What are the differences between the SEO section and the META section of a pages settings?  I thought the seo info such as title, description and terms were the meta tag information.  What am I missing and what is recommended to be completed?  I know that overall meta data such as description and terms are not nearly as important as they once were but I still like to complete them in case teh powers that be (google) still find some value in them.  

I would be curious to learn what others think here as the "norm".  thanks.  Mike.
