I run Xenforo. I'm considering disallowing: /posts/ /find-new/ /members/ but have not yet. Two questions: 1. Should these be disallowed? 2. What should I do if a large amount of threads with /posts/ in the URL are indexed by Google? Surely removing them will have a negative impact, at least short-term, for posts already indexed. They'll be deindexed, reducing any traffic they were bringing in, and possible GWT errors. On the other hand, can I test if they're being treated as duplicate content? What would you do? I realize blocking /posts/ is probably best practice and should have been implemented some time ago. 3. What should I be looking at in GWT?
