So I have like 10 videos that have more than 100k views. One has 800k. They keep growing everyday. My problem is, they are all in spanish language, so it only attracts people that speak spanish.

Is there something I could do to make money?

I currently have annotations and links to my main youtube channel where I get money from adsense, but since my main youtube channel is not same niche as the spanish one, I don't get too much traffic on my videos.

Find a spanish CPA zip/email offer and link it.

As someone else mentioned Spanish offers.

I tried it. Out of 170 clicks/impressions . No one bought anything. is 170 to 0 a good ratio?

find offer that convert well on specific country, ask your AM
