Social Media Companies (META, SNAP, PINS, etc.) and advertising

I am doing some research on some of the social media stocks and I had a question that I could not find an answer to. Thus, I turn to the wise Reddit community. If I click on an ad on Snapchat for the Disney bundle for instance, and convert on the ad and become a subscriber, does Snap get a piece of the revenue of my subscription? Do all the companies keep/not keep a percentage of the revenue or is it different by company? Thanks!
