1. Write content that helps your market and can include a line saying for more info- fill in details (one option)
2. No matter what you do you cannot avoid competitors they are part and parcel of running a business. What you do have to remember clients are paying for you, not the information because with enough googling people can pretty much figure a lot out on their own. The people who would copy and or steal your IP are not your clients anyway. They would not pay you anyway so not worth worrying about. A really good example is Tesla who has open-sourced all their development and still maintaining a competitive edge
3. Look at what your aim is when creating these templates/ or pieces of content. Is it information to build authority or is to acquire leads by getting them on your mailing list and from there intro them to all your services.
