Welcome to the Q&A Forum

If you're referencing this site:
http://eldercareabcblog.com/recognizing-the-differences-between-the-normal-effects-of-aging-and-dementia/

Then take a look at your HTML as I saw many links.
For the URL above, most links seem to be in the 'Sponsors' area and the 'Archives' & 'Categories' areas.

I do think landing pages for each sub category are the way to go.

Interesting stuff. Just a few questions:

How many itemprops are needed in order to be listed by Google? I counted 10 one one of the pages.

In your experience how long would it take before Google picks up on the changes and displays them?
