I still don't understand exactly what you're asking. Each page can access the keywords and description in the application like this:
Me.Master.Keywords = "My Key Words"
This is shown in the page ProductDetails.aspx under ContentFiles.
When you set the keywords on the master, they eventually end up in the final HTML in the browser. So, yes, they do get picked up by search engines because they are part of the HTML.
However, if you have a dynamic page where users have to select something (e.g. trigger a post back based on, say, an item in a drop down list) search engines won't be able to follow the page, and so they'll never see the keywords.
Does this help?
If not, can you describe in much more detail what it is that you need?
