SEO plugins for nodebb

Question posted in the subject.

Is there any must have plugin for search engine optimization?

The second question as an update for this topic is: how do I add a trailing slash to the URI of an arbitrary topic?
Raw nginx rewrite as follows doesn't do the trick

rewrite ^([^.]*[^/])$ $1/ permanent;

Update:
I need trailing slash in order to eliminate page_with_redirect issue.
