How to restrict access to pages but still have my content indexed by Google?
Posted on 2016-10-17
I am building a guitar instructional website. It will have lessons, and quizzes to make sure you understand the lesson. I won't let someone move onto the next lesson until they have demonstrated that they understand the concepts that will be important later on, as music theory is cumulative.
How do I restrict their access to future lessons they haven't achieved access to yet while still allowing Google to index the page?
