Google could log which sites have a paywall, and put an icon next to search result that you might need to pay money to access the article. I could also let google know which sites I subscribe to and if I have a WSJ subscription, it could rank those articles a little higher to similar results on sites I don't have a subscription to. For example, something similar happens when you google TV shows, e.g. https://www.google.com/search?q=mad+men https://www.google.com/search?q=mad+men There is a panel on the right hand side showing which streaming services stream the show. I can tell google which ones I have and it will improve the recommendations based on that.
