Ideas for CPA Campaign?

Hey BHW, so I just got accepted into my first CPA Network, MaxBounty. I'm working on a new campaign right now and wanted to gather some insight here on the forum. I'm looking to promote an offer that pays on email submission. What types of traffic methods do you experienced CPA marketers use? I'm currently using a YouTube video that I got someone on fiverr to make about the offer. I place my link on the video and promote the link on social media. I also did some SEO on it as well. Any other methods you guys would recommend?

Get something that people want to download for free. A crack for a game, a free product or something else of value.
And use a content locker on your download. Or join 1 of the PPD networks and upload it. This will work in the same way as content locking
