hiring (what staff you need, how to filter for the right candidate)
> bookkeeping (keeping track of income and expenses; knowing the score)
> profitability (how to get the most profit out of your operation)
These are just off the top of my head. They are main categories which you can drill down into for specific topics.
