Try the BING method. It was probably the third way I made money online that works.
1) You buy $100 BING coupons for $0.50-$1 each (you can find very cheap vendors if you ask around BHW)
2) Pick a pay-per-signup/SOI/DOI/PPL offer from your affiliate network that pays $2-$3 per sign-up.
3) Make a simple landing page with a single click through button in it. Put your affiliate link on the button. (You will need to cloak this with a URL shortener)
4) Create a bing account, attach your own real credit card ( A VCC WILL NOT WORK )
4) Add your $100 coupon code you bought to the account. It now has a $100 balance to spend !
5) Create an ad. Add your link to your landing page you made with the click-through button on it.
6) Pick the right keywords. It's simple. You have $100 to spend that cost you $0.50. You can afford to pay $1 and upwards per click and profit hugely still.
IE: If the offer you pick is one of those "Complete surveys to earn" offers, you will be targeting users wanting to make money. So pick keywords like "work online" or "online jobs" - these are mostly unemployed people or people who hate their jobs, desperately looking for a way to earn money working online. So you target them, they click your ad, titled "How to make money online doing surveys". They end up on your landing page, click through and end up on the offer. They signup and you earn $2 per signup.
This is simple. Just run your ads now and you will earn at least $30-$40 if you chose a good CPA offer that actually works. Don't be fooled by high paying offers on your network with a low network EPC. If the offer payd $5 per signup, but has a $0.03 network EPC there is a reason for that. It's a shitty offer!
Wish you luck. This is a template that works until the cows come home. ^^ if you put effort in, ie don't give up if things break once or twice, and purse for a day or 2, you'll make money. Guaranteed.
You may wonder why I stopped doing this? It's hard to get new credit cards. If you go into your banking app every week and click "I lost my card" and ship a new card weekly... the bank quickly starts asking questions lol
