QUESTION "meta id" OR "meta description"

[islander]

I would suggest you give it another try, as I dont think you looked at what the plugin outputs?

BetterSEO's name is just meant to say that it is better than the default GS seo.

All tags that you mentioned are given by BetterSEO, with the exception of "author". It adds "copyright" instead.
And as modern search engines no longer use keywords, this has been omitted.

"description" is added using the meta field, and if left empty, it will grab text from the page content field.

It also adds "robots", "last-modified", "canonical" as well as several optional sections.
