Need suggestions on optimizing a Mexican Website

Hey guys, one of my sites gets about 10k uv a day. Problem I'm having is that it's the lowest pcp (Games). Any suggestions on what I could try to do to maximize the earnings? On average the site will earn about $20 to $30 a day. All I have on there is adsense... My target age group is not the greatest either (Kids).

Suggestions?

You can also sell some ads space on your site .
For some extra income .
Or add some affiliate links.

If your target audience is kids, then why don't you add some offers from cpa companies specific for kids? Like games. This will surely increase your earnings. Give it a try.

I think you should also, try to find out the metrics for your website. Try to find out what the visitors are looking and searching. Maybe, you will get a new ideea for a new website or a new product. BTW, 20-30$/day is not bad. What traffic method do you use?

All the best.
