Informational vs transactional is what you're suggesting scooterdude? On my site I have many more informational pages than transactional ones (Google includes pages with affiliate links into this group).
To answer another question - My informational pages have no affiliate links (and are rocking in serps) but my transactional pages have anywhere between 1 and 5-6 affiliate links depending on number of related items. These pages Google is now nearly completely ignoring despite the fact that they also have information on them, written by me. That wasn't the case not too long ago.
I'm thinking a human downgraded this section of my site, there isn't much that could have been an "algo" besides the fact that yes there are links to a store on another site.
edit: links pass through a redirect page that filters bots and clicks from blacklisted IPs.
