vital membership versus free content – Which works best?

In the last 2 months, I stopped offering free advice.

the results are very clear!

  • strong increase in coaching clients
  • Clear increase as well in e-books sales.

Because I no longer offer my services free, people do sign up for coaching.

the question is:

Does the number of membership, coaching and overall sales respond in the same way when offering my content to members, or clients only?

This is one of the big possible steps that can be taken on the site.

Is this the way to go?

Would this generate the expected results?
