How to describe my meta data for WP blog?

I have a social media WordPress blog. I’d like for an expert to take a look at it and help me decide whether I should manually create meta data or let it be generated automatically. Also, if you know of a good plug-in for meta data, please share. I’m not allowed to post a direct link to the blog here, but if you’re willing to take a look, post here and I’ll send a link via PM. Thanks, Shoib
