As I have started to place more and more forums in the 'premium content' area, my site has dropped in page rank. When I check Google analytics I clearly see massive indexing issues with most of our posts.
Right now about 90% of our posts are in premium forums. Which means, 90% of our content is not indexable by Google or findable by people.
I'm trying to figure out a way where Google can index and notice ALL posts but prevent people from seeing more than the first 2-3 sentences. I installed the add-on that shows x-number of words but prevents people from reading the rest unless they register. This works great but the challenge is that even once they register, they are not a premium member yet. So the moment they become a free member, they now have access to premium content, which defeats the purpose.
Is there a way to make people choose a premium level at the same they sign up and until they upgrade they still won't see the content of the forums? Is there a way to get them to pay for the upgrade while, or right after, they register?
Are there any others who run a forum almost exclusively on premium content? How do you deal with this?
