I agree with this totally. I am currently working on setting myself up on evergreen webinars that I will offer for FREE.
I think that this does help build your brand and establish your status as a subject matter expert.
Create a demand for your service by giving a lot of information about the “what” and the “why” but less than generous with the “how”. This is how you then sell a coaching service of a done-for-you solution.
Like aI say this is merely my theory and I am currently working on creating my content to see if I can pull this off.
