Re: Group forums meta data
Since this relates to bbPress specifically, I would ask this question in the bbPress forum.
To have the topic title as the page tittle, the topic first post as the meta description and the tags as the keyword would be ideal and really boost the seo of the forum posts.
You should first focus on all the other things that have the greatest SEO impact (like creating quality content).
Since you cannot control the content of your forums–it is generated by all your users after all–I think the best SEO booster for bbPress was just implemented by Sam. See this link: https://buddypress.org/forums/topic/buddypress-forums-now-use-pretty-permalinks
