New Meta Tag Manager module
Announcements
Yes - site pages means pages that are NOT on a profile. If it was me, I would just add keywords to your site pages - they can be the same through out all pages.
I know there is going to be requests to make it so it can be specific to individual pages, but that would really increase the complexity of the module. If you have more detailed needs than the module provides, you can edit the meta.tpl to suit your needs to.
Hope this helps!
