Help monetizing 2.4k visits/month site

Hello Fellas!
I am Allan, and I have a question that hopefully you can help me with.

I currently have a site in spanish on highly competitive niche, I think I am not even near to the first 20 pages in google, but I still get some generic traffic from it, even with my analizers I get from HIGH competitive keywords and when I search that keyword in google I do not see myself anywhere in google near to the first pages "its funny huh?"... Anyway, this is an informational site, I provide information about business and financial freedom and I have readers more than 90% are new people only 10% visit the site more than once according to google analytics, the adsense is giving me only about .50 cents a month so obviously is not working... I recently learned about the color theory so I changed the background on my google ads to yellow and the content is blue and I got 2 clicks in one day after doing that so I guess that will help a little, but apart from adsense what could be a good way to monetize my site?
I currently translated my site to english and I am posting the same information I have in spanish but with a different domain name and everything and I had 2 months below 400 visits but now in Nov it came up to be as of the 19th I already have 1,014 visits... yet adsense is low as well no clicks at all and I am using a theme that is specialized in adsense but still no luck with it,, what would you recommend for me to monetize this sites, because I do have unique visits but I can't find the way to correctly monetize it,, my main purpose of the site belongs to the following keywords in spanish and in english: "finance" "business" "financial freedom" "finance literacy"

Do you have any ideas that could help me out?
Thanks for your time to read this post!
