Comment on WordPress SEO Tutorial by Rachel.
Have you used Robots Meta Plugin? https://wordpress.org/plugins/robots-meta/ I think it provides some of the features you’ve mentioned.
I’ve decided to file (present) all posts related to a specific category in a single page (in the specific category page).
It just make sense to me that readers will see all the ingredients at once (scrolling down the page) rather than sitting and browsing pages after pages.
