Help me make $50 with a CPA network and $12

Hello! I recently got accepted to OgAds. Im going to use this website to make startup capital for an online business I have in mind. The problem is that I don't have many ideas on how to promote these CPA offers. What would be a good way to promote offers?

I have $12 in my paypal account, I could use them to invest on promoting.

That really depends on the offer you are trying to promote. If you have no money to advertise, I would google questions and offer the product as a solution to a related question.
