I'm working on a new site which includes a forum, and the forum will be a very significant part of the content of the site. Forum posts are only visible to signed in members.
I wonder if anyone has any recommendations/thoughts/experiences on handling forum posts in SERP if the posts are member only. Can we get google to index them as they'll have a lot of good content. They're member only partly because we want site signups and other member interactions and also because with the site structure it makes sense. The posts themselves are not secret or private etc.
Presumably if they can get indexed and into SERPs, a public non member will click the link and be prompted to the free signup.
Thanks for any tips and suggestions
