1. Is this a good rule to follow?
I have a site that teaches Android programming and I do this through blog posts and online courses. One of my courses has a landing page that I take people to through Facebook ads. If I follow this rule they should only be able to see this page from the fb ad. I would then need another page to promote my course in the form of a blog post or another dedicated page. So that brings me to question 2.
2. What would be the best way to include this course on my site?
Thanks in advance, you guys rock.
