If your goal is to gate content until a user watches a YouTube video or clicks on ads (outside of AdSense), you’ll need to use some kind of content locker plugin, like WP Content Locker, Opt-In Panda, or custom JavaScript triggers tied to engagement events.
Just keep in mind that to make it look legit (especially if you’re simulating clicks or watch time), your traffic source matters a lot. This is where mobile proxies can be helpfu, they provide clean, rotating IPs that mimic real user behavior from different geos and devices.
As for ad networks, you’ll want ones that aren’t too strict on behavioral detection. Some alternative platforms tolerate incentivized actions as long as the fraud signals are low and the traffic looks real.
