Hello,
Dont know if you already used jreviews extension, its one of the advanced in handling and using content data,
One of its features is auto generating some meta information based on custom fields, categories, etc.
For example instead of having "Listing A" title for a listing we can auto generate it and it became "Listing A in Category B based in Alabama region".
What i am suggesting is an option to let admins choose some parameters and generate META information for users and events, here an example :
Instead of "John DOE" as title for profil we can have "John DOE, math teacher from New York region"
we will have a very smart and dynamic pages meta information generated automatically from already existing data.
hope it make sense
