Currently I am using phpbb system, before I've had bbpress with wordpress. After coming into phpbb (no friendly urls, etc.), my positions dropped. Of course, website is reindexed but on wordpress I've been after keyword leader, after change...somewhere in shithole Content on my forum is really rich but I want to increase positions and search traffic. What I should to do? Change script? For what? BBpress is lack of features. Xenforo? Vbulletin? Invision?
