I dont know how you get in on joining the Ad Break Partner program… it seems like a numbers game. So having your number of views makes sense to go for that:
“The publisher that projected $264 for every million video views on Facebook said it expects $2,200 for every million video views on YouTube. For them, a Facebook video view is essentially worth 12 percent of a view on YouTube.”
“Sources expect the ad breaks product to remain a slow burn for both Facebook and publishers in the program. Sources said Facebook is still cautious in terms of how often it delivers an ad inside an eligible video. Based on its internal numbers, one publisher estimated that Facebook is only serving ads inside one out of every three video views that are eligible for an ad break.”
According to this article i linked below, they’re still testing it:
Advertisers are still waiting for Facebook to deliver benchmarks for a successful use of Facebook ad breaks.
"For publishers trying to make money with Facebook mid-rolls, it’s still a volume game and the platform remains volatile as some videos can capture tens of millions of views and along with it, a decent amount of revenue — while others bring in pennies.’
