My post here was about promoting offers directly, not through content lockers.
All offers I listed here are non incentive, this means you can use them in content lockers (in a regular way).
Anyway, since you're here and already asked, aside from promoting non incentive offers via direct links, I had most success with Link Locker and Content locker:) which sounds stupid but it's true
I used link locker to lock link to movie streaming website. Now when I mentioned it, I'll actually explain it in details how I did it, but it will be in a separate thread.
Now to content locker: I used it to lock football (soccer) live streams - I had a website ranked on first place of google for some most popular keywords in my language. However, the earnings were high only when Bosnian, Serbian or Croatian national team was playing. To keep it short, I would add fake video player on my website and content locker over it.
Don't judge me
I really redirected visitors to live streams or movie streaming websites after they completed the offer So, we both got what we wanted...
Of course, most live streams can be embedded on your website, but I simply didn't wanted to have any there since they're illegal, same for movie streams.
